Riesgo sistemático y titulización. Metodología de estudio de eventos para el caso español

This paper examines the systematic risk in those banks that participate as issuers in securitization transactions in the Spanish market from 1993 to 2010. Using an event study methodology and allowing systematic risk to change gradually within the event window, this paper provides empirical evidence that securitization has a positive impact on the systematic risk of Spanish banks in the days following and preceding the registration and issue dates, and increases the diversification of the portfolio of the bank. The empirical results presented in this paper show important informative implications for the different agents related to banks.
