Our thesis is that poor countries are poor because they employ arrangements for which the equilibrium outcomes are characterized by inferior technologies being used, and being used inefficiently. In this paper, we analyze the consequences of one such arrangement. In each industry, the...

Recent studies argue that cross-country labor productivity differences are much larger in agriculture than in the aggregate. We reexamine the agricultural productivity data underlying this conclusion using new evidence from disaggregate sources. We find that for the world's staple...

We assess the empirical importance of changes in income and relative prices for structural transformation in the postwar United States. We explain two natural approaches to the data: sectors may be categories of final expenditure or value added; e.g., the service sector may be the final expenditure...

Many states are implementing school-finance reforms which will have complex effects on income distribution, intergenerational income mobility, and welfare. This paper analyzes the static and dynamic effects of such reforms by constructing a dynamic general equilibrium model of public-education...

We construct a family model of labor supply that features adjustment along both the intensive and extensive margin. Intensive margin adjsutment is restricted to two values: full-time work and part-time work. Using simulated data from the steady state of the calibrated model, we examine whether...

We consider two life cycle models of labor supply that use nonconvexities to generate retirement. In each case we derive a link between hours worked prior to retirement, the intertemporal elasticity of substitution for labor (IES), and the size of the nonconvexities. This link is robust to...
