161. Blunt Instruments: On Establishing the Causes of Economic Growth

Author:

Content Type:
Working Paper

Center for Global Development
Abstract:
Despite intense concern that many instrumental variables used in growth regressions may be weak, invalid, or both, top journals continue to publish studies of economic growth based on problematic instruments. Doing so risks pushing the entire literature closer to irrelevance. We illustrate hidden problems with identification in recent prominently published and widely cited growth studies using their original data. We urge researchers to take three steps to overcome the shortcomings: grounding research in somewhat more generalized theoretical models, deploying the latest methods to test sensitivity to violations of the exclusion restriction, and opening the “black box” of the Generalized Method of Moments (GMM) with supportive evidence of instrument strength.

162. The Impact of Microcredit on the Poor in Bangladesh: Revisiting the Evidence

Author:
David Roodman and Jonathan Morduch

Working Paper
Institution:
Center for Global Development
Abstract:
The most-noted studies on the impact of microcredit on households are based on a survey fielded in Bangladesh in the 1990s. Contradictions among them have produced lasting controversy and confusion. Pitt and Khandker (PK, 1998) apply a quasi-experimental design to 1991–92 data; they conclude that microcredit raises household consumption, especially when lent to women. Khandker (2005) applies panel methods using a 1999 resurvey; he concurs and extrapolates to conclude that microcredit helps the extremely poor even more than the moderately poor. But using simpler estimators than PK, Morduch (1999) finds no impact on the level of consumption in the 1991–92 data, even as he questions PK's identifying assumptions. He does find evidence that microcredit reduces consumption volatility. Partly because of the sophistication of PK's Maximum Likelihood estimator, the conflicting results were never directly confronted and reconciled. We end the impasse. A replication exercise shows that all these studies' evidence for impact is weak. As for PK's headline results, we obtain opposite signs. But we do not conclude that lending to women does harm. Rather, all three studies appear to fail in expunging endogeneity. We conclude that for non-experimental methods to retain a place in the program evaluator's portfolio, the quality of the claimed natural experiments must be high and demonstrated.

164. Pricing and Access: Lessons from Randomized Evaluations in Education and Health

Author:
Michael Kremer and Alaka Holla
Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
This paper surveys evidence from recent randomized evaluations in developing countries on the impact of price on access to health and education. The debate on user fees has been contentious, but until recently much of the evidence was anecdotal. Randomized evaluations across a variety of settings suggest prices have a large impact on take-up of education and health products and services. While the sign of this effect is consistent with standard theories of human capital investment, a more detailed examination of the data suggests that it may be important to go beyond these models. There is some evidence for peer effects, which implies that for some goods the aggregate response to price will exceed the individual response. Time-inconsistent preferences could potentially help explain the apparently disproportionate effect of small short-run costs and benefits on decisions with long-run consequences.

165. Do Regulatory Reforms Stimulate Investment and Growth? Evidence from the Doing Business Data

Author:

Working Paper
Institution:
Center for Global Development
Abstract:
The role of regulatory barriers in inhibiting entrepreneurship, investment and employment creation is an old topic in economics. This study utilizes a five-year panel of data on regulations and procedures from the World Bank's Doing Business project, along with Arellano-Bond dynamic panel estimators, looking for evidence that regulatory reforms lead to higher aggregate investment rates (roughly, factor demand) or GDP growth conditional on investment rates (roughly, factor productivity). It looks both at individual regulatory indicators and more aggregate measures of the incidence of reforms, finding some evidence of positive impacts of regulatory reforms in countries which are relatively poor (conditional on governance) and relatively well-governed (conditional on income). Relatively poor and relatively well-governed countries grow about 0.4 and 0.2 percentage points faster in the year immediately following one or more reforms, respectively. In both subsets of countries, investment rates accelerate by about 0.6 percentage points in the subsequent year.

166. Criss-Crossing Globalization: Uphill Flows of Skill-Intensive Goods and Foreign Direct Investment

Author:
Arvind Subramanian and Aaditya Mattoo
Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
This paper documents an unusual and possibly significant phenomenon: the export of skills, embodied in goods, services or capital from poorer to richer countries. We first present a set of stylized facts. Using a measure which combines the sophistication of a country's exports with the average income level of destination countries, we show that the performance of a number of developing countries, notably China, Mexico and South Africa, matches that of much more advanced countries, such as Japan, Spain and USA. Creating a new combined dataset on FDI (covering greenfield investment as well as mergers and acquisitions) we show that flows of FDI to OECD countries from developing countries like Brazil, India, Malaysia and South Africa as a share of their GDP, are as large as flows from countries like Japan, Korea and the US. Then, taking the work of Hausmann et al (2007) as a point of departure, we suggest that it is not just the composition of exports but their destination that matters. In both cross-sectional and panel regressions, with a range of controls, we find that a measure of uphill flows of sophisticated goods is significantly associated with better growth performance. These results suggest the need for a deeper analysis of whether development benefits might derive not from deifying comparative advantage but from defying it.

167. Climate Change Negotiating Positions of Major Developing Country Emitters

Author:

Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
Developing countries with large greenhouse gas emissions play a decisive role in negotiating a post-Kyoto climate agreement. No effective program to reduce global emissions is possible without their support. At the same time, developing countries face a delicate task in balancing their growing responsibility for a livable climate with the pursuit of continued economic development. This article discusses the negotiating positions major developing country emitters are taking on core issues. Among the most vital unsettled questions are burden sharing between developed and developing countries, the role of the market in the international climate architecture, as well as implementation arrangements. An annex discusses current mitigation policies of major developing country emitters, and argues that developing countries are already taking meaningful action to limit the growth of their greenhouse gas emissions.

168. Beyond Planning: Markets and Networks for Better Aid

Author:
Owen Barder
Publication Date:
10-2009
Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
The political economy of aid agencies is driven by incomplete information and multiple competing objectives and confounded by principal-agent and collective-action problems. Policies to improve aid rely too much on a planning paradigm that tries to ignore, rather than change, the political economy of aid. A considered combination of market mechanisms, networked collaboration, and collective regulation would be more likely to lead to significant improvements. A “collaborative market” for aid might include unbundling funding from aid management to create more explicit markets; better information gathered from the intended beneficiaries of aid; decentralized decision-making; a sharp increase in transparency and accountability of donor agencies; the publication of more information about results; pricing externalities; and new regulatory arrangements to make markets work. The aid system is in a political equilibrium, determined by deep characteristics of the aid relationship and the political economy of aid institutions. Reformers should seek to change that equilibrium rather than try to move away from it. The priority should be on reforms that put pressure on the aid system to evolve in the right direction rather than on grand designs.

169. Countering Drug Resistance in the Developing World: An Assessment of Incentives across the Value Chain and Recommendations for Policy Interventions

Abstract:
The emergence and spread of drug resistance is draining available resources and threatening our ability to treat infectious diseases in developing countries. Countering drug resistance requires pharmaceutical companies, government regulators, doctors, and patients to make difficult choices about drug treatment in order to balance efficacy, cost, safety, and sustainability of drugs. These complex tradeoffs are faced along the drug supply chain from the development of new products, procurement of drugs for donor and government distribution, distribution steps to ensure treatment heterogeneity along with quality and availability, and dispensing and use that requires affordability, patient adherence and rational use of drugs and diagnostics. An analysis of the incentives and risks in the drug supply chain reflects that many stakeholders who can influence optimal prescribing of existing drugs; affect higher patient compliance; and ensure the quality of drugs have weak incentives to carry out these activities optimally. This implies a high potential for drug resistance to accelerate. This paper recommends specific measures to better align the incentives of these stakeholders with resistance- countering activities.

170. Climate Change and the Future Impacts of Storm-Surge Disasters in Developing Countries

Abstract:
As the climate changes during the 21st century, larger cyclonic storm surges and growing populations may collide in disasters of unprecedented size. As conditions worsen, variations in coastal morphology will magnify the effects in some areas, while largely insulating others. In this paper, we explore the implications for 84 developing countries and 577 of their cyclone-vulnerable coastal cities with populations greater than 100,000. Combining the most recent scientific and demographic information, we estimate the future impact of climate change on storm surges that will strike coastal populations, economies and ecosystems. We focus on the distribution of heightened impacts, because we believe that greater knowledge of their probable variation will be useful for local and national planners, as well as international donors. Our results suggest gross inequality in the heightened impact of future disasters, with the most severe effects limited to a small number of countries and a small cluster of large cities.
