201. Credit Elasticities in Less-Developed Economies: Implications for Microcredit

Abstract:
Policymakers often prescribe that microfinance institutions increase interest rates to eliminate reliance on subsidies. This strategy makes sense if the poor are rate insensitive: then microlenders increase profitability (or achieve sustainability) without reducing the poor's access to credit. We test the assumption of price inelastic demand using randomized trials conducted by a consumer lender in South Africa. The demand curves are downward-sloping, and steep for price increases relative to the lender's standard rates. We also find that loan size is far more responsive to changes in loan maturity than to changes in interest rates, which is consistent with binding liquidity constraints.

202. Observing Unobservables: Identifying Information Asymmetries with a Consumer Credit Field Experiment

Abstract:
Information asymmetries are important in theory but difficult to identify in practice. We estimate the presence and importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major South African lender along three dimensions: 1) an initial "offer interest rate" featured on a direct mail solicitation; 2) a "contract interest rate" that was revealed only after a borrower agreed to the initial offer rate; and 3) a dynamic repayment incentive that extended preferential pricing on future loans to borrowers who remained in good standing. These three randomizations, combined with complete knowledge of the Lender's information set, permit identification of specific types of private information problems. Our setup distinguishes adverse selection from moral hazard effects on repayment, and thereby generates unique evidence on the existence and magnitudes of specific credit market frictions. We find evidence of moral hazard and weaker evidence for adverse selection. A rough calibration suggests that perhaps 7% to 16% of default is due to asymmetric information problems. Asymmetric information may help explain the prevalence of credit constraints even in a market that specializes in financing high-risk borrowers at very high rates.

203. Expanding Credit Access: Using Randomized Supply Decisions to Estimate the Impacts

Author:

Abstract:
Expanding credit access is a key ingredient of development strategies worldwide. Microfinance practitioners, policymakers, and donors have ambitious goals for expanding access, and seek efficient methods for implementing and evaluating expansion. There is less consensus on the role of consumer credit in expansion initiatives. Some microfinance institutions are moving beyond entrepreneurial credit and offering consumer loans. But many practitioners and policymakers are skeptical about “unproductive” lending. These concerns are fueled by academic work highlighting behavioral biases that may induce consumers to overborrow. We estimate the impacts of a consumer credit supply expansion using a field experiment and follow-up data collection. A South African lender relaxed its risk assessment criteria by encouraging its loan officers to approve randomly selected marginal rejected applications. We estimate the resulting impacts using new survey data on borrower behavior and well-being, and administrative data on loan repayment. We find that the marginal loans increased credit access and produced measurable benefits in the form of increased employment, reduced hunger, and reduced poverty. The marginal loans also appear to have been profitable for the lender. The results must be interpreted with caution but suggest that consumer credit expansions can be welfare-improving.

204. Teaching Entrepreneurship: Impact of Business Training on Microfinance Clients and Institutions

Author:

Working Paper

Abstract:
Can one teach basic entrepreneurship skills, or are they fixed personal characteristics? Most academic and development policy discussions about microentrepreneurs focus on their access to credit, and assume their human capital to be fixed. The self-employed poor rarely have any formal training in business skills. However, a growing number of microfinance organizations are attempting to build the human capital of micro-entrepreneurs in order to improve the livelihood of their clients and help further their mission of poverty alleviation. Using a randomized control trial, we measure the marginal impact of adding business training to a Peruvian group lending program for female microentrepreneurs. Treatment groups received thirty to sixty minute entrepreneurship training sessions during their normal weekly or monthly banking meeting over a period of one to two years. Control groups remained as they were before, meeting at the same frequency but solely for making loan and savings payments. We find that the treatment led to improved business knowledge, practices and revenues. The program also improved repayment and client retention rates for the microfinance institution. Larger effects found for those that expressed less interest in training in a baseline survey. This has important implications for implementing similar market-based interventions with a goal of recovering costs.

205. Female Empowerment: Impact of a Commitment Savings Product in the Philippines

Abstract:
Female “empowerment” has increasingly become a policy goal, both as an end to itself and as a means to achieving other development goals. Microfinance in particular has often been argued, but not without controversy, to be a tool for empowering women. Here, using a randomized controlled trial, we examine whether access to an individually-held commitment savings product leads to an increase in female decision-making power within the household. We find positive impacts, particularly for women who have below median decision-making power in the baseline, and we find this leads to a shift towards female-oriented durables goods purchased in the household.

206. Why Are There So Few Black-Owned Firms in Africa? Preliminary Results from Enterprise Survey Data

Abstract:
Much of the growth in Sub-Saharan Africa in the past decade has come from extractive industries, rather than from private, entrepreneurial activity. Furthermore, non-extractive activity in the private sector is often dominated by firms owned by ethnic minorities. This paper analyzes the characteristics of the formal private sector in five countries in sub-Saharan Africa, with a particular emphasis on Black African-owned (indigenous) firms. We find that indigenous firms start smaller and grow more slowly; however their rate of growth is positively influenced by whether the owner-entrepreneur has a university degree. We do not find overwhelming evidence that credit is the binding constraint but we do find that indigenous firms get less access to trade credit than firms owned by minority entrepreneurs. Finally, we discuss policy solutions that might enable a larger number of indigenous entrepreneurs to enter and survive in a vibrant, multi-ethnic private sector.

207. How to Do xtabond2: An Introduction to "Difference" and "System" GMM in Stata

Abstract:
The Arellano-Bond (1991) and Arellano-Bover (1995)/Blundell-Bond (1998) linear generalized method of moments (GMM) estimators are increasingly popular. Both are general estimators designed for situations with “small T, large N” panels, meaning few time periods and many individuals; with independent variables that are not strictly exogenous, meaning correlated with past and possibly current realizations of the error; with fixed effects; and with heteroskedasticity and autocorrelation within individuals. This pedagogic paper first introduces linear GMM. Then it shows how limited time span and the potential for fixed effects and endogenous regressors drive the design of the estimators of interest, offering Stata-based examples along the way. Next it shows how to apply these estimators with xtabond2. It also explains how to perform the Arellano-Bond test for autocorrelation in a panel after other Stata commands, using abar.

208. Payments for Progress: A Hands-Off Approach to Foreign Aid

Author:

Working Paper

Center for Global Development
Abstract:
There are significant differences of opinion about the merits of additional aid in meeting the MDGs, including whether and how aid should be given in 'fragile states', whether additional aid on the scale envisioned can be effectively used even in well-managed economies, and whether the aid system, particularly in highly aid-dependent countries, undermines instead of strengthens local institutions. We discuss an approach to scaling up foreign aid that would explicitly be aimed at strengthening local capacity and institutions, including in fragile states. “Payments for progress” would link additional aid to clear evidence of progress already achieved on the ground. This approach would give flexibility and autonomy to local institutions, providing an opening for local institutional experimentation, while at the same time ensuring that aid pays only for real, measurable achievements. Donors would bind themselves as a group to pay a specific amount for clear evidence of progress against one or more agreed goals in low-income developing countries. Developing country governments would present an independently audited statement reporting their progress on the measures, and donors would pay the agreed amount. Payments would be determined as a function of the outcomes, and not linked to the implementation of any particular policies, any other intermediate outputs, or “tied” to purchases from particular suppliers or companies. Governments that found ways to provide services efficiently and so reduce the costs of providing them would benefit from a larger surplus. We discuss the issues such an approach raises—in setting the benchmarks against which progress is measured, in avoiding cheating, and in managing unintended negative consequences of an incentives-based approach. We conclude with a summary of the advantages for donors and recipients.

209. An Index of Donor Performance

Abstract:
The Commitment to Development Index of the Center for Global Development rates 21 rich countries on the “development-friendliness” of their policies. It is revised and updated annually. The component on foreign assistance combines quantitative and qualitative measures of official aid, and of fiscal policies that support private charitable giving. The quantitative measure uses a net transfers concept, as distinct from the net flows concept in the net Official Development Assistance measure of the Development Assistance Committee. The qualitative factors are: a penalty for tying aid; a discounting system that favors aid to poorer, better-governed recipients; and a penalty for “project proliferation.” The charitable giving measure is based on an estimate of the share of observed private giving to developing countries that is attributable to a) lower overall taxes or b) specific tax incentives for giving. De-spite the adjustments, overall results are dominated by differences in quantity of official aid given. This is because while there is a seven-fold range in net concessional transfers/GDP among the scored countries, variation in overall aid quality across donors appears far lower, and private giving is generally small. Denmark, the Netherlands, Norway, and Sweden score highest while the largest donors in absolute terms, the United States and Japan, rank at or near the bottom. Standings by the 2006 methodology have been relatively stable since 1995.

Center for Global Development
Abstract:
IN THIS PAPER, we analyze microfinance institutions (MFIs) as businesses, asking how some MFIs succeed in reducing and covering costs, earning returns, attracting capital, and scaling up. We are interested in MFIs that are financially self-sufficient (covering the cost of daily operations as well as the cost of capital at a commercial rate) or merely operationally self-sufficient (not covering capital costs) or only, say, 90% operationally self-sufficient. All such MFIs strive for efficiency and are in many respects businesslike.
