Measuring mutual fund managers' skills by Microsoft's TrueSkill algorithm, we find highly skilled managers to behave self-confident resulting in higher risk-taking in the second half of the year compared to less skilled managers. Introducing the TrueSkill algorithm, which is widely used in the...

We analyze the quality of Bitcoin volatility forecasting of GARCH-type models applying different volatility proxies and loss functions. We construct model confidence sets and find them to be systematically smaller for asymmetric loss functions and a jump robust proxy

We study the efficiency of cryptocurrencies by measuring the price's reaction time to unexpected relevant information. We find the average price delay to significantly decrease during the last three years. For the cross-section of 75 cryptocurrencies we find delays to be highly correlated with...

The introduction of futures on Bitcoin eases the access of institutional investors to the market and offers an efficient way to short the cryptocurrency. We investigate the effect of this event on the market's price efficiency and find the Bitcoin market to turn efficient. We conduct commonly...

We show that investors acquire more public information about firms to which they are more socially proximate. On average, a standard deviation increase in the Social Connectedness Index (Bailey et al., 2018) between a firm's headquarter county and a searcher county is associated with 30% more...

We show that productivity at both the firm and employee (i.e., analyst and inventor) level temporarily declines upon announcements of takeover rumors that do not materialize. Such speculative news may hurt productivity because uncertainty and threat of job loss cause anxiety, distraction, and...

We present a new approach to test empirically the financial distress costs theory of corporate hedging. We estimate the ex-ante expected financial distress costs, which serve as a starting point to construct further explanatory variables in an equilibrium setting, as a fraction of the value of...

We propose a simple measure of investor sophistication based on financial statement experience derived from publicly available EDGAR log data about accounting information acquisition activity. This approach allows us to provide unique empirical evidence for the existence of attention induced...

We analyze the interaction between high workload of the Securities and Exchange Commission (SEC) staff and the information production stimulated by their review process of initial public offerings (IPOs). We find that high workload is associated with more generic comments in the first letter,...
