191. Reviving Economic Growth in Liberia

Author:

Content Type:

Abstract:
Liberia was decimated by 25 years of gross economic mismanagement and 14 years of brutal civil war. GDP fell by over 90% in less than two decades, one of the largest economic collapses in the world since World War II. This paper explores the challenges in reinvigorating rapid, inclusive, and sustained economic growth in the post-war environment. It stresses the importance of not just reigniting growth, but rebuilding the economy in a way that avoids the substantial income concentration of the past and creates significant economic opportunities to groups that were marginalized and excluded in the past. It examines the new government's progress so far, including the major steps it has taken in its first 18 months and the unique way that it has organized government-donor relations.

192. A Short Note on the Theme of Too Many Instruments

Author:

Working Paper

Center for Global Development
Abstract:
The “difference” and “system” generalized method of moments (GMM) estimators for dynamic panel models are growing steadily in popularity. The estimators are designed for panels with short time dimensions (T), and by default they generate instruments sets whose number grows quadratically in T. The dangers associated with having many instruments relative to observations are documented in the applied literature. The instruments can overfit endogenous variables, failing to expunge their endogenous components and biasing coefficient estimates. Mean while they can vitiate the Hansen J test for joint validity of those instruments, as well as the difference-in-Sargan/Hansen test for subsets of instruments. The weakness of these specification tests is a particular concern for system GMM, whose distinctive instruments are only valid under a non-trivial assumption. Judging by current practice, many researchers do not fully appreciate that popular implementations of these estimators can by default generate results that simultaneously are invalid yet appear valid. The potential for type I errors—false positives—is therefore substantial, especially after amplification by publication bias. This paper explains the risks and illustrates them with reference to two early applications of the estimators to economic growth, Forbes (2000) on income inequality and Levine, Loayza, and Beck (LLB, 2000) on financial sector development. Endogenous causation proves hard to rule out in both papers. Going forward, for results from these GMM estimators to be credible, researchers must report the instrument count and aggressively test estimates and specification test results for robustness to reductions in that count.

193. Pathways Out of Poverty During an Economic Crisis: An Empirical Assessment of Rural Indonesia

Author:

Working Paper

Abstract:
Most poor people in developing countries still live in rural areas and are primarily engaged in low productivity farming activities. Thus pathways out of poverty are likely to be strongly connected to productivity increases in the rural economy, whether they are realised in farming, rural non-farm enterprises or via rural-urban migration. We use cross-sectional data from the Central Statistical Board (BPS) for 1993 and 2002, as well as a panel data set from the Indonesia Family Life Survey (IFLS) for 1993 and 2000, to show which pathways out of poverty were most successful over this period. Our findings suggest that increased engagement of farmers in rural non-farm enterprises is an important route out of rural poverty, but that most of the rural agricultural poor that exit poverty still do so while remaining rural and agricultural. Thus changes in agricultural prices, wages and productivity still play a critical role in moving people out of poverty.

194. What Have IMF Programs With Low-Income Countries Assumed About Aid Flows?

Author:
David Goldsbrough and Ben Elberger
Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
This paper examines the nature of aid projections in IMF programs with low-income countries. On average, IMF projections of net aid increased sharply in the first year of programs but tapered off in subsequent years. Projections were also significantly more optimistic in countries with low initial levels of aid but differed little across regions. Most notably, projections of net aid to countries in Sub-Saharan Africa following the Gleneagles Summit are significantly more pessimistic than the path implied by commitments to double aid to Africa by 2010. This pattern is strong throughout the group with only two Sub-Saharan African countries showing increases in net aid consistent with the Gleneagles commitments.

195. Income Distribution: Effects on Growth and Development

Author:
Nancy Birdsall
Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
I review the literature on the effects of inequality on growth and development in the developing world. Two stylized facts emerge from empirical studies: inequality is more likely to harm growth in countries at low levels of income (below about $3200 per capita in 2000 dollars); and it is at high levels of inequality (at or above a Gini coefficient of .45) that a negative association emerges. Between 15 and 40 percent of the developing world's population lives in countries with these characteristics, depending on the inclusion of China, whose level of inequality has recently been measured at almost .45. Theory and evidence suggest that high inequality affects growth: (1) through interaction with incomplete and underdeveloped markets for capital and information; (2) by discouraging the evolution of the economic and political institutions associated with accountable government (which in turn enable a market environment conducive to investment and growth); and (3) by undermining the civic and social life that sustains effective collective decision-making.

196. Performance-based Incentives for Health: Demand- and Supply-Side Incentives in the Nicaraguan Red de Protección Social

Author:

Publication Date:

Working Paper

Center for Global Development
Abstract:
Nicaragua's Red de Protección Social (RPS) is one of the first conditional cash transfer (CCT) programs implemented in a low-income country. Demand-side incentives, in the form of monetary transfers, are provided to poor households on condition that their children attend school and visit preventive health care providers. The design of the program is unique among CCT programs because these demand-side incentives are complemented by supply-side incentives aimed at improving the provision of health care. Health care providers are paid on the basis of their performance against predetermined targets. Both private and nonprofit health care providers contracted by the government extend the coverage of services to previously underserved areas.

197. Performance-Based Incentives for Health: Conditional Cash Transfer Programs in Latin America and the Caribbean

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
In order to support poor families in the developing world to seek and use health care, a multi-pronged strategy is needed on both the supply and the demand side of health care. A demand-side program called Conditional Cash Transfers (CCTs) strives to reduce poverty and also increase food consumption, school attendance, and use of preventive health care. Since 1997, seven countries in Latin America have implemented and evaluated CCT programs with health and nutrition components. The core of the program is based on encouraging poor mothers to seek preventive health services and attend health education talks by providing a cash incentive for their healthy behavior (with healthy behavior representing performance). Evaluations of these programs measured outputs in the utilization of services; health knowledge, attitudes, and practice; food consumption; the supply and quality of services; as well as outcomes in vaccination rates; nutritional status; morbidity; mortality; and fertility.

198. Performance-Based Incentives for Health: Six Years of Results from Supply-Side Programs in Haiti

Abstract:
USAID launched a project in 1995 to deliver basic health services in Haiti. The project began by reimbursing contracted NGOs for documented expenditures or inputs. In 1999, payment was changed to being based partly on attaining performance targets or outputs. The project also provided technical assistance to the NGOs, along with opportunities to participate in an NGO network and other cross-fertilization activities. Remarkable improvements in key health indicators have been achieved in the six years since payment for performance was phased in. Although it is difficult to isolate the effects of performance-based payment on these improved indicators from the efforts aimed at strengthening NGOs and other factors, panel regression results suggest that the new payment incentives were responsible for considerable improvements in both immunization coverage and attended deliveries. Results for prenatal and postnatal care were less significant, perhaps suggesting a strong patient behavioral element that is not under the influence of provider actions.

199. Performance-Based Incentives for Health: A Way to Improve Tuberculosis Detection and Treatment Completion?

Author:
Rena Eichler, Diana Weil, and Alexandra Beith
Publication Date:

Abstract:
Tuberculosis is a public health emergency in Africa, Eastern Europe, and Central Asia. Of the estimated 1.7 million deaths from TB, 98 percent are in the developing world, the majority being among the poor. In order to reach the MDG and the Stop TB partnership targets for 2015, TB detection rates need to double, treatment success rates must increase to more than 7075 percent, and strategies to address HIV-associated TB and multi-drug resistant TB must be aggressively expanded. DOTS, the internationally-recommended TB control strategy is the foundation of TB control efforts worldwide. A standard recording and monitoring system built on routine service-based data allows nearly all countries in the world to track progress in case detection and treatment completion through routine monitoring. This provides a good base for measuring the impact of different strategies for improving TB control outcomes.

200. Do No Harm: Aid, Weak Institutions, and the Missing Middle in Africa

Author:
Nancy Birdsall
Publication Date:
03-2007
Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
The implicit assumption of the donor community is that Africa is trapped by its poverty, and that aid is necessary if Africa is to escape the trap. In this note I suggest an alternative assumption: that Africa is caught in an institutional trap, signaled and reinforced by the small share of income of its independent middle-income population. Theory and historical experience elsewhere suggest that a robust middle-income group contributes critically to the creation and sustenance of healthy institutions, particularly healthy institutions of the state. I propose that if external aid is to be helpful for institution-building in Africa's weak and fragile states, donors need to emphasize not providing more aid but minimizing the risks more aid poses for this group in Africa.
