Euler equation models represent an important class of macroeconomic systems. Our research on the Leeper and Sims Euler equations macroeconomic model reveals the existence of singularity-induced bifurcations, when the model's parameters are within a confidence region about the parameter...

This paper is a follow-on to our earlier paper, "Bifurcations in Continuous-Time Macroeconomic Systems." In this paper, we determine the stability properties of the UK continuous time macroeconometric model on its bifurcation boundaries and we test the null hypothesis that the model's parameters...

Grandmont (1985) found that the parameter space of even the simplest, most classical models is stratified into bifurcation regions. But in such classical models all policies are Ricardian equivalent and all solutions are Pareto optimal. As a result he was not able to reach conclusions about...

This research investigates bifurcation phenomena in a continuous-time model of the United Kingdom. We use the Bergstrom, Nowman, and Wymer continuous-time dynamic macroeconometric model of the UK economy. We find that bifurcations are important with this model for understanding the dynamic...

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...

This paper is a follow on to our earlier papers exploring the dynamic properties of the UK continuous time macroeconometric model. This paper is focussed on policy implications. We take the position that the term "stabilization policy" implies that the economy would be unstable without policy,...

This paper reports on unsolved problems in our research on testing for nonlinearity and chaos and for designing bifurcation stabilization policies conditional upon macroeconomic models.

This is the front matter from the book, William A. Barnett and Apostolos Serletis (eds.), The Theory of Monetary Aggregation, published in 2000 by Elsevier in its Contributions to Economic Anaysis mongraph series. The front matter includes the Table of Contents and the Introduction by Barnett...

We measure the United States capital stock of money implied by the Divisia monetary aggregate service flow, in a manner consistent with the present-value model of economic capital stock. We permit non-martingale expectations and time varying discount rates. Based on Barnett’s (1991) definition...

This paper is a comment on Serletis and Shintani, 'Chaotic Monetary Dynamics with Confidence,' which is to appear in a special issue of the Journal of Macroeconomics on chaos in economics. The Editor of the special issue invited comments from discussants of all papers in the special issue, with...
