Economic theory provides ambiguous and conflicting predictions about the association between algorithmic pricing and competition. In this paper we provide the first empirical analysis of this relationship. We study Germany's retail gasoline market where algorithmic-pricing software became widely...

Fuel prices are commonly perceived to be excessively high, which regularly triggers political discussions about fuel price regulations. Consumers demand stricter fuel price regulations to provide transparency about the current price level and to protect them from sudden price fluctuations. Such...

We analyze spying out a rival’s price in a Bertrand market game with incomplete information. Spying transforms a simultaneous into a robust sequential moves game. We provide conditions for profitable espionage. The spied at firm may attempt to immunize against spying by delaying its pricing...

The unprecedented access of firms to consumer level data not only facilitates more precisely targeted individual pricing but also alters firms' strategic incentives. We show that exclusive access to a list of consumers can provide incentives for a firm to endogenously assume the price leader's...

We empirically assess the impact of the EU roaming regulation on mobile operators’ average revenues per user (ARPU) and retail prices. Using a differences-in-difference approach, hedonic price regressions and detailed operator and plan-level data we find that the regulation decreased mobile...

We provide a new framework to identify demand elasticities in markets where managers rely on algorithmic recommendations for price setting, and apply it to a dataset containing bookings for a sample of mid-sized hotels in Europe. Using non-binding algorithmic price recommendations and observed...

The roam-like-at-home regulation (RLAH) eliminated all mobile roaming surcharges to Eu-ropean consumers travelling within the European Economic Area (EEA). We measure the causal impact of the regulation on EEA roaming traffic, using the Rest of the World as a control group. We find large and...
