This paper investigates the usefulness of Italian consumer surveys as estimation and forecasting tool over the period 1982-2003. To this end, standard consumption equations are estimated and then compared, in terms of in-sample and out-of-sample predictive ability, with corresponding models...

Investment decision-making is modeled by means of a Kohonen neural net, where neurons represent firms. This is done in order to model investments in novel fields of economic activity, that according to this model are carried out when firms recognize the emergence of a new technological pattern....

For the purpose of determining the influence of the amount of savings circulating in national economy on that economy's growth or drop, a discrete mathematical model with one commodity was developed describing its production as a function of joint investments, depreciation, and introduction of...

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...
