    This paper presents for Romanian firms the results of the first survey on price-setting patternsamong the New Member States of the EU. Diverging from Inflation Persistence Network(IPN) findings, generally small firms perceive higher competitive pressure and adopt themarket price, using a state-dependent rule, while lower perceived competition is consistentwith medium and large firms using mark-up pricing. Prices are reviewed and changed moreoften than for EMU firms and are more flexible than wages. Similar to IPN evidence,contracts are the main sources of price stickiness. The survey suggests full price transmissionof large unanticipated financial shocks. Copyrightr 2009 John Wiley & Sons, Ltd.

    1. INTRODUCTION

    The empirical evidence gathered to support New

    Keynesian microfounded macroeconomic models

    prominently those involving some type of price

    stickinesshas been growing steadily in the recent

    periods, looking both on aggregate and micro/firm-level data. Within this line of research, an increasing

    set of studies uses a survey-based approach in

    documenting various aspects of price stickiness.

    The main advantage when compared with other

    approaches1 lies in the fact that it allows for

    additional insights and permits a clear inventory

    and ranking of the causes and patterns of price

    stickiness. Initiated by Blinder (1991) for the United

    States, this class of research has spread considerably

    on account of a number of survey-based studies

    conducted within the Eurosystems Inflation

    Persistence Network (IPN).2

    However, when it comes to the New Member

    States of the European Union (NMS), microlevel

    evidence is rather scarce and, to our knowledge,

    there are no studies that use a survey-based

    approach.3 The present study fills this lacuna,

    being the first survey among local companies

    conducted for an NMS economy capturing various

    price-setting patterns and comparing them with

    results from developed economy surveys. Anothernovelty of this paper is using survey evidence to

    capture the perceived impact of interest rate and/or

    exchange rate shocks on prices and costs.

    The main findings of the paper can be

    summarized as follows: most Romanian firms

    declare to set their prices internally; nevertheless,

    they appear to be operating in a relatively high

    competition environment, more prominently in the

    case of small enterprises. In general, these are

    predominantly market price followers, in contrast

    to medium and large firms, which tend to prefer

    mark-up pricing. Most of the firms surveyed use atime-dependent price-reviewing strategy with

    state-dependent elements, the latter strategy

    alone being adopted mostly by small firms. On

    average, Romanian firms review and change prices

    more often than firms surveyed by IPN studies,

    with large firms being more active in adopting less

    rigid prices, probably due to nonbinding resource

    constraints and higher mispricing costs. Similar to

    IPN evidence, contracts in either their implicit or

    explicit forms are the main sources of price

    stickiness, with traditional theories (e.g. menu

    costs) ranking at the bottom. Survey evidence

    also suggests that wages are stickier than prices,

    with around 72% of firms changing their wagesjust once per year or less. Finally, firms generally

    admit to fully transmit into their prices the impact

    of large unanticipated financial shocks.

    Besides the general caveats of any survey-based

    analysis, when interpreting our results one should

    take into account the relatively low response rate

    (19.83%) when compared to the average of the

    IPN studies (45%4). Considering these latter

    aspects and the central banks focus on CPI

    inflation and its use of microfounded models in

    policy research and forecasting, evidence from this

    paper should be complemented by further

    investigating the disaggregated data used for CPI

    compilation.

    The paper is organized as follows. Section 2

    briefly introduces the macroeconomics background

    and survey design, while Section 3 details the

    results of the survey. Conclusions close the paper.

    2. MACROECONOMIC BACKGROUND AND

    SURVEY DESIGN

    The survey was carried out with the help of the

    National Bank of Romania (NBR) and the Public

    Policy Center (CENPO) between September and

    November, 2006. Firms were asked to refer in their

    answers to their main product/service sold in the

    course of the year 2005.

    At that juncture, the Romanian economy has

    been undergoing the transition process toward a

    fully-fledged market economy, in the context of its

    expected European Union (EU) accession.

    Compared with the Central and Eastern Europe

    (CEE) region, Romania has had a long history ofhigh and volatile inflation. However, the

    20002005 period was characterized by an almost

    continuous disinflation process, with inflation

    declining from 40 to 50% per year to below 10%

    at the end of the period mentioned. For the NBR,

    which had conducted monetary policy mainly

    through a strongly managed currency, the main

    challenge was to reconcile its newly introduced

    inflation targeting regime (since August 2005) with

    the liberalization of the capital account and the

    integration with EU financial markets. Another

    challenge to consider has been the accommodation

    of the catching-up economy, with fast expanding

    domestic demand5 fuelling external imbalances

    and inflation.

    The population from which the sample was

    drawn included all firms reporting valid balancesheets and profit reports to the fiscal authority in

    June 2005, i.e. theoretically the whole population

    of the Romanian firms. In order to avoid over-

    representing very small firms, we followed the

    approach of A lvarez and Hernando (2005) and

    Martins (2005) and chose to filter out firms with

    fewer than 10 employees. For this population,

    stratified random sampling based on relative

    number of employees was used. Firms were split

    into 114 mutually exclusive strata based on firm

    size and NACE sector. Small, medium and large

    firms were identified using cutoffs of 10, 50 and

    250 employees, respectively. Considering the fast

    and overreaching changes across the Romanian

    economy, the sector coverage is in our case

    broader than in most of the studies carried out

    within IPN, including 38 NACE sectors grouped

    into six main categories: agriculture and related

    activities (NACE 1, 2 and 5), manufacturing

    (NACE 1537), energy (NACE 40 and 41),

    constructions (NACE 45), trade, hotels and

    restaurants (NACE 5052, 55), and transport

    and communications (NACE 6064).

    The sample of 1901 firms accounted for 10% of

    the initial population in terms of employment. Out

    of these, a number of 377 firms eventually

    answered the questionnaire, thus producing

    an answer rate of 19.83%. A post-weighting

    procedure, using the number of employees as the

    benchmark measure, was applied to these firms

    answers, considering that the ex-post sample

    displayed an overrepresentation bias in favor of

    large firms.6 Throughout the paper, the reported

    results pertain to the post-weighted answers.

    The survey draws closely to those developed inthe context of the IPN, thus seeking to ensure a

    comparable basis with their results. However,

    unlike the other surveys, we test the reaction of

    firms prices and costs to potential macroeconomic

    shocks in the form of ranking-type questions

    attached to various interest rate and exchange

    rate scenarios. Otherwise indicated, firms were

    asked to consider the year 2005 as the reference

    period.

    3. SURVEY RESULTS

    3.1. Product, Market and Client Type

    When completing the questionnaire, firms were

    asked to relate all the answers to their main

    product/service, identifiable as the one that

    contributed the most to the companys turnoverin 2005. The responses indicated that the main

    product generated an average of 81% of firms

    turnover,7 with a lower contribution for the

    wholesale and retail trade sectors/large firms,

    which is consistent with the larger number of

    products these companies usually sell.

    The main market was identified by the firms as

    being the domestic one. Namely, 84% of their

    turnover was generated on average from sales in

    Romania, while approximately 14% indicated EU

    as the main market (the general case for large

    firms8 and for manufacturing and transportationfirms).

    Similar to those surveyed within the IPN9

    (Fabiani et al ., 2005), most Romanian firms

    (around 71%) have other firms as their main

    clients, while only a relatively small fraction (27%)

    count on the population as representing the main

    customer base, the latter aspect suggesting the

    relevance of the results for the price-setting

    behavior in the whole economy and not

    specifically in the more CPI inflation-relevant,

    consumer goods sector.

    3.2. Perceived Competition

    The degree of competition firms perceived is an

    important variable in the price-setting process. In

    a perfectly competitive environment there will be

    no price rigidities as firms will set their prices equal

    with marginal costs. For price rigidities to exist,

    some departures from the case of perfect

    competition should be in place, generally in the

    form of companies exercising a certain degree of

    market power. Several questions were included inthe survey in order to assess Romanian companies

    perceived degree of competition either directly or

    indirectly.

    Our conclusions are based mainly on the

    evidence obtained from the indirect questions

    because answers obtained to the direct questions

    were often contradictory. For instance, a number

    of small firms indicated that they have a high

    number of competitors and at the same time they

    enjoy a market share of close to 100%, while other

    firms that chose a very narrow identification of

    their competitor base, e.g. only local competitors,

    also indicated a low market share. A lvarez and

    Hernando (2005) point out at least three reasons

    why the answers to such questions might not

    properly proxy the degree of competition: the

    subjectivity in identifying the competitors and/orthe local market, the possibility of having fierce

    competition on some oligopolistic markets and the

    coexistence of a high number of competitors and

    high market share over some predetermined small

    area.

    Indirect questions for which answers were more

    reliable included those regarding the perceived

    elasticity of demand to a 10% price increase and

    the importance that firms attach to competitors

    prices when setting their own.

    When asked about the perceived elasticity of

    demand to a 10% price increase, 40% of firms

    estimated that the quantity sold would go down by

    more than 10%, 12% indicated a unit elasticity

    and 19% a below unit elasticity.10 The highest

    percentage of firms reporting an above unit price

    elasticity was recorded in the agricultural sector,

    while the similar measure varied inversely with the

    size of the firm.

    As further indirect evidence, competitors prices

    ranked high among factors explaining firms

    decisions to change their prices, namely third in

    the case of price increases and first in that of price

    decreases (see Table 3, Section 3.4.2). Answers to

    this question were deemed as decisive in assessing

    the degree of competition in a number of similar

    studies (e.g. A lvarez and Hernando, 2005, for

    Spain). Besides the differentiated answers for price

    decreases and increases, we also found an

    asymmetry in that competitors prices were

    ranked as more important by small and medium

    firms when compared with the large ones.

    Corroborated with answers from the previous

    question, this suggests that the degree of

    perceived competition is higher for small firmswhen compared to large ones, which is a

    distinctively different result from that reported

    by Fabiani et al. (2005) for EMU countries, where

    the degree of perceived competition varies directly

    with the size of the firm.

    One possible explanation could be that EMU

    integration has spurred higher competition for

    large firms, as cross-border expansions of business

    has become less costlyin other words national

    monopolies and oligopolies have become less

    relevant in the context of a Single Market.

    A second point is that the challenges of European

    integration and the single currency may have

    stimulated smaller firms in the EMU to adopt

    more client-oriented strategies, such as product

    customization and niche specialization, thus being

    better positioned to shrug off direct competition.Finally, the difference between Romania and IPN

    countries may be artificially induced by the fact

    that in some of the IPN surveys the starting cutoff

    for firm selection is higher than ours.

    In general, a higher autonomy in price setting is

    associated with the presence of price rigidities. In

    the Romanian case, despite the high perceived

    competition, 63% of firms declared to have full

    autonomy in setting the price of their main

    product, while main customers setting directly the

    prices of their suppliers ranked second with a

    percentage of 29% of all firms. The latter

    proportion is significantly higher than that

    obtained in similar studies for Portugal and

    Spain (A lvarez and Hernando, 2005, for Spain;

    Martins, 2005, for Portugal) and it is mainly due

    to sectors such as agriculture and transport and

    communications. It is also more relevant for larger

    rather than smaller firms, which is consistent with

    the former having a higher relative proportion of

    corporate customersforeign firms and other

    large Romanian companieswith which they

    nurture a stable relationship.

    3.3. Price-Setting Behavior

    3.3.1 The how in the pricing decision

    The first four questions on pricing behavior

    aimed to capture the main techniques used in the

    pricing decision. As mentioned before, firms which

    have authority over this decision represent 63%

    of the sample. Among these, most firms prefer

    either setting a markup over costs (for 43% of

    these firms) or adopting the market price (for

    roughly 50% of this subsample). It is worth

    mentioning that compared to estimates for

    the EMU or the United States, Romanian firmsdisplay a lower preference toward markup pricing

    and a higher one toward market pricing. Markup

    pricing is more prominent among firms in the

    manufacturing sector (for 46% of these it is the

    most preferred strategy)11 and especially in the

    case of large firms (74% of the total), while small

    firms are generally more likely to prefer market

    pricing. This makes sense, as larger firms have

    higher autonomy over their price-setting process

    and are more likely to operate in a monopolistic

    market, thus their choice of markup pricing is

    more probable. This pattern is also consistent with

    earlier results on perceived competition and the

    higher occurrence of long-term customer relations

    in the case of larger versus smaller firms. The

    difference in perceived competition partly explains

    the contrast between our results and those

    reported for most EMU countries by Fabiani

    et al. (2005), where smaller firms were more likely

    to adopt markup pricing while perceiving a lower

    competition when compared with large firms

    (Figure 1).

    Price discrimination can represent an additional

    feature of the price-setting process, as some firms

    may attempt to use this as a means of extracting

    part of the consumer surplus. We seek to find out

    whether such a strategy is used by sampled firms

    by asking them if their unit price is the same for all

    units sold or else depends on quantity sold or other

    Figure 1. Price setting features inside the company.

    factors.12 Firms (44%) declared that they charge

    the same price for all customers. This figure might

    seem low at first glance, but it is in fact relatively

    high when compared with EMU evidence (around

    20%, according to Fabiani et al., 2005).

    The New Keynesian literature stresses the

    importance of forward-looking factors in

    modeling macroeconomic variables such asinflation. While purely forward-looking Phillips

    curves are rarely used in forecasting models, the

    most widespread specification has become that of

    a hybrid Phillips curve, such as the ones proposed

    by Fuhrer (1997) or Smets (2003). Although we are

    aware of the possible limitations of survey

    evidence in this debate, we asked firms to weigh

    their use of backward against forward-looking

    information. Unsurprisingly, the great majority of

    firms (78%) said they use a combination of past

    information and price projections, which would

    support a hybrid Phillips curve rather than pure

    forward or backward-looking-based pricing rule.

    3.3.2 The when and the how much in the pricing

    decision

    Both time- and state-dependent models assume

    that firms operate in an environment of imperfect

    competition, that is, they are price setters.

    However, while time-dependent pricing models

    like the ones of Taylor (1999), Calvo (1983) or

    Fischer (1980), assume a constant duration of

    price quotation, synchronized within store pricechanges13 with firms not being able to respond to

    shocks that occur in the intervals between two

    predetermined adjustments, in state-dependent

    pricing models, such as those pioneered by

    Sheshinski and Weiss (1977), price changes do

    not depend on fixed periods of adjustment, but

    rather they are triggered by comparison between

    the distance to the optimal price and some

    predetermined costs of adjustment. In these latter

    models, prices are thus allowed to respond to

    shocks and frequency of price adjustments is

    random.

    In order to test which of these theories seems tobetter explain Romanian firms timing of price

    changes, the subjects of our survey were asked if

    their prices are reviewedwithout necessarily

    being changed(i) at regular time intervals, (ii)

    just as a reaction to shocks, or (iii) usually at fixed

    periods but also in reaction to certain events

    (Figure 2).

    The answers revealed that approximately 15%

    of the firms appear to follow a purely time-

    dependent rule, 43% follow a purely state-

    dependent rule, while the rest employs a mixed

    strategy. Time-dependent pricing is above average

    in the case of firms from agriculture (34%) and

    energy, gas and water supply (47%), which can be

    explained by the seasonality of prices and by

    regulatory guidelines, respectively.14 Small firms

    follow mostly state-dependent strategies, while for

    medium and large firms, the mixed strategy is

    mostly preferred. For the latter, the proportion

    preferring a time-dependent policy is slightly

    above the sample average, which is consistent

    with the IPN data, where the preference for time-

    dependent pricing is directly proportional to firm-

    size (Fabiani et al., 2005).15

    Firms were also asked about the number of

    price revisions and the number of price changes for

    the year 2005. Although all firms were asked to

    answer, the focus was on firms choosing a strategy

    Figure 2. Price reviewing process: time versus state dependent elements.

    with time-dependent elements and the results

    presented here refer to these. Survey answers

    indicate a much lower degree of price stickiness

    for Romanian firms compared to Eurosystem

    countries covered by Fabiani et al. (2005). While

    for the former, the average frequency of price

    reviews is circa 4.4 times per year (that is

    approximately once every 2.7 months), themedian frequency of price changes/reviews in the

    Euro area is around once per year.16 This

    difference comes as no surprise considering the

    history of high inflation in Romania. Price changes

    for firms following pure or mixed time-dependent

    rules amounted to around 2.5 times per year (on

    average every 5 months). Price reviews were thus

    taking place more often than price changes,

    roughly in a 2:1 ratio for most firms, with the

    exception of the energy, water and gas sector

    where the frequencies of reviews and changes are

    equal, due to regulatory requirements. Large firms

    review and change their prices much more often

    than medium or small ones. Although inconsistent

    with the finding on perceived competition, this

    latter aspect might be the result of a stronger

    concern regarding costs of mispricing, a higher

    diversity of their products leading to

    complementarities in price setting in case of large

    firms (Table 1).

    In a question related to the one on frequency of

    price reviews/changes, we also asked firms about

    the frequency of wage adjustments. More than half

    (58%) of respondents indicated only one wage

    adjustment a year (with a further 14% indicating

    even less than one change a year), which suggests

    that in the Romanian case, wages are much

    stickier than prices. Wage stickiness is often

    brought up in the context of a New Keynesian

    model as an explanation of the empiricallyfounded inertia in both inflation and real output

    (Blanchard and Gali, 2007).

    Besides inquiring on the frequency of price

    changes, we were also interested in the magnitude

    of a typical price increase/decrease in 2005 and

    particularly to potential asymmetries between

    price increases and decreases. The choices were

    grouped in four intervals centered on 8%, which is

    close to the level of CPI inflation for 2005. The

    results of the query suggest the existence of a

    certain degree of asymmetry, as price increases are

    more evenly distributed between the 04% and the

    48% brackets, while price decreases are obviously

    skewed toward the 04% interval (Figure 3).

    This type of asymmetry is also manifest with

    respect to the direction of price changes (there

    were only 286 answers for the magnitude of a

    typical price increase and 129 answers for the

    magnitude of a typical price decrease). While

    the prevalence of upward price changes in the

    Romanian case is to be expected due to moderate-

    to-high inflation environment, one may also

    emphasize the role of the higher frequency and

    magnitude of inflationary shocks in 2005:

    administered price and excise tax hikes in April,

    bad agricultural crops due to two rounds of floods,

    large upswings of the international oil price and

    the positive demand shock due to the introduction

    of a flat income tax rate of 16%. Looking across

    economic sectors, the highest proportion of largeprice increases (i.e. larger than 12%) was obtained

    for firms in the public utilities sector (electricity,

    gas and water supply). Together with the data on

    price change frequencies for this sector, this comes

    to confirm the intuition that regulated prices are

    modified less often than market prices, but when

    they are, they tend to come in relatively large

    shocks. As for the largest price decreases, these are

    mostly characteristic of firms in the agricultural

    sector. This again is an intuitive result, since food

    prices (especially fruit and vegetables) are known

    to have a strong seasonal pattern, with large price

    discounts recorded in the third-quarter of every

    year.

    3.4. Theories of Price Stickiness and Determinants

    of Price and Wage Changes

    3.4.1 The why not in pricing decisions

    Different explanations have been advanced by

    economists to motivate price stickiness. Our

    survey listed seven such explanations for firms to

    assess their importance. The choice was made byinvestigating similar studies and eliminating some

    explanations, which were inappropriate for the

    Romanian context.17 The tested theories, together

    with the results are presented in Table 2.

    The answers received to this question indicate

    that only two of the above factorsthe implicit

    contracts and the explicit contractswere regarded

    as important (i.e. scored above 3). The implicit

    contract theory assumes the existence of an invisible

    mutual agreement between firms and customers that

    prevents firms from changing prices. Rotemberg

    (2005) argues that a reason for nominal price

    rigidities is that some price changes are perceived

    by consumers as unfair. Thus, firms avoid suchchanges, giving extra signals on their loyalty to

    customers through periods of stable prices. Explicit

    contracts theory refers to the idea that, until

    eventual re-negotiation, firmclient relationships

    are governed by the constraints imposed by

    written contracts.

    All other options scored as less important, i.e.

    below the neutral threshold of 2.5. These included

    quality adjustmentsreferring here mainly to

    price decreases, namely to the case that a price

    decrease may signal to customers a reduction in

    product qualityand price readjustments. The

    latter refers to firms being reluctant to change

    prices in a given direction for fear of having to

    change it in the opposite direction in a short period

    of time.

    Coordination failure theory ranked fifth

    overall. According to this theory, firms hesitate

    to change prices for fear of being the only ones

    doing so, preferring instead to wait for others to

    make the first move, which implies a high degree of

    synchronization in the timing of price changes

    across vendors.

    Information and menu costs rank last in the

    present survey, although they are often cited as

    the main reasons for justifying price stickiness. The

    information costs concept is part of a broader

    understanding of menu costs, referring mostly to

    the time and attention required of managers to

    gather the relevant information and make and

    implement decisions(Ball and Mankiw, 1994). The

    low importance managers confer to this theory

    points toward the prevalence of the rigidities in the

    second stage of the price-setting process. Menu

    costs theory which refer here to the narrow sense ofthe concept, namely that firms tend to keep their

    prices unchanged because price changes imply

    physical costs (e.g. printing new catalogues,

    changing the price tags, changing the information

    posted on their websites) has the lowest importance

    in explaining price stickiness.

    Overall, the results are consistent with those

    showing the dominance of long-term customer

    relationships (for 85% of firms) and other firms

    being the main clients (for around 71% of our

    survey respondents). The gap between the scores

    obtained by the implicit and explicit contract

    theories and the other five factors is uniform

    across sectors and firm size.

    Although equally important from a statistical

    point of view at aggregate level, explicit and

    implicit contracts have different relativeimportance across firm size and across economic

    sectors. Thus, explicit contracts are considered

    more important by firms from the public utilities

    (energy, gas and water supply) and constructions

    sectors, reflecting the contractual nature of these

    activities, while implicit contracts are dominant for

    the wholesale and retail trade group. Furthermore,

    explicit contracts importance is increasing with

    firm size, while the implicit contracts relative

    ranking is inversely related to it. This is perhaps a

    reflection of small firms client base having a larger

    inclusion of population as main clients compared

    to the overall sample.

    All national surveys conducted in the context of

    the Eurosystems IPN project included some form

    of testing of the main theories of price stickiness in

    their query. Fabiani et al. (2005), who summarize

    the results obtained up to the publication date,

    report that implicit and explicit contracts are

    ranked first and second across the euro area, a

    result similar with the one obtained in the current

    study. However, due to the heterogeneity of scores

    across countries, the average scores for these two

    theories are lower than the ones reported here (see

    Kwapil et al., 2005, for similar magnitude of the

    results). These two factors also score well in the

    studies performed outside the IPN framework. For

    example, implicit contracts are ranked first in the

    study of Apel et al. (2005) for Sweden, while

    explicit contracts lead the way for UK firms as

    reported by Hall et al. (1997). The exception is the

    study by Blinder et al . (1998), where implicit

    contracts are ranked fourth, while the explicit

    contract theory is ranked fifth. A possible

    explanation for the different ranking obtained by

    Blinder et al. (1998) may consist of the different

    way the questionnaire was administered, namelythrough direct meetings with the managers of the

    sampled firms, while in the other studies, the

    current included, the (e)mail was the preferred

    option.

    3.4.2 The why in the pricing decisions

    As for the main determinants of price changes,

    respondents were asked to assess on a scale from

    4(very important) to 1(not important) the

    importance of each of a list of underlying

    factors, separately for price increases and for

    price decreases. The factors considered were

    similar to those used in similar studies (Table 3),

    except that we included as additional determinants

    exchange rate fluctuations and the inflation rate.

    The reason is linked to the historical pattern of

    some Romanian firms automatically indexing

    their prices to the exchange rate or to past or

    anticipated inflation rates, which in itself

    represents a characteristic of price-setting

    behavior in countries with a high inflation and

    volatile exchange rate environment.

    The gap between raw material costs (scoring

    3.4) and labor costs (scoring almost 3) at the top of

    price-increasing factors is large, probably

    reflecting a relatively lower correlation between

    price and wage dynamics. This should be

    corroborated with evidence on determinants of

    wage changes presented below, suggesting that the

The p-values were computed for testing the hypothesis that the mean of a given theory is the same as that of thetheory ranked just below with the exception of the other option.

    wages are better correlated with productivity

    growth than with inflation. Notwithstanding the

    faster disinflation and the significant currency

    appreciation of the recent years, exchange rate

    movements and the inflation rate still play a

    relatively important role in Romanian firms

    price setting, especially compared with financial

    costs which received a low score. This presumablyreflects Romanian firms relying more heavily on

    internal resources and trade credit to finance their

    activities and much less on resources borrowed

    from financial institutions (NBR, 2007).

    Although the actual average scores have

    different magnitudes, our factor rankings look

    rather similar to those reported by Fabiani et al.

    (2005) for the euro area average. Thus, in both

    cases, the changes in the cost of raw materials and

    those in labor costs are at the top of the drivers of

    price increases and the changes in competitors

    prices, those in raw material costs and the

    fluctuations in demand lead the hierarchy of

    price decrease determinants. Furthermore, the

    asymmetry between the causal factors of positive

    and negative price changes shows similar patterns

    to the IPN results, with supply side factors being

    more relevant for price increases and less so for

    price decreases, while the reverse is true about

    demand side factors. Inflation and exchange rate

    fluctuations (to a lower extent though), the items

    specific to our survey, act in a similar manner with

    the cost factors, exerting a stronger influence on

    price increases than on price cuts. This is again a

    reflection of the specificity of the Romanian

    macroenvironment in terms of high inflation and

    volatile exchange rate (especially after the

    liberalization). Figure 4 presents the asymmetry,

    computed as the difference between the average

    score received by a specific factor for price

    increases and decreases.

    In a related question, firms were also asked

    about the main factors affecting wage changes.

    Respondents had to choose from variation in four

    factors, namely: productivity, inflation, taxes and

    demand. Only changes in productivity were

    considered more than important (scored above

    3), while the other three factors had average scores

    around the neutral level of 2.5 (Table 4). The

    ranking of the factors were generally similar across

    large sectors and firm size.The below shown ranking, together with the low

    importance of inflation being supported also by the

    finding that approximately 63% of the firms do not

    index their wages to inflation,18 should be taken

    with a grain of salt for several reasons. First, a few

    explaining factors of wage dynamics may have been

    left out, such as labor market shortages or exchange

    rate developments (given that some companies

    negotiate salaries in euro terms), which may have

    biased to some extent the answers we received.

    Second, some respondents may have had difficulties

    in distinguishing between productivity growth

    (measured in real or output terms) and total or

    per employee revenue growth (which is measured in

    nominal terms), thus implicitly including inflation in

    the answer, which should have referred solely to

    productivity dynamics. Third, some respondents

    may have viewed the choice of productivity growth

    as the right answer to give, thus perhaps

    misrepresenting actual firm practices. This might

    be the case for instance for the public utilities sector

    whose answers distribution is strongly skewed

    toward the productivity option, although index-

    ation practices persist.19

    3.5. Reaction to Potential Financial Shocks20

    Investigating the reaction of firms to potentialfinancial shocks in a survey form is a new approach

    introduced by this paper. Table 5 presents the six

    scenarios and the received average scores. These

    scenarios were tailored to count for a shock of

    approximately 10 or 30% domestic currency

    depreciation (and 20% appreciation, respectively)

    and an almost twofold hike in interest rates (RON

    or EUR). At the time the companies received the

    questionnaire (SeptemberNovember 2006), the

    exchange rate was quoted at around 3.5 RON/

    EUR and the average domestic interest rates for

    outstanding loans granted to companies were

    around 13.5% for domestic currency loans and

    7.2% for loans in EUR.

    Strong potential exchange rate movements

    generally received a higher overall average score

    than the scenarios looking at interest rate

    movements. The results were in line with

    expectations, mainly because in 2005: (i) most of

    the Romanian companies (and 45% from the

    adjusted sample) did not take loans and disposed

    of sizeable bank liquidities; these firms were net

    creditors to the banking sector, and a hike in

    the interest rates might even positively affect

    them; overall, the Romanian firms rely to a

    greater extent on internal resources and on trade

    credit to finance their activities than on resources

    borrowed from financial institutions; this is also

    reflected by the relatively low level of financial

    intermediation;21 and (ii) the share of foreign

    currency loans (domestic and external) in total

    loans granted to firms has been quite important in

    the case of Romania standing at 64% in December

    2006 (NBR, 2007).

    Furthermore, the preliminary information from

    the earlier questions in the survey showed that while

    both exchange rate movements and financial cost

    factors ranked below most factors listed for the

    explanation of price changes, the average scoreswere statistically higher in the case of exchange rate

    movements as compared with financial costs, for

    both price decreases and increases.

    However, only the leading scenario (exchange

    rate depreciation to 4.6 RON/EUR) and the one

    having the lowest average score (an increase of

    interest rate to EUR/USD credits to 15%) are

    statistically different from the one below (above),

    both when the impact on prices and that on costs

    are considered. The overall average scores are

    high, reflecting the shock potential these scenarios

    have.

    The price and cost impacts are similar (from a

    statistical point of view) for all scenarios but that

    assuming an exchange rate appreciation to 2.7

    RON/EUR. Thus, one might argue that, except

    for this scenario, firms fully transmit into their

    prices the impact of shocks. In a model where

    firms keep their prices stable because they are

    concerned about losing customers or market share

    (an important factor for the sampled firms

    considering the high ranking implicit contracts

    received among price stickiness factors),

    Kleshchelski and Vincent (2008) show that

    shocks affecting the marginal cost of a single

    firm have a lower pass-through to prices than in

    the case when an entire sector is hit (24% in the

    former case and 62% in the latter). If one

    considers that the shocks that we listed in our

    questions usually affect entire sectors, the high

    average scores are thus being explained.

    Large companies register higher scores in case

    of a sudden move in EUR/RON exchange rate. An

    explanation might be that according to their

    balance sheet data, these companies bear almost

    60% of the total unhedged foreign exchange risk

    belonging to the Romanian corporate sector.

    Related to this, as mentioned before, the main

    clients are represented by foreign entities in a wellabove average proportion. Small firms in their

    turn rank higher the importance of the scenario of

    the interest rate to RON loans soaring at 30%.

    This might be due to the large and increasing

    position of SMEs as net debtors to the banking

    sector (amounting to 15% of their total balance

    sheet, as compared with the SMEs from the euro

    area, which currently retain a net debtor position

    of only 23%, NBR, 2007).

    4. CONCLUSIONS

    Using a survey-based approach, similar to those

    employed by the Eurosystem in its IPN project,

    the current paper investigates the price-setting

    behavior of Romanian firms in 2005. In

    interpreting the results, one should take into

    account the relatively low answer rate, which is

    about half that of the average registered for the

    IPN studies.

    Although operating in a competitive

    environment, most of the firms claim to have full

    autonomy in setting the price of their main

    product. Among these, around half use the

    market price as the main pricing rule, with a

    slightly lower share of firms setting the price as a

    mark-up over costs. Differing from the IPN

    findings, small firms perceive a higher degree of

    competition and predominantly adopt the market

    price, while lower perceived competition is

    consistent with medium and large firms using

    mostly mark-up pricing.

    The large majority of firms use a combination ofbackward and forward-looking information when

    reviewing prices. Around 60% of firms use either a

    time-dependent pricing rule or one that incorporates

    both time- and state-dependent elements. Pure

    state-dependent pricing is dominant only in the

    case of small firms.

    Romanian firms revised and changed their

    prices in 2005 much more frequently than what

    the evidence summarized in Fabiani et al. (2005)

    suggests was the case for euro zone firms.

    Conditional on following a time and mixed-

    dependent pricing rule, Romanian prices were

    revised quarterly and changed on average every

    5 months. Large firms revised and changed their

    price much more often than medium and small

    ones, probably due to more significant costs of

    mispricing their products and lower costs of priceoptimization. Wages are found to be stickier than

    prices, with around 72% of firms changing their

    wages once per year or less often.

    Costs of raw materials in the case of price

    increases and competitor prices, raw materials

    costs and demand changes in case of price

    decreases are the main factors determining price

    changes. Implicit and explicit contracts rank first

    when it comes to the main causes of price

    stickiness, similar to the rankings obtained for

    selected EMU countries.

    Firms fully transmit into their prices the impact

    of large unanticipated financial shocks. Large

    variations of the exchange rate are typically

    perceived more strongly than interest rate shocks.

    At this stage, further analysis should be carried out

    in complementing the present evidence with

    research based on microdata used for CPI

    compilation.

    NOTES

    1. One such approach is to analyze data on a cross-section of products within a particular sector/firm(e.g. Kashyap, 1995; Levy et al., 1997). Anotherapproach is based on analyzing disaggregated dataused for the construction of the CPI/PPI indices(e.g. Bills and Klenow, 2002).

    2. Fabiani et al. (2005) offer an overview of the survey-based results for selected euro area countries.

    3. The only related research analyses either firm-leveldata (Copaciu, 2004, and Ratfai, 2007, forHungary) or micro-CPI data (Coricelli andHorvath, 2006, for Slovakia and Gabriel andReiff, 2007, for Hungary).

    4. Weighted average results based on data presented inFabiani et al. (2005).

    5. Real GDP growth has averaged 5.7% p.a. between2001 and 2005, while average real wage and creditgrowth rates for the same period were 27.4 and49.3%, respectively (NBR, 2007).

    6. This is reflected by the fact that the 19.83% of thesampled firms that returned the questionnaireactually accounted for 67% of the total number ofemployees in the sample. The procedure followsclosely that used by Kwapil et al. (2005) forAustrian firms.

    8. More precisely 47% in the case of Romania, a figuresimilar with that obtained in the case of Portugal(Martins, 2005).

    9. Although in their case there is a predominance ofthe industrial sector in the national samples, whichis not our case.

    10. Almost 29% of the respondents did not answer thisquestion. However, this is a low figure since for asimilar question less than half of the firms answeredin Italy (Fabiani et al ., 2004) and Belgium(Aucremanne and Druant, 2005).

    11. Except for firms in the electricity, water supplyand gas sector for which prices are generallyregulated.

    12. Price discrimination according to the quantity soldis higher for large firms (54%), while small firmsdiscriminate less than the medium and larger ones(47% charge the same price), facts consistent againwith the degree of perceived competition.

    13. While Taylor assumes that the price-setter knows in

    advance, through contracts, the path of the price-adjustment process, in Calvos model the price isaltered only when the firm receives a random signalthat follows an exogenously specified distribution.Fischer (1980) instead assumes that prices arepredetermined but not fixed; different prices foreach period are possible when multi-periodcontracts are established.

    14. A similar pattern is obtained in the case of Spain(A lvarez and Hernando, 2005).

    15. Overall, the share of firms choosing a time-dependent strategy alone is smaller whencompared with the average for the United States(40%, Blinder et al., 1998), the United Kingdom(79%, Hall et al ., 1997) and the EMU (34%,Fabiani et al ., 2005), but there are somesimilarities to the results obtained in the case ofindividual countries such as Belgium (26%,Aucremanne and Druant, 2005) and Sweden(23%, Apel et al., 2005).

    16. Although there are countries where price reviews aretaking place quarterly like Austria or France(Fabiani et al.).

    17. For example, the pricing points theory could not beapplied due to the denomination of the Romaniancurrency, which took place throughout the periodfirms should relate their answers to.

    18. Only approximately 24%/13% of firms declared toindex wages to past/expected inflation. This may be

    a reflection of improving inflation expectations,following an almost uninterrupted trend ofdisinflation in the 20012007 period, with theaverage inflation falling to a single-digit level aslate as 2005.

    19. More than 50% of the firms from this sectorindicated the indexation of wages either to past orexpected inflation.

    20. It should be mentioned that the higher complexityof this section resulted in a slightly lower number ofanswers being received.

    21. The nongovernment credit to GDP ratio was 21.1%in 2005 and 27.2% in 2006, while similar ratios forthe euro area countries have been consistently largerthan 100% (NBR, 2007).
