This paper implements a new statistical approach to robust regression with nonstationary time series. The methods are presently under theoretical development in other work, and are briefly exposited here. They allow us to perform regressions in levels with nonstationary time series data, they...

This paper provides a robust statistical approach to testing the unbiasedness hypothesis in forward exchange market efficiency studies. The methods we use allow us to work explicitly with levels rather than differenced data. They are statistically robust to data distributions with heavy tails,...

We examine the role and nature of external influences (US as well as German) and changing institutional constraints upon UK monetary policy by estimating Taylor-type reaction functions for three subperiods: 1985-90 (pre-ERM), 1992-97 (post-ERM) and 1997-2000 (MPC). We identify and contrast...

This paper uses Markov-switching techniques to examine the presence of different market conditions on the Shanghai A-share market since the start of active trading in the mid-1990s. The originality of the paper lies in the identification of three contrasting regimes: a speculative market, a bull...

This paper examines the effect of financial deregulation on consumption expenditure in France during the period 1970-1993. A nonlinear model for consumption which allows for liquidity constraints through a time-varying parameter dependent on a proxy for financial deregulation is estimated using...

In spite of high trade openness, existing empirical work, using daily data, has not found any evidence of international financial integration of China. In this paper we examine to what extent the Chinese A-share market, de jure protected from foreign influences by capital controls, is actually...
