The classical realized variance (RV) estimator is biased due to microstructure effects and asset price jumps. Robust realized variance (RRV) estimators adjust for these biases, and make more efficient of use of the intraday data. This article examines the benefits of using RRV estimators instead...

In this study, we use panel cointegration methods to investigate the relationship between stock prices and earnings-per-share (EPS). Furthermore, we consider whether stock prices respond to EPS under the different level of growth rate of operating revenue. The empirical result indicated that the...

The financial crisis of 2007-2009 has begun in July 2007 when a loss of confidence by investors in the value of securitized mortgages in the United States resulted in a liquidity crisis. World stock markets peaked in October 2007 and then entered a period of high volatility which culminated with...

What market (spot or future) reflects news first? This question is investigated with Granger causality and Breitung and Candelon (2006) causality test in the frequency domain for Brazilian stock market. The results differ depending on which index (ETF, exchange traded funds, or the spot index)...

Several panel unit root tests based on different ways to account for cross-unit dependence are reviewed. The note then illustrates the tests by checking whether the martingale difference hypothesis is appropriate for stock prices on the German stock market: according to the martingale difference...

This note studies the long-run relationship between real estate and stock markets in the Taiwan context over the 1986Q3 to 2006Q4 period, using standard cointegration test of Johansen and Juselius (1990) and that of Engle-Granger (1987) as well as the fractional cointegration test of Geweke and...

In this study, we revisit the issue as to the presence of Rational Bubbles in the Korea stock market during the May 1996 to November 2007 period using three cointegration tests, namely JJ (Johansen and Juselius, 1990), KSS (Kapetanois et al., 2006) and BN (Bierens, 1997, 2004) approaches. The...

This investigation adopts the Correlated Bivariate Poisson GARCH with Jump and Diffusion Volatility Spillover (CBP-GARCH-JDSV) model to determine whether the Qualified Foreign Institutional Investors (QFIIs) deregulation in Taiwanese stock markets influences normal and abnormal information...

This work proposes the application of a stochastic volatility model with jumps to the BRL/USD exchange rate. This model decomposes the process into transitory and permanent components that capture the jumps in the level of the unobserved volatility process. The model estimation is done using...
