The results of this paper complement the recent findings of real exchange rates as stationary processes. The standard procedure of applying a battery of unit root tests can be problematic since the tests are sensitive to the specifics of the time-series process. The novelty of the approach we...

Global current account imbalances have been one of the focal points of interest for policymakers during the last few years. Less attention has been paid, however, to the diverging current account balances of the individual euro area countries. In this paper we consider the dynamics of current...

The present paper tests for the validity of long-run purchasing power parity (PPP) for the three key currencies of the recent floating exchange rate period, the US dollar, the German mark and the Japanese yen. The novelty of the paper is that the validity of the PPP conditions relating the...

The purpose of the paper is twofold. Firstly, we test the validity of the PPP hypothesis for selected CEEC (Czech Republic, Hungary, Poland and Slovak Republic). Secondly, we attempt to define those countries’ trade linkages between Euro Area, US and the rest of the world. By applying...

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...

In this paper we introduce the STAR-STGARCH model that can characterize nonlinear behaviour both in the conditional mean and the conditional variance. A modelling cycle for this family of models, consisting of specification, estimation, and evaluation stages is constructed. Misspecification...

It is well documented that macroeconomic fundamentals are little help in predicting changes in nominal exchange rates compared to the predictions made by a simple random walk. Lettau and Ludvigson (2001) find that fluctuations in the common long-term trend in consumption, asset wealth, and labor...

We examine the Purchasing Power Parity (PPP) hypothesis using a unique panel of monthly data on black market exchange rates for twenty emerging market economies over the period 19973M1-1993M12. We apply a large number of recent heterogeneous panel unit root and cointegration tests. Panel unit...

This paper builds on Kočenda (2001) and extends it in two ways. First, two new intervals of the proximity parameter ε (over which the correlation integral is calculated) are specified. For these ε- ranges new critical values for various lengths of the data sets are introduced and through...

The ECB recommends to prospective euro-area members that they choose the central parities, for fixing their currencies against the euro, consistent with a broad range of economic indicators while taking account of the market rate as well. In this paper, we estimate a behavioral model of the real...
