Options:
1 Drawing on savings2 Selling assets3 Borrowing from the extended family4 Children as insurance asset:
School de-enrolment (→ economizing educationalexpenditures)Child labour (→ generating income; replacing family membersin household production)

Ex post risk coping strategy:Income shock ⇒ consumption smoothing

Ex ante risk coping strategy:Income risk ⇒ precautionary savings
child time allocation is affected even if shocks do not realizeFitzsimons (2007), Kazianga (2012)

Significant long-term costs:
Child labour is associated with
worsened health (O’Donnell et al., 2005)lower educational attainment (Beegle et al., 2008, Zabaleta,2011)lower cognitive achievements (Akabayashi & Psacharopoulos,1999, Heady, 2003)
Withdrawals from school reduce probability to return to school(de Janvry et al., 2006)
⇒ lower human capital accumulation⇒ lower future earnings, productivity, well-being;
perpetuated poverty

Literature
Formal health insurance ⇒ Informal risk coping strategies:
Dekker and Wilms (2009):
insured households sell assets less frequently and borrow lessmoney to finance medical treatment (Uganda)
Wagstaff and Pradhan (2005):
insured households have higher educational expenditures(Vietnam)
Guarcello et al. (2010):
children of insured households are less likely to work and morelikely to go to school (Guatemala)

Community-based health insurance in Rwanda
History:1999: pilot test in 3 districts, provided by so-called Mutuellesfrom 2003 on: progressively scaled up to a national systempopulation coverage rate: 7% (2003), 44% (2005), 73%(2006), 91% (2010)
Affiliation conditions (time of survey):enrolment at household levelannual premium: 2,500-11,500 RWF per household(3.80-17.40 USD)co-payments: 100-150 RWF (0.15-0.22 USD) per visit athealth center; 10% of hospital fee at district hospital
Benefit Packages:Minimum Package: all services provided at local health centerComplementary Package: limited services provided at districthospitals

Data
Data set:Household Living Conditions Survey (EICV2) 2005/06cross-sectional, nationally representativesocio-economic data of 6,900 households and 34,785individualscommunity-level data for 440 communities (only for rural partof Rwanda)
Final sample:restriction on rural regions of Rwandaexclusion of households insured in health insurance schemesother than Mutuelles (RAMA, MMI, private schemes)households with children from 7-15 yearshousehold head older than 15 years
⇒ 5,811 children living in 3,154 households⇒ 43,4 % of households insured by Mutuelles

2 Education Gap:Education Gap =max{0, Expected Education−Actual Education}

Hijk : Hours worked or Education Gap

Xijk : Child, household, community characteristics

Test of endogeneity
Two instrumental variables (IV)1 Community Mutuelle enrolment rate = Ei−Di
Ni−1
Ei = Number of enrolled households in communityDi = Dummy if household is enrolledNi = Total number of households in community
2 Satisfaction of household with quality of services provided atdistrict hospital (dummy)
Test on relevance and overidentifying restrictions⇒ IV validated
Test of endogeneity⇒ Mutuelle enrolment can be treated as exogenous
⇒ Simple count data regression models

Substantial impact of mutual health insurance on schoolingoutcomes:
remarkably, as Mutuelles cover only a part of total economiccost of illness:
do not compensate for lost earningsco-payments have to be effected
compared to decrease of child working time of 1 hour per week:
suggests that impact on schooling not only via time-liberatingeffect

Possible impact channels
Formal health insurance ⇒ Child labour and schooling:
1 Mutuelles protect Rwandan households efficiently againsthigh OOP payments (Lu et al., 2012, Saksena et al. 2011,Shimeles, 2010)
ex ante: reduced need to build up a buffer stockex post: facilitated consumption smoothing
2 Mutuelle members use modern health care more likely(Lu et al., 2012, Saksena et al. 2011, Shimeles, 2010)
faster recovery / better overall health statusless income losses and treatment costsless time absent in school, better learning performance

Policy implications
Formal health insurance:
Indirect benefits so far unrecognized:
crowding out of inefficient risk coping strategies (child labourand school de-enrolment)higher human capital accumulationshould be taken into account in cost-efficiency analyses of suchpolicy interventions
Useful and necessary complement to explicit child labourcountermeasures (bans, compulsory schooling):
eliminating child labour without undermining household’sability to cope with risk

Limitations and Outlook
Cross-sectional data set:Unobserved heterogeneity and biasing effect on estimatescannot be definitely ruled out
however, solid evidence on robustness of results by using twodifferent evaluation methods
Impossible to disentangle impact channels of healthinsurance (ex post, ex ante, health-related effects)
might be important to choose optimal policy intervention(e.g. if ex post consumption smoothing is main driver of results→ could also be reached with provision of credits)
