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

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

economic implications of intergenerational equity for biodiversity conservation the rights of future generations to enjoy sustainable development have been formally recognised internationally this has important implications for the economic analysis of biological diversity which as an integral attribute of natural capital is of critical importance to both current and future generations the dominant economic paradigm involves no explicit recognition of the rights of future generations thus it can give rise to outcomes of dubious intergenerational equity merit rawls contractarian theory attributes intrinsic value to rights and is considered here in relation to the intergenerational distribution of natural resources some problems of theoretical and practical character for the implementation of the rawlsian approach are noted an incremental and adaptive learning process in the use and distribution of natural resources is recommended in order to ensure the well being of future generations three degrees of intergenerational equity are derived i extensive ii intermediate and iii minimal in terms of biodiversity conservation this implies an ethical base for countries to at least fund the establishment of protected area pa systems therefore economic analysis should not be used at this conceptual level to decide if pa systems should or should not be established this question would necessarily be answered in the affirmative on the basis of the interests of future generations at the practical level of deciding which specific ecosystems should make up particular pa systems economic analysis should a contribute to a holistic approach to the identification of the areas to be protected b investigate the most cost effective way of carrying out the initiative c assess of the intragenerational equity outcomes and d consider the institutional features relevant to the successful implementation of the conservation initiative

does microcredit increase household welfare in the absence of microinsurance summary this study answers the question does a combination of microcredit and microinsurance improve the wellbeing of low income households we examine this challenge through heckman sample selection instrumental variable and treatment effect models the findings indicate that households using microcredit in combination with microinsurance derive significant gains in terms of welfare improvement microcredit may be good but its benefit to the poor is enhanced and sustained if the poverty trapping risks are covered with microinsurance to this extent combining microcredit with microinsurance will empower the poor to make a sustainable exit from poverty

weighing what s practical proxy means tests for targeting food subsidies in egypt abstract despite achieving a significant cost reduction over the past two decades the absolute cost of food subsidies in egypt is still high relative to the benefits received by the poor there is scope for better targeting these food subsidies in particular for targeting cooking oil and sugar ration cards both because reforms in this area are perceived to be far less politically sensitive than adjusting subsidy policy for bread and wheat flour and because higher income groups presently receive a significant percentage of the benefits targeting the high subsidy green ration cards to the poor and the low subsidy red ration cards to the nonpoor will require identification of both poor and nonpoor households an international food policy research institute research team in egypt in collaboration with the egyptian ministry of trade and supply developed a proxy means test for targeting ration cards the paper describes the process of moving from the optimal income predicting model to the final model that was both administratively and politically feasible an ex ante evaluation of the levels of accuracy of the proxy means testing model indicates that the model performs quite well in predicting the needy and nonneedy households an effective and full implementation of this targeting method would increase the equity in the ration card food subsidy system and at the same time the total budgetary costs of rationed food subsidies would decline moreover the experience gained under this reform would facilitate targeting future social interventions to reduce and prevent poverty in egypt

the rainforest supply price a tool for evaluating rainforest conservation expenditures abstract economic policies are often suggested as mechanisms for promoting rainforest conservation in developing countries to help decide whether international resources should be used to protect specific rainforests the calculation of a rainforest supply price rsp is proposed korup national park in cameroon contains the oldest rainforest in africa and as a haven for important endangered species it is the subject of active international conservation efforts a cost benefit analysis of a conservation project to protect korup from increased land use pressures suggests that it is not in cameroon s interest unless a 5 4 million ecu inducement is transferred to cameroon given the protection afforded the transfer is equivalent to a rsp of 1060 ecu per km2 per year evaluations of six other tropical rainforest projects suggest that international donors made transfers having values ranging from 15 to 1575 ecu per km2 per year it is thus concluded that the inducements required are within a range that conservation interests are apparently willing to mobilize

employment creation and green development strategy employment creation has received surprisingly little attention in the literature on environmental economics this paper argues for closer ties between sustainable development and employment creating development at both the global and the national levels of planning and policy the paper briefly reports on the employment challenge confronting indonesia to highlight the jobs versus environment dilemma facing a developing country that is rich in natural resources but densely populated it is argued that the high income countries of the north should take the initiative in raising funds through ecotaxes levies on international trade and other appropriate income policies in order to increase investment flows for job creating development in the south to make sustainability a practical reality

group credit a means to improve information transfer and loan repayment performance information asymmetries plague credit markets in developing countries leading to selective rationing and market segmentation with adverse income distributional consequences for small borrowers data collected from the finca group credit programme in costa rica were used to study the viability and cost effectiveness of group credit as a means to transmit information on borrower creditworthiness groups that screened members and used local information had lower delinquency rates than those that did not however less than half the groups had positive rates of economic return suggesting that group lending may improve information flow but is a cost sensitive institutional design

exposure to intimate partner violence and repayment of microcredit evidence from field experiments in bangladesh abstract this paper investigates the impact of intimate partner violence on poor women s repayment behavior in microcredit in a laboratory based field experiment we extended collateral free small loans to 485 currently married women in rural bangladesh and observed their repayment decisions over multiple loan cycles in a post experiment survey we asked subjects about their experience of spousal violence we find that women who experienced physical or sexual violence in the last 12 months are more likely to strategically default on their loans relative to those who did not experience such violence we conducted several robustness tests and the results suggest that the negative correlation between victimization and loan repayment rates is unlikely to be explained by selection into victimization non random underreporting of violence or the subjects attitude toward risk

social capital and coping with economic shocks an analysis of stunting of south african children abstract south african households live in an environment characterized by risks and many face a significant probability of experiencing economic losses that threaten their daily subsistence using household panel data that include directly solicited information on economic shocks and employing household fixed effects estimation we explore how well households cope with shocks by examining the effects of shocks on child nutritional status unlike in the idealized village community some households appear unable to insure against risk particularly when others in their communities simultaneously suffer large losses households in communities with more social capital however seem better able to weather shocks

a social and environmental approach to microfinance credit scoring microfinance institutions provide loans to low income individuals their credit scoring systems if they exist are strictly financial although many institutions consider the social and environmental impact of their loans they do not incorporate formal systems to estimate these social and environmental impacts this paper proposes that their creditworthiness evaluations should be coherent with their social mission and accordingly should estimate the social and environmental impact of microcredit thus a decision support system to facilitate microcredit granting is proposed using a multicriteria evaluation the assessment of social impact is performed by calculating the social net present value the system captures credit officers experience and addresses incomplete and intangible information the model has been tested in a microfinance institution the paper shows how a small institution can include social and environmental issues in its decision making systems to evaluate credit applications a gap in the preferences was found between members of the board who are socially driven and managers and credit officers who are financially drifted this mission drift was corrected the approach followed contributed to creating a culture of social and environmental assessment within the institution especially among credit officers thereby translating microfinance institutions social mission into numbers

the total economic value of amazonian deforestation 1978 1993 national income accounting has been criticized because of its failure to encompass the notion of sustainability several studies address this problem through green income accounting i e by adjusting conventionally measured gdp for reduction in a given country s stock of natural resources these studies generally base value on the unit net price of the resource other studies go beyond net price emphasizing a natural resource s total economic value tev that is its non marketable as well as its marketable values this paper combines the green income accounting and tev approaches and applies the new framework to brazil in order to assess the foregone economic benefits resulting from amazonian deforestation the results lend support to calls for greater policy emphasis on conservation of unique and irreplaceable ecosystems 2000 elsevier science b v all rights reserved

are women overrepresented among the poor an analysis of poverty in 10 developing countries abstract this paper presents new evidence on the proportion of women in poverty in 10 developing countries it compares poverty measures for males and females and for male and female headed households and investigates the sensitivity of these measures to the use of per capita and per adult equivalent units and different definitions of the poverty line while poverty measures are higher for female headed households and for females the differences are significant in only a fifth to a third of the datasets the contribution of female headed households to aggregate poverty is less than that of females due to the low population share of the former stochastic dominance analysis reveals that differences between male and female headed households and between males and females are often insignificant except for ghana and bangladesh where females are consistently worse off these results suggest that cultural and institutional factors may be responsible for higher poverty among women in these countries our results point to the need to analyze determinants of household income and consumption using multivariate methods and to give greater attention to the processes underlying female headship

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

using repayment data to test across models of joint liability lending theories rationalising joint liability lending are rich in implications for repayment rates we exploit this fact to test four diverse models we show that the models repayment implications do not always coincide for example higher correlation of output and borrowers ability to act cooperatively can raise or lower repayment depending on the model data from thai borrowing groups suggest that repayment is affected negatively by the joint liability rate ceteris paribus and social ties and positively by the strength of local sanctions and correlated returns further the relative fit of the adverse selection versus informal sanctions models varies by region

assessing farmers risk preferences and their determinants in a marginal upland area of vietnam a comparison of multiple elicitation techniques we examine the consistency of risk preference measures based on eight hypothetical elicitation methods and a lottery game applied to smallholder farmers in a marginal upland environment in vietnam using these measures we identify influencing factors of risk aversion via regression analysis whereby unlike previous studies we include several proxies of social capital such as social networks and norms data were collected from household heads and spouses separately in a random sample of 300 households although correlations between most of the various risk preference measures are all statistically highly significant most are weak on average respondents have a high degree of risk aversion and specific characteristics gender age idiosyncratic shocks education social norms network reliance with extended family and connections to local authorities are significant determinants of risk preferences across most elicitation methods whereas others the household s dependency ratio wealth and covariate shocks are significant in a few methods only the explanatory power of the models is limited indicating that other factors are likely to be of greater importance in determining risk preferences the results can help target safety nets encourage investments and lead to the development of more applicable methods for assessing risk preferences of smallholders in developing countries

estimating the costs of environmental protection in brazil abstract in this paper an effort is made to estimate the amounts of money the government of the state of sao paulo brazil must transfer to counties in which environmentally protected areas of any sort have been established by the state a methodology to estimate these transfers is proposed based on the potential loss of production in the protected areas and the corresponding amounts are calculated the results indicate that protecting 7 68 of the state s territory will cause a maximum decrease in its gdp of 0 05 the estimation of monetary values for environmental costs is of interest because it provides a basis for judgement among different environmental protection alternatives and between these and other investment projects

distribution of ecological entitlements implications for economic security and population movement abstract the concept of economic and environmental security is explored in a broad sense as a series of necessary entitlements to forest and other resources traditional measures of inequality such as the gini coefficient or the atkinson index of inequality which rely on measures of the distribution of formal cash income or wealth are regarded as flawed to the extent that they do not adequately reflect the value and distribution of access to non marketed goods and services an ecologically sensitive atkinson or gini index is proposed as a more relevant measure of inequality and of economic and environmental security to improve security policies must attempt to improve the value of these indices an empirical example is provided based on household survey data for 357 households in 24 villages in a rainforest zone of cameroon analyses of data relating to forest use incomes and demographics provides insights into the distribution of ecological entitlements across various income groups and into the impacts of these entitlements on economic and environmental security through measures related to population migration the empirical analysis demonstrates a number of important conclusions a use of ecologically adjusted indices provides a more complete picture of inequality inequality in the forest zone is less pervasive than traditional measures would have us believe b traditional forest entitlements contribute positively to reducing inequality and improving security and c income support programs targeted to conventional cash crops cocoa and coffee increase inequality and reduce security the analyses also demonstrate that when other economic factors have been taken into account population movement can be a useful indicator of environmental security an analysis of migration demographic and income patterns suggests that low population movement in this zone can be construed as an indicator of higher environmental security the analysis also provides direct evidence that a decline in ecological entitlements increases the probability of migration out of an area

microfinance and investment a comparison with bank and informal lending summary comparing the impact of different types of credit on households investment in bangladesh we find that loans from microfinance institutions are likely to be channeled toward non agricultural activities while both informal and bank lending are associated to a higher expenditure in agricultural inputs estimated effects are net of the differences in the amount borrowed interest rates and collateral results suggest that features which are specific to microfinance such as tight repayment schedules and land based eligibility rules may reduce the suitability of this source of funds for the farming sector

group insurance and lending with endogenous social collateral abstract we construct a dynamic model of self enforcing insurance provision and lending to a community of borrowers who are connected by risk sharing arrangements that are themselves subject to enforcement problems as in kocherlakota 1996 we show that an outside lender offering constant consumption contracts can earn a higher profit if he conditions his repeated interactions with each borrower on the history of his interactions with all the group members a joint liability contract rather than on his history with that borrower only individual liability contracts this result holds even in the absence of informational asymmetries the observation driving it is that with individual liability contracts a joint welfare maximizing group may prefer to have one or more group members default on their contracts so that the group can consume a mix of outside funds and the defaulters stochastic income one contribution of our work is to give precise economic content to the concept of social collateral as the per agent surplus from group risk sharing over autarky the group can deter its members from defaulting on their contracts with the principal by threatening to reduce that surplus

do women borrowers augment financial performance of mfis abstractthere is some consensus that depth of outreach and financial performance of microfinance institutions mfi are positively correlated a majority of microcredit borrowers are women and since the prevalence of female borrowers is even greater among the very poor there should be a positive correlation between female borrowers and financial performance most of the mfis target women as preferred borrowers however no study to date has investigated the relationship between targeting women and mfi s sustainability with respect to profitability and yield utilizing a panel of 892 mfis over a period of 10 years this study shows that increased proportion of women borrowers has a statistically significant positive impact on yield and financial performance of mfis consequently this article also analyses the implication as to whether female borrowers have better repayment rate than male borrowers

peer monitoring and credit markets a major problem for institutional lenders is ensuring that borrowers exercise prudence in the use of the funds so that the likelihood of repayment is enhanced one partial solution is peer monitoring having neighbors who are in a good position to monitor the borrower be required to pay a penalty if the borrower goes bankrupt peer monitoring is largely responsible for the successful financial performance of the grameen bank of bangladesh and of similar group lending programs elsewhere but peer monitoring has a cost it transfers risk from the bank which is in a better position to bear risk to the cosigner in a simple model of peer monitoring in a competitive credit market this article demonstrates that the transfer of risk leads to an improvement in borrowers welfare

social capital and loan repayment performance in northern vietnam this study analyses the effects of social capital on the loan repayment behavior of borrowers in vietnam in the context of agricultural economics an innovative data collection approach is used that originates from the field of sociology a personal network survey is carried out to measure the individual social capital of borrowers social capital variables are defined according to tie strength bonding bridging and social distance linking between the respondent and his her network member social capital has a significant and positive influence on the rescheduling of loans however we find no significant evidence for an effect of social capital on late payment of principal or interest

repayment performance in group based credit programs in bangladesh an empirical analysis abstract this paper analyzes the repayment rates of 128 credit groups belonging to three group based credit programs in bangladesh the association for social advancement asa the bangladesh rural advancement committee brac and the rangpur dinajpur rural service rdrs using tobit analysis specific tests are performed on the following hypothesized determinants group size size of loans degree of loan rationing enterprise mix within groups demographic characteristics social ties and status and occurrence of idiosyncratic shocks the paper concludes that if basic principles of prudential banking are adhered to repayment rates can be good even in poor and remote communities the important thing for financial institutions is to tailor services such that it becomes worthwhile for the poor to establish a profitable long term association in addition more freedom to members in the process of group formation is recommended

effects of union organization on strike incidence in eu companies the author reinvestigates the relationship between the organizational power of trade unions and strikes based on data from the european company survey 2009 ecs 2009 and the institutional characteristics of trade unions wage setting state intervention and social pacts ictwss database which include more than 5 000 firms across all 27 european union eu member states he shows that the incidence of strikes is higher in companies for which workplace union membership is high the number of workplace unions is high and unions dominate establishment level works councils these factors interact to affect strike incidence in addition the company level effects of union organization on strike incidence vary across countries these country differences can partially be explained by differences in national trade union systems such as decentralization and membership density

liability structure in small scale finance evidence from a natural experiment microfinance the provision of small individual and business loans has witnessed dramatic growth reaching over 150 million borrowers worldwide much of its success has been attributed to overcoming the challenges of information asymmetries in uncollateralized lending yet very little is known about the optimal contract structure of such loans there is substantial variation across lenders even within a particular setting this paper exploits a plausibly exogenous change in the liability structure offered by a microfinance program in india which shifted from individual to group liability lending the analysis finds compelling evidence that contract structure matters for the same borrower required monthly loan installments are 6 percent less likely to be missed under the group liability setting relative to individual liability in addition compulsory savings deposits are 19 percent less likely to be missed under group liability contracts

trust membership in groups and household welfare evidence from kwazulu natal south africa unfortunately these two literatures have remained largely unconnected the group and network literature concludes that participation has important economic benefits even when the stated function of the group is noneconomic in most cases however the mechanisms by which groups and networks achieve this are unclear the determinants of trust and participation in groups literature highlights the importance of income and social homogeneity what remains less understood is whether and how trust can be generated for example via participation in groups this article links the empirical literatures referenced above by exploring the relationship between membership in groups and trust specifically using longitudinal data from kwazulu natal province south africa we examine 1 the importance of trust in the decision to join groups 2 the subsequent ability of groups to generate trust and 3 the effect of group membership and trust on a measure of well being per capita household income in addition we disaggregate groups into financial and nonfinancial and we categorize trust in people by agent or actor therefore we can explore whether trust in different kinds of actors is important for participation in different kinds of groups and whether participation in different kinds of groups is important for generating trust in different kinds of actors excerpt

designing credit agent incentives to prevent mission drift in pro poor microfinance institutions abstract credit agents in microfinance institutions mfis must be given incentives to acquire information on potential borrowers and select them in accordance with the mfi s objectives we show that while giving incentives has no cost in for profit mfis it is costly in pro poor mfis when repayment and wealth are positively correlated a pro poor mfi cannot obtain the selection of poor clients in the proportion it wishes with incentives based solely on repayment it then becomes necessary to audit the share of very poor borrowers selected by an agent in order to provide the latter with adequate incentives when audit costs are large pro poor mfis may have to forego selection on wealth and use other targeting devices such as working in impoverished geographical locations driven by donor concerns with mission drift away from the poor audits on the wealth status of clients have been introduced at the level of mfis we show that introducing pro poor incentives requires extending such audits to the level of credit agents

rethinking the effects of microcredit on household welfare in cambodia abstractthis article analyses the effects of microcredit on household welfare in terms of household expenditure per capita in cambodia with data from the cambodia socio economic survey carried out in 2014 the analysis describes the effects via formal and informal lending sectors accounting for endogenous selection bias arising from unobserved factors and for structural differences between borrowers and non borrowers in terms of expenditure functions the findings suggest that microcredit in both sectors reduces household expenditure

do we really care about biodiversity this paper addresses from an economic perspective the issue of global biodiversity conservation it challenges the perception that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock of natural capital despite the existence of a plethora of international agreements there still seems to be a global deficit of care surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation more light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for biodiversity conservation however actual expenditures are much lower than willingness to pay estimates recorded in the published literature using the criteria that the right amount of conservation effort is one where the marginal economic benefits from conservation just equal the marginal costs of conservation the paper explores the biodiversity conservation conundrum and concluded that on the available evidence the world does not care too much about this natural capital stock and bequests to future generations
