Employment volatility is larger for young workers than for prime aged. At the same time, in economies with high tax rates the share of total market hours supplied by the young workers is smaller. These two observations imply a negative correlation between government size (measured by the share...

We analyze the welfare cost of inflation in a model with cash-in-advance constraints and an endogenous distribution of establishments' productivities. Inflation distorts aggregate productivity through firm entry dynamics. The model is calibrated to the United States economy and the long-run...

The specification of an optimizing model of the monetary transmission mechanism requires selecting a policy regime, commonly commitment or discretion. In this paper we propose a new procedure for testing optimal monetary policy, relying on moment inequalities that nest commitment and discretion...

There is substantial evidence of a negative correlation between government size and output volatility. We put forward the hypothesis that large governments stabilize output fluctuations because in economies with high tax rates the share of total market hours supplied by demographic groups...

I study the impact of idiosyncratic earnings uncertainty on aggregate saving and employment in an economy populated by families consisting of two members. Families incur a fixed cost of participation when both members are employed. I argue that, because of market incompleteness and private...
