Calculations of marginal welfare effects suggest that agricultural development has had important positive effects on national welfare, especially in developing countries. Latin American and Caribbean countries have also benefited from agricultural growth, but non-agricultural production has had...

Lederman and Maloney trace the evolution of research and development (R&D) expenditures along the development process using a new global panel data set. They show that R&D effort measured as a share of GDP rises with development at an increasing rate. The authors examine how four groups of...

The United States imports around 25 percent of its merchandise under some form of preferential trade regime. The authors examine both the origins and consequences of U.S. trade preferences in the context of the gravity model of international trade. First, they provide estimates of the impact of...

Lederman and Maloney examine the empirical relationships between trade structure and economic growth, particularly the influence of natural resource abundance, export concentration, and intra-industry trade. They test the robustness of these relationships across proxies, control variables, and...

The authors rely on a series of growth accounting exercises to determine whether the growth rate of total factor productivity (TFP) or the unexplained portion of GDP growth (after controlling for the accumulation of capital per worker) in 18 Latin American and Caribbean economies has benefited...

The authors use disaggregated export data to explore the relationship between economic discovery and economic development. They find that discoveries, or episodes, when countries begin exporting a new product are not limited to so-called"dynamic"industries. Rather, they also occur in traditional...

The authors have prepared this paper as a companion to the Trade and Production database, which contains trade, production, and tariff data for 67 industrial and developing countries at the industry level for 1976-99. The sector disaggregation in the database follows the International Standard...

The European Union (EU), Japan, and the United States (US) have recently announced initiatives to improve market access for the poorest countries. The authors assess the impact on Sub-Saharan Africa of these initiatives, and others that might be taken. They find that fully unrestricted access to...

Egyptian economic history has been influenced by the import-substitution industrialization approach to development, dating back to Gamal Abdel Nasser's Pan-Arabic and socialist movement in the 1950s. Two major waves of liberalization have marked the government's efforts to rationalize and...

The proliferation of preferential trade liberalization over the past 20 years has raised the question of whether it slows down multilateral trade liberalization. Recent theoretical and empirical evidence indicates this is the case even for unilateral preferences that industrial countries provide...
