This paper estimates a DSGE model with learning to re-examine the evidence on time variation in post-war U.S. monetary policy. Several papers document a regime switch, by showing that policy changed from `passive' and destabilizing in the pre-1979 period to `active' and stabilizing in the...

Challenging the conventional wisdom that structural problems are to blame for the euro area’s protracted domestic demand stagnation, this paper sets out to shed some fresh light on the role of the ECB in the ongoing EMU crisis. Contrary to the widely held interpretation of the ECB as an...

This paper examines the impact of macroeconomic policy shocks in a Real- Business-Cycle Model with money. In addition to technology shocks, I include government consumption, government investment, tax rate and monetary policy as sources of random disturbances. Money is introduced in a...

This paper studies the role of collateral constraints in transforming small monetary shocks into large persistent output fluctuations. We do this by introducing money in the heterogeneous-agent real economy of Kiyotaki and Moore (1997). Money enters in a cash-in-advance constraint and is...

Recent empirical results about the US term structure are difficult to reconcile with the classical hypothesis of rational expectations even if time-varying but stationary term premia are allowed for. A hypothesis of rational learning about the conditional variance of the log pricing kernel is...
