Recent literature has emphasized the importance of transport costs and infrastructure in explaining trade, access to markets, and increases in per capita income. For most Latin American countries transport costs are a greater barrier to U.S. markets than import tariffs. The authors investigate...

The authors develop and estimate a model explaining the level and country-source composition of United States immigration since the early 1970s. The model incorporates ratios of source country income, education, and demographic structure, as well as relative inequality. The authors' model also...

This paper estimates the elasticity of substitution of U.S. imports using detailed trade data over the 1990-2003 period. The authors use a two-stage least squares framework in order to identify the elasticity parameter of interest. The authors use the elasticity estimates to assess the extent to...

The relevance of transport costs has increased as liberalization continues to reduce artificial barriers to trade. Countries need to adopt policies to get closer to global markets. Can improvements in infrastructure and regulation reduce transport costs? Is it worthwhile to implement policies...

More effective development aid could greatly improve poverty reduction in the areas where poverty reduction is expected to lag: Sub-Saharan Africa, Eastern Europe, and Central Asia. Even more potent would be significant policy reform in the countries themselves. The authors develop a model of...

Social welfare functions that assign weights to individuals based on their income levels can be used to document the relative importance of growth and inequality changes for changes in social welfare. In a large panel of industrial and developing countries over the past 40 years, most of the...

When average income rises, the average incomes of the poorest fifth of society rise proportionately. This is a consequence of the strong empirical regularity that the share of income accruing to the bottom quintile does not vary systematically with average income. The authors document this...

The evidence from individual cases and from cross-country analysis supports the view that globalization leads to faster growth and poverty reduction in poor countries. To determine the effect of globalization on growth, poverty, and inequality, the authors first identify a group of developing...

Several recent papers have attempted to identify the partial effects of trade integration and institutional quality on long-run growth using the geographical determinants of trade and the historical determinants of institutions as instruments. The authors show that many of the specifications in...

China has been the most successful developing country in this modern era of globalization. Since initiating economic reform after 1978, its economy has expanded at a steady rate over 8 percent per capita, fueling historically unprecedented poverty reduction (the poverty rate declined from over...
