T Aalberg, AT Jenssen - Scandinavian Political Studies, 2007 - Wiley Online Library

… Based on a quasi-experimental design prior to the 2001 Norwegian parliamentary election, this study finds that the outcome of the television debates does matter. Winning a debate can actually make a difference, and significant changes in issue ownership...
