This article examines the stochastic properties of US term spreads with parametric and semi-parametric fractional integration techniques. Since the observed data (rather than the estimated residuals from a cointegrating regression) are used for the analysis, standard methods can be applied. The...

By estimating a staggered price model over the period 1980Q1 to 2010Q2, this article documents that, after the euro changeover, Italian retailers have increased the number of price adjustments, which has translated into a higher inflation rate, with a detrimental effect on the competitiveness of...

This article examines the process of price discovery in the Mercato Telematico dei Titoli di Stato (MTS) system, which builds on the parallel quoting of euro-denominated government securities on a number of (relatively large) domestic markets and on a (relatively small) European marketplace...

This article analyses multiple cyclical structures in financial time series. In particular, we focus on the monthly structure of the Nasdaq, the Dow-Jones and the S&P stock market indices. The three series are modelled as long-memory processes with poles in the spectrum at multiple frequencies,...

In this note the empirical evidence presented by Karfakis and Moschos (1990) and Katsimbris and Miller (1993) on interest rate linkages in the EMS is reinterpreted and their finding of non-stationarity of interest rate differentials in the EMS is rationalized. It is argued that their results are...

This paper examines the relationship between unemployment, real oil price and real interest rates in Canada. Instead of following the classical approach based on I(0) stationarity or I(1) cointegrating relationships, fractional integration/cointegration techniques are used which allow for the...

This article estimates a fractional integration model with nonlinear deterministic trends for the inflation rates of five African countries. The results indicate that nonlinearities are present in the case of Angola and Lesotho, but not in the case of Botswana, Namibia and South Africa....

This study shows that the monthly structure of the US money stock can be specified in terms of a long-memory process, with roots at both the zero and the seasonal monthly frequencies. It uses a procedure that enables one to test simultaneously for the roots at all these frequencies. The results...

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...
