In this paper I analyze a broad class of continuous-time jump diffusion models of asset returns. In the models, stochastic volatility can arise either from a diffusion part, or a jump part, or both. The jump component includes either compound Poisson or Lévy alpha-stable jumps. To be able to...

Restrictions on the ownership structure of a public company may harm the company's performance by preventing owners from choosing the best structure. We examine the stock-price performance and ownership structure, before and after the expiration of anti-takeover regulations, of a sample of...

We estimate the cross-sectional relationship between open market repurchases and accounting data for a large sample of dividend- paying and non-dividend paying firms over a twelve year period (1984-95). Consistent with the hypothesis that firms use open market repurchases to reduce the agency...
