This paper investigates the relationship between market liquidity and bank-dominated corporate governance structure of Japanese listed firms, represented as main bank relationships and cross shareholdings. Using the data of bank-dominated corporate governance mechanisms like Japan, we...

This paper proposes new test statistics for the dependence and cross and auto covariance estimators of bivariate noise processes. It derives their asymptotic distributions and provides additional tests for the statistical significance of covariance estimators. Monte Carlo simulation shows that...

This paper examines the relation between pre-trade transparency and market quality in the Tokyo Stock Exchange (TSE). Mixed evidence related to this relation has been reported worldwide. We analyze this relation using evidence from a change in the TSE disclosure policy in the 2000s. We find a...

This paper examines effects of realized covariance matrix estimators based on high-frequency data on large-scale minimum-variance equity portfolio optimization. The main results are: (i) the realized covariance matrix estimators yield a lower standard deviation of large-scale portfolio returns...

This paper investigates the relationship between market liquidity and bank-dominated corporate governance structure of Japanese listed firms, represented as main bank relationships and cross shareholdings. We find that (i) main bank lending relationships increase market liquidity and reduce...

The cumulative covariance estimator in Hayashi and Yoshida (2005b) which suits for non-synchronous observations possibly has a bias in the presence of the observational noise. We propose the test statistic to detect whether the observational noise causes a measurable bias in the estimator of...

There are many approaches for estimating an integrated variance and covariance in the presence of market microstructure noise. It is important to know a dependence of noise to construct the integrated variance and covariance estimators. We study a time dependence of bivariate noise processes in...

This paper presents an examination of the relation between pre-trade transparency and market quality in the Tokyo Stock Exchange (TSE). Mixed evidence related to this relation has been reported worldwide. We analyzed this relation using a discrete change of disclosure policy in the 2000s. A...
