Much of the recent economic debate about the impact of stimulus packages has focused on the size of the crucial government purchases multiplier. But equally crucial is the size of the government purchases multiplicand--the change in government purchases of goods and services that the multiplier...

Research in the early 1980s found that the gains from international coordination of monetary policy were quantitatively small compared to simply getting domestic policy right. That prediction turned out to be a pretty good description of monetary policy in the 1980s, 1990s, and until recently....

We first document a large secular shift in the estimated response of the entire term structure of interest rates to inflation and output in the United States. The shift occurred in the early 1980s. We then derive an equation that links these responses to the coefficients of the central bank's...

This paper shows that the theory of monetary policy rules is able to explain, predict, and help understand a variety of phenomenon in macroeconomics and finance, including the Great Moderation, the correlation between exchange rates and interest rates, and the shift in the response of the term...

This paper is a review of rational expectations models used in macroeconomic research. The purpose is to examine in some detail the differences between the models, the advantages and disadvantages of alternative models the empirical support for the models and their policy implications. The main...

This paper reviews the state of the debate over rules versus discretion in monetary policy, focusing on the role of economic research in this debate. It shows that proposals for policy rules are largely based on empirical research using economic models. The models demonstrate the advantages of a...

In this paper we investigate the comparative properties of empirically-estimated monetary models of the U.S. economy. We make use of a new data base of models designed for such investigations. We focus on three representative models: the Christiano, Eichenbaum, Evans (2005) model, the Smets and...

This paper is an empirical investigation of the role of government actions and interventions in the financial crisis that flared up in August 2007. It integrates and summarizes several ongoing empirical research projects with the aim of learning from past policy. The evidence is presented in a...

At the center of the financial market crisis of 2007-2008 was a highly unusual jump in spreads between the overnight inter-bank lending rate and term London inter-bank offer rates (Libor). Because many private loans are linked to Libor rates, the sharp increase in these spreads raised the cost...

This paper is an expository review of recently developed techniques that are designed to evaluate macroeconomic policy using econometric models ; The exposition focuses on dynamic stochastic models with rational expectations and with discrete time. The method of undetermined coefficients is used...
