We develop a simple Hotelling spatial-trade model of price dispersion to examine how distance-related costs affect price dispersion, and we offer some insights on how such costs may best be inferred from price-dispersion measures. Our theoretical model suggests that measures of price dispersion...

This paper brings the elements of growth to the standard New Keynesian model to analyze the optimal rate of inflation. To our knowledge, this is the first theoretical attempt to consider the effects of growth in the determination of optimal monetary policies. With both elements of price and wage...

In this paper, we explore the benefits from a supply-side oriented fiscal tax policy within the framework of a New Keynesian DSGE model. We show that countercyclical tax rules, which are contingent on the observed welfare gap or alternatively on the markup shock and levied on value added, reduce...

We analyze a model of price competition ά la Bertrand in a network environment. Firms only have a limited information on the structure of network: they know the number of potential customers they can attract and the degree distribution of customers. This incomplete information framework...

We study models that combine search, monetary exchange, price posting by sellers, and buyers with preferences that differ across random meetings; say, because sellers in different meetings produce different varieties of the same good. We show how these features interact to influence the price...

Presented is an analytic microeconomic model of the temporal price dispersion of homogeneous goods in polypoly markets. This new approach is based on the idea that the price dispersion has its origin in the dynamics of the purchase process. The price dispersion is determined by the chance that...

Persistent responses of inflation to monetary policy shocks have been difficult to explain by existing models of the monetary transmission mechanism without embedding controversial intrinsic inertia of inflation. Our paper addresses this issue using a staggered price model with trend inflation,...
