This article introduces dynamic models for the spot foreign exchange rate with capturing both the rare events and the time-inhomogeneity in the fluctuating currency market. For the rare events, we use a compound Poisson process with log-normal jump amplitude to describe the jumps. As for the...

In this article, we study the pattern as well as the systematic features of the calendar effect perceived in the intraday volatility of the foreign exchange rate of the euro vis-à-vis the dollar at five minutes of intervals. We obtain by the means of this analysis a differentiation of these...

In this article, we examine the announcement effect of news relating to the monetary policies of the ECB and the FED and resulting from the official meetings of the Council of the governors and the FOMC on intraday volatility of the foreign exchange rate euro-dollar at five minutes of intervals....

We investigate the role of jumps in transmitting volatility between foreign exchange markets (Engle, Ito, and Lin, 1990; Melvin and Peiers Melvin, 2003; Cai, Howorka, and Wongswan, 2008). We show that recently developed estimators have very different implications for the impact of jumps on exchange rate...

The main focus of this paper is to measure the speed of adjustment of the exchange rate by means of the persistent profile approach developed by Pesaran and Shin (1996) to examine the symmetry and proportionality assumptions of the purchasing power parity (PPP) theory of exchange rates for the...

This paper deals with statistics�and econometrics�properties of fractionally integra- ted GARCH (FIGARCH). We compare these characteristics with those of traditional models. We insist on the GARCH exponential/IGARCH in�nite decrease of volatility impact. Then, we apply it on three Tunisian...

In this book several econometrics techniques are used to perform quantitative research of the exchange rate in transition. This is an empirical work based on related economic theory. While the stress is put on the exchange rate of the Czech koruna, the subject is analyzed from a broader...

This paper proposes to model the error term in smooth transition autoregressive target zone model as Gaussian with stochastic volatility (STARTZ-SV) or as Student-t with GARCH volatility (STARTZ-TGARCH). Using the dynamics of Norwegian krone exchange rate index, we show that both models produce...

The paper presents estimates of devaluation expectations for six EMS currencies relative to the Deutschmark, for the period March 1979 - May 1990. The estimation method is simple and operational, and consistently generates sensible results. The estimates are constructed by adjusting interest...

Stylized empirical facts on the behaviour of exchange rates and interest rate differentials in target zone arrangements are at odds with the predictions of the simple (fully credible) target zone model. Incorporating time-varying devaluation risk in target zone models enriches the...
