We study the responses of real and nominal prices to random flutuations in costs and money growth using a monetary search economy in which there are no costs or temporal restrictions on sellers' ability to change prices. The economy exhibits a form of price stickiness in that the price level may...

The short-run non-neutrality of money and its implications for inflation dynamics are examined in a monetary search economy with heterogeneous agents. Lump-sum money injections affect the distribution of money holdings in equilibrium and thus generate short-run non-neutrality. The response of...

We examine the implications of inflation for both price dispersion and welfare in a monetary search economy. In our economy, if the degree of buyers' incomplete information about prices is fixed, both price dispersion and real prices are increasing in inflation. As the inflation rate approaches...

We develop and estimate a search model in which identical consumers trade with price-setting firms that differ in productivity. In the model, equilibrium distributions of both prices and markups are non-degenerate and continuous with a firm's price decreasing as its productivity increases....

This thesis covers three issues: the aggregate and welfare effects of environmental policies when plants are heterogeneous; what causes the different patterns of employment dynamics in small versus large firms over business cycles; and the welfare costs of expected and unexpected inflation. In...
