We explore the distortions in business cycle models arising from inefficiencies in price setting and in the search process matching firms to unemployed workers, and the implications of these distortions for monetary policy. To this end, we characterize the tax instruments that would implement...

In this paper, we derive a linear-quadratic model for monetary policy analysis that is consistent with sticky prices and search and matching frictions in the labor market. We show that the second-order approximation to the welfare of the representative agent depends on inflation and "gaps" that...

Recent empirical studies have found that consumption is more sensitive to current income than simple versions of the life-cycle, permanent income hypothesis would predict. The present paper studies a model in which the fraction of consumers exhibiting excess sensitivity is endogenously...

Models in which fiscal and monetary authorities cooperate to minimize the distortionary costs of raising revenue to finance an exogenous stream of government expenditures are shown to have implications for the long-run relationships between government expenditures, tax revenues and seigniorage....
