Expanding on an approach suggested by Ashenfelter (1984), we extend the Phillips curve to an open economy and exploit panel data to estimate the textbook 'expectations augmented' Phillips curve with a market-based and observable measure of inflation expectations. We develop this measure using...

Several academics and practitioners have pointed out that inflation follows a seemingly exogenous statistical process, unrelated to the output gap, leading some to argue that the Phillips curve has weakened or disappeared. In this paper we explain why this seemingly exogenous process arises, or,...

This paper investigates whether permanent monetary tightenings increase inflation in the short run. It estimates, using U.S. data, an empirical and a New-Keynesian model driven by transitory and permanent monetary and real shocks. Temporary increases in the nominal interest-rate lead, in...

The "reversal interest rate" is the rate at which accommodative monetary policy reverses its intended effect and becomes contractionary for lending. It occurs when banks' asset revaluation from duration mismatch is more than offset by decreases in net interest income on new business, lowering...

We propose a supply-side channel for the transmission of monetary policy. We study an economy with heterogeneous firms, sticky prices, and endogenous markups. We show that if, as is consistent with the empirical evidence, bigger firms have higher markups and lower pass-throughs than smaller...

We propose a monetary model in which the unemployed satisfy the official US definition of unemployment: they are people without jobs who are (i) currently making concrete efforts to find work and (ii) willing and able to work. In addition, our model has the property that people searching for...

This paper surveys the research in the past decade on imperfect information models of aggregate supply and the Phillips curve. This new work has emphasized that information is dispersed and disseminates slowly across a population of agents who strategically interact in their use of information....

The paper provides an integrated analysis of globalization effects on the inflation-output tradeoff and monetary policy in the New-Keynesian framework. The prediction of the analysis is threefold. First, labor, goods, and capital mobility flatten the Phillips curve, the tradeoff between...

This paper compares the P-bar model of price adjustment with the currently dominant Calvo specification. Theoretically, the P-bar model is more attractive as it depends upon adjustment costs for physical quantities rather than nominal prices, while incorporating a one-period information lag....

We construct a utility-based model of fluctuations, with nominal rigidities and unemployment, and draw its implications for the unemployment-inflation tradeoff and for the conduct of monetary policy.<br><br>We proceed in two steps. We first leave nominal rigidities aside. We show that, under a standard...
