learning about a new technology pineapple in ghana this paper investigates the role of social learning in the diffusion of a new agri cultural technology in ghana we use unique data on farmers communication patterns to define each individual s information neighborhood conditional on many potentially confounding variables we find evidence that farmers adjust their inputs to align with those of their information neighbors who were surpris ingly successful in previous periods the relationship of these input adjustments to experience further indicates the presence of social learning in addition applying the same method to input choices for another crop of known technol ogy correctly indicates an absence of social learning effects jel d83 013 033 q16

development of financial markets and the size distribution of manufacturing establishments international comparisons abstract institutional determinants have largely been neglected in explaining international differences in the size distribution of manufacturing establishments this paper draws on recent developments in institutional analysis to derive certain hypotheses concerning the way in which the size distribution within manufacturing is affected by the degree of development of the markets for debt and equity these hypotheses are tested on the basis of an international cross section of 54 countries the results are generally supportive of the hypotheses especially in the case of developing countries

women as policy makers evidence from a randomized policy experiment in india this paper uses political reservations for women in india to study the impact of women s leadership on policy decisions since the mid 1990 s one third of village council head positions in india have been randomly reserved for a woman in these councils only women could be elected to the position of head village councils are responsible for the provision of many local public goods in rural areas using a dataset we collected on 265 village councils in west bengal and rajasthan we compare the type of public goods provided in reserved and unreserved village councils we show that the reservation of a council seat affects the types of public goods provided specifically leaders invest more in infrastructure that is directly relevant to the needs of their own genders

introduction imperfect information and rural credit markets puzzles and policy perspectives rural credit markets have been at the center of policy intervention in developing countries over the past forty years many governments supported by multilateral and bilateral aid agencies have devoted considerable resources to supplying cheap credit to farmers in a myriad of institutional settings the results of many of these interventions have been disappointing and one explanation for this must be that they were based on an inadequate understanding of the workings of rural credit markets the articles in this symposium issue are devoted to empirical and theoretical investigations of rural credit markets in the framework of the imperfect information paradigm the authors show how this framework is useful not only in explaining puzzling features of these markets but also in providing a policy perspective to assess the successes and failures of specific interventions

determinants of inter firm technology licensing in the eu this article investigates the determinants of technology licensing focusing on how country specific characteristics affect technology holders incentives to sell their proprietary technologies through licensing alliances an empirical examination of licensing is done using a unique panel data set of licensing transactions involving companies in the eu the strength of intellectual property rights ipr protection the degree of economic freedom the level of country risk and the number of patent granted in the country are found to be important determinants of inter firm technology licensing in addition firms with prior independent experience as a licensor and public companies tend to license technology more

domestic violence a nonrandom affair in this paper we develop and estimate a model of domestic violence we extend a noncooperative model of the family to include violence as a source of gratification and an instrument for controlling behavior we estimate the model by robust methods since the violence process appears to have a heavy tailed nonnormal error distribution we find that the properties of the equilibria depend on family income for low middle income families our results indicate an equilibrium in which one person s reservation utility constraint is binding whereas for higher income families both individuals may gain from the relationship

assessing the functioning of land rental markets in ethiopia although a large theoretical literature discusses the possible inefficiency of sharecropping contracts the empirical evidence on this phenomenon has been ambiguous at best household level fixed effect estimates from about 8 500 plots operated by households that own and sharecrop land in the ethiopian highlands provide support for the hypothesis of marshallian inefficiency at the same time a factor adjustment model suggests that the extent to which rental markets allow households to attain their desired operational holding size is extremely limited our analysis points towards factor market imperfections no rental for oxen lack of alternative employment opportunities and tenure insecurity as possible reasons underlying such behavior suggesting that rather than worrying almost exclusively about marshallian inefficiency it is equally warranted to give due attention to the policy framework within which land rental markets operate

subsistence response to market shocks microeconomic models posit that transaction costs isolate subsistence producers from output market shocks we integrate microeconomic models of many heterogeneous households into a general equilibrium model and show that supply on subsistence farms may respond in apparently perverse ways to changes in output market prices price shocks in markets for staple goods are transmitted to subsistence producers through interactions in factor markets in the case presented a decrease in the market price of maize reduces wages and land rents stimulating maize production by subsistence households however real incomes of subsistence households fall

social networks and technology adoption in northern mozambique despite their potentially strong impact on poverty agricultural innovations are often adopted slowly using a unique household dataset on sunflower adoption in mozambique we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks since farmers anticipate that they will share information with others we expect farmers to be more likely to adopt when they know many other adopters dynamic considerations however suggest that farmers who know many adopters might strategically delay adoption to free ride on the information gathered by others we present empirical evidence that shows that the relationship between the probability of adoption and the number of known adopters is shaped as an inverse u in line with information sharing the network effect is stronger for farmers who report discussing agriculture with others the data contains information which is needed to ameliorate the identification issues that commonly arise in this context in particular social networks are precisely identified and in addition we can control for village heterogeneity and endogenous group formation

technological capabilities and industrialization abstract this paper reviews the implications for industrial strategy of recent research on technological capabilities at the firm and national levels after exploring the nature and determinants of microlevel technological development a simple framework for explaining the growth of national capabilities is set out based on the interplay of incentives capabilities and institutions each may suffer market failure and so require corrective intervention the experience of some industrializing countries is described to assess the validity of this framework it is concluded that interventions carefully and selectively applied are necessary for industrial success

a structuralist perspective on the role of technology in economic growth and development abstract this paper presents an integrated view of what is termed a structuralist perspective to economic growth and development that stands in contrast to the mainstream orthodox or neoclassical view in the structuralist view structural changes are causes of growth rather than outcomes of a process of capital accumulation and of rising per capita incomes moreover the growth process may be punctuated by periods of discrete shifts in resource allocation creative destruction and growth acceleration rather than being smooth throughout structural changes need not be automatic they require a skill specific infrastructure of new capabilities which when established generate new comparative advantages market failures may be pervasive due to problems of human capital accumulation critical mass and discrete choice among alternative growth paths thus in addition to creating a favorable environment for business and assuring through macroeconomic policy adequate investment successful growth may require an adequate industrial and technological policy particularly at nodes of structural change the paper surveys the structuralist insights appearing in the literature starting with the early postwar economic development literature and including recently developed formal models it also proposes a kinked or scalloped aggregate production function as a simple tool for structuralist analysis

the government financial system and large private enterprises in the economic development of south korea abstract the paper investigates the main characteristics of the government business relationship in south korea in the past three decades to find out how it may have contributed to south korea s economic development it proposes that the government and large private enterprises in south korea should be viewed as constituting an internal organization namely a quasi internal organization as such extensive intervention by the government with south korea s financial system can be viewed as an internal capital market and consequently it could have led to a more efficient allocation of credit than possible in a free market financial system it also argues that the quasi internal organization has made it possible for the government to efficiently implement its developmental policies it is however pointed out that for the quasi internal organization to be successful in accelerating the pace of economic development the country must have a political leadership committed to the goal of economic development and must adopt an outward oriented development policy

earnings social security legislation and retirement decisions the austrian experience this paper analyses the labour supply behaviour of elderly males in austria and asks how far it is determined by the characteristics of the austrian social security system this is of particular interest because old age insurance in austria is dominated by the public pension plan so that private pension plans are of minor importance i argue that from a theoretical point of view the actuarial unfairness of the insurance plan creates a strong incentive to withdraw from the labour force at the minimum retirement age secondly the rising earnings replacement ratio might be responsible for the decreasing average retirement age these hypotheses are tested empirically a pooled time series cross sections labour force participation model is estimated for single birth year cohorts of elderly males i find strong evidence for the proposition that the age participation pattern might be determined by the incentives created by social security and that the decrease in labour force participation rates over time may

can social protection work in africa the impact of ethiopia s productive safety net programme abstractthis study evaluates a large social protection program in rural ethiopia the productive safety net programme psnp the effectiveness of the psnp is of interest because the program was implemented at scale in one of africa s poorest countries which has limited physical and communications infrastructure and scarce administrative resources using longitudinal survey data collected in 2006 2008 and 2010 at the household and locality levels we employ an extension of the propensity score matching method to continuous treatments to estimate the impact of transfers from the psnp and a separate program on household food security against the formidable background of rising food prices and widespread drought participation in the public works component of the psnp has modest effects the psnp reduced the length of the last hungry season by 1 29 months among households that received transfers for 5 years compared to eligible households that received almost nothing five years of participation raises l

risk sharing networks and insurance against illness most risk sharing tests on developing country data are conducted at the level of the village generally the full risk sharing hypothesis is rejected this paper uses detailed data on all insurance networks within a village in tanzania networks are not clustered but largely overlapping we test whether full risk sharing occurs within these networks while village level full insurance cannot be rejected for food consumption we find evidence consistent with at least partial insurance of non food consumption via networks

credit markets in northern nigeria credit as insurance in a rural economy this article addresses the issues of imcomplete markets and imperfect information in the context of credit markets in rural northern nigeria in much recent theoretical literature the problems of moral hazard and adverse selection are assumed to be decisive for the organization of agrarian institutions in contrast it is found that in the four villages surveyed credit transactions take advantage of the free flow of information within rural communities information asymmetries between borrower and lender are unimportant and their institutional consequences the use of collateral and interlinked contracts are absent credit transactions play a direct role in pooling risk between households through the use of contracts in which the repayment owed by the borrower depends on the realization of random production shocks by both the borrower and the lender

the gender wage gap and domestic violence three quarters of all violence against women is perpetrated by domestic partners this study exploits exogenous changes in the demand for labor in female dominated industries to estimate the impact of the male female wage gap on domestic violence decreases in the wage gap reduce violence against women consistent with a household bargaining model these findings shed new light on the health production process as well as observed income gradients in health and suggest that in addition to addressing concerns of equity and efficiency pay parity can also improve the health of american women via reductions in violence

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

tenure insecurity gender low cost land certification and land rental market participation in ethiopia abstract there is a renewed interest in whether land reforms can contribute to market development and poverty reduction in africa this paper assesses effects on the allocative efficiency of the land rental market of the low cost approach to land registration and certification of restricted property rights that was implemented in ethiopia in the late 1990s four rounds of a balanced household panel from 16 villages in northern ethiopia are analysed showing that land certification initially enhanced land rental market participation of potential tenant and landlord households especially those that are headed by females

banking reform and the financing of firm investment an empirical analysis of the chilean experience 1983 92 this article investigates whether the chilean banking reforms of the 1980s have contributed to reducing market imperfections in chilean financial markets in the late 1980 and early 1990s to analyse this issue patterns of investment and its finance for different types of firms are studied based on balance sheet information of a panel of 70 firms the most important conclusion is that those specific reforms aimed at reducing intra conglomerate lending seem to have been successful since access of non conglomerate firms has increased indicating a reduction of existing market imperfections for such firms

a revised tobit procedure for mitigating bias in the presence of non zero censoring with an application to milk market participation in the ethiopian highlands fixed transactions costs that prohibit exchange engender bias in supply analysis due to censoring of the sample observations the associated bias in conventional regression procedures applied to censored data and the construction of robust methods for mitigating bias have been preoccupations of applied economists since tobin econometrica 26 1958 24 this literature assumes that the true point of censoring in the data is zero and when this is not the case imparts a bias to parameter estimates of the censored regression model we conjecture that this bias can be significant affirm this from experiments and suggest techniques for mitigating this bias using bayesian procedures the bias mitigating procedures are based on modifications of the key step that facilitates bayesian estimation of the censored regression model are easy to implement work well in both small and large samples and lead to significantly improved inference in the censored regression model these findings are important in light of the widespread use of the zero censored tobit regression and we investigate their consequences using data on milk market participation in the ethiopian highlands

inequality and crime this paper considers the relationship between inequality and crime using data from urban counties the behavior of property and violent crime are quite different inequality has no effect on property crime but a strong and robust impact on violent crime with an elasticity above 0 5 by contrast poverty and police activity have significant effects on property crime but little on violent crime property crime is well explained by the economic theory of crime while violent crime is better explained by strain and social disorganization theories

learning by doing and learning from others human capital and technical change in agriculture household level panel data from a nationally representative sample of rural indian households describing the adoption and profitability of high yielding seed varieties hyvs associated with the green revolution are used to test the implications of a model incorporating learning by doing and learning spillovers the estimates indicate that i imperfect knowledge about the management of the new seeds was a significant barrier to adoption ii this barrier diminished as farmer experience with the new technologies increased iii own experience and neighbors experience with hyvs significantly increased hyv profitability and iv farmers do not fully incorporate the village returns to learning in making adoption decisions

a dynamic stochastic frontier model to evaluate regional financial efficiency evidence from chinese county level panel data abstract studies have widely used stochastic frontier models to assess financial efficiency however traditional static approaches do not take dynamic characteristics of financial systems into account this article develops a dynamic stochastic frontier model to evaluate regional financial efficiency and provides an empirical test of the model by using panel data of 62 chinese counties during the 2001 2010 period the model measures the dynamic impact of the input output variables and environmental variables on financial efficiency and allows for the separation of technical change from the change in technical efficiency the results show that the dynamic model provides a better fit to the data than the static model in addition a gradient difference emerges in the regional financial efficiency among the six major regions of china the results offer practical implications for the development of regional financial services in china as well as other developing countries and emerging economies

social networks and factor markets panel data evidence from ethiopia we investigate the role of an indigenous social network in ethiopia the iddir in facilitating factor market transactions among smallholder farmers we use detailed longitudinal household survey data and employ fixed effects estimation approaches to identify the effect of iddir membership on factor market transactions among farmers we find that joining an iddir network improves households access to land labour and credit transactions our findings also hint that iddir networks may crowd out borrowing from local moneylenders locally referred as arata abedari a relatively expensive credit source these results suggest that non market institutions can play crucial roles in facilitating market transactions

social networks and credit access in indonesia abstract in this paper we investigate how family and community networks affect an individual s access to credit institutions using new data from the indonesia family life surveys our theoretical framework emphasizes the family and community s role in providing information thus lowering the search costs of the borrower and monitoring and enforcement costs for the lender from our empirical results community and family networks are important in knowing a place to borrow as well as for loan approval consistent with an information based explanation of networks family and community networks have a larger impact on credit awareness of new credit institutions with a lower impact on awareness of established credit sources interestingly we find that women benefit from participating in community networks more than men there is no evidence that the rich benefit from community networks more than the poor our results on the benefits from participation in the community network are robust to the inclusion of community fixed effects

financial systems in northern thai villages field research attempted to measure the risky environments the information structures the institutions and the risk response mechanisms of ten villages in northern thailand various key features are then modeled in an abstract but realistic way either with a full information risk sharing model or an information constrained version of the same model observations from some of the villages seem consistent with one or the other of these models but in many of the villages one is left with risk response variations across households which suggest that pareto improvements are possible

fortune favors the prepared firm a critical factor in industrial competitiveness is the ability of firms to exploit new technological developments we term this ability a firm s absorptive capacity and argue that such a capability not only enables a firm to exploit new extramural knowledge but to predict more accurately the nature of future technological advances we develop a stylized model in which we focus exclusively on firms decisions to invest in their absorptive capacities we first examine a monopolist s investment decision analyzing the path dependence of its investment and the effect of uncertainty we then consider the effect of competition by modeling the impact of entry on an incumbent s investment behavior implications for management and public policy are then discussed

kinship and financial networks formal financial access and risk reduction kinship networks are beneficial for smoothing consumption and investment but the channels are not well understood we study the financing devices used for consumption and investment by thai households households that are connected to banks achieve significantly better consumption smoothing than unconnected households indirect connections via inter household borrowing are as effective as direct borrowing investment appears to be facilitated by kinship households with kin in the village display reduced sensitivity of investment to income while connections to banks do not significantly reduce sensitivity kin may act as implicit collateral permitting borrowing that would violate repayment constraints in its absence

social connections and group banking lending to the poor is expensive due to high screening monitoring and enforcement costs group lending advocates believe lenders overcome this by harnessing social connections using data from finca peru i exploit a quasi random group formation process to find evidence of peers successfully monitoring and enforcing joint liability loans individuals with stronger social connections to their fellow group members i e either living closer or being of a similar culture have higher repayment and higher savings furthermore i observe direct evidence that relationships deteriorate after default and that through successful monitoring individuals know who to punish and who not to punish after default

south korean and taiwanese development and the new institutional economics the publication of books by both alice amsden and robert wade provide an opportune moment to reflect on the study of east asian development after an initial surge of interest beginning in the 1970s the field has reached a plateau and scholars recently have cast a wide net in searching for ways to extend the field in assessing the state of the art regarding the economic development of the east asian newly industrialized countries nics this review will treat three themes first i will argue that the focus on states versus markets is becoming stale and that much of the scholarly interest lies in the politics behind the economics second i argue that political scientists have underexplored the historical origins of korean and taiwanese capitalism and that such attention promises to strengthen both theories and explanations of development third i argue that the international system has been more important in promoting development in east asia than accounts in the first wave have recognized the purpose of this review is to assess the field reveal

credit constraints and agricultural productivity evidence from rural rwanda while potentially negative impacts of credit constraints on economic development have long been discussed conceptually empirical evidence for africa remains limited we use a direct elicitation approach on a national sample of rwandan rural households to empirically assess the extent and nature of credit rationing in the semi formal sector and its impact using an endogenous switching model elimination of all constraints could increase output by some 17 per cent implications for policy and research are spelled out

the impact of ethiopia s productive safety net programme and its linkages abstract this paper assesses the impact of ethiopia s productive safety nets programme psnp the largest social protection programme in sub saharan africa outside of south africa using propensity score matching techniques we find that the programme has little impact on participants on average due in part to transfer levels that fell far below programme targets participants with access to both the psnp and packages of agricultural support are more likely to be food secure to borrow for productive purposes use improved agricultural technologies and operate non farm own business activities however beneficiaries did not experience faster asset growth

peasant household behaviour with missing markets some paradoxes explained a model of peasant household behavior under varying degrees of household specific food and labor market failures is constructed to show that these structural features can explain several well known patterns of peasant response which have often been attributed to peculiar motives presumed specific to peasants the model explains sluggish response to cash crops prices and high instability in perceived food and labor scarcities the key role of manufactured consumer goods prices in stimulating peasants effort in cash crops production the effectiveness of taxation as opposed to incentives in stimulating cash crops production and the key role of technological change in food production to enhance cash crop production results are obtained analytically in the case of one market failure and by numerical simulation with more than one

development and social capital abstract this paper examines social capital and its relation with economic development we focus on the role that interpersonal relationships play in social exchange whether through the market or through the provision of public goods by facilitating search and trust social capital can increase the efficiency of social exchange where formal institutions are weak but the benefits from social capital are likely to be unequally distributed given these features documenting empirically the benefits of social capital is complicated by the presence of negative and positive externalities and by the existence of leadership and group effects lessons for development policy are drawn at the end

exports economic growth and the consolidation of peace in el salvador abstract the pillars of inclusive growth in el salvador have to be nontraditional export growth investment and government determination to reduce income inequality and poverty this article analyzes the key obstacles to the development of a competitive and dynamic export sector dutch disease driven by aid and remittances a significant decline in real wages and lack of productivity growth policies can and must focus on productivity growth rather than wage repression in the pursuit of peace consolidation and long term competitiveness

shifts over time and regional variation in women s labor force participation rates in a developing economy abstract in this study an attempt is made a to explain the decline and the inter area variation in women s activity rates in greece during the process of its economic development b to ascertain if there were any shifts in the relevant relationships over time and c to estimate women s hidden unemployment the decline in activity rates was explained with the help of the hypothesis of a u shaped impact of economic development on them among the most important findings were the considerable discouraging effect on labor force participation of unemployment and the negative impact of education women s hidden unemployment was found to be two to three times larger than reported unemployment

scale economies wage differentials and north south trade abstract this paper attempts to isolate the effect of external economies of scale in production on the pattern of north south trade the results show that when the relative wage is higher in the north and only the north innovates the south produces and exports those goods with the lowest economies of scale while the remaining set of goods is produced and exported by the north production subsidies offered by the south raise southern income and welfare but if the north introduces a new set of goods the benefits of the subsidies to the south dissolve

group based funeral insurance in ethiopia and tanzania a funeral is a costly occasion this paper studies indigenous insurance institutions developed to cope with the high costs of funerals based on evidence from rural areas in tanzania and ethiopia these institutions are based on well defined rules and regulations often offering premium based insurance for funeral expenses increasingly they are also offering other forms of insurance and credit to cope with hardship the paper argues that the characteristics and inclusiveness of these institutions make them well placed as models to broaden insurance provision and other developmental activities in these communities the history of these institutions is characterised by a resistance to attempts of political capture and helps to understand their apparent resistance to engage more broadly with ngos and government agencies as a result any attempt to expand their activities will have to be done cautiously

externalities in economies with imperfect information and incomplete markets this paper presents a simple general framework for analyzing externalities in economies with incomplete markets and imperfect infonnation by identifying the pecuniary effects of these externalities that net out the paper simplifies the problem of determining when tax interventions are pareto improving the approach indicates that such tax interventions almost always exist and that equilibria in situations of imperfect information are rarely constrained pareto optima it can also lead to simple tests based on readily observable indicators of the efficacy of particular tax policies in situations involving adverse selection signaling moral hazard incomplete contingent claims markets and queue rationing equilibria traditional discussions of externalities have emphasized the distinction between technological externalities in which the action of one individual or firm directly affects the utility or profit ofanother and pecuniary externalities in which one individual s or firm s actions affect another only through effects on prices while the presence of technological externalities imply in general that a competitive equilibrium may not be pareto efficient pecuniary externalities hy themselves are not a source of inefficiency the fact that prices change has of course important consequences there are both distributional and allocational effects but the distribution effects net out gains for example hy firms whose prices increase are precisely offset by losses e g to individuals who must pay higher prices and there are no welfare losses from the allocation effects as long as the price changes involved are small if firms are maximizing profits and individuals are maximizing utility both facing prices that correctly refiect opportunity costs then standard envelope theorem arguments imply that changes in profits or utility induced by changes in allocations resulting from any small change in prices are negligible

when are sanctions effective a bargaining and enforcement framework although a considerable literature identifies the conditions under which sanctions are more likely to be successful few studies examine the question of when sanctioning states or senders are willing to enforce their sanctions laws against their firms using a game theoretic model we argue that imposing sanctions creates a strategic dilemma for senders we demonstrate that senders often have disincentives to enforce their sanctions policies given that the restriction on economic transactions with targeted states may undermine their firms competitiveness the model indicates that sanctions are more likely to succeed when the sender s firm retains a moderate share of the target s market relative to its foreign competitors however the model also demonstrates that sanctions are likely to be imposed only when the conditions do not favor their success the empirical implications of the model are tested using the threat and imposition of economic sanctions ties data set

risk attitudes and economic well being in latin america abstract a common conjecture in both the theoretical and policy literatures on development is that people remain poor because they are too impatient and risk averse to accumulate the resources needed to improve their well being the empirical literature however suggests that this conjecture is far from proven we sample more than 3000 participants drawn representatively from six latin american cities and find little correlation between baseline risk aversion and well being measured as an index of eight outcomes we do however find that measures of ambiguity aversion loss aversion and the willingness to take advantage of a risk pooling scheme all correlate with well being participants who are ambiguity averse loss averse and who react conservatively in the risk pooling condition all have significantly lower scores on our well being index these results are robust to the inclusion of a variety of important controls like human capital accumulation and access to credit

markets market failures and development a central question in development economics is how can we account for differences in the levels of income and the rates of growth between the developed and less developed economies in the 1950s and 1960s there was a standard answer to this question the poor are just like the rich except they are poorer they have less human and nonhuman capital there was an immediate prescription for this diagnosis increase the resources of ldcs either by transferring capital to them either direct aid or education or by encouraging them to save more today these answers seem less convincing that they did two decades ago if the problem were primarily a shortage of physical capital the return to capital should be much higher in ldcs than in developed countries and the natural avarice of capitalists would lead to a flow of capital from the more developed to the less developed economies see howard pack 1984 and my 1988 paper if the problem were primarily a shortage of human capital then the educated in ldcs should receive a higher absolute as well as relative income than the educated in more developed economies how then can we account for high levels of unemployment among the educated and the migration of the educated from ldcs to more developed economies moreover the predictions of the standard neoclassical growth model of a convergence of growth rates in per capita income with permanent differences in per capita consumption being explained by differences in savings rates and reproduction rates do not seem to have been borne out these observations suggest that the ldcs differ from the developed countries in at least some other important respects and this view is corroborated by those studies which have looked at the productivity of similar plants operating in developed and less developed economies see pack 1984 1987 the difference can be attributed perhaps tautologically to differences in economic organization to how individuals factors of production interact and to the institutions which mediate those interactions among the most important of these institutions are markets it is by now well recognized that there are many instances of market failures in more developed economies see bruce greenwald and myself 1986 in some cases market failures may be ameliorated by nonmarket institutions if for instance capital markets do not function well perfectly if only because of costly and imperfect information nonmarket institutions internal capital markets within large conglomerates may develop market failure is more prevalent in ldcs and the nonmarket institutions that ameliorate its consequences are at least in many instances less successful in doing so the objective of this paper is to explore the causes and consequences of these market failures and the failure of private nonmarket solutions and to suggest possible roles for government intervention tdiscussants anne 0 krueger duke university stanley fischer world bank

imperfect information screening and the costs of informal lending a study of a rural credit market in pakistan many governments have perceived the rural moneylender as usurious this article takes a first step toward directly testing the validity of this view in a study of services costs and charges of fourteen informal market moneylenders and their clients in chambar pakistan the article examines whether the high implicit interest rates charged reflect the actual costs of operating in that market estimates of the resource costs incurred by informal lenders for screening pursuing delinquent loans overhead and cost of capital including unrecoverable loans suggest that lenders charges are equal to their average cost of lending but exceed their marginal cost this finding is consistent with the view that the informal credit market is characterized by excess capacity and monopolistic competition in the presence of imperfect information

a trivariate model of participation fertility and wages the italian case italy has unusually low fertility by organization of economic cooperation and development standards accompanied by unusually low female participation in paid work this paper addresses the issue of the empirical relationship between fertility female participation in the labor market and wages with these italian peculiarities as a backcloth a trivariate model of participation fertility and wages has been constructed and estimated using three pooled cross sections of italian micro data allowing for the identification of cohort effects this model follows a purist approach the participation and fertility decisions as well as the wage equation are modeled as completely joint the cohort effects turn out to be significant the point estimates do not appear to confirm actual trends which are negative for fertility and positive for participation the female wage is the most important variable influencing the propensity to have children and the propensity to participate in the labor market casting doubt on suggestions that observed trends are the products of shifts in womens tastes authors

direct elicitation of credit constraints conceptual and practical issues with an application to peruvian agriculture abstract this article provides a methodological bridge leading from the well developed theory of credit rationing to the less developed territory of empirically identifying credit constraints we begin by developing a simple model showing that credit constraints may take three forms quantity rationing transaction cost rationing and risk rationing each form adversely affects household resource allocation and thus should be accounted for in empirical analyses of credit market performance we outline a survey strategy to directly elicit households status as unconstrained or constrained in the credit market and if constrained to further identify which of the three nonprice rationing mechanisms is at play we discuss several practical issues that arise due to the use of a combination of factual and interpretative survey questions finally using a farm level data set from peru we illustrate how the methodology can be used to estimate the impacts of credit constraints

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

evidence from mexico on social status and violence against women this study investigates the impact of relative social status on violence against women in mexico using state level panel data relatively higher female social status measured by educational economic and political standings is associated with lower homicide rates for women and lower intimate partner violence rates more importantly different status variables affect violence against women through different channels depending on the victim offender relationship the results are robust to different specifications and different control variables this study may provide helpful guidelines to policy makers attempting to identify more effective means for deterring violence against women

income portfolios in rural ethiopia and tanzania choices and constraints the article analyses the different income portfolios of households using survey data from rural ethiopia and rural tanzania it suggests that the different portfolios held by households cannot be e

social networks neighborhood effects and credit access evidence from rural guatemala we measure the extent to which social networks determine sources of credit from a survey of 465 households in western guatemala we estimate correlated contextual and endogenous effects of networks at the neighborhood church and village levels finding that church networks display endogenous effects in credit access we calculate an elasticity of social imitation esi indicating if the percentage of people accessing microfinance in a church network doubles the probability of an individual household accessing microfinance increases by 14 1 percent a magnitude similar to our estimated esis for televisions and cell phones within church and neighbor networks

risk matching behavior in microcredit group formation evidence from northern ethiopia theoretical models on group lending assume the formation of groups of homogenous risk types recent theoretical and empirical findings challenge this view arguing that when markets for insurance are missing risk homogeneity may not hold any more and risk heterogeneity can be the optimal outcome using data from an mfi in tigray ethiopia this article examines the homogeneity hypothesis and reflects on implications for repayment no evidence is found that supports risk homogeneity even accounting for matching frictions however we also do not find an explicit link between the presence of risk heterogeneity and side payments due to missing insurance as suggested in the literature instead other trust based social networks seem to underlie heterogeneity such social networks are often synchronized with credit groups and influence the probability of repayment under heterogeneity the implication is that successful repayment rates in group lending need not arise only under risk homogeneity but can also arise under risk heterogeneity heterogeneity may also serve to bridge missing insurance markets in poor rural environments mfis therefore need to consider such local conditions when designing their lending schemes

characterizing social networks and their effects on income diversification in rural kerala india summary income diversification continues to be a key strategy for poor rural households including those that are progressively developing and those operating under increasing distress the ability of a household to diversify has been shown to depend upon its demographic and economic characteristics and its physical and social context this paper considers the effects of intra village social networks on household income diversification in one of the poorest and most ethnically diverse areas of the indian state of kerala using techniques adapted from spatial econometrics we find that social connections within a village magnify the impacts of household characteristics such as education and number of adults by a factor of 3 6 times models with alternative measures of network centrality degree and eigenvector indicate that the number of network connections that a household has is more important than the centrality of those connections finally we use social contact information to calculate assortative mixing based on caste the results suggest social stratification in these villages with higher levels of stratification associated with lower levels of income diversification

economics imperialism and the new development economics as kuhnian paradigm shift abstract this paper addresses the evolving relationship between economics and other social sciences it sets the present intellectual scene as one in which economics imperialism is rampaging across other disciplines the designs of economics upon development studies are examined in terms of the kuhnian notion of paradigm shift thereby the conclusion is drawn of the potential prospect of open debate around the economy and development not least outside economics itself but there is danger of economics imperialism in the form of the post washington consensus foreclosing the analytical agenda at the expense of approaches based on the political economy of capitalism

women as agents of change female income and mobility in india economic globalization will give many women in developing countries access to steady and relatively remunerative employment for the first time potentially shifting bargaining power within their households and changing the choices that are made for their children this paper exploits a unique setting a group of tea plantations in south india where women are employed in permanent wage labor and where incomes do not vary by caste to anticipate the impact of globalization on mobility across social groups in the future the main result of the paper is that a relative increase in female income weakens the family s ties to the ancestral community and the traditional economy but these mobility enhancing effects are obtained for certain historically disadvantaged castes alone although the paper provides a context specific explanation for why the women from these castes emerge as agents of change the first general implication of the analysis is that the incentive and the ability of women to use their earnings to influence household decisions depends importantly on their social background the second implication is that historically disadvantaged groups may in fact be especially responsive to new opportunities precisely because they have fewer ties to the traditional economy to hold them back

political connections and social networks in targeted transfer programs evidence from rural ethiopia abstractdespite increasingly large scale social protection programs in africa we have limited evidence on the local political economy of their allocation we investigate community based processes for food aid allocation and the role of political and social networks using the case of ethiopia in the aftermath of a serious drought in 2002 local political authorities are in charge of food transfers in terms of free food aid or food for work programs we find that although targeting is clearly imperfect free food aid is responsive to need as well as targeted to households with less access to support from relatives or friends we also find a strong correlation with political connections households with close associates in official positions have more than a 12 higher probability of obtaining free food than households that are not well connected this effect is large someone without political connections has the same probability of getting food aid as someone more than twice as rich but with these conne

income risk the tax benefit system and the demand for children because children represent an irreversible commitment parents might hedge against higher income risk by having fewer children we show that under plausible assumptions recent increases in income risk might have reduced prudent parents desired fertility responses to this via the tax benefit system are considered introducing an expected revenue neutral transfer cum child benefit system under proportional taxation which lets the government share the household s income risk increases desired fertility for parents who would choose to have small families in this system s absence pound for pound the targeted child benefit enhances fertility more than the lump sum transfer

fertility and the tax benefit system a reconsideration of the theory of family taxation the author examines the simultaneous nature of the decision to have children the decision to spend money on them and the decision to seek employment it will be argued that the children income trade off emphasised by the present paper is more relevant to most family decisions than the income leisure trade off on which much of the policy debate has been centred in order to do that we shall bring together the recently developed economic theory of the family or new home economics with the microeconomic branch of the theory of public finance a model of family choice is developed the main message of the present paper is that if as the evidence suggests parents have some control over the number of children they put into the world then the effect of taxes and subsidies on the familys allocation of time and money will be generally weaker and in some respects the opposite of what it would be if the number of children were physiologically constrained or exogenously given another is that if parents derive utility from having children this has to be taken into account in any welfare calculation fertility may thus affect the design of optimal policy in two ways indirectly through its effect on market behaviour and directly through its effect on welfare excerpt

a model of female labor supply in italy using cohort data this paper attempts to develop a behavioral model of female labor supply in italy using cohort data our starting theoretical assumptions of perfect information intertemporal separability and utility maximization under a lifetime wealth constraint are relaxed in a second stage the results suggest that the flat female participation rate profile from both a time series and a cross section perspective is presumably produced by economic incentive effects that counter balance each other however with the recent rise in cohort specific earning power we identify a decrease in the work disincentive effects of aging and of children under 6

the meaning of kinship in sharecropping contracts analysis of a household survey from the philippines shows that the behavior of sharecroppers with a kinship relation with their landlord is not affected by the disincentive effects of product and factor sharing while behavior of the other sharecroppers responds to the contract terms we characterize the meaning of kinship ties through a survey of opinion conducted among tenants the survey shows that kin landlords help or are expected to help more frequently in case of emergency than other landlords and they do so with a wider range of instruments providing the incentive for cooperative behavior in sharecropping contracts among kin

privatization and economic growth an empirical investigation from a sample of developing market economies this paper explores the economic determinants of privatization programmes and the macroeconomic impact of this institutional reform on the growth rate of the gdp a sample of thirty five developing market economies is considered over the 1988 92 period probit and tobit models are used to identify the determinants of successful privatization programmes then regressions are run where probabilities probit and expected values tobit are successively included as additional regressors beside the potential influence of other economic policy variables a significant positive effect is highlighted giving evidence of the importance of divestiture the economic effect is found to be stronger when this institutional reform took place in industry or infrastructure

interactions between institutional and informal credit agencies in rural india in an attempt to expand rural credit and displace the village moneylender india created a system of rural cooperatives in the 1950s and expanded branch banking into rural areas in the 1970s this article examines how these measures affected the rural market it begins with the question of how large the expansion of institutional credit has been and the extent to which it has dislodged the village and nonresident moneylenders a detailed comparison of three major surveys of the indian rural credit market suggests that in various guises the moneylender is still a major source of loans the article also examines the weak evidence on intermediation between the formal and informal sectors a formal model of the interaction between the informal moneylender and institutional lender is constructed under a variety of assumptions about the exclusivity of loan contracts and the competitive structure of the informal sector the conclusions are drawn together in the form of five proposals for public policy

consumption risk technology adoption and poverty traps evidence from ethiopia much has been written on the determinants of input and technology adoption in agriculture with issues such as input availability knowledge and education risk preferences profitability and credit constraints receiving much attention this paper focuses on a factor that has been less well documented the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests building on an explicit model this is explored in panel data for ethiopia historical rainfall distributions are used to identify the counterfactual consumption risk controlling for unobserved household and time varying village characteristics it emerges that not just ex ante credit constraints but also the possibly low consumption outcomes when harvests fail discourage the application of fertilizer the lack of insurance causes inefficiency in production choices
