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 documents a new stylized fact of the U.S. greater macroeconomic stability of the last two decades or so. Using 131 monthly time series, three popular statistical methods and the forecasts of the Federal Reserve's Green book and the Survey of Professional Forecasters, we show that the...

This paper models an inflation forecast density framework that closely resembles actual policy makers behaviour regarding the determination of the modal point, the uncertainty and asymmetry in the inflation forecasts. The framework combines policy makers prior information about these parameters...

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 was produced for the El-Naschie Symposium on Nonlinear Dynamics in Shanghai in December 2005. In this paper we provide a review of the literature with respect to fluctuations in real systems and chaos. In doing so, we contrast the order and organization hypothesis of real systems with...

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...

The anemic U.S. economic recovery and the threat of a double-dip recession stem from the weakness of investment, due to excess capacity created in the euphoric years of the "new economy" bubble. The current imbalances in the corporate sector (i.e., the all-time-high indebtedness in the face of...

The consumer has been on a tightrope since the bursting of the "new economy" bubble, as losses in equity markets have been partly offset by gains in real estate and fiscal support and mortgage refinancing have partly offset increased consumer cautiousness. The consumer will remain on a tightrope...
