This paper evaluates the speed of convergence across national stock markets employing a nonlinear, nonparametric stochastic model of relative stock prices. We use operational algorithms for estimating general measures of persistence of the relative stock price that are based on two statistical...

Cheung et al. (2004) use a vector error correction model that allows different speeds of convergence for nominal exchange rates and relative prices toward PPP. With the current float monthly data for five countries, they argue that the sluggish PPP reversion is primarily driven by nominal...

We examine spillover effects of the recent U.S. financial crisis on five emerging Asian countries by estimating conditional correlations of financial asset returns across countries using multivariate GARCH models. We propose a novel approach that simultaneously estimates the conditional...

We reassess the degree of exchange rate co-movement between the Japanese yen and 5 emerging Asian currencies relative to the US dollar in the 2000s. It is often claimed that these currencies have been closely tied with the Japanese yen possibly due to active interactions of Japan and emerging...

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 estimates the degree of persistence of 16 long-horizon real exchange rates relative to the US dollar. We use nonparametric operational algorithms by El-Gamal and Ryu (2006) for general nonlinear models based on two statistical notions: the short memory in mean (SMM) and the short...

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...

In the Kehoe and Midrigan (2007) model, the persistence parameter of the real exchange rate is closely related to the measure of price stickiness in the Calvo-pricing model. When we employ this view, Rogoff's (1996) 3 to 5 year consensus half-life implies that firms update their prices every 18...

We estimate dynamic conditional correlations of financial asset returns across countries by an array of multivariate GARCH models and analyze spillover effects of the recent US financial crisis on 5 emerging Asian countries. We find a symptom of financial contagion around the collapse of Lehman...

This paper examines common forces driving the prices of 51 highly tradable commodities. We demonstrate that highly persistent movements of these prices are mostly due to the first common component, which is closely related to the US nominal exchange rate. In particular, our simple factor-based...
