This paper develops a dynamic portfolio selection model incorporating economic uncertainty for business cycles. It is assumed that the financial market at each point in time is defined by a hidden Markov model, which is characterized by the overall equity market returns and volatility. The risk...

The presence of transaction costs in trading implies a non-linear adjustment process of real exchange rates towards Purchasing Power Parity (PPP). This may make the traditional tests for PPP using a linear framework, which generally tend to refute the PPP hypothesis, unreliable. This study...

The goal of this paper is to disentangle the respective contributions of the nominal exchange rate and the price differential to the adjustment towards the Purchasing Power Parity relation. To this end, we estimate a threshold vector equilibrium correction model, whose dynamics is consistent...

Using an improved statistical methodology including tests designed for heterogeneous panels, this paper tests for mean reversion in monthly US Dollar based real exchange rates for nine East Asian countries, including those that were severely affected by the 1997 Asian financial crises. The...

This study shows that augmented Dickey-Fuller (ADF) test failed to detect covariance nonstationary series. Supportive of Ahamada (2004), this study finds that the cumulative sums of squares procedure in Inclán and Tiao (1994) is useful to complement the ADF test. As illustration, the ADF test...

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...

This paper utilises various recently developed econometric methods to obtain better approximations to the half-life for real exchange rates of ten South African Development Community (SADC) countries and to generate confidence intervals for half-life deviations from the purchasing power parity...

This paper revisits the empirical evidence of purchasing power parity under the current float by the recursive mean adjustment (RMA) method (So and Shin, 1999). We first demonstrate superior finite sample performance of the RMA-based unit root test over the augmented Dickey-Fuller test via Monte...

The paper analyzes the impact that certain administrative measures of monetary authorities have on exchange rates. Using the Perron test, the authors test for the existence of structural change in the development of exchange rates in Central and Eastern European countries. The dates when...
