Abstract:
This paper addresses the question of investment in sub-Saharan African listed securities by examining characteristics of the continent's 15 equity markets, the rise and fall of African regional funds, and the asset allocation trends for global emerging market (GEM) funds. The data shows that South Africa is now a leading destination of capital, but that few managers invest elsewhere on the continent. However, we find that African markets are not treated differently than other markets and present evidence that small market size and low levels of liquidity are a binding deterrent for foreign institutional investors. Thus, orthodox market variables rather than market failure appear to explain Africa's low absolute levels of inward equity flows. The paper then turns to new data from firm surveys to explore why African firms remain small. The implications of our findings are threefold: (a) efforts to encourage greater private investment in these markets should concentrate on domestic audiences and specialized regional funds, (b) the depth and success of the Johannesburg Stock Exchange can perhaps be better utilized to benefit other parts of the continent, and (c) any long-term strategy should concentrate on the underlying barriers to firm entry and growth.

2. 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.

3. 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.

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

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.
