Abstract:
We examine the growth of mobile phone technology over the past decade and consider its potential impacts upon quality of life in low-income countries, with a particular focus on sub-Saharan Africa. We first provide an overview of the patterns and determinants of mobile phone coverage in sub-Saharan Africa before describing the characteristics of primary and secondary mobile phone adopters on the continent. We then discuss the channels through which mobile phone technology can impact development outcomes, both as a positive externality of the communication sector and as part of mobile phone-based development projects, and analyze existing evidence. While current research suggests that mobile phone coverage and adoption have had positive impacts on agricultural and labor market efficiency and welfare in certain countries, empirical evidence is still somewhat limited. In addition, mobile phone technology cannot serve as the “silver bullet” for development in sub-Saharan Africa. Careful impact evaluations of mobile phone development projects are required to better understand their impacts upon economic and social outcomes, and mobile phone technology must work in partnership with other public good provision and investment.

112. The Roots of Global Wage Gaps: Evidence from Randomized Processing of U.S. Visas

Abstract:
This study uses a unique natural experiment to test a simple model of international differences in workers' wages and productivity. Large differences in wages across countries could arise from several sources. These include barriers to trade in outputs, differences in technology, differences in workers, or differences in the other factors of production accessible in different countries. To measure the relative importance of these sources in one setting, this study exploits the randomized processing of U.S. visas for a group of Indian workers who produce software within a single multinational firm. In this setting, international barriers to trade in outputs, barriers to technology transfer, and all observable or unobservable differences between workers are extremely low. The results indicate that location outside of India causes a sixfold increase in the wages of the same worker using the same technology to produce a highly tradable good. Under plausible assumptions about competition in the industry, this suggests that country-of-work by itself is responsible—in this industry—for roughly three-quarters of the gap in productivity between workers in India and workers in the richest countries. These findings have implications for open questions in labor, growth, international, and development economics.

113. Inside the World Bank's Black Box Allocation System: How Well Does IDA Allocate Resources to the Neediest and Most Vulnerable Countries?

Abstract:
During the last few International Development Association (IDA) replenishment negotiations, several large donors have pressed for reforms to further increase the share of IDA resources provided to the neediest and most vulnerable countries. While the proposed reforms take different forms, the philosophical Thrust is the same—push IDA's focus further down the development chain. Against this backdrop, this paper explores just how well IDA's existing performance-based allocation (PBA) system actually addresses these issues. To achieve this, I examine how IDA allocations are distributed at each successive stage of the PBA methodology based upon a number of need and vulnerability measures. Next, I apply two simple measures to gauge IDA's performance: (1) whether per-capita allocations to the neediest and most vulnerable countries are equal to or greater than those for the best off countries and (2) whether allocations to the neediest and most vulnerable countries increase between the baseline and final allocation scenarios. Based on these criteria, IDA has a mixed track record. IDA's performance is very modest with respect to the relative share allocated to the neediest or most vulnerable countries. Of the eight measures examined, only two illustrate parity between final allocations to the bottom and top quartile of countries. However, the litany of PBA exceptions clearly helps to redistribute resources in absolute terms. Per-capita allocations to the neediest and most vulnerable countries more than doubles between the baseline and final PBA scenarios for every need and vulnerability indicator examined. Clearly, the existing system has several built-in biases to redistribute resources to these countries. However, these exceptions fall short from ensuring full parity that some IDA donors may wish to achieve. As such, the philosophical debate among key IDA donors likely will continue for the foreseeable future.

114. Beyond Population: Everyone Counts in Development

Author:
Joel E. Cohen
Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development (CGD)
Abstract:
This essay reviews some of the most important demographic trends expected to occur between 2010 and 2050, indicates some of their implications for economic and global development, and suggests some possible policies to respond these trends and implications. The interactions of population, economics, the environment, and culture are central. In the past decade, for the first time in history, old people outnumbered young people, urban people outnumbered rural people, and women of reduced fertility outnumbered women of high fertility. The century from 1950 to 2050 will have included the highest global population growth rate ever, the largest voluntary fall in the global population growth rate ever, and the most enormous shift ever in the demographic balance between the more developed regions of the world and the less developed ones. In the coming half century, according to most demographers, the world's population will grow older, larger (albeit more slowly), and more urban than in the 20th century, but with much variance within and across regions. No one knows what numbers and demographic characteristics of humans are sustainable, but it is clear that the prodigious stain of a billion or so chronically hungry people at present results from recent and ongoing collective human choices, not biophysical necessities. Concrete policy options to respond to demographic trends include providing universal primary and secondary education, particularly education for global and household civility; eliminating unmet needs for contraception and reproductive health; and implementing demographically sensitive urban planning, particularly construction for greater energy efficiency and friendliness to older people.

115. Can Donors Be Flexible within Restrictive Budget Systems? Options for Innovative Financing Mechanisms

Author:
Benjamin Leo
Publication Date:

Content Type:
Working Paper
Institution:
Center for Global Development (CGD)
Abstract:
This paper focuses on how budgetary scorekeeping systems affect governments' ability or willingness to support innovative development finance initiatives and explores several options to overcome the restrictions the systems often impose. As a starting point, it assumes that donor governments, such as the United States, will not reform their budgetary system regulations to accommodate innovative development finance commitments due to political and budget policy concerns. In general, each option outlined entails important financial, political, and bureaucratic challenges and tradeoffs. In other words, there are no silver bullets. However, there are possible approaches that may merit further exploration by donor governments that want to support specific innovative development finance initiatives but are constrained by existing budgetary systems.

116. When Does Rigorous Impact Evaluation Make a Difference? The Case of the Millennium Villages

Abstract:
When is the rigorous impact evaluation of development projects a luxury, and when a necessity? We study one high-profile case: the Millennium Villages Project (MVP), an experimental and intensive package intervention to spark sustained local economic development in rural Africa. We illustrate the benefits of rigorous impact evaluation in this setting by showing that estimates of the project's effects depend heavily on the evaluation method. Comparing trends at the MVP intervention sites in Kenya, Ghana, and Nigeria to trends in the surrounding areas yields much more modest estimates of the project's effects than the before-versus-after comparisons published thus far by the MVP. Neither approach constitutes a rigorous impact evaluation of the MVP, which is impossible to perform due to weaknesses in the evaluation design of the project's initial phase. These weaknesses include the subjective choice of intervention sites, the subjective choice of comparison sites, the lack of baseline data on comparison sites, the small sample size, and the short time horizon. We describe how the next wave of the intervention could be designed to allow proper evaluation of the MVP's impact at little additional cost.

117. Austerity and the IMF

Abstract:
It is a great honor to present the fifth annual Richard H. Sabot lecture at the Center for Global Development. In this talk, I will take up a relatively narrow but absolutely fundamental question in the international monetary system, particularly in developing countries: Is the International Monetary fund (the IMF) guilty of bringing excessive austerity to the countries that turn to it for bailout funding? Should the IMF instead put much more weight on encouraging countercyclical fiscal policy, as it does in rich countries? Extremely difficult and complex issues underlie these seemingly straightforward questions. My modest aim in this lecture is to help clarify the issues so as to promote rational dialogue.

118. Aid for Trade: Supporting Trade Preference Reform

Abstract:
Aid-for-trade programs can help strengthen low-income countries' supply capacity and knowledge of trade preferences, which will allow them to take fuller advantage of these preferences. Aid for trade to support preference reform can be divided into three categories: (i) creation of information-sharing mechanisms to ensure that governments, SMEs and other businesses are aware of the opportunities that preferential market access offers; (ii) capacity-building support to overcome supply-side and policy constraints; and (iii) support to ease the adjustments to preference erosion that will inevitably occur. As with other aid initiatives, coordination and cohesion among assistance programs is critical for success. Delivery mechanisms such as the Enhanced Integrated Framework (EIF), the Trade Facilitation Facility (TFF), and the Standards and Trade Development Facility (STDF), are aimed at facilitating such coordination, but more could be done. And, as preference programs are intended to be temporary, aid for trade can also facilitate graduation from these programs and compensate beneficiaries for preference erosion. Unfortunately, this area is still lacking the level of innovation and financial support needed.

Abstract:
International Development Association (IDA) donors and others operating a country performance-based allocation system face two difficult problems: how to strengthen incentives to produce and document development results and how to increase flexibility for fragile states. Fragile states have the greatest need for projects, but their projects tend to rate poorly in performance-based allocations systems, which provide little incentive to produce successful projects in fragile states or other countries.

Working Paper
Institution:
Center for Global Development (CGD)
Abstract:
The Jubilee 2000 movement, which called for the cancellation of the foreign debts of the poorest nations, reached its zenith in the late 1990s and 2000-and then, by design, shut down. In the space of a few years, it became one of the most successful international, nongovernmental movements in history. As part of a larger, ongoing project to understand the consequences and lessons of the episode, David Roodman provides thumbnail assessments of Jubilee 2000 from several perspectives, deemphasizing anecdotes and statistics in favor of major themes.
