This paper examines the linkage of real interest rates of a group of Pacific-Basin countries with a focus on East Asia. We consider monthly real interest rates of the US, Japan, Korea, Singapore, and Thailand from 1980 to 2004. The impulse response analysis and half-life estimation are conducted...

This study examines return predictability of major foreign exchange rates by testing for martingale difference hypothesis (MDH) using daily and weekly nominal exchange rates from 1975 to 2009. We use three alternative tests for the MDH, which include the wild bootstrap automatic variance ratio...

A Monte Carlo experiment is conducted to compare power properties of alternative tests for the martingale difference hypothesis. Overall, we find that the wild bootstrap automatic variance ratio test shows the highest power against linear dependence; while the generalized spectral test performs...

Financial market participants and policy-makers can benefit from a better understanding of how shocks can affect volatility over time. This study assesses the impact of structural changes and outliers on volatility persistence of three crude oil markets - Brent, West Texas Intermediate (WTI) and...

We determine the events that cause large shocks in volatility of the DJIA index over the period 1928-2010, using intervention analysis and conditional heteroscedasticity model. We use a moving subsample window to take into account the periods with high or low volatility, allowing thus to...
