This paper studies the role of insider trading in explaining cross-country differences in stock market volatility. It introduces a new measure of insider trading. The central finding is that countries with more prevalent insider trading have more volatile stock markets, even after one controls...

We analyze a model of informed trading where an activist shareholder accumulates shares in an anonymous market and then expends costly effort to increase the firm value. We find that equilibrium prices are affected by the position accumulated by the activist, because the level of effort...

Specifically, the paper looks at a number of English securities that...

Does information asymmetry affect the cross-section of expected stock returns? We explore this question using representative portfolio holdings data from the Shanghai Stock Exchange. We show that institutional investors have a strong information advantage, and that past aggressiveness of...

Blockchain front-running involves multiple agents, other than the legitimate agent, claiming a payment from performing a contract. It arises because of the public nature of blockchain transactions and potential network congestion. This paper notes that disputes over payments are similar to...

Hedge fund managers contribute substantial personal capital, or "skin in the game," into their funds. While these allocations may better align incentives, managers may also strategically allocate their private capital in ways that negatively affect investors. We find that funds with more inside...

Using a simple empirical strategy, we decode the information in insider trades. Exploiting the fact that insiders trade for a variety of reasons, we show that there is predictable, identifiable "routine" insider trading that is not informative for the future of firms. Stripping away these...

This research approach, which we term insider econometrics, addresses these questions by combining insights from industry insiders with rigorous econometric tests about the adoption and productivity effects of new management practices using rich industry-specific data. Understanding the...
