Research aimed at explaining the greater persistence of unemployment in European countries relative to the US has found higher employment adjustment costs in Europe to be a significant contributing factor. This paper explores the potential for costly adjustment of labour to explain at least some...

There is substantial empirical literature which examines the relationship between private and public consumption. The conclusions from this literature, however, are generally mixed. In this paper, we attempt to provide some additional evidence on this relationship. We consider a two-good...

Simulation evidence is presented on the finite sample properties of two tests for stationarity recently proposed by Kwiatkowski, Phillips and Schmidt (1991) and Park (1990). Unlike earlier unit-root tests, these test the null of stationarity against the alternative of a unit root, thereby...

We examine whether a link exists between oil price shocks and the U.S. real effective exchange rate. The results show that the two variables appear to be cointegrated and that causality runs from oil prices to the exchange rate and not vice versa. The single-equation error-correction model...

This paper proposes a variant of a threshold stochastic conditional duration (TSCD) model for financial data at the transaction level. It assumes that the innovations of the duration process follow a threshold distribution with a positive support. In addition, it also assumes that the latent...

This paper studies multiscale stochastic volatility models of financial asset returns. It specifies two components in the log-volatility process and allows for leverage/asymmetric effects from both components while return innovation terms follow a heavy/fat tailed Student t distribution. The two...
