Efficiency and instabilities of financial markets

Abstract

In the first part I will show how market informational efficiency can be successfully studied on high frequency financial data, finding analytical results on ARMA processes and using a more empirical approach. In the second part I will show the main self- and cross-exciting features of market instabilities and how they can be effectively described with original models based on Hawkes processes.
