deposit guarantee evaluation and incentives analysis in a mutual guarantee system abstract this paper analyzes how the deposit guarantee value affects the risk incentives in a mutual guarantee system we liken the guarantee s value to that of a european style contingent claims portfolio the main feature emerging from our model is that a mutual guarantee system would give banks an adverse incentive to increase riskiness to mitigate this incentive we introduce a regulatory provision modelled using a path dependent contingent claim by comparing the mutual guarantee system with a non mutual one we show that the former is less expensive but implies higher adverse incentives for the banks especially for undercapitalized institutions

repudiation risk and restitution costs toward understanding premiums on insured deposits this paper contains a theoretical development of the relationship of cd premiums to both the risks of the cd issuer and the third party government guarantor of those deposits the theoretical development shows that the risk of the guarantor derives from the possibility that the guarantee could be repudiated and or the restitution of the depositor s claim could be costly the empirical analysis of the premiums for insured cds indicates that during the years preceding the ultimate collapse of the fslic the market priced the risk of both the guarantor as well as the firm the guarantor risk pricing was responsive to the insolvency of the guarantor the attempts to recapitalize the guarantor and the efforts to resolve the insolvent thrifts during this eventful time period cd premiums rose to 187 basis points and averaged 79 and 54 basis points copyright 1994 by ohio state university press

income inequality capitalism and ethno linguistic fractionalization we examine the relationship between capitalism and income inequality for a large sample of countries using an adjusted economic freedom index as proxy for capitalism our results suggest that there is no robust relationship between economic freedom and gini coefficients based on gross income subsequently we analyze the relationship between income redistribution and ethno linguistic fractionalization we find that the impact of ethno linguistic fractionalization on income redistribution is conditional on the level of economic freedom countries that have a high degree of fractionalization redistribute income less while capitalist countries that have a low degree of fractionalization redistribute income more

evidence on growth increasing returns and the extent of the market if economic growth relies upon the extent of the market then openness will decrease the connection between initial income and later growth alternatively learning by doing models suggest that wealth will be more positively correlated with growth in open economies because trade causes advanced economies to specialize in products with more opportunities for learning we examine twentieth century less developed countries and nineteenth century u s states in both data sets there is a much stronger correlation between growth and initial wealth among closed economies these findings support the importance of the extent of the market and aggregate demand in fostering growth

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

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

does deposit insurance retard the development of non bank financial markets whether and how the introduction of deposit insurance affects non bank financial market development depends on whether banks and non bank financial markets are substitutes or complements and theory has conflicting views using data on 134 countries over a 28 year period and several identification strategies we find that the introduction of deposit insurance retards the equity market the non bank depositaries sector and the banking sector when law and order is weak while strong law and order mitigates this effect it does not lead to a positive outcome for all markets for non bank financial markets the effect is greater in the long run so that while deposit insurance increases banking sector development in the long run it retards non bank financial markets regardless of the level of law and order finally several design features exacerbate the negative outcomes our results have important policy implications for implementing or altering deposit insurance schemes

the political economy of linguistic cleavages article i nfo this paper uses a linguistic tree describing the genealogical relationship between all 6912 world languages to compute measures of diversity at different levels of linguistic aggregation by doing so we let the data inform us on which linguistic cleavages are most relevant for a range of political economy outcomes rather than making ad hoc choices we find that deep cleavages originating thousands of years ago lead to better predictors of civil conflict and redistribution the opposite pattern emerges when it comes to the impact of linguistic diversity on growth and public goods provision where finer distinctions between languages matter 2011 elsevier b v all rights reserved

group loyalty and the taste for redistribution interpersonal preferences preferences that depend on the characteristics of others are typically hard to infer from observable individual behavior as an alternative approach this paper uses survey data to investigate interpersonal preferences i show that self reported attitudes toward welfare spending are determined not only by financial self interest but also by interpersonal preferences these interpersonal preferences are characterized by a negative exposure effect individuals decrease their support for welfare as the welfare recipiency rate in their community rises and racial group loyalty individuals increase their support for welfare spending as the share of local recipients from their own racial group rises these findings help to explain why levels of welfare benefits are relatively low in racially heterogeneous states

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

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

returns from research in economies with policy distortions hybrid sorghum in sudan conventional estimates of the economic return to agricultural research use market prices for the values of products and inputs on this basis economic rates of return are typically well above the cost of capital suggesting that more investment in research would be socially desirable but these estimates may be incorrect if as is often the case market prices are distorted by market failures or government policies and hence do not reflect social values this paper presents a simple partial equilibrium methodology with which to improve the measurement of social returns to research by taking account of multiple distortions in the market prices of products inputs and foreign exchange the method also takes account of variation in domestic and world prices making a product tradable in some years and nontradable in others the method is applied to the case of hageen dura 1 hd 1 sub saharan africa s first commercially successful hybrid sorghum hd 1 was released in the sudan in 1983 from the start of research in 1979 to 1992 the hd 1 breeding program had an estimated irr of 97 when all major policies in the sorghum market the fertilizer market and the exchange rate are taken into account the high rate of return to hd 1 research was due to the program s low cost and rapid payoff pointing to the potential value of small adaptive research programs taking full advantage of foreign technology and genetic material to produce locally appropriate crosses in a short period of time even in the highly distorted economies of africa such programs can yield very high payoffs

do depositors punish banks for bad behavior market discipline deposit insurance and banking crises this paper empirically investigates two issues largely unexplored by the literature on market discipline we evaluate the interaction between market discipline and deposit insurance and the impact of banking crises on market discipline we focus on the experiences of argentina chile and mexico during the 1980s and 1990s we find that depositors discipline banks by withdrawing deposits and by requiring higher interest rates deposit insurance does not appear to diminish the extent of market discipline aggregate shocks affect deposits and interest rates during crises regardless of bank fundamentals and investors responsiveness to bank risk taking increases in the aftermath of crises

the openness equality trade off in global redistribution the gulf cooperation council gcc countries accept massive numbers of migrants from poor countries and pay wages that dramatically improve over outside options but are meagre by the standards of natives as such they do dramatically more per capita to reduce global inequality than do the fortress welfare states of the organisation for economic cooperation and development oecd countries if oecd countries were to imitate the gcc it would reduce global inequality by more than full equalisation within the oecd would such examples suggest a philosophically disturbing trade off between openness to global inequality reducing migration and internal equality

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

extending the concept of the resource curse natural resources and public spending on health this paper extends the concept of the resource curse by studying whether and through which transmission channels natural resource wealth affects social spending even though the availability of vast natural capital reserves has commonly been linked to the neglect of human development most of the literature has continued to focus on economic performance this paper is the first to empirically investigate the link between natural resource wealth and public health expenditures in light of the hypothesis that resource wealth as a source of unearned state income enhances state autonomy and increases volatility which leads to policies that fail to prioritize human development using a large panel dataset of world countries covering the period from 1995 to 2009 we find a robust significant inverse relationship between natural resource dependence and even abundance and public health spending over time the effect remains significant after controlling for state autonomy volatility and other factors these findings have implications for national authorities as well as the extractive industry governments should be made accountable for natural resource wealth and correct taxation could provide additional resources earmarked for health the extractive industry could increase their investments in sustainable corporate social responsibility operations specifically in the health sector

market discipline and deposit insurance reform in japan abstract on april 1 2002 the japanese government lifted a blanket guarantee of all deposits and began limiting the coverage of time deposits this paper uses this deposit insurance reform as a natural experiment to investigate the relationship between deposit insurance coverage and market discipline i find that the reform raised the sensitivity of interest rates on deposits and that of deposit quantity to default risk in addition the interest rate differentials between partially insured large time deposits and fully insured ordinary deposits increased for risky banks these results suggest that the deposit insurance reform enhanced market discipline in japan i also find however that too big to fail tbtf policy became a more important determinant of interest rates and deposit allocation after the reform thereby partially offsetting the positive effects of the deposit insurance reform on overall market discipline

language group differences in time preferences evidence from primary school children in a bilingual city abstract we study differences in intertemporal choices across language groups in an incentivized experiment with 1154 children in a bilingual city the sample consists of 86 of all primary school kids in meran merano where about half of the 38 000 inhabitants speak german and the other half italian while both language groups live very close to each other we find that german speaking primary school children are about 16 percentage points more likely than italian speaking children to delay gratification in an intertemporal choice experiment the difference remains significant in several robustness checks and when controlling for a broad range of factors including risk attitudes iq family background or residential area hence we are able to show that language group affiliation which is often used as a proxy for culture plays an important role in shaping economic preferences already early in life

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

does deposit insurance increase banking system stability an empirical investigation based on evidence of 61 countries in 1980 97 the authors find that explicit deposit insurance tends to be detrimental to bank stability the more so where bank interest rates are deregulated and the institutional environment is weak the adverse impact of deposit insurance on bank stability tends to be stronger the more extensive is the coverage offered to depositors and where the scheme is funded and run by the government rather than the private sector

holding on ethnic divisions political institutions and the duration of economic declines abstract we analyze the duration of large economic declines and provide a theory of delayed recovery we show theoretically that uncertain post recovery incomes lead to a commitment problem which limits the possibility of cooperation in ethnically heterogeneous countries strong constraints on the executive solve this problem by reducing the uncertainty associated with cooperative behavior we test the model using standard data on linguistic heterogeneity and detailed data on ethnic power configurations our findings support the central theoretical prediction countries with more constrained political executives experience shorter economic declines the effect is large in ethnically heterogeneous countries but virtually non existent in homogeneous societies our main results are robust to a variety of perturbations regarding the estimation method the estimation sample measures of heterogeneity and measures of institutions

deposit insurance regulation and moral hazard in the thrift industry evidence from the 1930 s this paper compares risk taking of insured and uninsured thrifts operating under strict and less strict regulatory regimes during the 1930 s analysis of balance sheet data indicates that while newly insured thrifts undertook less risk than their uninsured counterparts possibly because of screening by deposit insurance authorities moral hazard emerged gradually insured institutions operating under relatively permissive regulatory regimes were more prone to undertake risky lending activities than their more tightly regulated counterparts possibly because of screening by deposit insurance authorities moral hazard emerged gradually insured institutions operating under relatively premissive regulatory regimes were more prone to undertake risky lending activities than their more tightly regulated counterparts given the current system of deposit insurance the results suggest that effective regulation and supervision will play a key role in maintaining thrift stability in the 1990s copyright 1992 by american economic association

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

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

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

history social divisions and public goods in rural india we examine the influence of three historically important sources of social divisions on the availability of public goods in rural india colonial power landowner peasant relations as determined by the land tenure system and social fragmentation based on the hindu caste system and the presence of sizable religious minorities using data on public goods from 1991 we find that regions that were under british colonial power in the pre independence period and those where agrarian power was concentrated in the hands of landlords have lower access to these goods as do areas with high levels of social fragmentation jel h41 p16

fractionalization entrepreneurship and the institutional environment for entrepreneurship the vast majority of the literature on ethnicity and entrepreneurship focuses on the construct of ethnic entrepreneurship however very little is known about how ethnic heterogeneity affects entrepreneurship and the institutional arrangements affecting entrepreneurship this study attempts to fill the gap and thus examines the effect of ethnic heterogeneity on various outcomes associated with entrepreneurship and the institutional environment for entrepreneurship using indices of ethnic and linguistic fractionalization we show that ethnic heterogeneity negatively influences entrepreneurship we argue that potential channels that can explain the negative effect of fractionalization on entrepreneurship include trust social network and innovation among others this study provides a new perspective on the existing debate that seeks to understand why the levels of entrepreneurial success vary across countries

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 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

impacts of food crop improvement research evidence from sub saharan africa abstract the paper reviews and summarizes evidences of impacts of crop improvement research of major food crops in africa it provides evidence of increased availability of improved varieties of major food crops to farmers in africa increased food production in regions where adoption has occurred and positive returns to research investment indicating that agricultural research in africa has had productivity increasing impacts on its agriculture however research impacts vary considerably across countries and regions within a country as a result of agroclimatic factors and policy environment which affects the supply of seeds and other inputs and the continuity and stability of research investments the paper points to a number of important issues both internal and external to the agricultural research system organization that need to be addressed if agricultural research is to provide a stimulus for modernizing african agriculture given the small size of food crop production area in many african countries it is important for research systems to take full advantage of research spill ins from regional and international research organizations there is a great potential to increase the efficiency of research systems by improving the coordination among members of national research systems and continuing improvements in collaborations between narss and regional and international organizations

economics of biological control of cassava mealybug in africa abstract pest populations of the cassava mealybug phenacoccus manihoti mat ferr homoptera pseudococcidae were reduced successfully by the biological control agent apoanagyrus epidinocarsis lopezi de santis hymenoptera encyrtidae throughout most of sub saharan africa the economics of the project were evaluated based on data from field trials socio economic surveys published results and financial information provided by the international institute of tropical agriculture iita and the national programmes costs and benefits for the biological control of p manihoti were calculated over 40 years 1974 2013 for 27 african countries for four different scenarios taking into account that impact by a lopezi and speed of the impact differ between ecological zones a reasonable calculation considering compounded interest resulted in a benefit cost ratio of about 200 when cassava was costed at world market prices and of about 370 740 when inter african prices were considered

using market information in prudential bank supervision a review of the u s empirical evidence in principle market and government supervision provide alternative devices for controlling governing any type of corporation most national governments have instituted nonmarket regulatory mechanisms for banking firms on the grounds that market based mechanisms do not adequately discipline banks but what evidence supports this assessment why must governments assure bank solvency but not the solvency of other firms government oversight naturally displaces private efforts to evaluate and control financial firms moreover if the banking business changes over time as it assuredly has in the past decade or two the best combination of government and private supervision may change concurrently this paper reviews and evaluates the growing empirical literature on private investors abilities to assess the financial condition of banking firms the evidence supports the proposition that market investors and analysts could reasonably provide a greater proportion of corporate governance services for large traded u s financial firms

economic integration and political disintegration in a world of trade restrictions large countries enjoy economic benefits because political boundaries determine the size of the market under free trade and global markets even relatively small cultural linguistic or ethnic groups can benefit from forming small homogeneous political jurisdictions this paper provides a formal model of the relationship between openness and the equilibrium number and size of countries and successfully tests two implications of the model firstly the economic benefits of country size are mediated by the degree of openness to trade secondly the history of nation state creations and secessions is influenced by the trade regime

ethnicity and conflict an empirical study this paper examines the impact of ethnic divisions on conict the empirical specication is informed by a theoretical model of conict esteban and ray 2011 in which equilibrium conict is related to just three distributional indices of diversity ethnic polarization ethnic fractionalization and a greenberg gini index constructed across ethnic groups our empirical ndings verify that these distributional measures are signicant correlates of conict the underlying theory permits us to use these results to make inferences about the relative importance of public goods in conict as well as the extent of within group cohesion in conictual activity these eects are further strengthened as we introduce country specic measures of group cohesion and the relative importance of public goods and combine them with the distributional measures exactly as specied by the theory

language and the theory of the firm we characterize efficient technical languages and study their interaction with the scope and structure of organizations efficient languages use precise words for frequent events and vague words for unusual ones a broader organizational scope allows for more synergies to be captured but reduces within unit efficiency since it requires a more generic language a manager working as specialized translator may also be used to achieve between unit coordination while maintaining separate languages our theory reconciles two recent well documented phenomena within organizations the recent increase in information centralization and the reduction in hierarchical centralization

disagreement and learning about reforms when it comes to economic reforms in developing countries many economists agree on broad objectives broad objectives however can be pursued in different ways and policy experimentation is often indispensable for learning which alternative works locally we propose a theoretical model to study this societal learning process the model explores the role of disagreeing beliefs about what works it suggests that such disagreement can stall the societal learning process and cause economic stagnation although everyone knows that growth promoting reforms do exist our analysis is motivated by the observation of a negative relationship between disagreement and economic growth among poorer countries

which banks choose deposit insurance evidence of adverse selection and moral hazard in a voluntary insurance system this article investigates adverse selection and moral hazard in the voluntary deposit insurance system of kansas which operated from 1909 to 1929 regulations were imposed to limit risk taking and membership was made voluntary to assuage objections that insurance forces conservative banks to protect depositors of high risk institutions the authors find however that risk prone banks were the most likely to join the system at its inception using a simultaneous equations model they also detect both adverse selection and moral hazard behavior throughout the system s first ten years copyright 1995 by ohio state university press

does a cassava research for development program have impact at the farm level evidence from the democratic republic of congo this paper evaluates the impact of a cassava research for development program on farm level outcomes the program was implemented in the democratic republic of congo from 2001 to 2009 we apply propensity score matching rosenbaum bounds on treatment effects altonji et al method of selection on observables and unobservables and endogenous switching regression to farm survey data collected during the 2009 cropping season we use these methods to test whether the r4d program has a statistically significant effect on outcomes of interest and if these are not driven by selection on unobservables using propensity score matching we find statistically significant positive effects on household participation in cassava markets adoption of improved varieties and crop management practices and household food adequacy and no statistically significant effects on yields and profits the results show that bias due to selection on unobservables is not severe enough to invalidate the impact estimates bias may still be a problem that is present in the analysis but there is evidence that it is not substantial although the program does not have a statistically significant positive effect on yields and profits the significant program effects on market participation variety adoption and food adequacy merit further promotion of the program since these positive outcomes tend to be pre conditions for realizing long term yield and profit benefits

too dispersed to monitor ownership dispersion monitoring and the prediction of bank distress this paper conducts an empirical assessment of the theories stating that ownership concentration improves the quality of shareholders monitoring in contrast with other studies we do not use regressions of risk performance on ownership concentration instead we build an early warning model of bank distress that includes a leading indicator derived from banks share price the merton kmv distance to default dd the significance of this indicator depends on the efficacy of shareholders monitoring on a sample of european banks we show that the predictive power of the dd is satisfactory only when banks shareholding is characterized by the presence of blockholders

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

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

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

cultural diversity and economic growth evidence from the us during the age of mass migration we exploit the large inflow of immigrants to the us during the 1870 1920 period to examine the effects that within county changes in the cultural composition of the us population had on output growth we construct measures of fractionalization and polarization to distinguish between the different effects of cultural diversity our main finding is that increases in cultural fractionalization significantly increased output while increases in cultural polarization significantly decreased output we address the issue of identifying the causal effects of cultural diversity by using the supply push component of immigrant inflows as an instrumental variable

value diversity and regional economic development we investigate the link between culture and regional economic development within european countries considering a variety of cultural values we provide evidence that it is the degree of diversity in these values at the regional level that strongly correlates with economic performance rather than the prevalence of specific values in particular we show that greater value diversity is negatively associated with regional economic performance within countries which also relates to lower institutional quality and poorer public goods provision these patterns are robust even when diversity is measured based on values expressed by emigrants residing outside of their region of origin this article is protected by copyright all rights reserved

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

on the determinants of political polarization in this article we aim to identify the main determinants of political polarization using bayesian model averaging to overcome the problem of model uncertainty we find that the level of trust within a country and the degree of income inequality are the most robust determinants of political polarization

political influence and declarations of bank insolvency in japan this paper investigates how politics affects bank supervision by examining determinants of bank failures in japan during 1999 2002 a period during which bank regulators were called upon to resolve insolvent banks in preparation for the lifting of a blanket deposit guarantee the empirical results suggest that japan s bank regulators had tendency to delay declarations of insolvency in prefectures that supported senior politicians of the ruling liberal democratic party ldp this result which is robust to a host of bank level and prefecture level controls suggests that bank supervision is prone to political influence that delays efficient resolution of insolvency

the fiscal cost implications of an accommodating approach to banking crises abstract in recent decades a majority of countries have experienced a systemic banking crisis requiring a major and expensive overhaul of their banking system budgetary outlays whether immediate or deferred have exceeded 50 of gdp in some cases this paper uses cross country econometric evidence to examine whether the design of crisis containment and resolution policies can systematically influence the overall magnitude of fiscal costs we find that accommodating policies such as blanket deposit guarantees open ended liquidity support repeated partial recapitalizations debtor bail outs and regulatory forbearance all tend to add significantly and sizably to fiscal costs

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

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 effect of language training on immigrants economic integration empirical evidence from france abstract we examine the impact of language training on the economic integration of immigrants in france the assignment to this training offered by the french ministry of the interior depends mainly on a precise rule the training is provided if the test score of an initial language exam is below a certain threshold this eligibility rule creates a discontinuity in the relation between the test result and the variables of interest which is used to estimate the causal effect of language training through the method of regression discontinuity design we find that the number of assigned hours of training significantly increases labor force participation of the treated individuals the language classes appear to have a larger effect for individuals with higher levels of education while there is no robust differential effect by type of migration gender or age our estimated coefficients are remarkably similar when we rely on local linear regressions using the optimal bandwidth with few observations around the threshold and when we control parametrically for a polynomial of the forcing variable and use the whole estimation sample we conclude with a discussion of the candidate mechanisms for the improved labor market participation of immigrants

do weak institutions prolong crises on the identification characteristics and duration of declines during economic slumps this paper studies periods of prolonged contractions in output per capita in a sample of 145 countries from 1950 to 2014 economic slumps are defined as abrupt interruptions of a period of growth by several regime switches slumps start with a sharp contraction along with a trend break which is followed by another switch when growth stabilizes again the paper then analyzes the correlates of these slumps focusing on the length and depth of the contraction from the beginning of the slump to its trough the results establish three new stylized facts i weak political institutions predate crises whereas political reforms tend to follow them ii the length and depth of economic declines are robustly correlated with executive constraints and ethnic heterogeneity and iii there is a robust interaction between these two variables suggesting that institutions constraining leaders are important for stabilizing growth this is particularly relevant for sub saharan africa where politics are often ethnic and decision makers are comparatively unconstrained

genetic diversity and the origins of cultural fragmentation despite the importance attributed to the effects of diversity on the stability and prosperity of nations the origins of the uneven distribution of ethnic and cultural fragmentation across countries have been underexplored building on the role of deeply rooted biogeographical forces in comparative development this research empirically demonstrates that genetic diversity predominantly determined during the prehistoric out of africa migration of humans is an underlying cause of various existing manifestations of ethnolinguistic heterogeneity further exploration of this uncharted territory may revolutionize the understanding of the effects of deeply rooted factors on economic development and the composition of human capital across the globe

building an incentive compatible safety net abstract bank safety nets originally proposed as a means of stabilizing financial systems have become an important destabilizing influence government protection of bank debts encourages banks to undertake excessive risk particularly in response to adverse shocks to asset values reforms that would remove the destabilizing moral hazard consequences of government protection are considered both from the perspective of economic desirability and political feasibility requiring banks to maintain a minimal proportion of subordinated debt finance and restricting the means by which government recapitalization of insolvent banks occurs are the central features of promising reforms to the safety net

should a team be homogeneous abstract should an organization hire people with similar backgrounds or with different backgrounds we formulate this question within the framework of team theory the team is formed by n agents the type of each agent is endogenous and determines his information structure and his cost for the team we show that the sign of complementarity between jobs determines workforce homogeneity with positive complementarities the team should be composed of agents of the same type while with negative complementarities workforce heterogeneity is optimal these results do not rely on the restrictions on the way uncertainty is modeled or on the feasible set of agent types they can be explained in terms of correlation between errors committed by different agents

explaining bank failures deposit insurance regulation and efficiency this paper uses micro level historical data to examine the causes of bank failure for state chartered kansas banks during 1910 28 time to failure is explicitly modeled using a proportional hazards framework in addition to standard financial ratios this study includes membership in the voluntary state deposit insurance system and a measure of technical efficiency to explain bank failure the results indicate that deposit insurance system membership increased the probability of failure and technically inefficient banks were more likely to fail than technically efficient banks copyright 1995 by mit press

unnatural selection perverse incentives and the misallocation of credit in japan we examine the misallocation of credit in japan associated with the perverse incentives faced by banks to provide additional credit to the weakest firms firms are more likely to receive additional bank credit if they arein poor financial condition because troubled japanese banks have an incentive to allocate credit to severely impaired borrowers in order to avoid the realization of losses on their own balance sheets this evergreening behavior is more prevalent among banks that have reported capital ratios close to the required minimum and is compounded by the incentives arising from extensive corporate affiliations

does the japanese stock market price bank risk evidence from financial firm failures the ability of the japanese stock market to appropriately price the riskiness of japanese financial firms has been frequently questioned particularly in light of japan s widespread financial distress in recent years and poor disclosure requirements this paper examines the response in equity returns of japanese banks to the failure of four commercial banks and two securities firms between 1995 and 1998 using event study methodology the analysis finds that share prices of surviving banks on the whole responded unfavorably to the failures and that financially weaker survivors were more adversely affected this suggests that despite the distress and alleged opaqueness bank shareholders were able to use available indicators of financial condition both to incorporate new information quickly into stock prices and to differentiate among banks

capital regulation and bank risk taking a note abstract this paper examines theoretically the effects of more stringent capital regulation on bank asset portfolio risk the analysis shows that for a value maximizing bank incentives to increase asset risk decline as its capital increases thus as long as regulatory efforts to contain asset risk and size are not reduced more stringent capital regulation unambiguously reduces the expected liability of the deposit insurance system

analysis of adoption and impacts of improved maize varieties in eastern zambia summary this paper analyzes the adoption and welfare impacts of improved maize varieties in eastern zambia using data obtained from a sample of over 800 farm households using both propensity score matching and endogenous switching regression models the paper shows that adoption of improved maize leads to significant gains in crop incomes consumption expenditure and food security results further show that improved maize varieties have significant poverty reducing impacts in eastern zambia the paper concludes with implications for policies to promote adoption and impacts of modern varieties in zambia

a yen is not a yen tibor libor and the determinants of the japan premium pricing in the euroyen market is based on libor the london interbank offered rate set at 11 00am london time or tibor the tokyo interbank offered rate set at 11 00am tokyo time the changing tibor libor spread reflects the credit risk associated with japanese banks or the japan premium the spread is modeled as a function of determinants of bank default and firm value systematic variation in the spread can be explained by interest rate and stock price effects along with public information flows of good and bad news regarding japanese banking with a separate role for bank credit downgrades and upgrades

integrated pest management for resource poor african farmers is the emperor naked abstract the success of integrated pest management ipm with rice in asia has not been replicated with staple smallholder food crops in sub saharan africa this is variously blamed on inadequate extension underinvestment in agricultural research and unfavorable government policies this article argues that it reflects the slow progress of africa s green revolution which has reduced economic incentives for chemical forms of crop protection and thus the potential cost savings from the adoption of ipm strategies in this context ipm must re think its approach ipm is more likely to be adopted by resource poor african farmers if it focuses on host plant resistance and biological control high value commodities and helps meet farmers wider objectives of increasing household food security and earning cash income the argument is illustrated from secondary literature and recent project experience in southern malawi

market discipline and deposit insurance cross country evidence presented in this paper suggests that explicit deposit insurance reduces required deposit interest rates while at the same time it lowers market discipline on bank risk taking internationally deposit insurance schemes vary widely in their coverage funding and management this reflects that there are widely differing views on how deposit insurance should optimally be structured to inform this debate we use a newly constructed data set of deposit insurance design features to examine how different design features affect deposit interest rates and market discipline

determinants of the japan premium actions speak louder than words abstract since august 1995 japanese banks have had to pay a premium on eurodollar and euroyen interbank loans relative to their u s and u k competitors this so called japan premium provides a market indicator of investor anxiety about the ability of japanese banks to repay loans we examine the determinants of the japan premium and find that government announcements not associated with concrete actions had little impact on the other hand announcements of concrete actions by the japanese government such as injections of funds into the banking system tended to have an effect on the size of the japan premium

estimating overall returns to international agricultural research in africa through benefit cost analysis a best evidence approach this study offers a best evidence approach to summarizing recent benefit cost analyses of international agricultural research in africa first from an extensive literature review and the resulting global inventory of impact studies 23 studies are identified that calculate aggregate rates of return for consultative group on international agricultural research cgiar and partner investments in sub saharan africa ssa these studies are then appraised against a review framework consisting of principles criteria and indicators for study rigor subsequently the economic benefits reported by studies grouped on the basis of its analytical rigor are aggregated and set against total investment by the cgiar and national agricultural research systems to determine if the total investment to date can be justified by documented benefits under a range of assumptions as a result the study finds that aggregate investment is justified under a fairly wide range of suppositions under all scenarios the vast majority of documented benefits stem from a relatively limited array of activities with a majority of benefits stemming from biological control 80 close to 20 of total benefits result from crop genetic improvement and less than 1 result from all other activities the implications of these results for research investment strategies in ssa and impact assessment are discussed

culture ethnicity and diversity we investigate the empirical relationship between ethnicity and culture defined as a vector of traits reflecting norms attitudes and preferences using surveys of individual values in 76 countries we find that ethnic identity is a significant predictor of cultural values yet that within group variation in culture trumps between group variation thus in contrast to a commonly held view ethnic and cultural diversity are unrelated we explore the correlates of cultural diversity and of the overlap between culture and ethnicity finding that the level of economic development is positively associated with cultural diversity and negatively associated with the overlap between culture and ethnicity finally although only a small portion of a country s overall cultural heterogeneity occurs between groups this does not imply that cultural differences between groups are irrelevant indeed we find that civil conflict becomes more likely when there is greater overlap between ethnicity and culture

deposit insurance and depositor discipline direct evidence on bank switching behaviour in japan as japan s financial system becomes more market oriented depositor discipline is playing a larger role in the monitoring of banks matching household survey data with banks financial data we examine households response to bank risk and different deposit insurance schemes we find that bank switching in response to risk increased between 1996 and 2001 and households choice of bank adequately reflects banks financial health we also examine the determinants of households knowledge of the deposit insurance scheme and how this affects switching behaviour the results suggest that depositor discipline works and could play an important supplementary role in bank monitoring
