This paper presents a model of exchange rate determination in which the forward premium anomaly emerges as the result of unanticipated central bank interventions in the foreign exchange market. Deviations from uncovered interest parity (UIP) therefore represent neither unexploited profit...

Researchers have encountered difficulties in finding empirical evidence of Purchasing Power Parity (PPP) especially when conventional linear unit root tests are employed for the Japanese yen real exchange rate. Chortareas and Kapetanios (2004), however, report strong evidence in favor of a...

This paper revisits the empirical evidence of purchasing power parity under the current float by recursive mean adjustment (RMA) proposed by So and Shin (1999). We first report superior power of the RMA-based unit root test in finite samples relative to the conventional augmented Dickey-Fuller...

Standard unit-root tests are known to be biased towards the non-rejection of a unit-root when they are applied to time series with non-linear dynamics. Unfortunately, not much is known about the source of the power loss mainly because the analysis on nonstationarity and nonlinearity to this date...

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...

Taylor (2002) claims that Purchasing Power Parity (PPP) has held over the 20th century based on strong evidence of stationarity for century-long real exchange rates for 20 countries. Lopez et al. (2005), however, found much weaker evidence of PPP with alternative lag selection methods. We...

Recent empirical work has shown the importance of nonlinear adjustment in the dynamics of real exchange rates and real interest differentials. This work suggests that the tenuous empirical linkage between the real exchange rate and the real interest differential might be strengthened by...

This study investigates to what extent can an exchange rate model built on uncovered interest parity (UIP) match the empirical features of the exchange rate and the interest differential data. This article presents a continuous-time model of UIP in which the interest differential evolves...

This paper revisits the empirical evidence of purchasing power parity under the current float by recursive mean adjustment (RMA) proposed by So and Shin (1999). We first report superior power of the RMA-based unit root test in finite samples relative to the conventional augmented Dickey–Fuller...
