In a former research group 1 where I worked (1996 to 1999), the core of the study was to compare the four southern European housing systems - Portugal, Spain, Italy and Greece Πunder the assumption that they had a different path other than northern European countries. We had the personal...

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

This paper investigates the asymmetric effects of monetary shocks when the=20 impact of monetary policy on real activity works through state-dependent=20 variables. We use a nonlinear model, the multiple regime smooth transition=20 autoregressive model, that allows the effects of shocks to vary...

This paper considers a sticky price model with a cash-in-advance constraint where agents forecast inflation rates with the help of econometric models. Agents use least squares learning to estimate two competing models of which one is consistent with rational expectations once learning is...

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 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...

Using a recently introduced nonparametric test, I investigate two important and distinct asymmetries in cross-country quarterly macroeconomic time series. Asymmetries are suggested by many theories (old and new), and those discovered aid in the selection of the appropriate nonlinear time series...

This paper assesses the information content of two survey indicators for consumption developments in the near future for eight European countries in the period 1985-1998. Empirical work on this topic typically focuses on consumer confidence, the perceptions of buyers of consumption goods. This...
