We construct a family model of labor supply that features adjustment along both the intensive and extensive margin. Intensive margin adjustment 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...

Agriculture's share of economic activity is known to vary inversely with a country's level of development. This paper examines whether extensions of the neoclassical growth model can account for some important sectoral patterns observed in a current cross-section of countries and in the time...

A longstanding question in economics is why some countries are so much richer than others. Today, for example, income per capita in the world's richest countries is roughly thirty-five times greater than it is in the world's poorest countries. Recent work argues that the proximate cause of the...

Structural transformation refers to the reallocation of economic activity across the broad sectors agriculture, manufacturing, and services. This review article synthesizes and evaluates recent advances in the research on structural transformation. We begin by presenting the stylized facts of...

We show that a life cycle model with home production implies a tight relationship between key preference parameters and the changes in time allocated to home production and leisure at retirement. We derive this relationship and use data from the ATUS to explore its quantitative implications. Our...

We develop a heterogeneous-agent general equilibrium model that incorporates both intensive and extensive margins of labor supply. A nonconvexity in the mapping between time devoted to work and labor services distinguishes between extensive and intensive margins. We consider calibrated versions...

We develop a model featuring search frictions and a nondegenerate labor supply decision along the extensive margin, and argue that it does a reasonable job of matching labor market flows between employment, unemployment and out of the labor force. Persistent idiosyncratic productivity shocks...

We analyze the forces that can generate retirement in different versions of standard life cycle models of labor supply. While nonconvexities in production can generate retirement, we show that the size of nonconvexities needed increases sharply as the intertemporal elasticity of substitution for...

We document large differences across OECD countries in fluctuations of the intensive and extensive margin of labor supply over the business cycle. Countries with larger fluctuations in employment relative to hours per worker tend to display larger fluctuations in total hours worked. These facts...
