In this article, we test the presence of financial contagion during the subprime mortgage crisis of 2007. For this purpose, we propose a new procedure for testing the non-linearity of the mechanisms of the shock distribution estimated through a model of long-term interdependence. We apply this...

The US financial crisis has underlined the fact that markets tend to be more dependent during the crisis than they are during the pre-crisis periods. This situation is usually referred to as contagion, a notion which has recently attracted the attention of several researchers working on finance...

We build a sequence of empirical measures on the space D(R_+,R^d) of R^d-valued c\`adl\`ag functions on R_+ in order to approximate the law of a stationary R^d-valued Markov and Feller process (X_t). We obtain some general results of convergence of this sequence. Then, we apply them to Brownian...
