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 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...

We model unemployment allowing workers to differ by comparative advantage in market work. Workers with comparative advantage are identified by who works more hours when employed. This enables us to test the model by grouping workers based on their long-term wages and hours from panel data. The...

Many successful examples of economic development, such as South Korea, exhibit long periods of sustained capital accumulation. This process is characterized by a gradually rising investment rate along with a moderate rate of return to capital, both of which are strongly at odds with the standard...

We consider a matching model of employment with wages that are flexible for new hires, but sticky within matches. We depart from standard treatments of sticky wages by allowing effort to respond to the wage being too high or low. Shimer (2004) and others have illustrated that employment in the...

We identify the cyclical turning points of 74 U.S. manufacturing industries and uncover new empirical regularities: (i) Cyclical phase shifts are highly concentrated around the aggregate turning points; (ii) In contrast to the conventional notion of a ‘sudden stop and slow recovery,’ troughs...
