Introducing the publication of a long 1956 letter by Franco Modigliani (FM) to Paolo Sylos Labini (PSL) on the draft of PSL's book, Oligopoly and Technical Progress, the paper critically reviews the theoretical background of FM's comments, showing how the pre-Keynesian roots dominate the...

The distributional and disruptive effects of energy supply shocks are potentially large. We study the effectiveness of alternative fiscal responses in a two-country HANK model that we calibrate to the euro area. Energy subsidies can stabilize the domestic economy, but are fiscally costly and...

In this paper we estimate a simple New-Keynesian DSGE model with German data for the sample period 1970:q1 to 1998:q4. Contrary to a number of recent similar papers estimated with US and euro-area data, we find that real money balances contribute significantly to the determination of inflation...

This paper proposes a simple framework for analyzing a continuum of monetary policy rules characterized by differing degrees of credibility, in which commitment and discretion become special cases of what we call quasi commitment. The monetary policy authority is assumed to formulate optimal...

New Keynesian models of monetary policy assign no role to monetary aggregates, in the sense that the level of output, prices, and interest rates can be determined without knowledge of the quantity of money. We evaluate the empirical validity of this prediction by studying the effects of shocks...

We estimate a New-Keynesian macro model accommodating regime-switching behavior in monetary policy and in macro shocks. Key to our estimation strategy is the use of survey - based expectations for inflation and output. We identify accommodating monetary policy before 1980, with activist monetary...
