In this paper we report the results of the estimation of a rich dynamic stochastic general equilibrium (DSGE) model of the U.S. economy with both stochastic volatility and parameter drifting in the Taylor rule. We use the results of this estimation to examine the recent monetary history of the...

We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal deficits and public debt have risen sharply in the wake of the financial crisis. While these developments make fiscal consolidation inevitable, there is considerable uncertainty about...

This paper compares the role of stochastic volatility versus changes in monetary policy rules in accounting for the time-varying volatility of U.S. aggregate data. Of special interest to us is understanding the sources of the great moderation of business cycle fluctuations that the U.S. economy...

This thesis consists of four self-contained papers related to banking, credit markets and financial stability. Paper [I] presents a credit market model and finds, using an agent based modeling approach, that credit crunches have a tendency to occur; even when credit markets are almost entirely...

This paper analyses the use of factor analysis for instrumental variable estimation when the number of instruments tends to infinity. We consider cases where the unobserved factors are the optimal instruments but also cases where the factors are not necessarily the optimal instruments but can...

In this paper, we perform a structural Bayesian estimation of the contribution of anticipated shocks to business cycles in the postwar United States. Our theoretical framework is a real-business-cycle model augmented with four real rigidities: investment adjustment costs, variable capacity...

The evolution of Spanish unemployment has been quite idiosyncratic. The full-employment levels of the early seventies were followed by unemployment rates that were the highest within the OECD countries in the aftermath of the oil price shocks. While unemployment was extremely persistent in most...

Investment-driven growth has long been regarded as a key development strategy in China. This paper investigates empirically the validity of this view. Post-1990 data analyses and macroeconometric model simulations show that market demand has become a regular force in driving investment since...

Using firm-level survey data for the West German manufacturing sector, this paper revisits the technology-driven business cycle hypothesis for the case of aggregate investment. We construct a survey-based measure of technology shocks to gauge their contribution to short-run investment...

We review recent evidence on price rigidity from the macroeconomics literature, and discuss how this evidence is used to inform macroeconomic modeling. Sluggish price adjustment is a leading explanation for large effects of demand shocks on output and, in particular, the effects of monetary...
