This paper analyzes the conditions under which power gains can be achieved using the Covariate Augmented Dickey-Fuller test (CADF) rather than the conventional Augmented Dickey-Fuller (ADF), and argues that this method has the advantage, relative to univariate unit root tests, of increasing...

We analyse whether tests of PPP exhibit erratic behaviour (as previously reported by Caporale et al., 2003) even when (possibly unwarranted) homogeneity and proportionality restrictions are not imposed, and trivariate cointegration (stage-three) tests between the nominal exchange rate, domestic...

In this article, we carry out unit root tests on real exchange rates recursively as in Caporale et al. (2003), but, following Arghyrou and Gregoriou (2007), we adjust the residuals for non-normality and heteroscedasticity using a wild bootstrap method. The results are striking: this correction...

The present study examines a series of performance measures with the aim of solving the ex-post verification problem. These measures are employed to test the performance persistence hypothesis of domestic equity funds in Greece, during the period 1998-2004. Correctly adjusting for risk factors...

Using Monte Carlo simulations, it is shown that fitting a mis-specified GARCH model to a true MS-GARCH process tends to produce IGARCH parameter estimates. In other words, the presence of structural breaks can result in spuriously high estimates of the degree of persistence of shocks to the...

This paper reexamines the relationship between consumer and producer prices in the G7 countries (United States, Canada, Germany, France, Italy, United Kingdom, and Japan), and it improves on the existing literature in two ways. First, it takes into account causality links arising from the...

In this study we examine the widely used Brock, Dechert, and Scheinkman (BDS) test when applied to the logarithm of the squared standardized residuals of an estimated GARCH(1,1) model as a test for the adequacy of this specification. We review the conditions derived by De Lima (1996; Econometric...

This paper uses data from a panel of more than 400 Italian banks for the period 2001 – 2012 to examine the main determinants of loan loss provision (LLP), which are classified as either discretionary (income smoothing, capital management,signalling) or non-discretionary (related to the...
