A popular argument in policy discussions on the liberalisation of business hours proceeds on the assumption that business
hours are strategic complements: if some firms open longer hours, competitors will be forced to extend their opening hours
too. We provide first empirical evidence on the impact of competition and the form of strategic interaction in business hours
between firms by using detailed information on business hours as well as the location of retail gasoline stations in Austria.
Our findings reject the presumption of business hours being strategic complements. Firms tend to have longer opening hours
in a more competitive environment.
