ABSTRACT: We replicate and reanalyze the most influential study of microcredit impacts (Pitt and Khandker, 1998). That study was celebrated for showing that microcredit reduces poverty, a much hoped-for possibility (though one not confirmed by recent randomized controlled trials). We show that the original results on poverty reduction disappear after dropping outliers, or when using a robust linear estimator. Using a new program for estimation of mixed process maximum likelihood models, we show how assumptions critical for the original analysis, such as error normality, are contradicted by the data. We conclude that questions about impact cannot be answered in these data.

Michal Bauer, Julie Chytilová, and Jonathan Morduch. “Behavioral Foundations of Microcredit: Experimental and Survey Evidence from Rural India.” American Economic Review 102 (2), April 2012: 1118-1139.

ABSTRACT: We use experimental measures of time discounting and risk aversion for villagers in south India to highlight behavioral features of microcredit, a financial tool designed to reduce poverty and fix credit market imperfections. The evidence suggests that microcredit contracts may do more than reduce moral hazard and adverse selection by imposing new forms of discipline on borrowers. We find that, conditional on borrowing from any source, women with present-biased preferences are more likely than others to borrow through microcredit institutions. Another particular contribution of microcredit may thus be to provide helpful structure for borrowers seeking self-discipline.

Rajeev Dehejia, Heather Montgomery, and Jonathan Morduch. “Do interest rates matter?  Credit demand in the Dhaka Slums.”  Journal of Development Economics 47 (2), March 2012: 437 – 499.

ABSTRACT: “Best practice” in microfinance holds that interest rates should be set at profit-making levels, based on the belief that even poor customers favor access to finance over low fees. Despite this core belief, little direct evidence exists on the price elasticity of credit demand in poor communities. We examine increases in the interest rate on microfinance loans in the slums of Dhaka, Bangladesh. Using unanticipated between-branch variation in prices, we estimate interest elasticities from − 0.73 to − 1.04, with our preferred estimate being at the upper end of this range. Interest income earned from most borrowers fell, but interest income earned from the largest increased, generating overall profitability at the branch level.

ABSTRACT: This review puts a corporate finance lens on microfinance. Microfinance aims to democratize global financial markets through new contracts, organizations, and technology. We explain the roles that government agencies and socially minded investors play in supporting the entry and expansion of private intermediaries in the sector, and we disentangle debates about competing social and commercial firm goals. We frame the analysis with theory that explains why microfinance institutions serving lower-income communities charge high interest rates, face high costs, monitor customers relatively intensively, and have limited ability to lever assets. The analysis blurs traditional dividing lines between nonprofits and for-profits and places focus on the relationship between target market, ownership rights, and access to external capital.

ABSTRACT: Leading advocates for microfinance have put forward an enticing “win-win” proposition: microfinance institutions that follow the principles of good banking will also be those that alleviate the most poverty. This vision forms the core of widely-circulated “best practices,” but as a general proposition the vision is fully supported neither by logic nor by the available empirical evidence. Recognizing the limits to the win-win proposition is an important step toward reaching a more constructive dialogue between microfinance advocates that privilege financial development and those that privilege social impacts.

ABSTRACT: Many interesting economic hypotheses entail differences in behaviors of groups within a population, but analyses of pooled samples shed only partial light on underlying segmentations. Finite mixture models are considered as an alternative to methods based on pooling. Robustness checks using t-regressions and a Bayesian analogue to the likelihood ratio test for model evaluation are developed. The methodology is used to investigate pro-son bias in child health outcomes in Bangladesh. While regression analysis on the entire sample appears to wash out evidence of bias, the mixture models reveal systematic girl-boy differences in health outcomes.

ABSTRACT: In the competitive model, externalities lead to inefficiencies, and inefficiencies increase with the size of externalities. However, as argued by Coase, these problems may be mitigated in a decentralized system through voluntary coordination. We show how coordination is limited by the combination of two factors: respect for individual autonomy and the existence of private information. Together they imply that efficient outcomes can only be achieved through coordination when external effects are relatively large. Moreover, there are instances in which coordination cannot yield any improvement at all, despite common knowledge that social gains from agreement exist. This occurs when external effects are relatively small, and this may help to explain why coordination is so seldom observed in practice. When improvements are possible, we describe how simple subsidies can be used to implement second-best solutions and explain why standard solutions, such as Pigovian taxes, cannot be used. Possible extensions to issues arising in the structure of research joint ventures, assumptions in the endogenous growth literature, and the location of environmental hazards are also described.
