Abstract: Financial markets provide an ideal frame for the study of first-passage time events of non-Gaussian correlated dynamics mainly because large data sets are available. Tick-by-tick data of six...

This paper consists of two parts. In the first part, by building on the work of Jouini
and Kallal in [26], Sch¨urger in [37], Frittelli in [15], Pham and Touzi in [34] and Napp in [33], we prove the ...
We derive a mesoscopic description of the behavior of a simple financial market where the agents can create their own portfolio between two investment alternatives: a stock and a bond. The model is de...
