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...

The efficiency of speculative markets, as represented by Fama's 1970 fair game model, is tested on weekly price index data of six Asian stock markets - Hong Kong, Indonesia, Malaysia, Singapore, Taiwan and Thailand - using Sherry's (1992) non-parametric methods. These scientific testing methods...

This paper analyses changes in the distribution of equivalised gross household income and income inequality in New Zealand between 1983 and 1998. We analyse the distributional effects of changes in household structure, National Superannuation (old age pension), household socio- demographic...

This study examines the effect of research and development subsidies on the private funding of R&D in France. We address this issue from the annual R&D survey over 1985-1997, which provides information about the R&D subsidies given by all the ministries to the firms having at least one full-time...

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...

Based on administrative data from the federal employment office in Germany, we apply matching techniques to estimate the stepping-stone function of temporary agency work for the unemployed, i.e. its short-run and long-run effects on their future employment prospects. Our results show that...

In April 2001 Swiss banks held over CHF 500 billion in mortgages. This important segment accounts for about 63\% of all the loan portfolios of Swiss banks. In this paper we restrict our attention to residential mortgages held by private clients, i.e. borrowers who finance their property by the...

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 re-examines evidence relating mean inflation to cross- sectional inflation asymmetry, and investigates longitudinal asymmetry in disaggregated price series. The asymmetry test used possesses two important characteristics: it has high power, and it is not dominated by outliers. In...

Prices of currency options commonly differ from the Black-Scholes formula along two dimensions: implied volatilities vary by strike price (volatility smiles) and maturity (implied volatility of at­the­money options increases, on average, with maturity). We account for both using Gram­Charlier...
