Empirical essays on banking contagion in Europe: an analysis in terms of stock prices.

Summary The objective of this thesis is to contribute to the debate on banking regulation within the EU. Indeed, we have first recalled the situation of the European banking industry today and have imagined a model of supranational regulation. We then showed that the growing interdependence between European banks can be a source of contagion risk both at the domestic and cross-border levels. An analysis of the determinants of this contagion showed that it is best explained by financial indicators when it is cross-border��re and by accounting indicators when it is domestic. The impact of both domestic and cross-border bank consolidations remains negligible on the systematic risk of the banks selected in our sample.
