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...

We place regional industry structures at centre stage in currency union analysis, decomposing differences between regional and aggregate cycles into 'industry structure' and 'industry cycle' effects. The industry structure effect indicates whether a region's industry structure causes its cycle...

If two countries experience similar cycles, loss in monetary sovereignty following currency union may not be severe. Analysis of cyclical similarity is frequently carried out at the overall industry level, then interpreted with reference to regional industrial structures. By contrast, this paper...

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.

Potential output figures are important ingredients of many macroeconomic modelsand are routinely applied by policy makers and global agencies. Despite itswidespread use, estimation of potential output is at best uncertain and dependsheavily on the model. The task of estimating potential output...

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...

Many empirical studies have found that interest rate increases have a positive effect on the price level. This paper pursues an obvious, but neglected explanation: interest payments are a cost of production that is at least in part passed on to customers. A model shows that the cost- push effect...

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...
