The Economics of Microfinance

Abstract: The microfinance revolution, begun with independent initiatives in Latin America and South Asia starting in the 1970s, has so far allowed 65 million poor people around the world to receive small loans without collateral, build up assets, and buy insurance. This comprehensive survey of microfinance seeks to bridge the gap in the existing literature on microfinance between academic economists and practitioners. Both authors have pursued the subject not only in academia but in the field; Beatriz Armendariz founded a microfinance bank in Chiapas, Mexico, and Jonathan Morduch has done fieldwork in Bangladesh, China, and Indonesia. The authors move beyond the usual theoretical focus in the microfinance literature and draw on new developments in theories of contracts and incentives. They challenge conventional assumptions about how poor households save and build assets and how institutions can overcome market failures. The book provides an overview of microfinance by addressing a range of issues, including lessons from informal markets, savings and insurance, the role of women, the place of subsidies, impact measurement, and management incentives. It integrates theory with empirical data, citing studies from Asia, Africa, and Latin America and introducing ideas about asymmetric information, principal-agent theory, and household decision making in the context of microfinance. The Economics of Microfinance can be used by students in economics, public policy, and development studies. Mathematical notation is used to clarify some arguments, but the main points can be grasped without the math. Each chapter ends with analytically challenging exercises for advanced economics students.

Microfinance Beyond Group Lending

Abstract: Microlending is growing in Eastern Europe, Russia and China as a flexible means of widening access to financial services, both to help alleviate poverty and to encourage private-sector activity We describe mechanisms that allow these programmes to successfully penetrate new segments of credit markets These features include direct monitoring, regular repayment schedules, and the use of non-refinancing threats These mechanisms allow the programmes to generate high repayment rates from low-income borrowers without requiring collateral and without using group lending contracts that feature joint liability

The Economics of Microfinance, Second Edition

Abstract: The microfinance revolution has allowed more than 150 million poor people around the world to receive small loans without collateral, build up assets, and buy insurance. The idea that providing access to reliable and affordable financial services can have powerful economic and social effects has captured the imagination of policymakers, activists, bankers, and researchers around the world; the 2006 Nobel Peace Prize went to microfinance pioneer Muhammed Yunis and Grameen Bank of Bangladesh. This book offers an accessible and engaging analysis of the global expansion of financial markets in poor communities. It introduces readers to the key ideas driving microfinance, integrating theory with empirical data and addressing a range of issues, including savings and insurance, the role of women, impact measurement, and management incentives. This second edition has been updated throughout to reflect the latest data. A new chapter on commercialization describes the rapid growth in investment in microfinance institutions and the tensions inherent in the efforts to meet both social and financial objectives. The chapters on credit contracts, savings and insurance, and gender have been expanded substantially; a new section in the chapter on impact measurement describes the growing importance of randomized controlled trials; and the chapter on managing microfinance offers a new perspective on governance issues in transforming institutions. Appendixes and problem sets cover technical material.

On Mission Drift in Microfinance Institutions

Abstract: This paper sheds light on a poorly understood phenomenon in microfinance which is often referred to as a “mission drift”: A tendency reviewed by numerous microfinance institutions to extend larger average loan sizes in the process of scaling–up. We argue that this phenomenon is not driven by transaction cost minimization alone. Instead, poverty–oriented microfinance institutions could potentially deviate from their mission by extending larger loan sizes neither because of “progressive lending” nor because of “cross–subsidization” but because of the interplay between their own mission, the cost differentials between poor and unbanked wealthier clients, and region-specific characteristics pertaining the heterogeneity of their clientele. In a simple one-period framework we pin-down the conditions under which mission drift can emerge. Our framework shows that there is a thin line between mission drift and cross-subsidization, which in turn makes it difficult for empirical researchers to establish whether a microfinance institution has deviated from its poverty-reduction mission. This paper also suggests that institutions operating in regions which host a relatively small number of very poor individuals might be misleadingly perceived as deviating from their mission. Because existing empirical studies cannot tear apart between mission drift and cross-subsidization, these studies should not guide donors and socially responsible investors pertaining resource allocation across institutions offering financial services to the poor. The difficulty in tearing apart cross-subsidization and mission drift is discussed in light of the contrasting experiences between microfinance institutions operating in Latin America and South Asia.

The microfinance promise

Abstract: 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.

Precautionary Saving in the Small and in the Large

Abstract: The theory of precautionary saving is shown in this paper to be isomorphic to the Arrow-Pratt theory of risk aversion, making possible the application of a large body of knowledge about risk aversion to precautionary saving, and more generally, to the theory of optimal choice under risk In particular, a measure of the strength of precautionary saving motive analogous to the Arrow-Pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving, and to give a new interpretation of the Oreze-Modigliani substitution effect

Rediscovering Social Innovation

Abstract: In the spring of 2003, the Center for Social Innovation at the Stanford Graduate School of Business launched the Stanford Social Innovation Review. Our first “Editors’ Note” defined social innovation as “the process of inventing, securing support for, and implementing novel solutions to social needs and problems.” That same manifesto also described the publication’s unique approach to social innovation: “dissolving boundaries and brokering a dialogue between the public, private, and nonprofit sectors.”

Financial performance and outreach: a global analysis of leading microbanks*

Abstract: 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.
