"Studying the incentives and constraints in the non-market sector--that is, home production--enhances our understanding of economic behavior in the market. In particular, it helps us to understand (1) small variations of labor supply over the life cycle, (2) large variations of employment...

"Whether technological progress raises or lowers aggregate employment in the short run has been the subject of much debate in recent years. Using a simple model of industry employment, we show that cross-industry differences of inventory holding costs, demand elasticities, and price rigidities...

"This paper assesses biases in policy predictions due to the lack of invariance of "structural'' parameters in representative-agent models. We simulate data under various fiscal policy regimes from a heterogeneous-agents economy with incomplete asset markets and indivisible labor supply....

We construct a family model of labor supply that features adjustment along both the in- tensive 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...

We introduce worker differences in labor supply, reflecting differences in skills and assets, into a model of separations, matching, and unemployment over the business cycle. Separating from employment when unemployment duration is long is particularly costly for workers with high labor supply....
