Carsten Fink, Aaditya Mattoo World Bank Policy Research Working Papers. 2002.  No. 2852.
Every major regional trade agreement now has a services dimension. Is trade in services so different that there is need to modify the conclusions on preferential agreements pertaining to goods reached so far? Mattoo and Fink first examine the implications of unilateral policy choices in a particular services market. They then explore the economics of international cooperation and identify the circumstances in which a country is more likely to benefit from cooperation in a regional rather than multilateral forum.

L. Alan Winters, Maurice Schiff World Bank Policy Research Working Papers. 2002.  No. 2872.
Schiff and Winters examine regional cooperation among neighboring countries in the area of regional public goods. These public goods include water basins (such as lakes, rivers, and underground water), infrastructure (such as roads, railways, and dams), energy, and the environment. Their analysis focuses on developing countries and the potentially beneficial role that international organizations and regional integration may play in bringing the relevant countries to a cooperative equilibrium. A major problem in reaching a cooperative solution is likely to be the lack of trust. If neighboring countries do not trust each other because of past problems, they may fail to reach a cooperative solution as each tries to maximize its gain from the regional public good. These strategies typically do not account for spillover effects and ultimately leads to losses for all parties. Other constraints on reaching a cooperative solution are its complexity and the financial requirements. Two types of institutions may help resolve some or all of these problems. International organizations can help with trust, expertise, and financing. The United Nations and the World Bank have been involved in a number of such projects in Africa, Asia, and elsewhere, and have been successful in helping parties reach cooperative solutions. Regional integration agreements, though not necessary for regional cooperation, may also be helpful by embedding the negotiations on regional cooperation in a broader institutional framework. The authors examine these issues with the support of both analysis and a number of case studies.

Yanling Wang, Maurice Schiff World Bank Policy Research Working Papers. 2003.  No. 3132.
The literature on regional integration agreements (RIAs) is vast and deals with political, economic, and political economy issues. The literature on the economics of RIAs deals mostly with static effects, and concludes that these effects are, in general, ambiguous. So far there has been no empirical analysis of the dynamic effects of RIAs based on their impact on technology diffusion from partner and nonpartner countries. Schiff and Wang's paper is a first attempt in this direction. The authors examine the impact of the North America Free Trade Agreement (NAFTA) on total factor productivity in Mexico through its impact on trade-related technology transfers from OECD countries. They estimate trade-related technology diffusion by using a measure of trade-related foreign research and development (R&D). Foreign R&D is constructed based on industry-specific R&D in the OECD, OECD-Mexico trade patterns, and input-output relations in Mexico. The authors find that: (i) Mexico’s trade with its NAFTA partners had a large and significant impact on Mexico’s total factor productivity, while trade with the rest of the OECD did not. (ii) Simulating the impact of NAFTA has led to a permanent increase in total factor productivity in Mexico’s manufacturing sector of between 5.5 percent and 7.5 percent and to some convergence with the economies of Canada and the United States.

George Psacharopoulos, Harry Anthony Patrinos World Bank Policy Research Working Papers. 2002.  No. 2881.
Returns to investment in education based on human capital theory have been estimated since the late 1950s. In the 40-plus year history of estimates of returns to investment in education, there have been several reviews of the empirical results in attempts to establish patterns. Many more estimates from a wide variety of countries, including over time evidence, and estimates based on new econometric techniques, reaffirm the importance of human capital theory. This paper reviews and presents the latest estimates and patterns as found in the literature at the turn of the century. However, because the availability of rate of return estimates has grown exponentially, we include a new section on the need for selectivity in comparing returns to investment in education and establishing related patterns.

Julio J. Nogués World Bank Policy Research Working Papers. 2003.  No. 3088.
On December 10, 2001 the U.S. Department of Commerce (DOC) imposed steep antidumping duties against honey imports from Argentina and China ranging from 32.6 percent to 183.8 percent, and a countervailing duty against Argentina of 5.9 percent. A previous antidumping investigation in 1995 ended with a suspension “agreement” that curtailed U.S. imports from China by around 30 percent. Millions of beekeepers around the world, most of them poor, make a living from honey production, and a free and competitive world market would help raise their standards of living. Nevertheless, the sequential pattern of increasing and widening protectionism followed by the United States, the world’s top importer, to include successful exporters under the effects of its contingent protection measures sends a clear message that other countries should think twice before investing in expanding honey exports to the United States. In addition to looking into the trade effects of these contingent protection measures, Nogués concludes that under the regulatory arrangements of the DOC, Argentina’s beekeepers never had a chance of defending themselves. For example, responding to the DOC’s lengthy and sophisticated questionnaires that sought to determine cost of production went beyond the capacities of poor beekeepers. In the absence of information, the DOC resorted to evidence presented by the petitioners which was riddled with errors. The available evidence suggests that had beekeepers been capable of responding to the questionnaires, the margin of dumping would had been lower, if at all existent. This and other evidence discussed by Nogués suggest the urgent need to introduce reforms into the World Trade Organization antidumping and subsidy agreements. At the minimum what is required is a consensus that all respondents be given the same opportunity by the international trade rules. The author argues that at present this is not the case and offers suggestions for reforms.

Ayesha Yaqub Vawda, Varun Gauri World Bank Policy Research Working Papers. 2003.  No. 3005.
Voucher programs consist of three simultaneous reforms: allowing parents to choose schools, creating intense incentives for schools to increase enrollment, and granting schools management autonomy to respond to demand. As a result, voucher advocates and critics tend to talk past each other. A principal-agent framework clarifies the argument for education vouchers. Central findings from the literature, including issues related to variance in the performance measure, risk aversion, the productivity of more effort, multiple tasks, and the value of monitoring are found relevant for an analysis of vouchers. An assessment of findings on voucher programs in industrial countries, as well as a review of voucher or quasi-voucher experiences in Bangladesh, Chile, Colombia, Côte d’Ivoire, and the Czech Republic support the usefulness of the analytic framework. Gauri and Vawda conclude that vouchers for basic education in developing countries can enhance outcomes when they are limited to modest numbers of poor students in urban settings, particularly in conjunction with existing private schools with surplus capacity. The success of more ambitious voucher programs depends on an institutional infrastructure challenging to industrial and developing countries alike. This paper—a joint product of Public Services, Development Research Group, and the Education Team, Human Development Network—is a background paper for the 2004 World Development Report.
