Standard empirical investigations of jump dynamics in returns and volatility are fairly complicated due to the presence of latent continuous-time factors. We present a new discrete-time framework that combines heteroskedastic processes with rich specifications of jumps in returns and volatility....

An empirical study of the Dow Jones Stoxx Football index exhibits a high volatility of the returns and share prices regarding a sample of floated clubs as well as an insufficient market depth (low and irregular traded volumes). The theoretical analysis of the relationship between market...
