The standard equilibrium models of business cycles face a puzzling fact that total hours vary greatly over the business cycle without much variation in aggregate wages. The model augments the standard RBC model to include Lucas span of control. Distinction between market and non-market and...

Two investment anomalies in aggregate home-production models are investigated: excess volatility and comovement. Adjustment cost in capital accumulation reduces both volatility and the negative correlation in investments on capital goods in the market and at home. Investments comove to the...

We examine the impact of wage stickiness when employment has an effort as well as hours dimension. Despite wages being predetermined, the labor market clears through the effort margin. Consequently, welfare costs of wage stickiness are potentially much, much smaller

This paper suggests that skill accumulation through past work experience, or "learning-by-doing", can provide an important propagation mechanism for initial shocks, as the current labor supply affects future productivity. Our econometric analysis uses a Bayesian approach to combine micro-level...

At the aggregate level, the labor-supply elasticity depends on the reservation-wage distribution. We present a model economy where workforce heterogeneity stems from idiosyncratic productivity shocks. The model economy exhibits the cross-sectional earnings and wealth distributions that are...

We investigate the mapping from individual to aggregate labor supply using a general equilibrium heterogeneous-agent model with incomplete market. Heterogeneity of the workforce is designed such that the evolution of wages, worker flows between employment and nonemployment, and cross-sectional...

We undertake a quantitative analysis of the dispersion of current accounts in an open economy version of incomplete insurance model, incorporating important market frictions in trade and financial flows. Calibrated with conventional parameter values, the stochastic stationary equilibrium of the...
