We estimate a standard principal agent model with constant relative risk aversion and lognormal stock prices for a sample of 598 US CEOs. The model is widely used in the compensation literature, but it predicts that almost all of the CEOs in our sample should hold no stock options. Instead, CEOs...

In this paper we investigate how the enactment and enforcement of insider trading restrictions affect the way in which information about acquisitions is released before the actual acquisition announcement. We analyze a sample with almost 19,000 acquisition announcements from 48 countries. We...
