Potential costs and benefits of a monetary union for the four MERCOSUR countries Argentina, Brazil, Paraguay and Uruguay are compared. Particular emphasis was put on the traditional and new approaches to optimum currency area theory which were reviewed and analyzed with respect to their validity...

Euler equation models represent an important class of macroeconomic systems. Our ongoing research (He and Barnett (2003)) on the Leeper and Sims (1994) Euler equations macroeconometric model is revealing the existence of singularity-induced bifurcations, when the model’s parameters are within...

A reliable leading indicator should possess the following properties: (1) The movements in the indicator series should resemble those in the business cycle reference series. (2) The relation between the reference series and the indicator should be statistically significant and stable over time....

Most studies that emphasize and encourage the shift towards a less regulated and financially open system rest on the premise of a prosperous growth prospect. Accordingly, interests have focused on growth models as a framework to understand and to analyze the effects of economic freedom. In this...

We examine the response of a sticky-wage economy to various real and nominal shocks. In addition to variations in hours, we allow for an endogenous response in worker effort per hour. Despite wages being predetermined, the labor market clears through the effort margin. We find that the ability...

We examine the impact of wage stickiness when employment has an effort as well as hours dimension. Despite wages being predetermined, the labor market clears through the effort margin. Consequently, welfare costs of wage stickiness are potentially much, much smaller.

This paper is on monetary policy transmission. First, it asks the question whether industries are affected differently by monetary policy shocks. Here both output and price effects are compared. Second, some industry characteristics are explored which may help to understand the existence of...

This paper examines a mechanism of liquidity-preference fluctuations caused by people's learning behavior. % about the frequency of a liquidity shock. When observing a financial shock, they rationally update their belief so that the subjective probability of encountering it again is higher,...

Modern monetary policy analysis is built around the concept of an interest rate rule that responds to both inflation and output. This paper evaluates the quantitative implications of having a policy rule target different definitions of the output gap in a New Keynesian model with endogenous...

In this paper we reconcile two opposing views about the elasticity of intertemporal substitution in consumption (EIS). Empirical studies using aggregate consumption data typically find that the EIS is close to zero (Hall, 1988). Calibrated models designed to match growth and fluctuations facts...
