Factor-augmented VARs (FAVARs) have combined standard VARs with factor analysis to exploit large data sets in the study of monetary policy. FAVARs enjoy a number of advantages over VARs: they allow a better identification of the monetary policy shock; they avoid the use of a single variable to...

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...

What brings persistence into the macroeconomy? This is one of the big unresolved issues in current macroeconomic theory. Economic models, in fact, typically struggle to imply levels of persistence comparable to those observed in the data. Most of the persistence is therefore introduced by highly...

In recent years, the learnability of rational expectations equilibria (REE) and determinacy of economic structures have rightfully joined the usual performance criteria among the sought-after goals of policy design. Some contributions to the literature, including Bullard and Mitra (2001) and...

Expected exchange rate changes are determined by interest rate differentials across countries and risk premia, while unexpected changes are driven by innovations to macroeconomic variables, which are amplified by time-varying market prices of risk. In a model where short rates respond to the...

We study markets where innovators can sell ideas to entrepreneurs, who may be better at implementing them. These markets are decentralized, with random matching and bargaining. Entrepreneurs hold liquid assets lest potentially profitable opportunities may be lost. We extend existing models of...

This paper studies the long run effects of monetary policy in a micro-founded model with trading frictions and endogenous market segmentation. Agents must pay a fixed cost to participate in a centralized liquidity market. By endogenizing the participation decision, this model endogenizes the...

We study how the use of judgement or add-factors in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which "exuberance equilibria" exist in standard macroeconomic environments. These equilibria may...
