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.

12. 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.

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

Author:

Publication Date:

Content Type:
Working Paper
Institution:
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.

14. Microfinance as Business

Author:
David Roodman and Uzma Qureshi
Publication Date:

Content Type:
Working Paper
Institution:
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.

15. Artificial States

Center for Global Development
Abstract:
Artificial states are those in which political borders do not coincide with a division of nationalities desired by the people on the ground. We propose and compute for all countries in the world two new measures how artificial states are. One is based on measuring how borders split ethnic groups into two separate adjacent countries. The other one measures how straight land borders are, under the assumption the straight land borders are more likely to be artificial. We then show that these two measures seem to be highly correlated with several measures of political and economic success.

16. Beyond the IMF

Author:

Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
A consensus has developed that the International Monetary Fund (IMF) is not fulfilling its role, prompting multiple proposals for reform. However, this paper argues that the focus on reform should be complemented with an exploration of alternatives outside the IMF which hold the potential to not only give developing countries greater bargaining leverage with the Fund but also, by increasing competition, spurring the institution to better performance. The paper argues that most of the IMF's functions are being carried out in part through alternative institutional arrangements. It focuses in particular on the insurance role of the Fund and argues that developing countries are developing alternative insurance mechanisms, from a higher level of reserves, to regional co-insurance facilities to remittances as a counter-cyclical source of foreign exchange. The de facto exit of its clientele has been driven by the high political costs associated with Fund borrowing and now poses unprecedented challenges for the Fund, in particular pressures on its income. The paper argues for a rapid restructuring and significant cuts of the Fund's administrative budget with the budget savings instead directed to lower the interest rates charged to borrowers.

17. Advance Market Commitments for Vaccines Working Paper and Spread Sheet

Abstract:
The G8 is considering committing to purchase vaccines against diseases concentrated in low-income countries (if and when desirable vaccines are developed) as a way to spur research and development on vaccines for these diseases. Under such an “advance market commitment,” one or more sponsors would commit to a minimum price to be paid per person immunized for an eligible product, up to a certain number of individuals immunized. For additional purchases, the price would eventually drop to close to marginal cost. If no suitable product were developed, no payments would be made. We estimate the offer size which would make revenues similar to the revenues realized from investments in typical existing commercial pharmaceutical products, as well as the degree to which various model contracts and assumptions would affect the cost-effectiveness of such a commitment. We make adjustments for lower marketing costs under an advance market commitment and the risk that a developer may have to share the market with subsequent developers. We also show how this second risk could be reduced, and money saved, by introducing a superiority clause to a commitment. Under conservative assumptions, we document that a commitment comparable in value to sales earned by the average of a sample of recently launched commercial products (adjusted for lower marketing costs) would be a highly cost-effective way to address HIV/AIDS, malaria, and tuberculosis. Sensitivity analyses suggest most characteristics of a hypothetical vaccine would have little effect on the cost-effectiveness, but that the duration of protection conferred by a vaccine strongly affects potential cost-effectiveness. Readers can conduct their own sensitivity analyses employing a web-based spreadsheet tool.

18. A Primer on Foreign Aid

Author:
Steven Radelet
Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
Controversies about aid effectiveness go back decades. Some experts charge that aid has enlarged government bureaucracies, perpetuated bad governments, enriched the elite in poor countries, or just been wasted. Others argue that although aid has sometimes failed, it has supported poverty reduction and growth in some countries and prevented worse performance in others. This new working paper by CGD senior fellow Steve Radelet explores trends in aid, the motivations for aid, its impacts, and debates about reforming aid. It begins by examining aid magnitudes and who gives and receives aid. It discusses the multiple motivations and objectives of aid, some of which conflict with each other. It then explores the empirical evidence on the relationship between aid and growth, which is divided between research that finds no relationship and research that finds a positive relationship (at least under certain circumstances). It also examines some of the key challenges in making aid more effective, including the principal-agent problem and the related issue of conditionality, and concludes by examining some of the main proposals for improving aid effectiveness.

19. Competitive Proliferation of Aid Projects: A Model

Author:
David Roodman
Publication Date:

Working Paper
Institution:
Center for Global Development
Abstract:
The proliferation of aid projects may overburden recipient governments with reporting requirements, donor visits, and other administrative overhead, siphoning off scarce domestic recipient resources, such as tax revenue or the time of skilled government officials, from directly productive use. But greater oversight may also improve the administration of projects, increasing development. I present a model of aid projects that reflects both sides of this coin. It posits a distinction between national-level governance and project-level governance. A donor can raise project-level governance above the baseline national level by requiring oversight activities of the recipient, although the benefits from doing so are less where national-level governance is already high. The model assumes that larger projects demand proportionally less oversight activity from the recipient. Comparative statics analysis suggests that to maximize development, projects should be larger where aid volume is higher, to avoid overburdening recipient administrative capacity; where recipient resources are scarcer, for the same reason; and where national governance is good, since the marginal benefit of oversight is then lower. A multi-donor generalization shows how donors that are imperfectly altruistic, caring most about the success of their own projects, will tend to sink into competitive proliferation, in which each donor subdivides its aid budget into smaller projects to raise the marginal productivity of the recipient's resources in those projects and attract them away from other donors. The inefficiency arises from the lack of a market among donors for recipient resources. In a Nash equilibrium, competitive proliferation reduces overall development. But the smallest (selfish) donors can gain. This would discourage them from cooperating with other donors to contain competitive proliferation.

20. Privatization: A Summary Assessment

Author:

Publication Date:

Working Paper
Institution:
Center for Global Development
Abstract:
In the last 25 years many thousands of formerly state-owned and operated firms have been privatized in developing and transition countries, generating over $400 billion (US) in sales proceeds. In addition, thousands of firms have been transferred by privatization processes in which no money was raised (though a surprising number of state-owned firms remain in these regions). The vast majority of economic studies praise privatization's positive impact at the level of the firm, as well as its positive macroeconomic and welfare contributions. Moreover, contrary to popular conception, privatization has not contributed to maldistribution of income or increased poverty——at least in the best-studied Latin American cases. In sum, the technical picture is generally positive. Nonetheless, public opinion in the less developed world is generally suspicious of, and often hostile to, privatization. A good part of the problem is that privatization has proven harder to launch, and is more likely to produce errant results, in low-income, institutionally weak states, particularly in the most important infrastructure sectors. Privatization is hard to sell politically; it has become a lightning rod and handy scapegoat for all discontent related to liberalization and globalization. What is needed are reform mechanisms that give incentives and comfort to reputable private investors, that create and sustain the policy and regulatory institutions that make governments competent and honest partners with the private operators, while at the same time protecting consumers, particularly the most disadvantaged, from abuse.
