The asymmetry in the tail dependence between U.S. equity portfolios and the aggregate U.S. market is a well-established property. Given the limited number of observations in the tails of a joint distribution, standard non-parametric measures of tail dependence have poor finite-sample properties...

The multiple testing problem plagues many important issues in finance such as fund and factor selection. Many look good purely by luck. There are a number of statistical techniques to control for multiplicity that reduce Type I errors - but it is unknown by how much. We propose a new way to...

We propose a frequency-specific framework to link the common features in the multivariate high-frequency price jumps with the low-frequency exogenous factors. We introduce the measures of commonality and multiplicity based on high-frequency data and define the notions of co-arrivals and co-jumps...

Since the early 2000s, global liquidity has experienced very strong growth. Emerging Markets (EMs) have accumulated large foreign exchange reserves while developed markets have dramatically eased their monetary policies. Global excess liquidity has resulted in an increase in the size of...

We propose a modified mutual information measure to capture general asymmetric dependence between two random variables. Based on this measure, we propose a test of asymmetric dependence and examine its finite-sample performance. We show that our test has better power than competing tests with...

This paper examines the present value framework that links market capitalization to non-dividend cash flows (i.e., share repurchases and issuances) beyond the conventional price–dividend relationship. We show that total (dividend plus non-dividend) cash flows can account for a large fraction...

Large-scale inference has become increasingly popular in financial economics. I explore an empirical Bayes approach to large-scale multiple testing. The proposed approach bases its inference on the posterior probability that the null is true given the observed data. It provides a convenient way...
