Standard sticky information pricing models successfully capture the sluggish movement of aggregate prices in response to monetary policy shocks but fail at matching the magnitude and frequency of price changes at the micro level. This paper shows that in a setting where firms choose when to...

Optimal monetary policy depends crucially on whether agents have exogenous, endogenous-inelastic, or endogenous-elastic attention. We show in this paper that, under elastic attention, optimal monetary policy may induce equilibria that are not possible under the other two settings: decision...

This paper studies the implication, in terms of welfare and monetary policy, of unequal degrees of competition across members of a currency area. We look at two ways in which the degree of competition in the market for goods can affect welfare in a currency area. One is through different average...

I construct a simple model with sticky prices and interest rate targets, closed by fiscal theory of the price level with long-term debt and fiscal and monetary policy rules. Fiscal surpluses rise followingperiods of deficit, to repay accumulated debt, but surpluses do not respond to arbitrary...

Macroeconomic and microeconomic data paint conflicting pictures of price behavior. Macroeconomic data suggest that inflation is inertial. Microeconomic data indicate that firms change prices frequently. We formulate and estimate a model which resolves this apparent micro - macro conflict. Our...

In many developing and emerging market economies, governments intervene to limit the degree to which oil-price increases are passed through to domestic fuel prices. This paper investigates whether, and to what extent, this intervention is warranted in an oil-importing economy characterized by...

This paper studies the effect on monetary policy of differing degrees of competition and differing degrees of nominal rigidity between the members of a monetary union. In particular, we assess the welfare loss brought about by the use of a simple interest rate rule that does not take into...

This paper investigates the effects generated by limited asset market participation on optimal monetary and fiscal policy, where monetary and fiscal authorities are independent and play strategically. It shows that: (i) both the long run and the short run equilibrium require a departure from...

We reconsider the New Keynesian model with staggered price setting when each market is characterized by a small number of firms competing in prices à la Bertrand rather than a continuum of isolated monopolists. Price adjusters change their prices less when there are more firms that do not...
