Shopping hours and entry: An empirical anlysis of Aldi's opening hours

Aldi, the biggest discounter in Germany, started to systematically extend shopping hours of its stores in 2016. We interpret the decision to extend opening hours of a specific Aldi store as entry into a new market. By using a novel data set containing the opening hours of nearly all German grocery retailers, we find that consumer and firm learning influence that decision. The presence of a nearby Aldi already opened longer increases the probability that a given Aldi extends its opening hours. However, if a nearby competitors store is short opened, the probability that Aldi extends opening hours decreases.
