you can t save alone commitment in rotating savings and credit associations in kenya abstract this article examines one reason why individuals develop and maintain local level financial savings organizations known as rotating savings and credit organizations or roscas economic theories suggest that individuals form roscas to finance the purchase of a lumpy durable good in response to intrahousehold conflict over savings or to provide themselves with insurance the article proposes an additional hypothesis for rosca participation saving requires discipline and some roscas may be formed to provide a collective mechanism for commitment in the presence of time inconsistent preferences data from 70 roscas located in western kenya indicate that the commitment hypothesis is plausible and broadly consistent with the design and patterns of participation in these roscas as many rosca participants put it you can t save alone

the microfinance promise in the past decade microfinance programs have demonstrated that it is possible to lend to low income households while maintaining high repayment rates even without requiring collateral the programs promise a revolution in approaches to alleviating poverty and spreading financial services and millions of poor households are served globally a growing body of economic theory demonstrates how new contractual forms offer a key to microfinance success particularly the use of group lending contracts with joint liability for the most part however high repayment rates have not translated into profits and studies of impacts on poverty yield a mixed picture in describing emerging tensions the paper highlights the diversity of innovative mechanisms beyond group lending contracts the measurement of financial sustainability the estimation of economic and social impacts the costs and benefits of subsidization and the potential to reduce poverty through savings programs rather than just credit the promise of microfinance has pushed far ahead of the evidence and an agenda is put forward for addressing critical empirical gaps and sharpening the terms of policy discussion

group lending repayment incentives and social collateral abstract in this paper we investigate the impact on repayment rates of lending to groups which are made jointly liable for repayment this type of scheme especially in the guise of the grameen bank in bangladesh has received increasing attention we set up and analyze the repayment game which group lending gives rise to our analysis suggests that such schemes have both positive and negative effects on repayment rates the positive effect is that successful group members may have an incentive to repay the loans of group members whose projects have yielded insufficient return to make repayment worthwhile the negative effect arises when the whole group defaults even when some members would have repaid under individual lending we also show how group lending may harness social collateral which serves to mitigate its negative effect

food insecurity and public assistance this paper examines if welfare programs reduce the probability that vulnerable households experience food deprivation because of financial constraints although the 1996 welfare reform legislation specifically limited the eligibility of immigrant households to receive assistance many states chose to protect their immigrant populations by offering state funded aid to these groups i exploit these changes in eligibility rules to examine the link between food insecurity and public assistance the evidence indicates that a 10 percentage point cut in the fraction of the population that receives public assistance increases the fraction of food insecure households by about 5 percentage points

gender norms in financial markets evidence from kenya abstract the role of institutions rules and norms in markets is increasingly recognized in development discourse this paper considers the role of gender relations for rules and norms in financial markets using evidence from central kenya it develops a framework for establishing the influence of gender on the demand for and access to financial services so explaining the gender differentiated use of rotating savings and credit associations roscas it first analyzes intrahousehold norms related to income and expenditure flows and their management so identifying gendered patterns of demand second by conceptualizing financial intermediaries as operating within rules and norms it allows the influence of gender relations on access to financial services to be more systematically investigated

household history snap participation and food insecurity abstract food security in an important public policy issue in 2015 approximately 1 in 8 u s households experienced food insecurity at some point in the year low income families are at higher risk for food insecurity than other families and these families may also face higher levels of disruption e g moves loss of income or individuals entering or leaving the household than other families i use data from the survey of income and program participation to explore the relationship between food insecurity the household s history during the previous year and snap participation the results indicate that a number of aspects of the household s recent experience including negative income shocks moves and both increases and decreases in household size increase the probability of being food insecure while snap participation is estimated to reduce the probability of being food insecure

keep your friends close the effect of local social networks on child human capital outcomes abstract social networks can affect demand for human capital investments by relaxing household time or budget constraints or by defining and reinforcing human capital preferences however empirically identifying the effect of social networks on human capital investment is usually problematic because households self select their networks in ways that may be correlated with their abilities to make these investments in northern ugandan internally displaced persons camps networks were not entirely self selected rebel activity which forced households into camps in 2002 disrupted pre existing social networks in ways that were exogenous to household human capital preferences this paper uses the exogenous variation in network disruption to identify a positive impact of networks on children s long term nutritional outcomes

the effect of safety net programs on food insecurity we investigate to what extent major safety net program benefits affect food insecurity in families we impute program eligibility and benefits in each state for 2001 2009 accounting for cross program eligibility rules we use simulated eligibility and benefits for a nationally representative sample as instruments for imputed eligibility and potential benefits among nonimmigrant low income single parent families 1 000 in potential cash or food benefits reduces the incidence of food insecurity by 1 1 percentage points on a base of 33 percent cash and food both reduce food insecurity the results highlight the importance of jointly considering a full range of safety net programs

rasch analyses of very low food security among households and children in the three city study the longitudinal three city study tcs of low income families with children measures food hardships using fewer and some different questions from the standard u s instrument the household food security survey module hfssm in the current population survey cps we use a rasch measurement model to identify thresholds of very low food security among households and among children in the tcs that are comparable to thresholds from the hfssm we also use the tcs to empirically investigate the determinants of food insecurity and of these specific food insecurity outcomes estimating a multivariate behavioral rasch model that is adapted to address longitudinal data the estimation results indicate that participation in the supplemental nutrition assistance program and the temporary assistance for needy families program reduce food insecurity while poverty and disability among caregivers increase it besides its longitudinal structure the tcs measures many more characteristics about households than the cps our estimates reveal that financial assistance through social networks and a household s own financial assets reduce food insecurity while its outstanding loans increase insecurity

the harambee movement and efficient public good provision in kenya abstract those familiar with kenya since independence will know of the importance of the harambee system the term harambee has come to mean the provision of goods usually social infrastructure through the voluntary cooperation of members of the community provision of public goods in this way is an important alternative to the more normal method provision through tax finance here we compare these two methods of provision with a view towards determining first the circumstances under which harambee might be more effective and second what policies might be pursued to best utilize this system

the geography of linguistic diversity and the provision of public goods abstract this paper analyzes the importance of local interaction between individuals of different ethnolinguistic groups for the provision of public goods at the national level the conceptual framework we develop suggests that a country s public goods i decrease in its overall ethnolinguistic fractionalization and ii either increase or decrease in its local global ethnolinguistic complementarity a measure of how local interaction affects antagonism towards other groups in the society at large after constructing a 5 km by 5 km dataset on language use for 223 countries we empirically explore these theoretical predictions while overall fractionalization worsens public goods outcomes local interaction mitigates this negative association conditional on a country s overall diversity public goods outcomes are maximized when there are a few large sized groups and the diversity of each location mirrors that of the country as a whole

does industrialization build or destroy social networks abstract this article estimates the relationship between changes in industrialization and changes in social networks measures in indonesia during 1985 97 using repeated cross sections of nationally representative surveys we analyze a rich set of social interaction measures including various measures of voluntary associational activity levels of trust and informal cooperation districts that experienced rapid industrialization showed significant increases in most measures of social interaction however districts that neighbor rapidly industrializing areas exhibited high rates of out migration significantly fewer community credit cooperatives and a reduction in mutual cooperation as assessed by village elders manufacturing growth can be thought of as a proxy for income growth here the findings are contrary to several recent claims regarding the role of social capital in economic development

the economics of roscas and intrahousehold resource allocation this paper investigates individual motives to participate in rotating savings and credit associations roscas detailed evidence from roscas in a kenyan slum nairobi suggests that most roscas are predominantly composed of women particularly those living in a couple and earning an independent income to explain this phenomenon we propose an argument based on conflictual interactions within the household participation in a rosca is a strategy a wife employs to protect her savings against claims by her husband for immediate consumption the empirical implications of the model are then tested using the data collected in kenya

local political business cycles evidence from philippine municipalities abstract this paper establishes the existence of short term political business cycles in the philippines over the period 2003 2009 examining a balanced panel of 1143 municipalities shows that employment levels increase in the two pre electoral quarters and drop sharply in the two quarters following elections further results are consistent with the cycles being generated by incumbents attempts to increase their chances of re election cycles are stronger in sectors that incumbents are more able to influence and when they expect stronger electoral competition evidence suggests that these cycles are detrimental to development

immigration ethnic diversity and political outcomes evidence from denmark i study the impact of immigration and increasing ethnic diversity on political outcomes in immigrant receiving countries focusing on immigration and election outcomes in danish municipalities 1981 2001 a rich set of control variables isolates ethnic diversity eects from those of other immigrant characteristics and a novel iv strategy based on historical housing stock data addresses issues of endogenous location choices of immigrants increases in local ethnic diversity lead to right ward shifts in election outcomes by shifting electoral support away from traditional big government left wing parties and towards anti immigrant nationalist parties in particular these eects appear in both local and national elections

is there reciprocity in a reciprocal exchange economy evidence of gendered norms from a slum in nairobi kenya norms of reciprocity help enforce cooperative agreements in bilateral sequential exchange we examine the norms that apply in a reciprocal exchange economy in our one shot investment game in a nairobi slum people adhered to the norm of balanced reciprocity which obligates quid pro quo returns for any level of trust the norm is gendered with people more likely to comply when confronted with women rather than men and differs from conditional reciprocity prevalent in developed countries according to which greater trust is rewarded with proportionally larger returns balanced reciprocity produces less trust and trustworthiness and smaller gains from trade than conditional reciprocity jel c72 c91

ethnic networks and access to credit evidence from the manufacturing sector in kenya it is often anecdotally observed that networks can facilitate exchange but there are few empirical studies that explore the significance of such networks in this paper the authors analyze the impact of ethnic networks on access to finance of kenyan firms using an exceptionally rich data set the authors find that ethnicity does not affect access to formal sources of finance but being a member of an ethnic group is significant in explaining access to informal sources of finance like supplier credit the authors interpret these results in terms of information and contract enforcement mechanisms that work within ethnic groups but not across them

randomized evaluations of educational programs in developing countries some lessons this paper reviews recent randomized evaluations of educational programs in developing countries including programs to increase school participation to provide educational inputs and to reform education it then extracts some lessons for education policy and for the practice and political economy of randomized evaluations

the asymmetric role of corporate governance in ceo pay determination evidence from south africa previous studies suggest that ceos may be incentivised to pursue actions aimed at restoring equity when pay deviates from the predicted ceo labour market compensation rate this study investigates

environmental performance in socially fragmented countries social fragmentation is often associated with reduced co operative behaviour which undermines public goods provision such as environmental protection the few studies linking social fragmentation and environmental performance have been confined to using ethnic fractionalisation as the only measure of social heterogeneity in this paper we contribute to the literature in a twofold manner first we bring into the analysis alternative measures of social fragmentation i e religious fractionalisation ethnic religious polarisation that have received considerable attention in development economics in recent years second this is the first study to our knowledge that makes use of a large panel dataset of several environmental indicators to explore links between ethnic religious diversity and the environment we find that all indices of social fragmentation are negatively linked to measures of environmental quality although for some of them the size of the effect is larger in the case of polarisation

the development of the neoclassical tradition in labor economics this essay on labor economics examines neoclassical theory s rise to ascendancy following the second world war with a secondary focus on the relative decline but continued influence of institutionalist economic theory the authors describe the evolution of institutional and neoclassical theory from the late nineteenth to mid twentieth centuries examine some early intellectual debates between the two camps briefly describe the work of neoclassical labor economics pioneers and look at major developments over the past 30 years they argue that neoclassical economists increasing intellectual breadth and influence in public policy have led them to pay closer attention to issues that have long been of concern to institutionalists and neoinstitutionalists

enforcement socioeconomic diversity and tax filing compliance in the united states in this article we examine the determinants of tax filing compliance in the united states we use county level data on non filing rates for the tax year 2000 obtained directly from the internal revenue service we include explanatory variables identified in the rational compliance framework including an enforcement index against identified non filers the audit rate of filers and the average penalty rate for both filers and non filers we also examine the role of socioeconomic diversity on tax compliance testing whether within county heterogeneity in household income language race and religion can help explain variation in non filing rates we find that non filing is increasing with heterogeneity by race although not by income or language and that non filing is decreasing with heterogeneity by religious membership as for enforcement variables we find that non filing rates tend to fall with the enforcement index other variables have somewhat mixed results

substitutes or complements a configurational examination of corporate governance mechanisms we conduct an exploratory qualitative comparative case analysis of the s p 1500 firms with the aim of elaborating theory on how corporate governance mechanisms work together effectively to do so we integrate extant theory and research to specify the bundle of mechanisms that operate to mitigate the agency problem among publicly traded corporations and review what previous research has said about how these mechanisms combine we then use the fuzzy set approach to qualitative comparitive analysis qca to explore the combinations of governance mechanisms that exist among the s p 1500 firms that achieve high and not high profitability our findings suggest that high profits result when ceo incentive alignment and monitoring mechanisms work together as complements rather than as substitutes furthermore they show that high profits are obtained when both internal and external monitoring mechanisms are present at the same time however monitoring mechanisms evidently combine in complex ways such that the

optimal executive compensation versus managerial power a review of lucian bebchuk and jesse fried s pay without performance the unfulfilled promise of executive compensation this essay reviews lucian a bebchuk and jesse m fried s pay without performance the unfulfilled promise of executive compensation bebchuk and fried criticize the standard view of executive compensation in which executives negotiate contracts with shareholders that provide incentives that motivate them to maximize the shareholders welfare in contrast bebchuk and fried argue that executive compensation is more consistent with executives who control their own boards and who maximize their own compensation subject to an outrage constraint they provide a host of evidence consistent with this alternative viewpoint the book can be evaluated from both positive and normative perspectives from a positive perspective much of the evidence they present especially about the camouflage and risk taking aspects of executive compensation systems is fairly persuasive however from a normative perspective the book conveys the idea that policy changes can dramatically improve executive compensation systems and consequently overall corporate performance it is unclear to me how effective potential reforms designed to achieve such changes are likely to be in practice

partial identification methods for evaluating food assistance programs a case study of the causal impact of snap on food insecurity we illustrate how partial identification methods can be used to provide credible inferences on the causal impacts of food assistance programs focusing on the impact that the supplemental nutrition assistance program snap formerly known as the food stamp program has on food insecurity among households with children recent research applies these methods to address two key issues confounding identification missing counterfactuals and nonrandomly misclassified treatment status in this paper we illustrate and extend the recent literature by using data from the survey of income and program participation sipp to study the robustness of prior conclusions the sipp confers important advantages the detailed information about income and eligibility allows us to apply a modified discontinuity design to sharpen inferences and the panel nature allows us to reduce uncertainty about true participation status we find that snap reduces the prevalence of food insecurity in households with children by at least six percentage points

industrial policy in an imperfect world theoretical analyses of industrial policy normally restrict the range of possible outcomes by abstracting from either market or government failures this paper thus studies industrial policy and its effectiveness in a model that includes both market and government imperfections we introduce a public agency responsible for industrial policy into the model of hausmann and rodrik 2003 and assume that this agency has limited information and is partly politically motivated we further extend the model to allow the public agency to communicate with entrepreneurs and the entrepreneurs to engage in rent seeking we find that industrial policies are ineffective if the public agency is poorly informed but that they are not necessarily ineffective if the public agency is highly politically motivated given a highly politically motivated public agency industrial policies are effective if and only if the institutional setting ensures that such policies are modest e g by restricting the public agency s budget moreover our model helps us to understand why the same industrial policies that have failed elsewhere have been relatively successful in south korea and taiwan

ethnic diversity social sanctions and public goods in kenya abstract this paper examines ethnic diversity and local public goods in rural western kenya the identification strategy relies on the stable historically determined patterns of ethnic land settlement ethnic diversity is associated with lower primary school funding and worse school facilities and there is suggestive evidence that it leads to poor water well maintenance the theoretical model illustrates how inability to impose social sanctions in diverse communities leads to collective action failures and we find that school committees in diverse areas do impose fewer sanctions on defaulting parents we relate these results to the literature on social capital and economic development and discuss implications for decentralization in less developed countries

internal borders ethnic based market segmentation in malawi summary ethnic diversity is associated with poorer economic development but why i argue that market segmentation is one mechanism linking diversity to economic underdevelopment when ethnic groups are geographically segregated and trust is concentrated within groups markets will be tend to be segmented along ethnic lines i evaluate this argument using maize price data from seventy malawian markets over 14 years and combine it with census data on the spatial distribution of ethnic groups i find that maize price differences a key indicator of market segmentation are indeed larger for ethnically dissimilar markets even after taking sub national administrative borders geographic barriers and climatic differences into account these statistical findings are complemented by interview data from farmers and traders in three markets across malawi which highlight the centrality of trust in small scale maize trading as well as a preference for coethnic trading partners together these findings suggest that ethnic diversity and ethnoregional segregation in particular can have a negative impact on market integration an important driver of food security and long term economic development

community composition and collective action analyzing initial mail response to the 2000 census this paper analyzes how community heterogeneity influences resident decisions to undertake actions generating public benefits the decision in question is completing and returning the 2000 census questionnaire an action which secures a significant amount of federal grants for the community the model developed to explain this action allows members of societal groups to differentially value public benefits that accrue to other group members racial generational and socioeconomic class heterogeneity all predict significantly lower response rates at the county level the potential for endogenous sorting into heterogeneous counties implies that the magnitude of true behavioral effects exceeds these estimates

food security and storage in the middle east and north africa in times of highly volatile commodity markets governments often try to protect their populations from rapidly rising food prices which can be particularly harsh for the poor a potential solution for food deficit countries is to hold strategic reserves which can be called on when international prices spike but how large should strategic stockpiles be this paper develops a dynamic storage model for wheat in the middle east and north africa mena region where imported wheat dominates the average diet the paper uses the model to analyze a strategy that sets aside wheat stockpiles which can be used when needed to keep domestic prices below a targeted price this paper shows that if the target is set high and reserves are adequate the strategy can be effective and robust contrary to most interventions strategic storage policies are counter cyclical and when the importing region is sufficiently large a regional policy can smooth global prices this paper shows that this is the case for the mena region nevertheless the policy is more costly than the pro cyclical policy of a targeted intervention that directly offsets high prices with a subsidy similar to food stamps

eliciting and utilizing willingness to pay evidence from field trials in northern ghana we utilize the becker degroot marschak 1964 mechanism to estimate the willingness to pay for clean drinking water technology in northern ghana the bdm mechanism has attractive properties for empirical research allowing us to directly estimate demand compute heterogeneous treatment effects and study the screening and causal effects of prices with minor modifications to a standard field experiment setting we demonstrate the implementation of bdm along these three dimensions compare it to the standard take it or leave it method for eliciting willingness to pay and discuss practical issues for implementing the mechanism in true field settings jel classifications c93 d12 d82 l11 l31

ethnic segregation and public goods evidence from indonesia this article contributes to the study of ethnic diversity and public goods provision by assessing the role of the spatial distribution of ethnic groups through a new theory that we call spatial interdependence we argue that the segregation of ethnic groups can reduce or even neutralize the diversity penalty in public goods provision that results from ethnic fractionalization this is because local segregation allows communities to use disparities in the level of public goods compared with other communities as leverage when advocating for more public goods for themselves thereby ratcheting up the level of public goods across communities we test this prediction on highly disaggregated data from indonesia and find strong support that controlling for ethnic fractionalization segregated communities have higher levels of public goods this has an important and underexplored implication decentralization disadvantages integrated communities vis a vis their more segregated counterparts

the food stamp program and food insufficiency food stamp participants have higher food insufficiency rates than eligible nonparticipants even after controlling for other factors given the food stamp program s prominent role in the alleviation of hunger this is a counterintuitive result we conjecture that these higher rates are due to adverse selection insofar as households more likely to be food insufficient are also more likely to receive food stamps we establish a theoretical framework to address this adverse selection using a simultaneous equation model with two probits we show that once one controls for this adverse selection food stamp recipients have the same probability of food insufficiency as nonrecipients copyright 2001 oxford university press

the long term effects of africa s slave trades can part of africa s current underdevelopment be explained by its slave trades to explore this question i use data from shipping records and historical documents reporting slave ethnicities to construct estimates of the number of slaves exported from each country during africa s slave trades i find a robust negative relationship between the number of slaves exported from a country and current economic performance to better understand if the relationship is causal i examine the historical evidence on selection into the slave trades and use instrumental variables together the evidence suggests that the slave trades have had an adverse effect on economic development

village elections public goods investments and pork barrel politics chinese style a key issue in political economy concerns the accountability that governance structures impose on public officials and how elections and representative democracy influence the allocation of public resources in this paper we utilise a unique set of survey data set from nearly 2450 randomly selected villages describing china s recent progress in village governance reforms and its relationship to the provision of public goods in rural china between 1998 and 2004 two sets of questions are investigated using an empirical framework based on a theoretical model in which local governments must decide to allocate fiscal resources between public goods investments and other expenditures the empirical analysis both in the descriptive and econometric analyses suggests that when the village leader is elected directly ceteris paribus the provision of public goods rises compared to when the leader is not elected directly by villagers thus in this way it is possible to conclude that democratisation at least at the village level in rural china appears to increase the quantity of public goods investment second we seek to understand the mechanism that is driving the results also based on the survey data we find that when village leaders who had been directly elected were able to implement more public projects during their terms of office they as the incumbent were more likely to be re elected in this way we argue that the link between elections and investment may be a rural china version of pork barrel politics

participatory accountability and collective action experimental evidence from albania it has been argued that accountability is a public good that only citizens can provide governments can put institutions in place that allow citizens to hold public servants to account but citizens must participate in those institutions if accountability is to be achieved thus citizens face a social dilemma participate in holding public servants to account at a cost in terms of time and effort or free ride i e do not participate while benefiting from the efforts of those who do if this characterization of accountability is valid we would expect more cooperatively inclined citizens to participate in accountability institutions while the less cooperatively inclined do not we test the validity of this characterization by investigating the correlation between individual behavior in a simple public goods game and their participation in local and national accountability institutions in albania we involve a nationally representative sample of 1800 adults with children in primary school we find significant correlations between cooperativeness and participation in school accountability institutions and national elections both at the individual level and the district level these correlations are robust to the introduction of many controls in the analysis and in the case of national elections to the use of official election turn out statistics in place of self reported turn out

on the use of instrumental variables in accounting research abstract instrumental variable iv methods are commonly used in accounting research e g earnings management corporate governance executive compensation and disclosure research when the regressor variables are endogenous while iv estimation is the standard textbook solution to mitigating endogeneity problems the appropriateness of iv methods in typical accounting research settings is not obvious drawing on recent advances in statistics and econometrics we identify conditions under which iv methods are preferred to ols estimates and propose a series of tests for research studies employing iv methods we illustrate these ideas by examining the relation between corporate disclosure and the cost of capital

exploring gendered behavior in the field with experiments why public goods are provided by women in a nairobi slum abstract women and particularly women in all female groups appear to be especially adept at providing public goods in developing countries we use a one shot public goods game to explore the effect of sex and a group s sex composition on the voluntary provision of public goods in a nairobi slum sex heterogeneity hurts the voluntary provision of public goods because women but not men contribute less in mixed sex than same sex groups women contribute as much as men in same sex groups this result is driven by women s pessimism and men s optimism about others contributions in mixed sex groups rather than by gendered social preferences

between group contests over group specific public goods with within group fragmentation we model a contest between two groups of equal sized populations over the division of a group specific public good each group is fragmented into subgroups each subgroup allocates effort between production and contestation perfect coordination is assumed within subgroups but subgroups cannot coordinate with one another all subgroups choose effort allocations simultaneously we find that the group that is more internally fragmented receives the smaller share of the public good aggregate rent seeking increases when the dominant subgroups within both communities have larger population shares any unilateral increase in fragmentation within a group reduces conflict and increases the total income of its opponent strikingly the fragmenting community itself may however increase its total income as well even though its share of the public good declines hence a smaller share of public good provisioning cannot be used to infer a negative income effect on the losing community

us and them the origin of identity and its economic implications we investigate the origins of identity and the innate proclivity to draw a distinction between insiders and outsiders we propose an evolutionary explanation we argue that identity arises because it facilitates survival in an evolutionary setting we endogenize preferences and demonstrate that the evolutionarily stable preferences fashioned by natural selection would draw a distinction between insiders and outsiders we then work out the implications of such preferences in two contemporary scenarios one entailing rent seeking behavior and the other involving public good provision our results are in conformity with empirical evidence

tribe or nation nation building and public goods in kenya versus tanzania this article examines how government policies affect ethnic relations by comparing outcomes across two nearby districts one in kenya and one in tanzania using colonial era boundary placement as a natural experiment despite similar geography and historical legacies governments in kenya and tanzania have followed radically different language education and local institutional policies with tanzania consistently pursuing more serious nation building the evidence suggests that nation building has allowed diverse communities in rural tanzania to achieve considerably better local public goods outcomes than diverse communities in kenya to illustrate while kenyan communities at mean levels of diversity have 25 percent less local school funding than homogeneous communities on average the comparable figure in the tanzanian district is near zero the kenya tanzania comparison provides empirical evidence that serious reforms can ameliorate social divisions and suggests that nation building should take a place on policy agendas especially in africa

collective action and the group size paradox according to the olson paradox larger groups may be less successful than smaller groups in furthering their interests we address the issue in a model with three distinctive features explicit intergroup interaction collective prizes with a varying mix of public and private characteristics and nonlinear lobbying costs the interplay of these features leads to new results when the cost of lobbying has the elasticity of a quadratic function or higher larger groups are more effective no matter how private the prize with smaller elasticities a threshold degree of publicness is enough to overturn the olson argument and this threshold tends to zero as the elasticity approaches the value for a quadratic function we also demonstrate that these results are true irrespective of whether we examine group sizes over the cross section in some given equilibrium or changes in the size of a given group over different equilibria

decentralization and pollution spillovers evidence from the re drawing of county borders in brazil decentralization can improve service delivery but it can also generate externalities across jurisdictional boundaries we examine the nature and size of water pollution externalities as rivers flow across jurisdictions panel data on water pollution in brazilian rivers coupled with county splits that change the locations of borders allow us to identify the spatial patterns of pollution as rivers approach and cross borders controlling for fixed effects and trends specific to each location the theory of externalities predicts that pollution should increase at an increasing rate as the river approaches the downstream exit border that there should be a structural break in the slope of the pollution function at the border and that a larger number of managing jurisdictions should exacerbate pollution externalities we find support for all four predictions in the data satellite data on growth in night time lights along rivers show that local authorities allow more settlements to develop close to rivers in the downstream portions of counties which is the likely underlying mechanism the border effects on pollution are not as pronounced when the cost of inter jurisdictional coordination is lower

free riding and ethnic heterogeneity abstract this paper provides a new explanation for lower levels of public good provision in heterogeneous societies compared to their homogeneous counterparts social sharing norms force rich individuals to share part of their income with their poor relatives but do not apply across different ethnic groups because there is a more extensive redistribution in more homogeneous societies the cost of contributing to the public good is lower the model predicts the level of public goods provision and welfare monotonically decreases with the number of different ethnic groups

the impact of food stamp program participation on household food insecurity this study examines the impact that participation in the food stamp program has on household food insecurity using data from the panel survey of income dynamics two strategies are used to identify the causal effect of the program first endogenous treatment effect models are estimated using state level errors in payments of benefits as instruments additionally the impact of losing benefits due to a government decision on the food insecurity of program participants is examined the paper finds that program participation lowers food insecurity by at least 18

vice or virtue the impact of corporate social responsibility on executive compensation we empirically examine the impact of corporate social responsibility csr on ceo compensation using a large sample of the us firms from 1996 to 2010 we develop and test two hypotheses the overinvestment hypothesis based on agency theory and the conflict resolution hypothesis based on stakeholder theory we find that the lag of csr adversely affects both total compensation and cash compensation after controlling for various firm and board characteristics our estimates show that an interquartile increase in csr is followed by a 4 35 2 78 decrease in total cash compensation we also find an inverse association between lagged employee relations and ceo compensation our results are robust to the correction for endogeneity using instrumental variable approach taken together our results support the conflict resolution hypothesis but not the csr overinvestment argument

can social cohesion be harnessed to repair market failures evidence from group lending in guatemala the success of group lending in developing countries has been attributed to the ability of the institution to mitigate asymmetric information problems in credit markets previous research has offered a number of explanations for this phenomenon social ties between borrowing group members internal group pressure to repay loans and peer monitoring this research presents empirical tests on borrowing group data from guatemala which indicate that peer monitoring significantly effects borrowing group performance through stimulating intra group insurance group pressure is found to have a small effect in deterring moral hazard while the effect of social ties among members is statistically insignificant

executive compensation and tournament theory empirical tests on danish data this article adds to the empirical literature on tournament theory as a theory of executive compensation i test several propositions of tournament models on a rich data set containing information about 2 600 executives in 210 danish firms during a 4 year period i ask are pay differentials between job levels consistent with relative compensation is pay dispersion between levels higher in noisy environments is the dispersion affected by the number of tournament participants is average pay lower in firms with more compressed pay structures does wider pay dispersion enhance firm performance most of the predictions gain support in the data

explaining african economic performance africa has had slow growth and a massive exodus of capital in many respects it has been the most capital hostile region we review and interpret the aggregate level and microeconomic literatures to identify the key explanations for this performance there is a reasonable correspondence of the two sets of evidence pointing to four factors as being important these are a lack of openness to international trade a high risk environment a low level of social capital and poor infrastructure these problems are to a substantial extent attributable to government behaviour and the paper includes a review of the political economy literature which addresses that behaviour

the cost of segregation in social networks abstract this paper investigates the welfare effect of income redistribution in the private provision of public goods on networks we first show that the welfare effect of income redistribution is determined by bonacich centrality then we develop an index based on the network structure of interactions which roughly speaking measures the welfare effect of income redistribution confined to a component of contributors the proposed index vanishes when applied to large components of contributors that display special segregated interactions which suggests an asymptotic neutrality of redistributive policies

leadership and the voluntary provision of public goods field evidence from bolivia abstract we conduct a controlled field experiment in 52 communities in rural bolivia to investigate the effect that local authorities have on voluntary public good provision in our study community members pool resources to provide environmental education material for local schools we find that voluntary contributions increase when democratically elected local authorities lead by example the results are driven by two factors 1 authorities like other individuals give more when they are called upon to lead than when they give in private and 2 high leader contributions increase the likelihood that others follow both effects are stronger when authorities as compared to randomly selected community members lead by example we explore two underlying sources of leadership influence first we provide evidence that the effect of a leader s contribution is not limited to signaling the value of the public good second we examine how leader characteristics affect the likelihood that others follow specifically our study shows that authority influence is driven by a combination of formal leadership status observable characteristics and the amount that authorities contribute when they give publicly before others

do formula based intergovernmental transfer mechanisms eliminate politically motivated targeting evidence from ghana abstract various countries have adopted formulas for determining intergovernmental transfers as a strategy to limit the role of political considerations in resource allocation in this paper we investigate a formula based system of allocating resources from a central government to local governments to determine whether the political characteristics of recipient areas have any bearing on their allocation specifically we study the sharing of resources of the district assemblies common fund dacf in ghana amongst the country s district governments over the period 1994 to 2005 we find evidence that the mechanism does not eliminate politically motivated targeting of the grants per capita dacf grants were higher in districts where vote margins in the previous presidential election were lower suggesting that swing districts were targeted we find evidence that dacf formula indicators and their weighting were chosen and amended to produce politically desired patterns of transfers

it s the market the broad based rise in the return to top talent abstract one explanation that has been proposed for rising inequality is that technical change allows highly talented individuals or superstars to manage or perform on a larger scale applying their talent to greater pools of resources and reaching larger numbers of people thus becoming more productive and higher paid others argue that managerial power has increased in a way that allows those at the top to receive higher pay that social norms against higher pay levels have broken down or that tax policy affects the distribution of surpluses between employers and employees we offer evidence bearing on the different theories explaining the rise in inequality in the united states over recent decades first we look the increase in pay at the highest income levels across occupations we consider the income share of the top 1 percent over time and we turn to evidence on inequality of wealth at the top in looking at the wealthiest americans we find that those in the forbes 400 are less likely to have
