We provide evidence on the nature of co-movement in monthly US and UK stock returns by investigating time-varying correlations in returns since 1980. There is a marked increase in correlations between these markets around 2000, which we attribute to globalization and model with a time-varying...

This article proposes a time-varying nonparametric estimator and a time-varying semiparametric estimator of the correlation matrix. We discuss representation, estimation based on kernel smoothing and inference. An extensive Monte Carlo simulation study is performed to compare the semiparametric...

In this paper, we scrutinize the cross-sectional relation between idiosyncratic volatility and stock returns. As a novelty, the idiosyncratic volatility is obtained by conditioning upon macro-finance factors as well as upon traditional asset pricing factors. The macro-finance factors are...

This paper provides evidence on the causes of movements in monthly UK stock prices, examining the role of macroeconomic and financial variables in a nonlinear framework. We allow for time-varying effects through the use of smooth transition models. We find that past changes in the dividend yield...

This paper explores the methodology of regime-switching in the analysis of the income inequality-economic growth relationship. The underlying idea is that when some income determinant passes a certain threshold introduces a new relationship between inequality and income and/or income...

This paper examines the empirical relationship between five European stock market indices and the US market in a smooth transition regression (STR) framework. Due to globalization of economies the motivation is that the New York market has exerted substantial influence on international markets...

This paper models the short-run as well as the long-run relationship between the parallel and official markets for US dollars in Greece in a threshold VECM framework. Modeling exchange rates within this context can be motivated by the fact that the transition mechanism is controlled by the...

This paper models UK stock market returns in a smooth transition regression (STR) framework. A variety of financial and macroeconomic series are employed that are assumed to influence UK stock returns, namely GDP, interest rates, inflation, money supply and US stock prices. STR models are...
