According to recent UN projections more than 50 percent of the growth in world population over the next half century will be due to population growth in Africa. Given this, any policy that influences African demography will have a significant impact on the world distribution of income. In this...

This paper develops a long-run growth model for a major oil exporting economy and derives conditions under which oil revenues are likely to have a lasting impact. This approach contrasts with the standard literature on the "Dutch disease" and the "resource curse", which primarily focuses on...

We show that the main nonparametric identification finding of Abbring and Van den Berg (2003b, Econometrica) for the effect of a timing-chosen treatment on an event duration of interest does not hold. The main problem is that the identification is based on the competing-risks identification...

This paper proposes a causal decomposition framework for settings in which an initial regime randomization influences the timing of a treatment duration. The initial randomization and treatment affect in turn a duration outcome of interest. Our empirical application considers the survival of...

Quantile regression and quantile treatment effect methods are powerful econometric tools for considering economic impacts of events or variables of interest beyond the mean. The use of quantile methods allows for an examination of impacts of some independent variable over the entire distribution...

This paper integrates institutionally determined wage rigidities into an otherwise standard Heckscher-Ohlin model of international trade. It accounts for differences in individual productivities and their implications for individual wage incomes and demand for education. Although preserving the...

We use a version of the Meade model to consider the effects of interdependent import tariffs in the presence illegal immigration. First, we consider the small union case and derive the Nash tariff equilibrium for two potential members of a Preferential Trade Agreement (PTA). We analyze...

Trade liberalization is often met with sharp opposition. Recent examples include the so-called "Bolkestein" directive, which allows service providers from a given EU member to temporarily work in another member country. One way to view such a reform is that it simply widens the range of goods...

This study examines the effect of NAFTA, an instance of North-South trade liberalization, on returns to skill in Mexico. Mexico is abundant in low-skill workers relative to the US and Canada, and so, by the Hecksher-Ohlin-Samuelson trade model, NAFTA ought to have raised the relative earnings of...

In a two-sector, general-equilibrium model with labor-market search frictions, we find that wage increases and sectoral unemployment decreases upon offshoring in the presence of perfect intersectoral labor mobility. If, as a result, labor moves to the sector with the lower (or equal) vacancy...
