entrepreneurship versus joblessness explaining the rise in self employment a large share of the workforce throughout the developing world is self employed and this proportion has increased in recent decades assessments of this development vary with pull factors such as high returns to capital contrasted with push factors such as barriers to more desirable salaried jobs using a long panel dataset from ghana we empirically investigate the changing structure of earnings in self employment relative to salaried work our analysis allows workers to sort into self employment for different reasons including expected earnings differentials and endogenous capital accumulation whilst highlighting constraints that workers may face we estimate a correlated random coefficient model using iv gmm taking into account the endogeneity of sector choice and capital accumulation we find that returns to productive characteristics in self employment have increased significantly between 2004 and 2011 whilst self employment has attracted increasingly skilled workers this points against the negative view of self employment as an occupation of last resort

an economic theory of self control the concept of self control is incorporated in a theory of individual intertemporal choice by modeling the individual as an organization the individual at a point in time is assumed to be both a farsighted planner and a myopic doer the resulting conflict is seen to be fundamentally similar to the agency conflict between the owners and managers of a firm both individuals and firms use the same techniques to mitigate the problems which the conflicts create this paper stresses the implications of this agency model and discusses as applications the effect of pensions on saving saving and the timing of income flows and individual discount rates

does microfinance change informal lending in village economies evidence from bangladesh this paper examines how availability of microfinance influences households borrowing from informal sources in village economies it uses a unique household level panel data set which spans more than two decades 1987 2008 from rural bangladesh we find that households access to microfinance reduces the incidence of borrowing from informal sources but not the amount of borrowing we find that less poor households benefit more in terms of reducing their reliance on informal borrowing and that the benefit accrues over time we also find that having access to microfinance increases women s informal borrowing for small consumption usage without facilitating access to new business opportunities

revealed objective functions of microfinance institutions evidence from bangladesh abstract this paper discerns between two alternative objective functions for not for profit microfinance institutions mfis profit maximization and poverty targeting i use the strategic branch location choices of the two largest mfis in a mature concentrated market to reveal their objectives i consider location decisions to be the pure strategy nash equilibrium outcome of a one shot game where the mfis simultaneously choose markets in which to locate as well as how many branches to open in each applying the duality principle i nest fully a pure profit maximization objective within a poverty targeting motive i test the model using comprehensive data from bangladesh in 2003 structurally estimating profit and impact functions my msm estimates suggest that pure profit maximization cannot explain the branch placement pattern for grameen bank or brac they both deviate towards poverty alleviation targeting one higher standard deviation of poverty headcount costs grameen 35 2 of its potential profits and brac 51 4

inefficient credit booms this paper studies the welfare properties of competitive equilibria in an economy with financial frictions hit by aggregate shocks in particular it shows that competitive financial contracts can result in excessive borrowing ex ante and excessive volatility ex post even though from a first best perspective the equilibrium always displays under borrowing from a second best point of view excessive borrowing can arise the inefficiency is due to the combination of limited commitment in financial contracts and the fact that asset prices are determined in a spot market this generates a pecuniary externality that is not internalized in private contracts the model provides a framework to evaluate preventive policies which can be used during a credit boom to reduce the expected costs of a financial crisis copyright 2008 wiley blackwell

from ngos to banks does institutional transformation alter the business model of microfinance institutions microfinance which pledges to provide financial services to people without access to banking is chiefly run by non governmental organizations ngos little is known about the extent to which the transformation of these ngos into shareholder owned and most often regulated firms affects the way microfinance institutions mfis conduct their business by applying the event study methodology to 66 mfis that have transformed we quantify the effect that transformation has on the mfis business models our results suggest that portfolio yield is driven down by 3 9 percentage points due to transformation indicating that clients get more favorable interest rates at the same time mfis are able to significantly cut down their operational expenses of which 1 1 percentage points can be attributed to transformation other findings include a steep increase in commercial debt leverage and deposits a significant decrease in the fluctuation of funding costs and a sharp rise in average loan size profitability goes down in the short and medium term while return on equity is driven up in the medium to long run by exploiting within mfi data our approach goes beyond previous studies that mainly relied on between mfi data overall the results suggest that transformed mfis become an attractive environment for investors potentially encouraging a more profit seeking behavior among transformed mfis

where does microfinance flourish microfinance institution performance in macroeconomic context abstract we study whether and how the success of microfinance institutions mfi s depends on the country level context in particular macroeconomic and macro institutional features understanding these linkages can make mfi evaluation more accurate and further can help to locate microfinance in the broader picture of economic development we collect data on 373 mfis and merge it with country level economic and institutional data evidence arises for complementarity between mfi performance and the broader economy for example mfis are more likely to cover costs when growth is stronger and mfis in financially deeper economies have lower default and operating costs and charge lower interest rates there is also evidence suggestive of substitutability or rivalry for example more manufacturing and higher workforce participation are associated with slower growth in mfi outreach overall the country context appears to be an important determinant of mfi performance mfi performance should be handicapped for the environment in which it was achieved

an empirical investigation of rationing constraints in rural credit markets in india abstract the literature on rural credit markets has generally assumed that households are rationed in their access to subsidized formal credit the validity of this assumption depends on the level of effective demand for formal credit in turn a function of the demand for credit and its availability from informal sources this paper estimates the demand and the sector specific costs of credit and hence the extent of formal sector rationing through an analysis of household participation in both the formal and the informal credit sectors the results show that the extent of rationing is considerably less than what is conventionally assumed

scale economies and input price elasticities in microfinance institutions abstract we evaluate the efficiency of microfinance institutions mfis using a structural approach which also captures these institutions outreach and sustainability objectives we estimate economies of scale and input price elasticities for lending only and deposit mobilizing mfis using a large sample of high quality panel data the results confirm conjectures that improvements in efficiency can come from the growth or consolidations of mfis as we find substantial increasing returns to scale for all but profitability focused deposit mobilizing mfis our results support the existence of a trade off between outreach and sustainability all inputs are inelastic substitutes but we find differences in own price elasticities in lending only and deposit mobilizing mfis

gains from trade in a social choice context we ask whether there exists a rule in which nobody loses under trade liberalization we consider a resource allocation problem in which the traded commodities vary we propose an axiom stating that enlarging the set of tradable commodities hurts nobody we show that if a rule satisfies this axiom together with an allocative efficiency axiom and an institutional constraint axiom stating that only preferences over tradable commodities matter gains from trade can be given to only one individual in the first step of liberalization

mainstreaming microfinance social performance management or mission drift summary what scope is there for the pursuit of explicit development goals in the context of increasing integration of specialized microfinance and commercial banking sectors this question and the idea of mission drift is first analyzed using a model that distinguishes between institutions financial and social performance possibilities preferences and assessment systems the model is used to review findings from action research with an international sample of poverty oriented microfinance institutions that suggest some simple steps for improved social performance management it is then used to illustrate the relationship between social and financial performance more widely across the retail financial services sector and to offer pointers for more policy analysis at this level

a fairness justification of utilitarianism differences in preferences are important to explain variation in individuals behavior there is however no consensus on how to take these differences into account when evaluating policies while prominent in the economic literature the standard utilitarian criterion is controversial according to some interpersonal comparability of utilities involves value judgments with little objective basis others argue that social justice is primarily about the distribution of commodities assigned to individuals rather than their subjective satisfaction or happiness in this paper we propose and axiomatically characterize a criterion named opportunity equivalent utilitarian that addresses these claims first our criterion ranks social alternatives on the basis of individuals ordinal preferences second it compares individuals based on the fairness of their assignments opportunity equivalent utilitarianism requires society to maximize the sum of specific indices of well being that are cardinal interpersonally comparable and represent each individual s preferences

a biological basis for expected and non expected utility abstract a biological model is developed here to determine the fittest attitude to risk with a fixed environment the type maximizing expected offspring is selected this yields the expected utility theorem when translated into a criterion for evaluating gambles over commodities with a random environment however the type selected is strictly less averse to idiosyncratic risk than to risk which is correlated across all individuals the implied criterion for choice over gambles does not satisfy the expected utility theorem and may induce choice of a gamble which is first order stochastically dominated journal of economic literature classification number d81

cross country variation in household access to financial services abstract this paper presents estimates for more than 160 countries of the fraction of the adult population using formal financial intermediaries the estimates are constructed by combining information on account numbers at banks and microfinance institutions together with banking depth and gdp data with estimates from household surveys for a smaller set of countries an illustrative application of the data compares them with information on poverty there is a correlation but it is not clearly causal

generalized utilitarianism and harsanyi s impartial observer theorem harsanyi s impartial observer must consider two types of lotteries imaginary identity lotteries accidents of birth that she faces as herself and the real outcome lotteries life chances to be faced by the individuals she imagines becoming if we maintain a distinction between identity and outcome lotteries then harsanyi like axioms yield generalized utilitarianism and allow us to accommodate concerns about different individuals risk attitudes and concerns about fairness requiring an impartial observer to be indifferent as to which individual should face similar risks restricts her social welfare function but still allows her to accommodate fairness requiring an impartial observer to be indifferent between identity and outcome lotteries however forces her to ignore both fairness and different risk attitudes and yields a new axiomatization of harsanyi s utilitarianism

entrepreneurship social mobility and income redistribution in south india development economists have been preoccupied with the problem of increasing the size of the gnp pie to the relative neglect of its distribution despite the recent disenchantment with the viewpoint that all classes share in the benefits of industrial growth empirical data on the distribution of income business opportunity and economic power are in short supply many of the studies on entrepreneurship and economic development when they are not apologetics for ruthless capitalist exploitation as paul baran suggests extol the achievements of the capitalist entrepreneur without examining class origins and monopoly advantage joseph schumpeter sees entrepreneurs irrespective of class origin as heroic figures with the dream and will to found a private kingdom to conquer adversity to achieve success for its own sake and to experience the joy of creation for gustav papanek 1967 the private entrepreneur who is frugal diligent far sighted remarkably able and willing to take political risks is in large part responsible for the success of pakistan in achieving rapid industrialization

the effect of agriculture on repayment efficiency a look at mfi borrowing groups there is a widely held industry assumption from microfinance institutions that agricultural loans have poorer repayment rates which has resulted in many loans being provided for small businesses as opposed to agricultural purposes using data from a sample of 100 borrowing groups from a south indian microfinance institutions mfi this study challenges this belief by analyzing the repayment efficiency of borrowing groups and reflects on the implications for agricultural microfinance loans the analysis is run using bayesian stochastic frontier estimation with an exponential hierarchical prior on the efficiency term our results indicate that the average efficiency of the borrowing groups analyzed was approximately 75 and that having a higher percentage of agricultural loans increased borrowing group efficiency while gains in efficiency also rose as the size of the borrowing group increases

intergenerational social choice without the pareto principle a concise proof of wilson s theorem for a finite or countable set of individuals is presented a social welfare function satisfying nonimposition and arrow s independence axiom is either null or dictatorial if the set of individuals is infinite then continuity of social preference must be added to the hypothesis in which case the independence axiom alone implies that the social welfare function is either constant or dictatorial

microfinance mission drift summary claims have been made that microfinance institutions mfis experience mission drift as they increasingly cater to customers who are better off than their original customers we investigate mission drift using average loan size as a main proxy and the mfis lending methodology main market and gender bias as further mission drift measures we employ a large data set of rated multi country mfis spanning 11 years and perform panel data estimations with instruments we find that the average loan size has not increased in the industry as a whole nor is there a tendency toward more individual loans or a higher proportion of lending to urban costumers regressions show that an increase in average profit and average cost tends to increase average loan and the other drift measures more focus should be given to cost efficiency in the mfi

the isomorphism hypothesis the prisoner s dilemma as intertemporal allocation and vice versa abstract economists model the choice of the current self in intertemporal allocation as the outcome of identity the current and future selves belong to the same decision maker by the sheer fact they reside in the same biological skin defined by biological identity the economists should be consistent and likewise model the choice of each player in the prisoner s dilemma or generally the social dilemma as the outcome of identity the selves of the players belong to the same decision maker by the sheer fact they reside in the same social skin defined by social identity if the economists consider cooperation rather than defection to be the rational strategy of the current self in intertemporal allocations they should be consistent and consider cooperation rather than defection to be the rational strategy of each player in social dilemmas symmetrically if the economists judge defection rather than cooperation to be the rational strategy in social dilemmas it behooves them to also judge defection rather than cooperation to be the rational strategy in intertemporal allocations

the design of successful rural financial intermediaries evidence from indonesia abstract the success outreach and sustainability of eight rural financial intermediation systems in indonesia in profitably reaching large numbers of small individual clients is explained in terms of organizational design networks of semiautonomous units use local information and contract enforcement mechanisms to lower transaction costs reflecting basic concerns with institutional and financial viability elements of mechanism design have included compatible incentives such as performance based compensations profit sharing collection fees efficiency wages equivalent to quasi equity and system monitoring managerial discretion over transactions conducted at market terms policies to protect portfolio value and no dependency creating subsidies are important interventions have been appropriate for the problem at hand

the hazards of piecemeal reform british civil courts and the credit market in colonial india abstract the colonial experience of developing countries provides valuable evidence regarding the impact of legal and institutional innovations on economic growth however there has been little effort by economists to study colonial policies to gain theoretical insights into the process of institutional reform this paper considers the introduction of civil courts in colonial india and its impact on agricultural credit markets in the bombay deccan drawing on historical records and a formal analysis of the credit market the paper finds that the reform led to increased competition among lenders ex ante we expect that this would have raised farmers welfare but increased competition also reduced lenders incentives to subsidize farmers investments in times of crisis leaving them more vulnerable in bad times

the profit orientation of microfinance institutions and effective interest rates summary with the rise in the number of for profit microfinance institutions mfis commentators are asking whether the sector benefits by mfis having stronger profit orientations we address this question by analyzing the relationship between interest rates and adopting the for profit legal form appointing private sector representation and traditional banking experience to advisory boards and participating in more extensive for profit networks the results consistently indicate that a stronger for profit orientation corresponds with higher interest rates for mfi clients however this does not contribute to greater profitability and therefore sustainability because the stronger profit orientation is also associated with higher mfi costs

access to capital in rural thailand an estimated model of formal versus informal credit the aim of this paper is to understand the mechanism underlying access to credit the author focuses on two important aspects of rural credit markets in thailand first moneylenders and other informal lenders coexist with formal lending institutions such as government or commercial banks and more recently micro lending institutions second potential borrowers presumably face sizable transaction costs obtaining external credit the author develops and estimates a model based on limited enforcement and transaction costs that provides a unified view of those facts the results show that the limited ability of banks to enforce contracts more than transaction costs is crucial in understanding the observed diversity of lenders

a dual self model of impulse control we propose that a simple dual self model gives a unified explanation for several empirical regularities including the apparent time inconsistency that has motivated models of quasi hyperbolic discounting and rabin s paradox of risk aversion in the large and small the model also implies that self control costs imply excess delay as in the o donoghue and rabin models of quasi hyperbolic utility and it explains experimental evidence that increased cognitive load makes temptations harder to resist the base version of our model is consistent with the gul pesendorfer axioms but we argue that these axioms must be relaxed to account for the effect of cognitive load

no profitable decompositions in quasi linear allocation problems abstract we study the problem of allocating a bundle of perfectly divisible private goods from an axiomatic point of view in situations where compensations can be made through monetary transfers the key property we impose on the allocation rule requires that no agent should be able to gain by decomposing the problem into sequences of subproblems combined with additional standard properties it leads to a characterization of the rule that shares the total surplus equally hence a traditional welfarist rule emerges as the unique consequence of our axioms phrased in a natural economic environment

does the classic microfinance model discourage entrepreneurship among the poor experimental evidence from india do the repayment requirements of the classic microfinance contract inhibit investment in high return but illiquid business opportunities among the poor using a field experiment we compare the classic contract which requires that repayment begin immediately after loan disbursement to a contract that includes a two month grace period the provision of a grace period increased short run business investment and long run profits but also default rates the results thus indicate that debt contracts that require early repayment discourage illiquid risky investment and thereby limit the potential impact of microfinance on microenterprise growth and household poverty jel a21 g32 i32 l25 l26 o15 o16

financial performance and outreach a global analysis of leading microbanks microfinance contracts have proven able to secure high rates of loan repayment in the face of limited liability and information asymmetries but high repayment rates have not translated easily into profits for most microbanks profitability though is at the heart of the promise that microfinance can deliver poverty reduction while not relying on ongoing subsidy the authors examine why this promise remains unmet for most institutions using a data set with unusually high quality financial information on 124 institutions in 49 countries they explore the patterns of profitability loan repayment and cost reduction the authors find that institutional design and orientation matter substantially lenders that do not use group based methods to overcome incentive problems experience weaker portfolio quality and lower profit rates when interest rates are raised substantially for these individual based lenders one key to achieving profitability is investing more heavily in staff costs a finding consistent with the economics of information but contrary to the conventional wisdom that profitability is largely a function of minimizing cost

equity measurement in facility location analysis a review and framework abstract in selecting sites for facilities especially in the public sector the issue of equity is becoming increasingly important beginning with the work of mumphreys et al 1971 mcallister 1976 and savas 1978 a substantial literature has developed that incorporates equity in facility siting decision models despite this level of interest however there has been little agreement in these models as to how equity should be measured further except for some recent works there has generally been little comparison of alternative measures or assesment of their relative value let alone any consensus on the best measure s to use perhaps even more surprising is the great number and variety of measures employed the motivation for this paper is to address these problems and provide for researchers a base from which issues of equity can be included in facility siting models more specifically we seek to review the equity literature as it pertains to facility location assemble the set of measures that have been developed and introduce a framework and common notation for organizing them we also will discuss approaches that can be used to select an appropriate measure of equity

do irrelevant commodities matter we study the possibility of making social evaluations of allocations independently of individuals preferences over unavailable commodities this is related to the well known problem of performing international comparisons of standard of living across countries with different consumption goods we prove impossibility results which suggest that such evaluations encounter difficulties when the objects of evaluation are allocations of ordinary commodities we show how possibility results can be retrieved when the objects of evaluation are allocations of composite commodities characteristics or human functionings

financial inclusion gender dimension and economic impact on poor households summary we examine the question in the context of gender dimension what is the evidence of the impact of the financial inclusion programs on poor households represented by women relative to that represented by men by constructing a good counterfactual and comparison group we employ the difference in difference estimator approach with panel least squares and generalized methods of moments using standard errors for a robust analysis we notice that income growth cagr net of inflation effect was 8 40 for women as against 3 97 for men indicating that the gender of participating poor undoubtedly affects the outcomes of these programs

the vulnerability of microfinance to financial turmoil evidence from the global financial crisis summary has microfinance become crisis prone like other sources of finance this paper provides empirical evidence on credit growth patterns of microfinance institutions in the early 2000s results suggest that microfinance has become vulnerable to financial turmoil in the global financial crisis credit growth dropped sharply moreover the crisis impact was more severe when institutions had been active in tapping domestic and international financial markets for funds and had operated in countries experiencing a severe post crisis recession finally we find that microcredit adopted the cyclical characteristics of credit growth in the traditional banking sector with credit booms followed by credit busts

rational herding toward the poor evidence from location decisions of microfinance institutions within pakistan analyzing the geographical location of almost all the microfinance institutions mfis within pakistan this paper gives further evidence that microfinance activities do not reach the poorest rural areas especially we explore how this result is driven by the uncertainty faced by mfis in their location decision i e they can hardly predict accurately whether or not they will perform financially furthermore we find that mfis are spatially clustered and identify three main reasons for this common attraction factors i e the characteristics of one area fits to the preferences of all mfis so that they are all located in the same areas payoff externalities to be collocated and herd behavior i e mfis follow one another most importantly we find that a significant part of this herding process is rational i e early locations of mfis convey information used by later ones such that it reverses or neutralizes the negative impact of uncertainty resulting then in more locations in needier areas since it allows them to be located in poorer areas mfis improve the achievement of their social goal this latter result is rather good news for those who reckon that a better access to financial services enhances economic growth and fosters poverty alleviation indeed rational herding constitutes an endogenous moderator effect to the big issue that financial services penetration is too weak in the poorest rural areas

equally distributed equivalent utility ex post egalitarianism and utilitarianism we provide an axiomatization of expected equally distributed equivalent utility social welfare functions in the context of harsanyi s impartial observer theorem for this family of social welfare functions we show what additional axiom is necessary and sufficient for the observer to exhibit aversion to ex post inequality we also relate this axiomatization to our axiomatization in a companion paper of generalized utilitarian social welfare functions given certain richness assumptions the only social welfare functions that belong to both families are the utilitarian

ownership and technical efficiency of microfinance institutions empirical evidence from latin america by using stochastic frontier analysis this article examines the technical efficiency of different types of microfinance institutions in latin america in particular it tests whether differences in technical efficiency both intra and interfirm can be explained by differences in ownership with a focus on non governmental organizations cooperatives and credit unions non bank financial intermediaries and banks the data set contains 1681 observations from a panel of 315 institutions operating in 18 latin american countries the results show that non governmental organizations and cooperatives have much lower interfirm and intrafirm technical efficiencies than non bank financial intermediaries and banks which indicates the importance of ownership type for technical efficiency

intensifying financial inclusion through the provision of financial literacy training a gendered perspective this study examines the impact of financial literacy training on financial inclusion and its intensity using data collected from a randomised control trial an additive index of financial inclusion

aggregate risk and the pareto principle abstract in the evaluation of public policies a crucial distinction is between plans that involve purely idiosyncratic risk and those that generate correlated or aggregate risk while natural this distinction is not captured by standard utilitarian aggregators in this paper we revisit harsanyi s 1955 celebrated theory of preferences aggregation and develop a parsimonious generalization of utilitarianism the theory we propose captures sensitivity to aggregate risk in large populations and can be characterized by two simple axioms of preferences aggregation

social welfare functions for economic environments with and without the pareto principle it is shown for the case of private goods economies that every social welfare function satisfying a weak nonimposition condition and the independence of irrelevant alternatives axiom is of one of the following forms it is either null or the class of decisive coalitions is an ultrafilter or the class of anti decisive coalitions is an ultrafilter in the case of a private goods economy with finitely many traders the latter conditions imply the existence of either a dictator or anti dictator by requiring the pareto principle as well it is easily seen that the social welfare function must be dictatorial

the challenge of rural financial inclusion evidence from microfinance financial inclusion is said to foster development and growth however progress in financial inclusion has been slow in rural areas where poverty is most pronounced this is often attributed to hig

financial efficiency and social impact of microfinance institutions using self organizing maps summary this paper contributes to the literature by investigating whether the increased focus on financial self sustainability of microfinance institutions has been disadvantageous to the target audience we investigate the association between social efficiency and financial performance using a comprehensive data set that includes 650 microfinance institutions a self organizing map methodology is used to fully capture the existing heterogeneity among institutions the results show that we cannot support the hypothesis that there exists a trade off on the contrary we find evidence of a significant positive relationship between social efficiency and financial performance

outreach and performance of microfinance institutions a panel analysis using a panel of 764 microfinance institutions mfis from 87 countries this study analyses the possible trade off between outreach and performance and shows that greater depth of outreach has a positive impact on the financial performance of an mfi the empirical results of this study should dispel the widely held apprehension that the recent emphasis on attainment of financial sustainability by the mfis could seriously impair their outreach efforts and shows that outreach to the poor can actually bolster financial performance

let s agree that all dictatorships are equally bad this paper shows that a minimal degree of consideration for other people s well being enables society to agree that one social policy is the best i offer axioms that imply that this best policy maximizes a weighted sum of individual utilities the weight of each individual is the inverse of his or her maximal possible utility from social endowments the suggested policy is not sensitive to the choice of the von neumann morgenstern utilities the key axiom is that individuals agree that giving all the endowments always to one person is as bad as giving them to any other person

on the efficiency effects of subsidies in microfinance an empirical inquiry summary using an original database of rating agencies this paper gives empirical evidence on the impact of subsidy intensity on the efficiency of microfinance institutions mfis we find that subsidies have had a positive impact on efficiency in the sense that mfis that received subsidies are more efficient than those that do not however we find also that subsidization beyond a certain threshold renders the marginal effect on efficiency negative in our sample 26 of mfis receive levels of subsidization higher than that threshold which implies that a marginal cut on subsidy intensity would increase their efficiency

transitive social choice in economic environments assume a finite society a standard space of allocations of private goods and a domain of profiles of classical economic preferences if social preference is expressed as a continuous preorder then a social welfare function satisfies arrow s independence axiom if and only if it is constant or completely authoritarian an authoritarian rule is one that is either dictatorial or inversely dictatorial copyright 1992 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

nudging farmers to use fertilizer theory and experimental evidence from kenya we model farmers as facing small fixed costs of purchasing fertil izer and assume some are stochastically present biased and not fully sophisticated about this bias such farmers may procrastinate post poning fertilizer purchases until later periods when they may be too impatient to purchase fertilizer consistent with the model many farmers in western kenya fail to take advantage of apparently profit able fertilizer investments but they do invest in response to small time limited discounts on the cost of acquiring fertilizer free deliv ery just after harvest calibration suggests that this policy can yield higher welfare than either laissez faire policies or heavy subsidies

self control and the theory of consumption to study the behavior of agents who are susceptible to temptation in infinite horizon consumption problems under uncertainty we define and characterize dynamic self control dsc preferences dsc preferences are recursive and separable in economies with dsc agents equilibria exist but may be inefficient in such equilibria steady state consumption is independent of initial endowments and increases in self control increasing the preference for commitment while keeping self control constant increases the equity premium removing nonbinding constraints changes equilibrium allocations and prices debt contracts can be sustained even if the only feasible punishment for default is the termination of the contract

practice what you preach microfinance business models and operational efficiency the microfinance sector has room for pure for profit microfinance institutions mfis non profit organizations and social for profit firms that aim to pursue a double bottom line depending on their business model these institutions target different types of borrowers change the size of their loans and adjust their loan pricing we introduce a simple approach that accommodates a wide range of business models and allows us to estimate the operational efficiency of mfis our empirical results show that mfis with a high depth of outreach are most efficient resulting in higher levels of outreach and profits for the same input mix

arrovian theorems with private alternatives domains and selfish individuals abstract this paper proves that the impossibility theorems of arrow wilson and mas colell and sonnenschein hold if the individual preferences domains are hypersaturating for hypersaturating domains the set of social states has the structure of a cartesian product of sets of private alternatives individuals are selfish and the domain satisfies some further restrictions consumption sets are examples of hypersaturating domains when the individual preferences are continuous convex and monotonic but many other examples make hypersaturating domains meaningful for the analysis of problems involving private alternatives sets incidentally all the theorems hold for the case of divisible public goods

can equity be purchased at the expense of efficiency an axiomatic inquiry abstract assume the restricted domain of classical welfare economics the pareto rule ranks x strictly above y if and only if everyone strictly prefers x to y suppose the social welfare function satisfies 1 nonimposition 2 independence of irrelevant alternatives 3 continuity and quasitransitivity of social preference 4 minimal equity there is at least one situation in which at least one social optimum gives each individual a positive amount of at least one commodity then agrees with the pareto rule except perhaps for comparisons in which someone is assigned the zero vector and the pareto rule is at least as decisive as overall

do microfinance institutions accomplish their mission evidence from the relationship between traditional financial sector development and microfinance institutions outreach and performance this article analyses the relationship between outreach and performance of microfinance institutions mfis on the one hand and traditional financial sector development on the other the results indicate that mfis reach more clients and are more profitable in countries where access to the traditional financial system is low this finding is in line with the market failure hypothesis mfis respond to a need that banks do not fulfill and mfis flourish where the formal financial sector fails along the same line the results demonstrate that mfis serve poorer people in countries with well developed financial systems the results suggest that in countries with well developed financial systems the two sectors stand in more direct competition with each other this competition pushes mfis down the market and makes mission drift by mfis less likely

assessing risky social situations this paper reexamines the welfare economics of risk it singles out a class of criteria the expected equally distributed equivalent as the unique class that avoids serious drawbacks of existing approaches such criteria behave like ex post criteria when the final statistical distribution of well being is known ex ante and like ex ante criteria when risk generates no inequality the paper also provides a new result on the tension between inequality aversion and respect of individual ex ante preferences in the vein of harsanyi s aggregation theorem

which microfinance institutions are becoming more cost effective with time evidence from a mixture model italian speakers tend to stress the second component of german morphologically complex words such as compounds and prefix verbs even if the first component is lexically stressed to improve their prosodic phrasing an automatic pronunciation teaching method was developed based on auditory feedback of prosodically corrected utterances in the learners own voices basically the method copies contours of f0 local speech rate and intensity from reference utterances of a german native speaker to the learners speech signals it also adds emphasis to the stress position in order to help the learners better recognise the correct pronunciation and identify their errors a perception test with german native speakers revealed that manipulated utterances significantly better reflect lexical stress than the corresponding original utterances thus two groups of italian learners of german were provided with different feedback during a training session one group with manipulated utterances in their individual voices and the other with correctly pronounced original utterances in the teacher s voice afterwards both groups produced the same sentences again and german native speakers judged the resulting utterances resynthesised stimuli especially with emphasised stress were found to be a more effective feedback than natural stimuli to learn the correct stress position since resynthesis was obtained without previous segmentation of the learners speech signals this technology could be effectively included in computer assisted language learning software

present bias lessons learned and to be learned while present bias is an old idea it only took hold in economics following david laibson s 1994 dissertation over the past 20 years research has led to a much better theoretical understanding of present bias when and how to apply it and which ancillary assumptions are appropriate in different contexts empirical analyses have demonstrated how present bias can improve our understanding of behavior in various economic field contexts nonetheless there is still much to learn in this paper we give our assessment of some lessons learned and to be learned

catastrophe aversion and risk equity in an interdependent world catastrophe aversion and risk equity are important concepts both in risk management theory and practice keeney keeney rl 1980 equity and public risk oper res 28 3 527 534 was the first to formally define these concepts he demonstrated that the two concepts are always in conflict yet his result is based on the assumption that individual risks are independent it has therefore limited relevance for real world catastrophic events we extend keeney s result to dependent risks and derive the conditions under which more equity and more correlation between two risks imply a more catastrophic situation we then generalize some of the results for multiple correlated risks this paper was accepted by manell baucells decision analysis

can microfinance reach the poorest evidence from a community managed microfinance intervention summary reaching the poorest is an important objective in many development interventions and microfinance is no exception we review performance indicators for effectiveness of targeting described in the literature and suggest a new metric in order to account for extent and severity of poverty as well as the income distribution among the poor when applying this to a panel dataset from a community managed microfinance intervention in northern malawi we find regressive targeting participants are less poor than the general population in the area in addition we provide suggestions as to when and why the poor exit the project

do rural banks matter evidence from the indian social banking experiment lack of access to finance is often cited as a key reason why poor people remain poor this paper uses data on the indian rural branch expansion program to provide empirial evidence on this issue between 1977 and 1990 the indian central bank mandated that a commercial bank can open a branch in a location with one or more bank branches only if it opens four in locations with no bank branches we show that between 1977 and 1990 this rule caused banks to open relatively more rural branches in indian states with lower initial financial development the reverse is true outside this period we exploit this fact to identify the impact of opening a rural bank on poverty and output our estimates suggest that the indian rural branch expansion program significantly lowered rural poverty and increased non agricultural output

altruism in the family and selfishness in the market place adam smith argued in a famous passage that people are selfish in their market transactions it is not from the benevolence of the butcher the brewer or the baker that we expect our dinner but from their regard to their own interest we address ourselves not to their humanity but to their self love and never talk to them of our own necessities but of their advantages 1937 p 14 in an earlier study he said with irony we are not ready to suspect any person of being defective in selfishness 1853 p 446 selfishness in market transactions has been assumed in practically all subsequent discussions of the economic system objections were dismissed with vague allusions to human nature or with an assertion that altruism loses out to selfishness in the struggle to survive in the market sector yet altruism is generally recognized to be important within a family again adam smith said
