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...

Despite the predictions of standard trade theory, countries in the North are not indifferent about free migration and free trade. Migration has become a major concern in some OECD (Organization for Economic Cooperation and Development) countries. But is migration really a threat? If free trade...

A number of studies have examined the implications of preference interdependence. This paper models individual utility as depending either on the level of other people's consumption or on the difference in consumption levels. It assumes that the impact of an increase in other people's...

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...

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...

Based on an economy-wide perspective, this paper begins with a discussion of the bias against exports and agriculture that characterized the economic literature and the development strategies in many developing countries after World War II. This is followed by an analysis of how the...

Past studies have identified nutrition exclusively with nutrient intake. A better definition of nutrition would critically affect the link between poverty and malnutrition and would affect the implications for policies designed to improve the nutritional status of the poor. This paper focuses on...
