Informational implications of interest rate rules
Returning to a topic first systematically treated by Poole (1970) in a textbook Keynesian model, this paper compares interest rate and money supply rules. Our analysis, by contrast, is conducted within a rational expectations macro model that incorporates flexible prices and informational frictions. With differential information, interest rate targets can affect the information content of market prices and real activity, but these real consequences can always be replicated by an appropriately chosen money stock rule with feedback to economic activity. However, when the policy authority has ...

Partial adjustment without apology
Many kinds of economic behavior involve discrete and occasional individual choices. Despite this, econometric partial adjustment models perform relatively well at the aggregate level. Analyzing the classic employment adjustment problem, we show how such microeconomic adjustment is well described by a new form of partial adjustment model that aggregates the actions of heterogeneous producers. ; We develop a model where individual establishments infrequently alter the sizes of their workforces because such adjustments involve fixed costs. In the market equilibrium, employment responses to ...

Inflation and real activity with firm-level productivity shocks
In the last ten years there has been an explosion of empirical work examining price setting behavior at the micro level. The work has in turn challenged existing macro models that attempt to explain monetary nonneutrality, because these models are generally at odds with much of the micro price data. In response, economists have developed a second generation of sticky-price models that are state dependent and that include both fixed costs of price adjustment and idiosyncratic shocks. Nonetheless, some ambiguity remains about the extent of monetary nonneutrality that can be attributed to costly ...
