Net Neutrality and CDN Intermediation

We analyze competition between Internet Service Providers (ISPs) where consumers demand heterogeneous content within two Quality-of-Service (QoS) regimes, Net Neutrality and Paid Prioritization, and show that paid prioritization increases the static efficiency compared to a neutral network. We also consider paid prioritization intermediated by Content Delivery Networks (CDNs). While the use of CDNs ...

Antibiotic Prescribing and Diagnostic Testing: Physician Behavior in the Case of Urinary Tract Infection

Abstract: When a patient with symptoms of urinary tract infection arrives at a physician's office, it needs to decide which antibiotic drug to prescribe.

Physicians can conduct antibiotic susceptibility tests in order to create current resistance profiles...

The Effect of a Leniency Rule on Cartel Formation and Stability: Experiments with Open Communication

Cartels can severely harm social welfare. Competition authorities introduced leniency rules to destabilize existing cartels and hinder the formation of new ones. Empirically, it is difficult to judge the success of these measures because functioning cartels are unobservable. Existing experimental studies confirm that a leniency rule indeed reduces cartelization. We extend these studies by having a ...

Data Network Effects: The Example of Internet Search

Abstract:   The rise of dominant firms in data driven industries is often credited to their alleged data advantage. Empirical evidence lending support to this conjecture is lacking.

We study the search result quality for search keywords on...

Partitioned Pricing and Consumer Welfare

Abstract:   In online commerce, obfuscation strategies by sellers are hypothesized to mislead consumers to their detriment and to the profit of sellers. One such obfuscation strategy is partitioned pricing in which the price is split into a base price and add-on fees. While empirical evidence suggests that partitioned pricing impacts consumer decisions through salience effects, its consumer...

Modeling Geographical Preferences to Study the Welfare Implication of Airbnb's Presence in the Short-Term Accomodation Market

Abstract:  We study competition between Airbnb and hotel accommodations in Paris in 2017 to assess the welfare implications of Airbnb’s presence on hotels and travelers. The existing literature on the subject exclusively uses across city variation in Airbnb diffusion. Consequently, it does not take into account that the location of an accommodation within a city might be an important...
