The novelty/value added of this paper is the comparison of the Epps effect between developed and emerging stock markets from Central Europe by means of the correction formula derived by the authors. The main goal of the study is to test whether or not asynchrony in transaction times is a...

We demonstrate that the lowest possible price change (tick-size) has a large impact on the structure of financial return distributions. It induces a microstructure as well as possibly altering the tail behavior. On small return intervals, the tick-size can distort the calculation of...

We study covariance estimation when compelled to use evenly spaced data which have already been manipulated by previous-tick interpolation. We propose an un- biased covariance estimator, which is designed to correct for the two biases arising because of the interpolation: non-synchronous trading...

We present a method to compensate statistical errors in the calculation of correlations on asynchronous time series. The method is based on the assumption of an underlying time series. We set up a model and apply it to financial data to examine the decrease of calculated correlations towards...

This paper investigates the dynamics of the leverage effect over time, using high frequency data. By applying Realized Kernel techniques, a more precise estimate of Realized Correlation ¨C compared to standard subsampled estimators of Realized Correlation ¨C is derived. This new measure avoids...

We find compelling evidence that stock return autocorrelation is not spurious. Specifically, we find that partial price adjustment is an important source, and in some cases the main source, of the autocorrelation. In contrast to previous tests, our tests of partial price adjustment are direct,...
