Adherents of the"natural trading partner"hypothesis argue that preferential trade agreements (PTAs) are more likely to improve welfare if participating countries already trade disproportionately with each other. Opponents of the hypothesis claim that the opposite is true: welfare gains are...

The authors review several studies of the aggregate agricultural supply response. Using both economic and econometric reasons, they argue that time series estimation typically generates a downward-biased estimate of the response to a credible reform. Even though time series estimates can provide...

The author considers the policy options of the West Bank and Gaza with respect to trade and the export of labor services. He concludes that: 1) Nondiscriminatory trade policy is unambiguously superior to a free trade agreement with Israel; 2) The West Bank and Gaza should pursue a...

Regional integration agreements (RIAs) are examples of second best and have an ambiguous impact on welfare, contend the authors. They build a model in which RIAs unambiguously raise welfare by correcting for externalities. It assumes that trade between neighboring countries increases trust...

In this paper, developed as part of the World Bank's Poverty Reduction Strategy Sourcebook, the authors examine how to implement trade liberalization as part of a strategy for alleviating poverty in developing countries. They discuss trade policy instruments, institutions, complementary...

The author examines the impact of various trade policies for small developing states in the face of changing international trends - including globalization, the proliferation of regional integration agreements, the changing relationship between African, Caribbean, and Pacific (ACP) countries and...

Before 1973, the labor market in Europe was tight and immigration from the South (chiefly North Africa and Southern Europe) was encouraged. But with the slowdown in growth in the mid-1970s, the rise in unemployment, and increased economic uncertainty, immigration came to be viewed as a burden by...

Policymakers typically assume that trade liberalization and foreign aid ultimately reduce international migration - that is, that trade and aid are substitutes for migration. In the Heckscher-Ohlin framework, too, trade liberalization (by reducing international price differentials between...

Labor market integration is typically assumed to improve welfare in the absence of distortions, because it allows labor to move to where returns are highest. The author examines this result in a simple general equilibrium model in the presence of a common property resource: social capital....

In the standard Heckscher-Ohlin model, trade and migration are substitutes (that is, migration decreases with trade liberalization). The authors add four factors to the standard Heckscher-Ohlin model: labor skill levels (skilled or unskilled), international labor mobility, migration costs, and...
