overcoming selection bias in microcredit impact assessments a case study in peru abstract there are several potential sources of bias in microcredit impact assessments this paper uses a panel data set from a peruvian mfi to test for impact of credit on microenterprise profits while controlling for these biases we find that those who will eventually become borrowers have significantly higher incomes than those who will not become borrowers implying that selection into the lending programme is a substantial problem after controlling for this selection we find that an average microentrepreneur who borrows earns significantly higher enterprise profits than one who does not borrow and that naive models which do not control for selection overestimate this impact fixed effects estimates give roughly the same results as the quasi experimental cross section analysis

specific experience household structure and intergenerational transfers farm family land and labor arrangements in developing countries data from indian rural household survey was used to test th hypothesis that the coexistence in traditional rural societies of extended intergenerational families infrequent land sales and high reliance on family members as farm laborers is the result of the economic advantages which accrue from the knowledge gained by farming a particular ploy of land over a long period of time the land specific experience of elderly members of a intergenerational household who farmed the land as a child and then as an adult are expecially critical in adverse weather years most previous investigators attributed the existence of multigenerational households the use of family members rather than hired laboreds and the infrequency of land sales to deficiencies in the market i e labor market imperfections and an absence of capital insurance and asset markets in the present investigations these same characteristics are viewed as having an economic advantages a model for estimating the contribution of the experience of the elderly household members to agricultural profits was developed and applied to data from a 3 year panel study of 2900 indian rural farm households the data was collected between 1968 71 by the national council of applied economic research the survey collected information on farm profits farm inputs demographic characteristics and the effects of weather conditions on profits a major limitation of the study was a lack of information on the duration of land ownership age of household members was substituted as a proxy for duration of ownership findings were consistent withe the hypothesis in poor agricultural years gross returns for households which contained an elderly household member were greater than the gross returns for comparable households which did not contain an elderly member the economic advantages of specific knowledge embodied in the experienced elderly farmer were comparable to the economic advantages which accrued to households whose members were more educated the hypothesis cannot fully explain the existence of intergenerational families since there is a relatively large proportion of such families among nonfarm families in many countries including india findings suggest that intergenerational families may provide for more occupational diversity and thereby reduce income risks the specific experience hypothesis has policy implications if technological changes are introduced the value of specific experience may be lost and the frequency of intergenerational households may decline the hypothesis may also explain why farmers are reluctant to agree to land redistribution and consolidation schemes this reluctance may disappear after sufficient technological change has occurred

regulating stock externalities under uncertainty abstract using a simple analytical model incorporating benefits of a stock costs of adjusting the stock and uncertainty in costs we uncover several important principles governing the choice of price based policies e g taxes relative to quantity based policies e g tradable permits for controlling stock externalities as in weitzman rev econom stud 41 4 1974 477 the relative slopes of the marginal benefits and costs of controlling the externality continue to be critical determinants of the efficiency of prices relative to quantities with flatter marginal benefits and steeper marginal costs favoring prices but some important adjustments for dynamic effects are necessary including correlation of cost shocks across time discounting stock decay and the rate of benefits growth applied to the problem of greenhouse gases and climate change we find that a price based instrument generates several times the expected net benefits of a quantity instrument

the impact of microcredit programs on self employment profits do noncredit program aspects matter microcredit programs provide a two tiered approach to poverty alleviation credit for the purchase of capital inputs in order to promote self employment and noncredit services and incentives these noncredit aspects may be an important component of the success of microcredit programs however because they are costly to deliver and their contribution to the success of the programs is difficult to measure they may not be properly valued this paper uses primary data on household participants and nonparticipants in grameen bank and two similar microcredit programs to measure the total and noncredit effects of microcredit program participation on productivity the total effect is measured by estimating a profit equation and the noncredit effect by estimating the profit equation conditional on productive capital productive capital and program participation are treated as endogenous variables in the analysis i find large positive effects of participation and the noncredit aspects of participation on self em

optimal mix of emissions taxes and cap and trade abstract in practice different emitters of a particular pollutant are sometimes subjected to different control mechanisms this paper focuses on the situation where a part of the economy is regulated by a cap and trade program while the rest is subjected to an emissions tax using an extended version of weitzman s prices vs quantities model m l weitzman prices vs quantities revi econ stud 41 1974 477 491 we analyze the conditions under which this is superior from an efficiency point of view to subjecting the whole economy to either of these control mechanisms the paper addresses a crucial trade off between two sources of efficiency loss one due to cost effectiveness issues and another due to emissions volume this trade off determines the optimal size of each sector it is shown that the size of the taxed sector at an optimum increases with the relative steepness of the aggregate marginal abatement cost function

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

how endowments accumulations and choice determine the geography of agricultural productivity in ecuador spatial disparity in incomes and productivity is apparent across and within countries most studies of the determinants of such differences focus on cross country comparisons or location choice among firms less studied are the large differences in agricultural productivity within countries related to concentrations of rural poverty for policy understanding the determinants of this geography of agricultural productivity is important because strategies to reduce poverty often feature components designed to boost regional agricultural incomes census and endowment data for ecuador are used to estimate a model of endogenous technology choice to explain large regional differences in agricultural output and factor productivity a composite error estimation technique is used to separate systemic determinants from idiosyncratic differences simulations are employed to explore policy avenues the findings suggest a differentiation between the types of policies that promote growth in agriculture generally and those that are more likely to assist the rural poor

where is the plus in credit plus the case of chiapas mexico abstractit has become common to try and increase the effectiveness of microfinance programmes by adding supplementary services to the financial product however the added value accruing from this credit plus approach has been little analysed we hypothesise that the extent of added value from credit plus depends on the ability of the credit supplier to cultivate trust or social capital amongst clients applying difference in difference estimation we exploit a natural experiment of two credit plus programmes in mexico the findings suggest that credit plus is not universally effective but that it is at its most effective especially with low income groups where bonding within group social capital exists

entrepreneurship selection and performance a meta analysis of the impact of education in developing economies this meta analytical review of empirical studies of the impact of schooling on entrepreneurship in selection and performance in developing economies looks at variations impact across specific characteristics of the studies a marginal year of schooling in developing economies raises enterprise income by an average of 5 5 percent which is close to the average return in industrial countries the return varies however by gender rural or urban residence and the share of agriculture in the economy furthermore more educated workers typically end up in wage employment and prefer nonfarm entrepreneurship to farming the education effect that separates workers into self employment and wage employment is stronger for women possibly stronger in urban areas and also stronger in the least developed economies where agriculture is more dominant and literacy rates are lower

agricultural household models extensions applications and policy this book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far the model assumes that households are price takers and is therefore recursive the decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor comparative results on selected elasticities are presented for a number of economies the empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive the book summarizes the implications of agricultural pricing policy for the welfare of farm households marketed surplus the demand for nonagricultural goods and services the rural labor market budget revenues and foreign exchange earnings in addition it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition nutritional status health saving and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings methodological topics primarily the data requirements of the basic model and its extensions along with aggregation market interaction uncertainty and market imperfections are discussed the most important methodological issues the question of the recursive property of these models is also discussed

who benefits the interactional determinants of microfinance s varied effects abstractsince its emergence as a development tool scholars and practitioners have questioned microfinance s short and long term impacts but have had insufficient empirical evidence to assess them to address this gap this paper draws on mixed method research to assess the effects of microfinance loan and educational services over time it explores why even within the same microfinance institution mfi some borrowers benefit from microfinance services more than others in the short term and examines how this translates into long term impacts the article identifies understudied sources of intra group variation the diversity and choices of borrowers and mfi employees interacting with each other and their broader contexts

status effects public goods provision and excess burden abstract most studies of the optimal provision of public goods or the excess burden from taxation assume that individual utility is independent of other individuals consumption this paper investigates public good provision and excess burden in a model that allows for interdependence in consumption in the form of status relative consumption effects in the presence of such effects consumption and labor taxes no longer are pure distortionary taxes but have a corrective tax element that addresses an externality from consumption as a result the marginal excess burden of consumption taxes is lower than in the absence of status effects and will be negative if the consumption tax rate is below the pigouvian rate correspondingly when consumption or labor tax rates are below the pigouvian rate the second best level of public goods provision is above the first best level contrary to findings from models without status effects for plausible functional forms and parameters relating to status effects the marginal excess burden from existing u s labor taxes is substantially lower than in most prior studies and is negative in some cases

prices versus quantities in a second best setting the choice between taxes and tradable permits has been independently analysed by two distinct research traditions the first proceeds from weitzman s partial equilibrium sto chastic model and concludes that a tax should be preferred if the marginal abatement cost curve is steeper than the marginal environmental benefit curve the second utilises deter ministic general equilibrium models with pre existing distortionary taxes it concludes that non revenue raising instruments e g grandfathered tradable permits are costlier than rev enue raising ones e g a tax on every unit of pollution or auctioned permits to build a bridge between these two traditions we introduce in weitzman s model a positive cost of public funds due to pre existing distortionary taxes the tax admits a greater comparative advantage over the permits as compared to weitzman s classical result then we assume that the regulated industry blocks any proposal that poses it too high an expected burden this may require a transfer to firms in the form of freely allocated permits or lump sum tax rebate it turns out that if this acceptability constraint is binding then the comparative advantage of taxes over permits is still reinforced quantitatively even if the marginal benefit function is 50 more steeply sloped than the marginal cost function the price instrument should be preferred we also compare the expected net benefit of these two instruments to a contingent instrument which leads to the ex post optimum the superiority of the contingent instrument over the quantity one is higher than in first best

complying with the kyoto protocol under uncertainty taxes or tradable permits the kyoto protocol allocates tradable emission allowances aaus to developed countries but they are free to choose a set of policy instruments to comply with these targets we compare two different policy instruments a tax and purely domestic tradable permits for the european union the us and japan information on abatement costs and international permit price is imperfect and stems from nine global economic models for a country party to the protocol the benefit of emission reduction is that it can sell more or has to buy less aaus we show that in this context permits entail a slightly lower expected cost than a tax for the us and japan whereas both instruments yield an almost equal outcome for europe applying weitzman s framework prices vs quantities res 1974 in this context we show the importance of the positive correlation between costs and benefits technology shocks that lead to low abatement costs in one country generally lead to low abatement costs in other countries too thereby leading to a low international permit price in the true up period

correlated uncertainty and policy instrument choice abstract for two decades environmental economists have generally maintained that benefit uncertainty is irrelevant for choosing between price and quantity instruments but that cost uncertainty matters with the identity of the efficient instrument depending upon the relative slopes of the marginal benefit and cost functions but in the presence of simultaneous correlated uncertainty such policy instrument recommendations may be inappropriate with plausible values of relevant parameters the conventional identification of a price instrument will be reversed to favor instead a quantity instrument the opposite reversal from the choice of a quantity instrument to a price instrument seems less likely to occur

optimal intensity targets for greenhouse gas emissions trading under uncertainty uncertainty is an obstacle for commitments under cap and trade schemes for emission permits we assess how well intensity targets where each country s permit allocation is indexed to its future realized gdp can cope with uncertainties in international greenhouse emissions trading we present some empirical foundations for intensity targets and derive a simple rule for the optimal degree of indexation to gdp using an 18 region simulation model of a cooperative global cap and trade treaty in 2020 under multiple uncertainties and endogenous commitments we show that optimal intensity targets could reduce the cost of uncertainty and achieve significant increases in global abatement the optimal degree of indexation to gdp would vary greatly between countries including super indexation in some advanced countries and partial indexation for most developing countries standard intensity targets with one to one indexation would also improve the overall outcome but to a lesser degree and not in all individual cases although target indexation is no magic wand for a future global climate treaty gains from reduced cost uncertainty and the potential for more stringent environmental commitments could justify the increased complexity and other potential downsides of intensity targets

money bonds and foreign exchange in the theory of finance capital markets provide securities which allow the ownership of productive assets to be allocated among investors according to their willingness to bear risk in exchange for return and independently of their tastes for the productive services provided by the assets this paper uses the theory of finance to study the role of money as a productive asset and the transformation of money into a portfolio asset true to its purpose the capital market provides securities nominal bonds that allow an allocation of the current services of the money supply according to its current productivity and without regard for its future purchasing power risk and an allocation of the future purchasing power risk of the money supply according to the willingness of investors to bear this risk in exchange for return and without regard for investor needs for the future transactions services of money in open

expanding credit access using randomized supply decisions to estimate the impacts expanding access to commercial credit is a key ingredient of financial development strategies there is less consensus on whether expanding access to consumer credit helps borrowers particularly when loans are extended at high interest rates popular skepticism about unproductive usurious lending is fueled by research highlighting behavioral biases that may induce overborrowing we estimate the impacts of expanding access to consumer credit at a 200 annual percentage rate apr using a field experiment and follow up data collection the randomly assigned marginal loans produced significant net benefits for borrowers across a wide range of outcomes there is also some evidence that the loans were profitable the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

can commercially oriented microfinance help meet the millennium development goals evidence from pakistan summary the current emphasis in the microfinance industry is a shift from donor funded to commercially sustainable operations this article evaluates the impact of access to microloans from the khushhali bank pakistan s first and largest microfinance bank which operates on commercial principles using primary data from a detailed household survey of nearly 3 000 borrower and non borrower households a difference in difference approach is used to test for the impact of access to loans once the results are disaggregated between rural and urban areas there is a positive impact in rural areas on food expenditure and on some social indicators such as the health of children and female empowerment these impacts are observed even in very poor households these findings suggest that commercially oriented microfinance and the millennium development goals are not incompatible given a supportive environment

high noon for microfinance impact evaluations re investigating the evidence from bangladesh recently microfinance has come under increasing criticism raising questions of the validity of iconic studies which have justified it such as pitt and khandker chemin applied propensity score matching to the pitt and khandker data finding different impacts but does not disaggregate by gender of borrower we first replicate chemin and extend his analysis in two ways we test the robustness of propensity score matching results to selection on unobservables using sensitivity analysis and we investigate propensity score matching estimates of impacts by gender of borrowers the mainly insignificant impacts of microfinance differ greatly by gender of borrower but are all vulnerable to selection on unobservables we are therefore not convinced that the relationships between microfinance and outcomes are causal with these data

is microcredit a blessing for the poor a meta analysis examining development outcomes and contextual considerations abstract increasing efforts aim at economic development and the reduction of poverty in developing countries through microcredit enabled entrepreneurship following the award of the nobel peace prize to prof yunus microcredit lending has risen to prominence and the volume of microcredit loans has increased substantially however theory on the outcomes of this financing form is controversial furthermore the academic community lacks conclusive empirical evidence about the impact of such programs primary empirical studies report fragmented and to a large extent contradictory results in this meta analysis we empirically synthesize a total of 545 quantitative empirical findings from 90 studies conducted to date our findings reveal a positive impact of microcredit on key development outcomes at the level of the client entrepreneurs additionally we scrutinize how the development context influences the effectiveness of microcredit and find that microcredit generally has a greater impact in more challenging contexts with our findings we contribute to research on the nexus of entrepreneurship and economic development and offer recommendations for practitioners and academics working on this promising frontier

how access to credit affects self employment differences by gender during india s rural banking reform abstract household survey data for 1983 2000 from india s national sample survey organisation are used to examine the impact of credit on self employment among men and women in rural labour households results indicate that credit access encourages women s self employment as own account workers and employers while it discourages men s self employment as unpaid family workers ownership of land a key form of collateral also serves as a strong predictor of self employment among the lower castes in india self employment is less likely for scheduled castes prone to wage activity but more likely for scheduled tribes prone to entrepreneurial work

combining price and quantity controls to mitigate global climate change abstract uncertainty about compliance costs causes otherwise equivalent price and quantity controls to behave differently and leads to divergent welfare consequences although most of the debate on global climate change policy has focused on quantity controls due to their political appeal this paper argues that price controls are more efficient simulations based on a stochastic computable general equilibrium model indicate that the expected welfare gain from the optimal price policy is five times higher than the expected gain from the optimal quantity policy an alternative hybrid policy combines both the political appeal of quantity controls with the efficiency of prices using an initial distribution of tradeable permits to set a quantitative target but allowing additional permits to be purchased at a fixed trigger price even sub optimal hybrid policies offer dramatic efficiency improvements over otherwise standard quantity controls for example a 50 trigger price per ton of carbon converts the 3 trillion expected loss associated with a simple 1990 emission target to a 150 billion gain these results suggest that a hybrid policy is an attractive alternative to either a pure price or quantity system

savings and nutrition at low incomes while many development theorists assume saving propensities vary among different groups there has been limited theoretical justification for this view this paper analyzes two complementary theories stressing the effect on saving of physiological consequences of poor nutrition at low incomes one influence is on the probability of survival another is on workers productivity either effect means that the average propensity to save can rise with income issues considered include annuities exogenous changes in survival and efficiency implications for the efficiency wage theory of unemployment and distinctions between wage and nonwage income implications of nutritional effects for econometric specification of saving functions are stressed

a reconsideration of sims evidence concerning monetarism abstract in var systems such as those of sims 1980 monetary policy surprises may be more accurately represented by interest rate than money stock innovations especially if the monetary authority uses an interest rate instrument

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

tax versus trading and efficient revenue recycling as issues for greenhouse gas abatement abstract we give empirical welfare results for global greenhouse gas emission abatement using the first multi party model to include both tax versus trading under uncertainties and revenue recycling including multiple independent parties greatly reduces the welfare advantage of an emissions tax over emissions permit trading in handling abatement cost uncertainties from that shown by existing single party literature but a previously ignored and much bigger advantage of a tax from better handling uncertainties in business as usual emissions greatly boosts the overall tax versus trading advantage yet the degree to which each mechanism is used to raise and recycle revenue efficiently by lowering distortionary taxes rather than recycle revenue as lump sums or not raise revenue by giving tax thresholds or free permits may in turn dominate any tax versus trading advantage choosing the best greenhouse abatement mechanism should thus consider the issues of tax versus trading and efficient revenue recycling together

household composition labor markets and labor demand testing for separation in agricultural household models this paper tests the separation of farm labor supply and labor demand decisions using the observation that household composition is an important determinant of farm labor use with nonseparation after assessing the conditions under which the test has power against several alternatives an empirical model is developed to test the proposition that farm employment is independent of family composition the model is estimated on a data set from rural java the null hypothesis that farm labor allocation decisions are independent of household structure is not rejected the results are robust to different specifications of the labor demand function copyright 1992 by the econometric society

medium and long term participation in microcredit an evaluation using a new panel dataset from bangladesh the objective of this paper is to estimate the impacts of medium and long term participation in microcredit programs it utilises a new and large panel dataset collected from treatment and control households from 1997 to 2005 the data enables us to identify continuing participants in the program as well as newcomers and leavers we employ different estimation strategies including triple difference and propensity score matching methods to control for selection bias the impact estimates indicate that the benefits from microcredit vary more than proportionately with the duration of participation in a program larger benefits are realized from longer term participation and that the benefits continue to accrue beyond departure from the program the findings indicate the need to observe longer periods of participation to provide a reliable basis for assessing the effectiveness of microcredit lending

causality and correlations of output and nominal variables in a real business cycle model abstract a dynamic general equilibrium economy in which output is exogenous with respect to money is calibrated and simulated following a procedure commonly used in the real business cycle literature it is then confronted with key comovement patterns of output and nominal variables in post war u s time series data the model economy performs well in matching second moment patterns involving output money and price the model economy with its embedded reverse causation from output to money also provides the means for carrying out a probabilistic appraisal of the observed money to output granger causality in u s data repeated applications of the granger causality test to simulated data lead to the rinding that money causes output more often than expected

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

the real impact of improved access to finance evidence from mexico this paper provides new evidence on the impact of access to finance on poverty it highlights an important channel through which access affects poverty the labor market the paper exploits the opening of banco azteca in mexico a unique natural experiment in which over 800 bank branches opened almost simultaneously in preexisting elektra stores importantly the bank has focused on previously underserved low income clients our key finding is a sizeable effect of access to finance on labor market activity and income levels especially among low income individuals and those located in areas with lower preexisting bank penetration

emission taxes and tradable permits a comparison of views on long run efficiency we compare three different views on the long runefficiencies of emission taxes which includethresholds inframarginalexemptions and of tradeable emission permitswhere some permits areinitially free the differences are caused bydifferent assumptions aboutwhether thresholds and free permits should besubsidies given only to firmsthat produce or full property rights treatingtax thresholds as well asfree permits as property rights would departfrom the conventional view but would allow greater flexibility in makingeconomic instruments bothefficient and acceptable such flexibilitycould be very important inachieving efficient control of greenhouse gasemissions

taxes and quotas for a stock pollutant with multiplicative uncertainty we compare taxes and quotas when firms and the regulator have asymmetric information about the slope of firms abatement costs damages are caused by a stock pollutant we calibrate the model using cost and damage estimates of greenhouse gasses taxes dominate quotas as with additive uncertainty this model with multiplicative uncertainty allows us to compare expected stock levels under the two policies and to investigate the importance of stock size and the magnitude of uncertainty on the policy ranking

consumers industrialists and the political economy of green taxation co2 taxation in oecd abstract economists have traditionally suggested that politicians should simply impose a uniform tax on harmful emissions as the first best solution prescribes however a detailed analysis of the actual design of green taxes in the oecd reveals that they are differentiated and far from this first best optimal design public choice theory suggests that an important reason that industry as a group in contrast to households is capable of lobbying against green taxation the paper presents empirical findings on co2 taxation within the oecd countries which confirm this theoretical prediction taxes are not uniform and households pay a tax rate which is six times higher than that paid by the industry on average even when tax revenue is fully refunded to industry the potential losers energy intensive firms will lobby harder against it than the potential winners labor intensive firms due to small group advantages the norwegian case confirms these arguments finally it is suggested that a co2 tax may perhaps successfully be applied to households because they tend to be badly organized as such a mix of green taxes in relation to non organized interests and grandfathered permit markets in relation to organized interests should be considered in the search for cost effective and politically feasible instruments

the role of economics in climate change policy many policy problems have frustratingly long histories of inefficient regulation that can be difficult or impossible to reverse even where large efficiency gains might be had from doing so climate change is an exception however because little real action has been undertaken to date it presents an unusual opportunity for an efficient economic policy to be employed right from the beginning however the opportunity could easily be lost ongoing negotiations conducted under the auspices of the united nations framework convention on climate change have so far produced the kyoto protocol a deeply flawed agreement that manages to be both economically inefficient and politically impractical in this article we examine the key economic characteristics of climate change and argue that economic theory provides good guidance on the design of an efficient and politically realistic policy because climate change involves vast uncertainties and has potentially enormous distributional effects neither of the standard market based environmental policy instruments is a viable approach a tradable permit system would be inefficient and an emissions tax would be politically unrealistic however a hybrid policy combining the best features of the two would be an efficient and practical approach we then compare our hybrid proposal to the kyoto protocol and argue that it overcomes the protocol s shortcomings

the impact of group based credit programs on poor households in bangladesh does the gender of participants matter this paper estimates the impact of participation by gender in the grameen bank and two other group based micro credit programs in bangladesh on labor supply schooling household expenditure and assets the empirical method uses a quasi experimental survey design to correct for the bias from unobserved individual and village level heterogeneity we find that program credit has a larger effect on the behavior of poor households in bangladesh when women are the program participants for example annual household consumption expenditure increases 18 taka for every 100 additional taka borrowed by women from these credit programs compared with 11 taka for men

non grant microfinance incentives and efficiency abstracti show that charging interest on funds provided by donors or investors to microfinance institutions mfis can increase efficiency the total number of loans and borrower welfare compared to grant or concessionary funding in a setting in which mfis supply costly non contractible effort putting a price or raising the price of loanable funds strengthens the mfis incentives to put effort in credit administration or monitoring to extend more loans and or reduce overhead costs this theoretical result is robust to several variations of the benchmark model allowing for an endogenous lending rate motivated mfis and endogenous overhead costs

transitional restricted linkage between emissions trading schemes linkages between emissions trading systems are deemed an important element of the future climate policy landscape they are however difficult to agree and remain few and far between temporary restrictions on permit trading have potential to facilitate and gradually approach unrestricted full linkage we compare the relative merits of several link restrictions in this respect namely quantitative transfer limits border taxes on transfers exchange and discount rates and unilateral linkage to this end we develop a simple model to have a unifying framework which in conjunction with lessons we draw from real world experiences serves as a basis for a broader policy oriented discussion while quantitative restrictions seem to be the natural route to full linkage they can lead to uncertain distributional effects and weaken price signals these aspects are mitigated under a border permit tax but this policy seems harder to implement exchange rates have potential to adjust for programmes stringencies and raise ambition over time but can be challenging to select as experience corroborates unilateral linkage can be a convenient approach

do microfinance institutions benefit from integrating financial and nonfinancial services this article examines the impact of microfinance plus i e coordinated combination of financial and nonfinancial services on the performance of microfinance institutions mfis using a global data set of mfis in 77 countries we find that the provision of nonfinancial services does not harm nor improve mfis financial sustainability and efficiency the results however suggest that the provision of social services is associated with improved loan quality and greater depth of outreach

behavioural and material determinants of production relations in agriculture in this essay we develop a framework for analysing the major institutions governing the production and exchange of output and the primary factors of production in rural areas the analysis incorporates general considerations of risk and information constraints jointly with the principal material attributes of agriculture and of agricultural production factors the framework is used to analyse barriers to the existence of the major intertemporal and factor markets it is applied specifically to land scarce environments for which it provides an internally consistent explanation for many of the well documented institutional features of such settings in addition the analysis provides new implications for among other phenomena the inter relationships among ownership holdings operational scale family size and factor productivity for the scarcity of animal rental markets and use of animals as collateral for the renting out of land by small landowners and for the existence of plantations for certain crops

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

gender differences in the impact of banking services evidence from mexico this paper examines the effects of providing financial services to low income individuals on entrepreneurial activity employment and the income levels of men and women we exploit cross time and cross municipality variation in the opening of banco azteca in mexico to measure these effects with a difference in difference strategy this bank opened over 800 branches simultaneously in 2002 focusing on low income clients our results show that this led to an increase in the number of informal business owners among men and to an increase in wage earning opportunities for women average income levels also increased with this increase being twofold higher for women than for men
