The first objective of this chapter is to present a new approach to econometric modeling of producer behavior. Our key contribution is to represent the rate and biases of technical change by unobservable or latent variables. We also divide the rate of technical change between components that are...

We propose a new explanation for differences and changes in labor supply by gender and marital status, and in particular for the increase in married women's labor supply over time. We argue that this increase as well as the relative constancy of other groups' hours are optimal reactions to...

Standard real business cycle models must rely on total factor productivity (TFP) shocks to explain the observed comovement of consumption, investment, and hours worked. This paper shows that a neoclassical model consistent with observed heterogeneity in labor supply and consumption can generate...

This paper analyzes the role of heterogeneous households in propagating shocks over the business cycle by generalizing a basic sticky-price model to allow for imperfect risk-sharing between households that differ in labor incomes. I show that imperfectly insured household consumption distorts...

In this paper, we develop heterogeneous agent models with equilibrium unemployment to study the optimal taxation and labour wedge. We find that the the presence of profits plays an important role in the determination of both optimal tax policy and labour wedge. Judd-Chamley optimal zero capital...

In this paper we compare, in a fully consistent manner, micro and macro labor supply elasticities. The individual elasticity is obtained from the Panel Study of Income Dynamics (PSID). The aggregate, time-series, elasticity is estimated from the aggregation of individual units in the PSID for...
