This paper examines whether, in the presence of trade preferences, Sub-Saharan African economies, and especially its poorest households, could gain from multilateral trade reform. The World Bank’s LINKAGE model of the global economy is employed to examine the impact first of current trade...

The design of cost minimizing procurement rules for the selection of contractors among distinct technological groups requires the favouritism of inefficient firms. It is unclear whether these policies provide incentives for inefficient firms to adopt more efficient technologies. In this paper...

We construct and estimate a unified model combining three of the main sources of cross-country income disparities: differences in factor endowments, barriers to technology adoption and the inappropriateness of frontier technologies to local conditions. The key components are different types of...

A common-agency lobbying model is developed to help understand why North America and the European Union have adopted such different policies towards genetically modified food. Our results show that when firms (in this case farmers) lobby policy-makers to influence standards and consumers and...

To what extent has Sub-Saharan Africa’s slow economic growth over the past five decades been due to price and trade policies that have discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy distortions to relative prices...

Africa’s recent growth performance has raised expectations of a bright economic future for the continent after decades of decline. Yet there is a genuine question about whether Africa’s growth can be sustained, and if so, at what level. The balance of the evidence suggests caution on the...

In their survey of the literature on ethnic fractionalization and economic performance, Alesina and La Ferrara (JEL 2005) identify two main directions for future research. One is to improve the measurement of diversity and the other to treat diversity as an endogenous variable. This paper tries...

Does fractionalization change over (short periods of) time? If so, are there any substantial implications for economic performance? To answer such questions, we construct a new panel data set with measures of fractionalization for 26 former communist countries covering the period from 1989 to...

Many countries have failed to use natural resource wealth to promote growth and development. They have been damaged by volatility of revenues, have failed to save a sufficiently high proportion of their resource revenues and failed to make high return investments to support diversification of...

Cross-country evidence is presented on resource dependence and the link between volatility and growth. First, growth depends negatively on volatility of unanticipated output growth independent of initial income per capita, the average investment share, initial human capital, trade openness, the...
