Dominant party rule, elections, and cabinetinstability in African autocracies

Abstract
I draw on the authoritarian institutions literature to explain the role of dominantparties in constraining the ability of autocrats to reshuffle cabinet ministers. Domi-nant party leaders are constrained in their ability to frequently reshuffle ministers bythe need to maintain credible power-sharing commitments with party elites. Theseconstraints also produce distinct temporal patterns of instability where large reshuf-fles occur following elections. Conversely, personalist leaders face fewer power-sharingconstraints and engage in more extensive cabinet reshuffles at more arbitrary intervals.Military leaders face complex constraints that depend on whether officers or civiliansoccupy cabinet posts and the extent to which leaders are dependent upon civilian min-isters for regime performance and popular support. Empirical analyses using data onthe cabinets of 94 authoritarian leaders from 37 African countries between 1976 and2010 support the theoretical expectations for dominant party and personalist leaders;but are inconclusive for military leaders.

African countries have a reputation for having the largest and most unstable cabinets in
the world. The size and instability of African cabinets has left some scholars to question
whether African ministers serve anything more than a ceremonial role, where ministers cap-
ture patronage but do not play a meaningful role as managers of the bureaucracy (van de
Walle, 2001). Recent scholarship enhances our understanding of why Africa’s cabinets have
grown over time as well as the economic impact of large cabinets (Arriola, 2009; LeVan &
Assenov, 2016; van de Walle, 2001). However, little research systematically analyzes the
instability of African cabinets.1 This is surprising given the number of anecdotal accounts
of cabinet reshuffles being used to undermine elites, the potential for cabinet reshuffles to
spark conflict between elites and leaders, and the detrimental impact of cabinet instability
on bureaucratic capacity. Furthermore, variation in cabinet stability, particularly among
Africa’s authoritarian regimes, is greater than is often recognized. This variation cannot
be explained using the unifying framework of patronage politics that guides most studies of
African autocracies.
Building on the literature on authoritarian institutions, I explain how regime type influ-
ences the ability of leaders to dismiss ministers without destabilizing their regimes. I argue
that leaders of Africa’s dominant party autocracies are more constrained in their ability to
dismiss cabinet ministers than are personalist leaders. These constraints reduce the extent of
minister dismissals by dominant party leaders as dismissals signal that years of loyal service
to the party will not be rewarded with meaningful power-sharing. The need to maintain
credible power-sharing with cabinet ministers also results in more distinct temporal patterns
of cabinet reshuffles by dominant party leaders compared to personalist leaders. Dominant
party leaders use elections as a mechanism to induce regularity in minister turnover, allowing
them to appoint a new group of party elites to cabinet positions while minimizing claims that
they are arbitrarily undermining the authority of ministers who have been dismissed. Con-
versely, personalist leaders are able to engage in more arbitrary patterns of cabinet shuffles
in both election and non-election years. Additionally, I argue that the extent of dismissals by
1
military leaders depends upon whether cabinets are composed of officers or civilians, and, if
the cabinet is composed of civilians, the extent to which the regime is dependent upon civil-
ians for regime performance and popular support. Military leaders with military cabinets
and those who are dependent upon civilian ministers for regime performance and popular
support should behave similarly to dominant party leaders.
I test my argument using an original dataset of cabinet ministers from 37 African au-
tocracies between 1976 and 2010. These data include yearly cabinet observations from 94
leaders of regimes classified as authoritarian by Geddes, Wright, and Frantz (2014). I find
that cabinet stability varies significantly across authoritarian regime types, with dominant
party leaders dismissing fewer cabinet ministers than personalist leaders. Dominant party
leaders also tend to engage in large cabinet reshuffles following elections while personalist
leaders engage in more arbitrary patterns of reshuffles in election and non-election years. The
results for military leaders are ambiguous for minister dismissals; however, military leaders
engage in more post-election horizontal reshuffles than personalist leaders.
This article makes several contributions. First, it qualifies existing accounts of elite
politics, patronage, and political stability in Africa. While I agree with Bratton and van de
Walle (1997) who argue that elite shuffles are used to “regulate and control rent-seeking,
to prevent rivals from developing their own bases, and to demonstrate power” (p. 86), the
ability of leaders to safely engage in reshuffles varies. This has implications for debates over
patronage politics and political stability, and helps to explain why, as Arriola (2009) notes,
patronage politics is frequently cited as a cause of both stability and instability. Although
Africa’s dominant party, personalist, and military leaders rely on patronage politics to build
and maintain coalitions, differences in regime type condition the extent of political instability
within the cabinet. This shows that formal institutions influence the behavior of leaders and
produce meaningful differences in political stability in African autocracies.
Second, I provide new empirical support for theories stressing the institutional roots of
authoritarian regime and leader stability. It is now well established that autocrats use in-
2
stitutions to co-opt elites and establish credible power-sharing commitments (Blaydes, 2010;
Boix & Svolik, 2013; Brownlee, 2007; Gandhi, 2008; Geddes, 2003; Magaloni, 2006, 2008;
Smith, 2005; Svolik, 2012). However, studies linking the presence of particular authoritarian
institutions to increased leader and regime tenure often make untested assumptions about
differences in coalition dynamics between regime elites and leaders. This study helps to
close the gap between the broad support for institutional theories of authoritarian regime
and leader stability and the coalition dynamics posited to explain differences in regime and
leader tenure. Additionally, it adds to existing research on authoritarian elections and elite
shuffles (e.g., Hassan, 2017; Magaloni, 2006, 2008) by highlighting the heterogeneous effects
of elections on cabinet reshuffles across regime types.
Third, this study advances the growing literature on authoritarian cabinets. Although
theories of cabinet durability in parliamentary and presidential democracies have been sub-
ject to significant cross-national evaluation (see Fischer, Dowding, & Dumont, 2012), rela-
tively few scholars have studied authoritarian cabinets cross-nationally. Furthermore, exist-
ing cross-national studies have not considered cabinet instability in the form of dismissals and
horizontal reshuffles (e.g., Arriola, 2009), how cabinet instability varies within autocracies
(e.g., Quiroz Flores, 2009), or whether authoritarian regime type influences leader decisions
to dismiss ministers (e.g., Francois, Rainer, & Trebbi, 2015a; Roberts, 2015). This study
provides a general theoretical framework through which studies of authoritarian cabinets can
be further specified and subject to greater empirical scrutiny.
The article proceeds as follows. First, I review explanations of cabinet stability found in
the literature on patronage politics and discuss how the broader literature on authoritarian
rule applies to cabinet stability in African autocracies. Second, I build the authoritarian
institutions literature to develop hypotheses on the extent and timing of minister dismissals
and horizontal reshuffles. Third, I introduce the cabinet data, the empirical model, present
the results, and discuss several robustness checks. Finally, I explain the implications of the
empirical analyses and offer suggestions for future research.

What explains cabinet instability?
Scholars have identified several factors that influence the stability of cabinets in authoritar-
ian regimes. First, particularly in African autocracies, cabinet instability is often attributed
to the practice of patronage politics. Patronage politics, which is often considered the or-
ganizing principle of African politics, is characterized by reciprocal, although necessarily
unequal, relations between leaders and their coalition of clients (Bratton & van de Walle,
1997; Clapham, 1982). The inequality within patronage arrangements arises from the leader’s
ability to condition continued access to state resources on political support. In resource poor
environments, this allows leaders to form broad coalitions of supporters, often spanning mul-
tiple ethnic groups (Arriola, 2009; Francois, Rainer, & Trebbi, 2015b; Lemarchand & Legg,
1972; Herbst, 2000).
As some of the most senior clients of leaders, cabinet ministers often reap substantial
benefits from their positions. Cabinet appointments come with many perks including high
salaries, cars, homes, policy influence, and opportunities for enrichment through corruption.
Access to patronage resources means that ministers can also develop their own patronage
networks (Barkan & Chege, 1989; Bratton & van de Walle, 1997). In his study of Houphouët-
Boiny’s Democratic Party of Côte d’Ivoire (PDCI), Zolberg (1969) argues that “regardless
of his specific duties as a member of the executive, each minister is also a kind of superrep-
resentative who keeps in touch with the country through his clientele of deputies” (p. 283).
Therefore, ministers, while accumulating patronage, are important for broadening the base
of regime support because of their ties to local and regional constituencies.
Ministerial appointments produce a paradox for leaders in patronage-based polities.
Leaders need the support of ministers and the constituencies they mobilize, which provides
incentives for cabinet expansion (Arriola, 2009). At the same time, cabinet appointments
provide elites with patronage resources that can be used to challenge the leader (Roessler,
2011). As Widner (1992) argues, “only a head of state who is exceptionally clever in his abil-
ity to elevate and demote the “barons” with who he allies himself–or keep them guessing–can
4
long maintain power” (pp. 55-6). In this view, cabinet reshuffles are a strategy of political
survival because they prevent ministers from building independent bases of power within
particular ministries that could be used to challenge the leader (Barkey, 1994; Bayart, 2009;
Chabal & Daloz, 1999; Jackson & Rosberg, 1982; Migdal, 1988; van de Walle, 2001).
Minister reshuffles, while undermining potential challengers, are not without costs. Lead-
ers that dismiss ministers and expel them from the ruling coalition risk elite splits and open
conflict. Roessler (2011) theorizes that sacking threatening regime elites, particularly those
of rival ethnic groups, exchanges coup risk for a future risk of civil war. For example, South
Sudan’s Salva Kiir sacked his entire cabinet in July 2013 following internal power struggles
within the South Sudan People’s Liberation Movement, particularly with Prime Minister
Riek Machar. Kiir’s decision sparked civil war between his government and those loyal to
Machar. Attempts to undermine regime elites and personalize power can also produce coup
attempts as remaining regime elites face an increasingly uncertain future (Svolik, 2012; Wig
& Rod, 2016). Recently dismissed ministers, such as former Liberian Minister of Rural De-
velopment Samuel Dokie, have coordinated with remaining regime elites to oust leaders. In
1983, Dokie organized a coup attempt against President Samuel Doe after reportedly being
dismissed for denying a request to transfer $3 million from the Ministry of Rural Develop-
ment to Doe’s personal account (Huband, 1998, p. 32). Mobutu unraveled a similar plot
before it materialized in 1966. In what was known as the “Whitsun plot,” recently dismissed
Premier Evariste Kimba and 3 other ministers were accused of plotting against Mobutu and
were publicly hanged (Dickie & Rake, 1973, p. 576). This is not to say that all ministers
possess the capability to mobilize civil wars or coups against incumbents. Particularly with
coups, mobilization against the incumbent typically requires discontent among members of
the military. Nevertheless, the cases from South Sudan, Liberia, and Zaire demonstrate
that some ministers are capable of mobilizing such actions. Furthermore, as Francois et al.
(2015a) state, military mobilization against the incumbent rarely takes place “without the
complicity of important civilian insiders like ministers” (pp. 2-3). Thus, the decision to
5
dismiss potential rivals from the cabinet non-trivial.2
Leader tenure provides a second explanation for cabinet instability. Leaders that have
survived longer in office may be less vulnerable to violent reprisals when undermining regime
elites. Scholarship on leader survival shows that authoritarian leaders face high initial risks of
being overthrown but become more secure in office as their tenure increases (Bienen & van de
Walle, 1989; Bueno de Mesquita, Smith, Siverson, & Morrow, 2003). Similarly, Svolik (2012)
argues that established autocrats who have survived the initial high risk period of their tenure
have fundamentally different relationships with regime elites than contested autocrats who
have recently entered office. Contested autocrats must share power with regime elites as they
are vulnerable to “allies rebellions.” Established autocrats have consolidated their authority
and can no longer be threatened by allies rebellions. As a result, “key administrators or
military commanders are periodically purged, publicly humiliated, rotated across posts, or
dismissed and later reappointed” (Svolik, 2012, p. 79). Cabinet reshuffles may, therefore, be
a function of leader tenure.
Third, cabinet instability may be explained by the vulnerability of particular authoritar-
ian regime types to elite splits. Leaders of regimes that are more vulnerable to elite splits
may limit cabinet change to prevent threatening rifts from emerging within their regimes.3
Geddes (2003) argues that the propensity of elite splits varies across dominant party, person-
alist, and military regimes. Dominant party regimes are defined as those where the ruling
party has “some influence over policy, control[s] most access to political power and govern-
ment jobs, and ha[s] functioning local-level organizations” (Geddes, 2003, p. 72). Examples
of African regimes coded as dominant party autocracies include the Socialist Party of Senegal
(PS) regime led by Leopold Senghor and Abdou Diouf and the Zimbabwe African National
Union-Patriotic Front (ZANU-PF) regime led by Robert Mugabe. Personalist regimes are
those where an individual leader controls personnel appointments and policy. The regimes of
Blaise Compaoré in Burkina Faso and Yahya Jammeh in Gambia are coded as personalist.4
Military regimes are those where a group of military officers influences policy decisions and
6
controls access to political power. For example, Geddes codes Justin Lekhanya’s regime in
Lesotho and Ibrahim Babangida’s regime in Nigeria as military.
Geddes expects the risk of elite splits to be low in dominant party and personalist regimes
and high in military regimes. Dominant party regimes, despite relying on broad coalitions
that often include rival factions, are able to minimize elite splits through their dominance
over the political system. Rival factions are discouraged from challenging the dominant
faction because doing so risks regime breakdown and thus the benefits from holding office in
a system monopolized by a single party (Geddes, 2003, p. 63). Similarly, Brownlee (2007)
argues that dominant party regimes “harness elites together” by reassuring “power holders
that their immediate and long-term interests are best served by remaining within the party
organization” (p. 39). Conflict between rival factions is thus prevented by mutual interests
in the continuation of the regime.
Elites splits are discouraged in personalist regimes by the leader’s control over patronage
and the security apparatus, as well as the exclusion of rival factions. As Geddes (2003)
argues, “As long as the dictatorship is able to supply some benefits and has a sufficiently
competent repressive apparatus to keep the probability of successful plotting reasonably
low, they [regime elites] will remain loyal” (p. 63). Similarly, Bueno de Mesquita et al.
(2003) argue that authoritarian regimes with small winning coalitions, which include many
personalist regimes described by Geddes, encourage loyalty between regime elites and the
leader. Although elites in small winning coalition systems have access to substantial private
resources, they are discouraged from using those resources to challenge the incumbent be-
cause the likelihood of successfully challenging the leader and being included in a subsequent
small coalition system is small.
Conversely, Geddes argues that military regimes are vulnerable to elite splits that emerge
over personal rivalries or policy differences. When rival factions emerge within military
regimes, soft-line factions within the regime will voluntarily exit politics and return to the
barracks in an attempt to preserve military unity (Geddes, 2003). Since returning to the
7
barracks allows the majority of officers to continue their military careers and experience
improved post-tenure fates (Debs, 2016; Geddes, 2003), other factions follow the first move of
soft-line factions and return to the barracks as well. The vulnerability to elite splits, interests
in maintaining unity within the military, and improved post-tenure fates for voluntarily
returning to the barracks thus explains the short tenure of military regimes (Debs, 2016;
Geddes, 2003; Kim & Kroeger, 2017).
On its own, Geddes’s discussion of elite splits suggests that both personalist and domi-
nant party leaders should face lower risks of elite splits after cabinet reshuffles than military
leaders. However, Geddes (2003, pp. 53, 60) only mentions that personalist leaders en-
gage in frequent elite shuffles. Personalist leaders are expected to utilize elite shuffles to
undermine challenges from rival factions and capture greater rents for the majority faction.
Conversely, elite shuffles in dominant party regimes are mentioned only tangentially. For in-
stance, Geddes’s (2003) game theoretic account of politics in dominant party regimes shows
that excluding rival factions is risky “because exclusion gives the minority an incentive to
try to unseat the majority” (p. 59). While Geddes’s theoretical logic may be sound, its
application to the stability of authoritarian cabinets leaves an additional puzzle. The dis-
tinction between personalist and dominant party regimes by Geddes (2003) and Geddes et
al. (2014) is mainly based upon whether the leader or the party controls policy and po-
litical appointments. However, leaders of Africa’s dominant party and personalist regimes
retain formal control over cabinet appointments and dismissals. Even in Botswana, where
the Botswana Democratic Party (BDP) is highly institutionalized, the president has the
authority to appoint and dismiss cabinet ministers. In other highly institutionalized domi-
nant party regimes such as Tanzania’s Chama Cha Mapinduzi (CCM) regime, the president
makes cabinet appointments after consultation with the prime minister. Nevertheless, the
Tanzanian president can revoke appointments without the approval of CCM leaders.
The lack of formal control over cabinet appointments and dismissals along with Geddes’s
expectation that personalist and dominant party regimes are relatively resistant to elite
8
splits produces ambiguity over the expected patterns of cabinet shuffles in Africa’s dominant
party regimes. This contrasts with military regimes, where Geddes’s logic suggests that
threatening rivalries should emerge when leaders frequently shuffle officers out of cabinet
positions. In the next section, I build on studies of authoritarian institutions to explain the
relative constraints faced by dominant party, personalist, and military leaders when shuffling
ministers and how these constraints influence patterns of minister dismissals and horizontal
reshuffles.
Regime Type, elections, and cabinet instability
My explanation of cabinet stability in African autocracies focuses on the different power-
sharing dynamics between leaders and cabinet ministers in dominant party, personalist,
and military regimes. Rather than expecting cabinets in African autocracies to be similarly
unstable as in the literature on patronage politics, or that the relative resistance to elite splits
determines the extent of elite shuffling, I explain why dominant party leaders face greater
constraints on their ability to shuffle cabinet ministers than personalist leaders, and provide
several countervailing expectations for the constraints faced by Africa’s military leaders.
Furthermore, I expect more distinct temporal patterns in cabinet reshuffles in dominant
party regimes, with leaders shuffling ministers following elections to establish regular patterns
of cabinet turnover that reward new elites and serve as a bulwark against claims of failed
power-sharing.
Scholars of authoritarian regimes have begun to stress not only the importance of power-
sharing institutions, but also the credibility of power-sharing commitments between leaders
and elites (Magaloni, 2008; Svolik, 2012). Credible power-sharing commitments are most
important for dominant party leaders as their rule depends on their ability to co-opt broad
coalitions of elites. Elites, particularly those from rival factions, have few reasons to acquiesce
to co-optation into a regime that does not offer them increased patronage opportunities
and policy influence. Magaloni (2008) argues that parties solve this commitment problem
9
when they are expected to persist into the future and can “(a) control access to power
positions, spoils, and privileges; and (b) deliver on the promise to promote those who join
the organization” (pp. 723-4). Additionally, both Magaloni and Svolik emphasize that
credible power-sharing requires that elites can credibly threaten rebellion against leaders
who renege on power-sharing commitments.
Rather than focusing on power-sharing between leaders and elites broadly as do Magaloni
and Svolik, I focus specifically on the relationships between leaders and cabinet ministers.
As with Geddes’s definition of dominant party regimes, Magaloni (2008) suggests that the
party must control ministerial appointments and dismissals for power-sharing to be credible
within the cabinet. While this is not the case in the African regimes studied here, I argue
that dominant parties still constrain the leader’s ability to arbitrarily dismiss ministers. To
make power-sharing credible, dominant party regimes must establish a system of regular pro-
motion in exchange for party service. Party members must also be rewarded with meaningful
increases in patronage and policy influence as they rise through the ranks. Without a regular
system of promotion and increasing benefits, current and prospective members of the party
have few incentives to incur the “sunk political costs” at the lower levels of the party (Svolik,
2012, p. 163). The promise of promotion, policy influence, and patronage is particularly
important at the higher levels of the party as these individuals have invested the most time
and effort in party service. Few party elites can expect to be selected as the next leader, but
those that have risen through the party ranks are likely to expect cabinet appointments, or
other prestigious positions in parastatals or party committees, for their years of loyal service.
Because of the importance and prestige associated with cabinet appointments, leaders that
rapidly dismiss ministers send a public signal that political promotions at the highest level
do not provide meaningful power-sharing. This undermines the party at the upper and lower
levels. High ranking members realize that they can no longer expect meaningful political
promotion while lower ranking members, who often engage in the most costly party service,
begin to question whether their investment in the party will be rewarded. Thus, party mem-
10
bership begins to lose its appeal, creating splits among party factions and leading some to
challenge the incumbent by supporting rebellion or forming their own political parties.
Conversely, personalist leaders face lower risks of compromising their regimes by rapidly
shuffling ministers. Unlike dominant party regimes, personalist regimes do not depend upon
broad coalitions and are less reliant on the service of lower ranking regime members. Person-
alist leaders, having often gained their positions through intense struggles (Geddes, 2003),
implement a variety of coup-proofing measures to prevent successful rebellion against their
rule, including the recruitment and promotion of soldiers based on family, ethnic, or reli-
gious ties (Quinlivan, 1999). For example, most Togolese officers serving under Gnassingbe
Eyadema were coethnics of the Kabye ethnic group and many senior commanders were
from Eyadema’s home village (Decalo, 1989; Pilster & Böhmelt, 2011). Coup-proofing can
also involve counterbalancing military forces by creating rival factions or paramilitary units
(Quinlivan, 1999). Mobutu engaged in counterbalancing in 1974 when he replaced the uni-
fied General Staff with four separate departments under different leadership (Emizet, 2000).
Similarly, Blaise Compaoré established a separate Regiment of Presidential Security (RSP),
which served as an “army within an army” that was better equipped than the regular armed
forces (Chouli, 2015, p. 327).5 Furthermore, most elites will refrain from challenging per-
sonalist leaders so long as the leader maintains control over patronage distribution (Bratton
& van de Walle, 1997; Ulfelder, 2005). This allows personalist leaders to rapidly dismiss
ministers without facing an organized response.
The constraints on Africa’s military leaders are less clear. As Geddes describes, military
regimes are reliant upon power-sharing between the leader and a group of officers. While
this suggests that military regime cabinets should be relatively stable compared to those in
personalist regimes, it is not clear that this logic holds among Africa’s military regimes. This
is because the cabinets of Africa’s military regimes are often quickly “civilianized” (Anene,
1997), with military officers serving in the cabinet being replaced by civilian ministers.
Anene (1997, p. 63) argues that civilian cabinet appointments serve to improve government
11
effectiveness, address demands for civilian rule, and build bases of support separate from
the military.6 This “civilianization” process produces cabinet instability in the early years of
military regimes as civilians replace military officers. However, it is unclear whether military
leaders face the same power-sharing constraints with civilian ministers as they do with high-
ranking officers. For instance, civilian ministers are less able to punish military leaders who
engage in frequent cabinet reshuffles than are military ministers, which could result in more
extensive and frequent cabinet reshuffles. At the same time, Anene’s (1997) argument that
civilian ministers improve government effectiveness, accommodate demands for civilian rule,
and build support outside the military suggests that military leaders may be dependent upon
power-sharing with civilian ministers as well, resulting in fewer cabinet reshuffles than in
personalist regimes. Although existing theory is ambiguous about the stability of cabinets
in Africa’s military regimes, empirical analyses can help to explain the extent to which
Africa’s military leaders are constrained by power-sharing commitments with ministers. If
the lesser ability of civilian ministers to punish military leaders is most important, patterns
of cabinet reshuffles by Africa’s military leaders should be similar to those of personalist
leaders. Alternatively, if Africa’s military leaders are dependent upon civilian ministers for
regime performance and popular support, they should engage in patterns of cabinet reshuffles
that are more consistent with dominant party leaders.
The discussion above produces several testable hypotheses. First, despite arguments that
dominant party regimes face a low risk of elite splits, I argue that dominant party leaders
dismiss fewer ministers than personalist leaders. Given the theoretical ambiguity over the
reshuffling behavior of Africa’s military leaders, I seek only to test whether they behave
similarly to either dominant party and personalist leaders, following the countervailing logics
described above. These arguments produce Hypothesis 1:
Hypothesis 1: Dominant party leaders dismiss fewer ministers than personalist
and military leaders.
While Hypothesis 1 examines differences in rates of minister dismissals across author-
12
itarian regime types,7 it does not predict the extent to which leaders horizontally shuffle
ministers between ministerial portfolios. This distinction is important as dismissing min-
isters often provides a different signal to regime elites than does horizontally reshuffling
ministers. Horizontal reshuffles provide a middle ground between dismissing problematic
ministers and allowing them to continue developing power and autonomy within a particular
portfolio, and provide a mechanism to reduce ministerial moral hazard. (Huber & Martinez-
Gallardo, 2008; Indridason & Kam, 2008). I expect all authoritarian leaders to use horizontal
reshuffles to reduce ministerial moral hazard and that overall rates of horizontal reshuffles
are similar across regime types. While the relative lack of power-sharing constraints faced
by personalist leaders may be expected to result in more horizontal reshuffles, I argue that
this simply allows personalist leaders to engage in more dismissals instead, with horizontal
reshuffles reserved to check the power and autonomy of close allies who remain in the cabinet
for longer periods of time. This leads to Hypothesis 2.
Hypothesis 2: Dominant party, military, and personalist leaders engage in
horizontal reshuffles at similar overall rates.
Finally, maintaining credible power-sharing with ministers in dominant party regimes
should produce more distinct temporal patterns of dismissals and horizontal reshuffles. I
expect dominant party leaders to engage in major cabinet reshuffles predominantly following
elections. Magaloni (2006) argues that elections in dominant party autocracies establish
regular mechanisms of power-sharing among party elites. They also encourage party unity
by providing public signals of regime strength, provide the leader with information on regime
supporters and opponents, and encourage the opposition to operate within the existing set
of institutions rather than seeking change through violent means (Magaloni, 2006, pp. 8–9).
Regularity in cabinet turnover is important for the credibility of power-sharing as it mitigates
claims that the leader is arbitrarily dismissing ministers to undermine their authority. By
dismissing and horizontally reshuffling ministers at regular intervals, dominant party leaders
establish norms of turnover that allow them to reward a new group of party elites with cabinet
13
appointments while also minimizing impressions that power-sharing commitments have been
breached. Furthermore, in party regimes where ministers must be selected from members of
the legislature, seats can be lost in free or manipulated elections, partially reducing the need
for overt dismissals.
Many of Africa’s personalist regimes also hold elections, but the lesser importance of
credible power-sharing results in more arbitrary patterns of minister reshuffles in both elec-
tion and non-election years. As in Hypothesis 1, the extent to which military leaders increase
dismissals and horizontal reshuffles following elections depends upon the power-sharing con-
straints they face vis-á-vis civilian ministers. If military leaders are dependent upon power-
sharing with civilian ministers for the performance of and support for the regime, they will
engage in larger numbers of dismissals and horizontal reshuffles following elections. However,
if military leaders are less dependent upon civilian ministers, we will see relatively smaller
increases in dismissals and horizontal reshuffles following elections. This leads to Hypothesis
3.
Hypothesis 3: Dominant party leaders increase dismissals and horizontal reshuf-
fles to a greater extent following elections than personalist or military leaders.
Data and methods
To test these hypotheses, I collected data on the composition of cabinets for 94 leaders
in 37 African countries from 1976 to 2010 using volumes of Africa South of the Sahara
(Europa Publications Limited, 1975–2010).8 The unit of analysis is the leader-year, with
leaders identified using the Archigos data (Goemans, Gleditsch, & Chiozza, 2009).9 For each
leader-year in the sample, I code the names of cabinet ministers and the portfolios they
held. This includes all individuals listed as cabinet members by Africa South of the Sahara,
with the exception of the leader.10 Taking the leader-year as the unit of analysis means that
cabinet changes occurring because of leadership changes are excluded from analyses. Cabinet
14
instability caused by leader turnover is consequential for governance, particularly given the
prevalence of coups in Africa, but it does not speak to the constraining role of dominant
party institutions. Therefore, the hypotheses are directed only at dismissals and horizontal
reshuffles that occur within the tenure of leaders. A complete list of leaders, leader-years,
and regime type codings is included in the Supplemental Appendix.
Dependent variables
The first dependent variable measures the number of ministers who leave the cabinet in each
leader-year. The coding of this variable does not distinguish between minister dismissals,
deaths in office, or voluntary resignations because of limited data on the specific conditions
surrounding minister exits. While this only provides a proxy of minister dismissals, there are
four primary reasons to believe that this coding does not unduly bias the results in favor of
the hypotheses outlined above. First, minister deaths are likely to be randomly distributed
across dominant party, personalist, and military regimes. Second, there are few reasons to
expect more voluntary resignations in either dominant party, military, or personalist regimes.
Personalist regimes with small winning coalitions provide ministers with strong incentives
to remain loyal to the leader (Bueno de Mesquita et al., 2003), even though personalist
leaders need not remain loyal to their ministers. In dominant party regimes, the dominant
strategy of ministers, including those from rival factions, is to remain in office (Geddes,
2003). While the theoretical logic is more ambiguous for ministers in military regimes, there
are few reasons to expect higher rates of voluntary resignations compared with dominant
party or personalist regimes. Third, voluntary resignations often occur when ministers defect
to the opposition and seek to challenge candidates from the incumbent regime in legislative
or executive elections. This requires multiparty competition that is not limited to a single
authoritarian regime type. Fourth, voluntary resignations often occur because ministers are
unsatisfied with the level of power-sharing or to preempt dismissals or worse from the leader.
Dickie and Rake (1973) describe such a situation near the beginning of Hastings Banda’s

tenure in Malawi, stating that “His determination to go his own way cost him dearly. He lost
much needed talent when seven ministers went into exile after charges of plotting” (Dickie
& Rake, 1973, p. 259). This suggests that many voluntary resignations are the outcome of
failed power-sharing that my theory seeks to highlight. Therefore, the number of ministers
exiting the cabinet each year represents a reasonable proxy of minister dismissals.
The second dependent variable measures the number of ministers shuffled horizontally to
new ministerial portfolios each year. For example, I code Zimbabwe’s Emmerson Mnangagwa
as being horizontally reshuffled in 2009 when he left his previous post as Minister of Rural
Housing and Amenities to be reappointed as Minister of Defense. Horizontal reshuffles are
expected to reduce ministerial moral hazard without severely breaching power-sharing com-
mitments. Additional information on the coding of both minister dismissals and horizontal
reshuffles is provided in the Supplemental Appendix.
Independent variables
The main model specifications contain two variables of interest. The first is authoritarian
regime type. Following the coding of Geddes et al. (2014), I include dummy variables for
dominant party regimes and military regimes, leaving personalist regimes as the reference
category. In addition to dominant party, military, and personalist regimes, Geddes, Wright,
and Frantz also code hybrids of these pure types. I follow their convention of coding hybrid
regimes as the first regime type listed in the main analyses. Thus, party-personalist or party-
military hybrids are coded as dominant party regimes. However, I also estimate additional
models disaggregating hybrid regimes which are discussed below.
The second independent variable of interest is an indicator of whether or not an executive
or legislative election was held before the cabinet measurement in year t. This requires
special attention as the month in which cabinet composition is recorded by Africa South of
the Sahara varies by country, leader, and year. The variable Election takes a value of one if
there was an executive election, legislative election, or both after the cabinet measurement
16
at time t−1 but before the cabinet measurement at time t. Data on elections come from the
NELDA dataset (Hyde & Marinov, 2012). Elections are expected to induce cabinet changes
in authoritarian regimes just as they do in democracies, even if they are driven by different
motivations. However, increases in dismissals and horizontal reshuffles following elections
are expected to be greater in dominant party regimes where power-sharing commitments
discourage arbitrary reshuffles in non-election years. Elections occur in 20% of dominant
party leader-years, 20% of personalist leader-years, and 11% of military leader-years in the
sample.
Controls
I control for a variety of factors that may also influence cabinet instability. First, a leader’s
ability to co-opt clients is influenced by access to resource rents (Arriola, 2009; Smith, 2005).
Leaders with access to resource rents can more easily buy the support of political opponents,
perhaps reducing the need for credible power-sharing commitments and producing greater
cabinet instability. I control for access to resource rents using data on total resource rents
as a percentage of GDP from the World Bank’s World Development Indicators.11 Because
of missing data, the variable Resource Rents is coded 1 if the median of available data on
total resource rents for a particular country is greater than the median total resource rents
for available observations across all countries and 0 for all other leader-years. Similarly, I
also control for Ln(GDP per Capita) and GDP Growth as additional measures of the resource
constraints faced by leaders.
Second, cabinet instability is common following failed coup attempts as leaders seek to
purge coup supporters and critics from the regime. Cameroon’s Paul Biya, while initially
retaining most of former President Ahmadou Ahidjo’s cabinet, shuffled ministers extensively
after uncovering a coup plot in 1983 hatched by Ahidjo, Maj. Ibrahim Oumharou, and Capt.
Ahmadou Saleh and again after an actual coup attempt by Ahidjo and Saleh materialized
in 1984. The dismissals targeted Ahidjo allies, particularly ministers from Ahidjo’s base in
17
Cameroon’s North and Extreme North provinces. In total, Biya dismissed 10 ministers from
the North and Extreme North provinces following the failed coup attempt. The variable
Coup Attempt represents an indicator of whether a failed coup attempt took place after the
cabinet measurement at time t − 1 but before the cabinet measurement at time t, and is
coded using data from Powell and Thyne (2011).
Third, scholars have stressed the importance of ethnic balancing within African cabi-
nets. As Francois et al. (2015b) show, cabinet appointments are allocated proportionately
to ethnic group size in African states. For example, Kenneth Kaunda carefully balanced his
cabinet by appointing individuals roughly in proportion to their group’s share of the Zam-
bian population (Posner, 2005).12 However, this ethnic balancing is argued to be a source
of instability. Ethnically diverse cabinets may increase cabinet instability by producing dis-
trust between leaders and ministers from rival ethnic groups. Roessler (2011) argues that
reciprocal maneuvering of leaders and ethnic elites, both trying to consolidate their positions
within the regime, undermines power-sharing commitments and results in rival ethnic elites
being excluded from the regime. Additionally, ethnic diversity provides a greater number of
possible minimal winning coalitions, giving leaders the ability to marginalize certain groups
and form an alternative coalition (Posner, 2005). I include the variable Senior Partners
from Version 3 of the Ethnic Power Relations dataset (Wimmer, Cederman, & Min, 2009)
to measure the extent of ethnic power-sharing at high levels within the regime. This vari-
able captures the extent of formal or informal power sharing in senior positions within the
executive and is measured as the percentage of the population represented by coethnics in
senior positions.
Fourth, I account for the effect of leader tenure on cabinet instability. Scholars of par-
liamentary democracies theorize that leaders face adverse selection problems when making
cabinet appointments (Huber & Martinez-Gallardo, 2008). After imperfect appointments
are made, leaders observe the true abilities of their appointees and shuffle them to portfolios
that better suit their skill set or remove them from the cabinet entirely. Although authoritar-
18
ian leaders are likely to have different minister selection criteria (see Quiroz Flores & Smith,
2011), selection problems may still produce instability early in the tenure of leaders. Also,
the hazard of losing office declines over time for authoritarian leaders (Bueno de Mesquita
et al., 2003; Bienen & van de Walle, 1989; Svolik, 2012), which can produce more frequent
reshuffles early in the tenure of leaders as they seek to prevent ministers from capitalizing on
the initial weakness of their grasp on power. I control for duration dependence in a flexible
way by including a cubic polynomial of leader tenure in all models (Carter & Signorino,
2010).13
Finally, because the dependent variable does not distinguish between dismissals and
voluntary resignations, I control for the presence of multiparty elections in the legislature
using the Lexical Index of Electoral Democracy (LIED) dataset (Skaaning, Gerring, & Bar-
tusevičius, 2015). This variable addresses the possibility that ministers are more willing
to voluntarily exit the cabinet when they can legally challenge the incumbent through an
opposition party.
Estimation method
Since both dependent variables represent discrete numbers of ministers dismissed or hori-
zontally reshuffled each year, count models provide an appropriate estimation framework. I
choose the more flexible negative binomial distribution over the Poisson as both dependent
variables show signs of overdispersion. The natural logarithm of cabinet size is included as
an offset variable in all models to account for differing levels of exposure to dismissals and
horizontal reshuffles across leader-years.14 For instance, 41 ministers faced the possibility of
dismissal or horizontal reshuffle in Laurent Gbagbo’s 2006 cabinet in Côte d’Ivoire, but only
14 ministers faced these actions in Moussa Traore’s 1980 cabinet in Mali.
Additionally, the panel structure of the data presents the potential for leader-specific ef-
fects, non-constant variance across leaders, and autocorrelation within the tenure of leaders.
Fixed effects are commonly used to control for unit-specific effects in panel data settings;
19
however, the lack of variation in the regime type variables within the tenure of individual
leaders prevents their use. Non-constant error variance and autocorrelation are addressed us-
ing standard errors clustered by leader. Further robustness checks allowing for leader-specific
random effects and modeling first order autocorrelation directly through the generalized es-
timating equations (GEE) framework are discussed below and presented in Tables A3 and
A4 in the Supplemental Appendix. These alternative modeling choices do not alter the main
findings.
Results
Table 1 reports the results of the negative binomial regressions. Models 1 and 2 estimate
the effects of regime type and elections on minister dismissals. In Model 1, the effects of
the regime type and election variables are modeled independently. As expected, the Party
Regime coefficient is negative and significant, indicating that dominant party leaders dismiss
fewer ministers than personalist leaders. The Military Regime coefficient is negative but
only significant at the 10% level. Additionally, an F-test of the equality of the Party Regime
and Military Regime coefficients reveals no significant difference (F = 1.09, p = 0.30).
Therefore, dominant party leaders dismiss fewer ministers than personalist leaders, but the
results for military leaders are ambiguous. Finally, the Election coefficient is positive and
significant, indicating that minister dismissals increase following elections.
Model 2 tests Hypothesis 3 by interacting the Party Regime and Military Regime
variables with Election to determine whether post-election increases in dismissals differ
across regime types. The Party Regime coefficient remains negative and significant, showing
that dominant party leaders dismiss fewer ministers in non-election years than personalist
leaders. The Military Regime coefficient is negative but not significant at any conventional
level, suggesting no differences in non-election year shuffles by military and personalist regime
leaders. The positive and significant coefficient for Election shows that personalist leaders

increase dismissals following elections. Consistent with Hypothesis 3, however, the Party
X Election coefficient is positive and significant, which demonstrates that dominant party
leaders increase dismissals following elections to a greater extent than personalist leaders.
The Military X Election coefficient is negative but not significant at any conventional
level, indicating that post-election dismissal increases by military and personalist leaders
are similar. As in Model 1, F-tests fail to reject the hypothesis that dominant party and
military regimes have the same effect in non-election years (F = 2.35, p = 0.13) or that
elections have the same effect in dominant party and military regimes (F = 2.39, p = 0.12).
Taken together, these results show that the hypothesized differences between dominant party
and personalist leaders are supported, but the differences between military leaders and either
dominant party or personalist leaders are ambiguous.
Models 3 and 4 in Table 1 estimate the effects of regime type and elections on horizon-
tal reshuffles. The coefficients for Party Regime and Military Regime are not significant
in Model 3. This provides support for Hypothesis 2 which predicts similar overall rates
of horizontal reshuffles by dominant party, personalist, and military leaders. As expected,
the Election coefficient is positive and significant for horizontal shuffles. Model 4 interacts
Party Regime and Military Regime with Election to test whether horizontal reshuffles
differ across regime types in election and non-election years. The Election coefficient, now
representing the effect of elections in personalist regimes, is reduced in magnitude, but re-
mains positive and significant. The coefficients for the Party X Election and Military
X Election terms are positive and significant, showing that the post-election increases in
horizontal reshuffles of dominant party and military leaders are greater than those of per-
sonalist leaders. However, an F-test shows that the effects of elections in dominant party
regimes and military regimes do not differ from each other (F = 0.16, p = 0.69). Thus, while
the dismissal behavior of military leaders is ambiguous, the horizontal reshuffles of military
leaders resemble those of dominant party leaders.
Since the substantive effects of the negative binomial coefficients are difficult to interpret,

Figure 1: Predicted dismissals and horizontal reshuffles with 95% confidence intervals.Predictions calculated using Models 2 and 4 in Table 1 with all variables set to their respectiveregime type means with the exception of Multiparty and Resource Rents which are set to1 and Coup Attempt which is set to 0 for all regime type categories.
I present the results graphically in two ways. First, Figure 1 plots the predicted number of
minister dismissals and horizontal reshuffles for military, party, and personalist leaders during
election and non-election years. The predictions are calculated holding the control variables
at their sample means for the particular regime type, with the exception of Multiparty
which takes a value of 1 for all regime categories and Coup Attempt and Resource Rents
which take a value of 0 for all regime categories. The plot of predicted dismissals in the
top panel of Figure 1 follows the same general patterns shown in Table 1. Dominant party
leaders are predicted to dismiss 3.2 ministers in non-election years compared to 6.3 ministers
for personalist leaders. In election years, dominant party leaders are predicted to dismiss
7 ministers compared to 8.8 ministers for personalist leaders. Therefore, dominant party
23
leaders clearly have more stable cabinets in non-election years and tend to refrain from
larger numbers of dismissals until after elections. Moreover, as Table 1 demonstrates, the
differences between military regimes and either party or personalist regimes are less clear in
Figure 1. Military leaders are predicted to dismiss 4.4 ministers in non-election years and 5.3
ministers in election years, but the wide confidence intervals for the predictions make them
statistically indistinguishable from the predictions for either party or personalist leaders.15

Figure 2: Average marginal effects with 95% confidence intervals calculated using Models2 and 4 from Table 1.
Second, I also present the average marginal effects of each variable in Figure 2 following
the recommendation of Hanmer and Kalkan (2013). Average marginal effects (AMEs) are
calculated by holding each additional covariate at its observed value rather than the values
chosen to calculate the predicted counts in Figure 1. This means that no AMEs are calculated
for the Party X Election or Military X Election interactions. Figure 2 shows that the
AME of Party Regime is negative and significant for dismissals. This provides additional
support for Hypothesis 1. The AME of Military Regime is also negative and significant for
dismissals, providing some support for the hypothesis that the dependence of military leaders
on civilian ministers for regime performance and popular support produces greater power-
sharing constraints than are found in personalist regimes.16 As the right panel of Figure 2
shows, the AMEs for Party Regime and Military Regime are both indistinguishable from
24
zero for horizontal reshuffles, consistent with Hypothesis 2.
Estimates for the control variables also demonstrate interesting dynamics, particularly
for the Multiparty and Senior Partners variables. The Multiparty coefficient is negative
and significant in all model specifications for dismissals and horizontal reshuffles, as are the
average marginal effects displayed in Figure 2. Multiparty competition, even in Africa’s
authoritarian regimes, has thus brought greater cabinet stability. The coefficient for Senior
Partners are negative and significant for dismissals and positive and significant for horizontal
reshuffles, as are the average marginal effects displayed in Figure 2. This shows that greater
ethnic diversity in the executive branch reduces the number of minister dismissals, but
increases the rate at which leaders horizontally reshuffle ministers. These results provide an
interesting extension of research by Roessler (2011) who finds that commitment problems
between African leaders and rival ethnic groups results in exclusion from the regime. While
this may be the case broadly, diversity among senior regime elites appears to restrict the
leader’s ability to dismiss ministers. However, following Roessler’s argument, mutual distrust
between the leader and rival ethnic elites within the cabinet may result in more horizontal
reshuffles as the leader attempts to maintain a diverse coalition while still attempting to
undermine the authority of non-coethnic elites.
Robustness checks
I estimate several additional models to examine the robustness of the results to a number
of different modeling and specification choices. One concern is that the estimates in Table
1 are being driven by unobserved leader-specific effects and not differences in constraints
across regime types. Although leader fixed effects cannot be estimated because regime type
does not vary across the tenure of leaders, I adopt three alternative approaches to assess the
impact of individual leaders on the main findings.
First, I split the data into dominant party, personalist, and military samples and estimate
the effect of elections in each sample while including leader fixed effects. If the estimates
25
in Table 1 are not biased by leader specific effects, the Election coefficient in models of
dismissals should be largest in the dominant party sample. As Table 2 shows, the Election
coefficient is approximately three times larger in the dominant party sample than in the
personalist sample. Similar to the results in Table 1, the Election coefficient for the military
regime sample in Model 3 is positive but is only significant at the 10% level. These findings
suggest that the estimates of post-election dismissals for dominant party, personalist, and
military leaders are not biased by leader specific effects. The split sample estimate for
horizontal reshuffles in Table 2 are also consistent with the findings in Table 1. The Election
coefficient is larger in the dominant party sample than the personalist sample, and is largest
in the military regime sample. Additionally, the split sample estimates reveal differences in
the effects of control variables not modeled in Table 1. This is particularly the case with
the Coup Attempt variable, which is positive and significant only for the personalist leaders.
This finding provides indirect evidence of the power-sharing constraints faced by dominant
party and military leaders.
Second, I estimate negative binomial models with leader random effects. The estimates,
presented in Table A3 of the Supplemental Appendix, remain very similar to those in Table
1.. Third, I examine the sensitivity of the findings of Models 2 and 4 in Table 1 to the
exclusion of single leaders and countries from the dataset. Figures A2 and A3 plot the
density of coefficient estimates and p-values obtained for the Party Regime and Party x
Election coefficients in Table 1 Model 2 when dropping each individual leader and country
from the dataset and reestimating the model. The results remain consistent across the
different subsets of leaders and countries.
Another concern given the panel structure of the data is autocorrelation. I address
this through the generalized estimating equations (GEE) framework (see Hilbe, 2011). The
estimates from GEE models with an AR(1) working correlation structure are presented
in Table A4 Supplemental Appendix. Coefficients for the regime type variables and their
interactions with elections remain very similar to those in Table 1.

I also examine the robustness of the regime type coding in two ways. First, the analyses
in Table 1 follow the approach of Geddes et al. (2014) by coding party–personalist or party–
military hybrids as dominant party regimes.17 Importantly, this decision should bias the
results against the hypotheses above since Geddes’s (2003, p. 73) coding gives less weight to
the party coding where: 1) party membership is highly urban with little grassroots organi-
zation; 2) the politburo serves as a rubber stamp for the leader and the leader plays a large
role in the selection of its members; 3) the government is dominated by one particular group
in heterogeneous societies; and 4) nepotism is common in high offices. As expected, the
estimates in Table A5 of the Supplemental Appendix show that the Pure Party and Pure
Party X Election coefficients increase in magnitude in the dismissal models after including
27
an additional hybrid party variable. However, the coefficients for Hybrid Party and Hybrid
Party X Election are not significant. This suggests that the organization, authority, and
make-up of dominant party regimes is critical for the ability of the party to constrain the
leader.18 Second, I recode the Party Regime variable to distinguish between leaders who
founded the party regime and those who became the leader of a preexisting party regime. If
the non-founding leaders of party regimes are similarly or more constrained than founding
party leaders, the theoretical argument above gains additional support. The estimates in
Table A10 show that both founding and non-founding party regime leaders follow the pat-
tern of Party Regime in Table 1; however, the coefficients for the non-founding party leader
and its interaction with elections are larger than those for founding party leaders. This also
eases concerns that the regime type coding is endogenous to cabinet reshuffles.
Next, the main findings may be driven by dominant party regimes being more democratic
than military or personalist regimes. For example, Botswana is coded as a dominant party
dictatorship, has relatively little cabinet instability, and is considered democratic by most
African politics scholars. While the estimates in Table 1 control for multiparty regimes, I
also control for Polity 2 scores (Marshall, Gurr, & Jaggers, 2013) in Table A6. Controlling
for the level of democracy produces coefficients that are nearly identical to those in Table
1. This increases confidence that the results are not merely due to presence of countries like
Botswana or Tanzania that score high on the Polity index, have relatively stable cabinets,
but are labeled as dominant party dictatorships by Geddes et al. (2014). Similarly, Roberts
(2015) shows, the presidential or parliamentary structure of authoritarian regimes is conse-
quential for their overall durability and cabinet stability. While most African autocracies in
the sample are presidential systems, countries such as Botswana and Ethiopia under Meles
Zenawi have parliamentary systems. Table A7 shows that parliamentary systems do reduce
both dismissals and horizontal reshuffles of cabinet ministers. However, estimates for the
variables of interest remain very similar.
Finally, I estimate models using a restricted sample of cabinet ministers that excludes
28
junior, assistant, and deputy ministers following the coding of Arriola (2009) and conduct
an extreme bounds analysis on the coefficients of Models 2 and 4 of Table 1. The estimates
presented in Table A8 show that the main findings are not driven by my more inclusive
definition of the cabinet. The extreme bounds analysis (Table A12 and Figure A4 shows
that the findings for the variables of interest are robust to alternative model specifications.
Conclusion
This article addresses gaps in the research on patronage politics and authoritarian institu-
tions to explain variation in cabinet instability between dominant party, personalist, and
military dictatorships in Africa. Although the literature on patronage politics thoroughly
discusses the motivations driving African autocrats to frequently reshuffle their cabinets,
it fails to explain the constraining role of dominant party regimes. The literature on au-
thoritarian institutions, while describing the ability of dominant party regimes to establish
credible power-sharing between the leader and party elites, is reliant on studies of leader
and regime tenure for empirical support. This study breaks new ground by examining how
dominant party regimes constrain the ability of leaders to reshuffle cabinets, thus providing
a more direct look at elite power-sharing at the highest level.
I show that dominant party regimes influence the extent and timing of minister dismissals
in African dictatorships. Dominant party leaders dismiss far fewer ministers than do per-
sonalist leaders. Also, dominant party leaders tend to engage in large numbers of dismissals
and horizontal reshuffles only after elections to establish regular patterns of cabinet change
and increase the credibility of power-sharing. Conversely, personalist leaders face fewer con-
straints and engage in more arbitrary patterns of dismissals and horizontal reshuffles that
vary less between election and non-election years. Patterns of dismissals in Africa’s military
regimes exhibit greater variation and are indistinguishable from either personalist or domi-
nant party regimes. Military leaders do appear to engage in greater numbers of horizontal
29
reshuffles following elections, but this should be interpreted with caution as there are few
elections in military regimes.
These findings broadly support the literature on authoritarian power-sharing, but also
add important nuance. I demonstrate that dominant party leaders need not relinquish con-
trol over cabinet appointments and dismissals to the party for credible power-sharing to take
place. Instead, the structure of dominant party regimes constrains the ability of leaders to
shuffle ministers arbitrarily. I also explain that power-sharing dynamics in military regimes
become more complex as civilians are appointed to senior positions within the regime. Addi-
tionally, I show that explanations of elite shuffles rooted in the patronage politics literature
are primarily applicable to personalist regimes. While future work is needed to assess the
generalizability of these findings beyond sub Saharan Africa, the theory is sufficiently general
to be applied to other regions.
Finally, this research highlights two particularly important areas of future research. First,
more research is necessary to understand how regime type influences the risk of dismissal or
reappointment for individual ministers and how individual minister characteristics influence
such risks. Recent work has begun to examine the influence of gender on the tenure of
individual ministers (Arriola & Johnson, 2014; Escobar-Lemmon & Taylor-Robinson, 2014;
Krook & O’Brien, 2012), but more work is needed on the effects of ethnic identity and port-
folio prestige on minister tenure. For instance, further investigation of the divergent effects
of ethnic diversity in the executive on dismissals and horizontal reshuffles can provide an
important addition to Roessler’s (2011) work on ethnic exclusion in African states. Second,
future work can build on recent studies of party system development in Africa LeBas, 2011;
Riedl, 2014, e.g., to better understand the conditions under which ministers and other elites
defect to build opposition parties or join existing opposition parties.

1Francois et al. (2015b, 2015a) are exceptions.2Shuffling ministers is also costly in terms of bureaucratic capacity and efficiency. Fre-
quently shuffling ministers undermines ministers’ ability to implement government policies,
thus undermining state capacity (Besley & Perrson, 2010). Instability in office also discour-
ages the formation of ties and communication among bureaucrats, which is detrimental to
policy implementation (Rauch & Evans, 2000). This is not to say that autocrats desire an
effective bureaucracy. Quiroz Flores and Smith (2011) explain that autocrats prefer bu-
reaucrats that are loyal but mediocre in their performance. Nevertheless, rapidly shuffling
ministers creates a difficult environment for policy implementation.3Alternatively, elite splits can also spur cabinet instability by increasing voluntary resig-
nations.4The mere existence of a political party associated with the leader does not constitute a
dominant party regime according Geddes (2003). Compaoré, Jammeh, and other personalist
regime leaders establish political parties. However, the lack of party control over political
appointments and policy results in these regimes being classified as personalist.5The RSP helped Compaoré maintain power for nearly three decades, but were also
instrumental in his demise (see Chouli, 2015).6Geddes (2006) makes a similar argument about the development of political parties in
authoritarian regimes, arguing that they serve to reduce reliance on the military for survival.7Each empirical model includes ln(cabinet size) as an offset variable. The use of an offset
variable accounts for the fact that 10 dismissals in a 20 minister cabinet is different from 10
dismissals in a 40 minister cabinet.8Cases were selected based upon their coding as authoritarian by Geddes et al. (2014),
their inclusion in Arriola’s (2009) study of cabinet size, and their status as independent
countries by 1990. Geddes et al. (2014) code authoritarian regimes with a population of
greater than 1 million in 2009. The only exceptions to these rules are Somalia and Swaziland.
31
Data was not collected for Somalia because of its coding as a warlord regime from 1991–2010.
Data was not included for Swaziland because it is the only monarchical regime between 1976
and 2010.9Leaders listed in Archigos are cross-checked with those listed in Africa South of the
Sahara. In total, there are 947 leader-years in the dataset. The mean tenure of the leaders
is 11.9 years.10Arriola’s (2009) cabinet coding only includes ministers of full ministerial rank, excluding
assistant ministers, deputy ministers, junior ministers, and the like. Arriola bases this deci-
sion on the inconsistent reporting of such cabinet members across countries in Africa South
of the Sahara. Although this makes sense given Arriola’s focus on cabinet size, I find the
exclusion of lower ranking ministers to be unwarranted when studying minister dismissals
and horizontal reshuffles. Within the tenure of individual leaders, Africa South of the Sahara
provides consistent coverage of cabinets. When ministers of less than full ministerial rank are
listed, they appear consistently throughout the tenure of the particular leader. Furthermore,
all empirical analyses control for cabinet size and robustness checks conducted with only full
ministers (Table A8 of the Supplemental Appendix) produce the same substantive results.11This variable represents a combination of rents from forestry, minerals, and oil.12Despite this ethnic balancing, Posner (2005) notes that Bemba’s occupied a dispropor-
tionate share of prestigious cabinet portfolios such as Defense, Home Affairs, Foreign Affairs,
and Finance.13Models controlling for a cubic polynomial of regime tenure are presented in Table A11.
The findings remain the same.14The offset variable coefficient, ln(cabinet size), is assumed to be 1.15Confidence intervals are particularly wide for military leaders’ election year dismissals
since their are only 10 elections in military regimes in the dataset.16Importantly, the negative binomial coefficients and AMEs are testing different hypothe-
ses. The former test whether the effect of the independent variable differs from zero while
32
the latter test whether the average of all marginal effects for a variable when all covariates
are held at their observed values differs from zero. As Greene (2009) states, “Arguably, the
inference should be based about θk (the coefficient), not δk (the AME), since in the latter
case, one is testing a hypothesis about all the coefficients, not just the one of interest” (p.
487).17Of 431 leader-years coded dominant party in Table 1, 84 are party hybrids. For instance,
Gabon is coded as a party–personalist regime under the rule of Omar Bongo.18Alternatively, the small number of hybrid party regimes may explain the imprecise esti-
mates for Hybrid Party and Hybrid Party X Election coefficients. Models distinguishing
between party-personalist and party-military hybrids also yield insignificant coefficients.

Supplemental Appendix for Dominant party rule, elections, andcabinet instability in African autocracies
(Not for publication)
This document contains additional information on data coding as well as additional
robustness checks that are not included in the main text.
Coding of cabinet instability
The data on cabinets is taken from yearly volumes of Europa Publications Limited (1975–
2010). This presents several challenges for empirical analyses. First, Europa records the
composition of cabinets once a year, often at irregular intervals. For instance, the composi-
tion of Kenya’s cabinet may be recorded in May during year t and in September during year
t+ 1. My own inspection of the data indicates that cabinet composition is usually measured
after events such as elections or coups. However, reshuffles can happen multiple times each
year. This is something that my coding of cabinet instability cannot capture.
Similarly, the irregular measuring of cabinet composition introduces assumptions into the
coding of dismissals and horizontal reshuffles. A minister is coded as having been dismissed
in year t if they were a member of the cabinet in year t−1 but are not recorded as part of the
cabinet in year t. This coding does not allow for the possibility that the minister actually
left the cabinet in the previous year, creating the potential for measurement error. The
same problem occurs with the coding of horizontal reshuffles. A minister is coded as being
horizontally reshuffled in year t if they are in charge of a different portfolio in year t than
they were in year t − 1. Therefore, the precise timing of minister dismissals and horizontal
reshuffles is not known.
The cabinet composition data also present challenges for the measurement of independent
variables representing discrete events such as elections and coup attempts. Fortunately, both
NELDA and Powell and Thyne (2011) code the dates that elections and coups take place.
This information is used when coding these variables to ensure that the month in which an
40
election or coup took place comes before, or is equal to, the month in which the cabinet was
recorded. For example, if the cabinet was recorded in March of 1995 and a coup attempt
took place in October of 1995, a coup attempt would be recorded in 1996. If the cabinet
was recorded in August 2000 and an election occurred in July of 2000, then 2000 would be
coded as an election year because the election came before the cabinet measurement.
Technical details and code files for the coding of the raw minister data are available from
the author upon request.
