The objective of the Working Papers series is to disseminate original research studies on economics and finance, which since 2003 have been reviewed on an anonymous basis. Through their publication, the Banco de España hopes to contribute to the economic analysis and knowledge of the Spanish economy and its international context.
The opinions and analyses published in the Working Papers series are the responsibility of the authors and are not necessarily shared by the Banco de España or the Eurosystem.
