History has shown us the role that financial and banking crises have had in economic transformation. The last crisis in 2008 was particularly significant because of its extent and its effect worldwide. Two aspects hold equal importance. Firstly, governance is a key concept to be clearly defined and enforced, especially within the EU. Both entrepreneurial and financial players must measure the impact of their various actions (transparency in decision-making processes, strategic choices to achieve profit, etc.), maintaining their market position while preserving the social positioning of all partners. Secondly, from a more technical point of view, the relevance of mathematical and quantitative methods should be discussed in order to evaluate asset performance. Securitization has always been a tool used to increase financial institutions' profit margins but it cannot become their primary goal. The error does not come from the use of this technique but from its misuse at international level.This book aims to provide the reader with a broad discussion of the financial impacts and consequences arising from the last subprime crisis. By means of an international and European analysis, the different contributors intend to stress the relevance of a multi-national solution guaranteeing the stability of the international financial and banking system.
