This study is also the first work on this topic that conducts tests on the basis of a (serial correlation consistent) Difference-in-Difference model with level and trends. As a robustness check, we use the "ignoring time series information" model in a form that is modified for nonsynchronous interventions. We were not able to identify income or employment effects of the construction of new stadiums for the FIFA World Cup 2006, which are significantly different from zero.
