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. A drug's efficacy in treating the infection depends on the individual, time-dependent resistance profile of the bacterium causing the infection. Physicians can conduct antibiotic susceptibility tests in order to create current resistance profiles...

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. In this paper, we show that data as an input into machine learning tasks displays features that favor the hypothesis that data is a source of market power. 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...

Netzneutralität: Priorisierungen sind aus ökonomischer Sicht sinnvoll

Das Prinzip der Netzneutralität wurde im November 2015 von der Europäischen Union als Verordnung zur Gleichbehandlung aller Datenpakete im Netz verabschiedet. Betrachtet man die Netzneutralität nach rein ökonomischen Gesichtspunkten, zeigt sich, dass die generelle Möglichkeit zur Priorisierung von Datenpaketen jedoch durchaus sinnvoll sein kann, da sie zu einer effizienteren Nutzung der bestehenden ...

Net Neutrality: Prioritization Is Beneficial from an Economic Perspective

The principle of net neutrality was adopted by the European Union as a regulation promoting equality among all data packets in the Internet. Considering net neutrality from a purely economic viewpoint, however, the general possibility to prioritize data packets would likely lead to a more efficient use of existing network capacity. This is particularly applicable given the growth in data traffic and ...

EU Roaming Regulation: Theoretical Model Suggests a Positive Assessment

Since June 15, 2017, mobile network operators in the European Economic Area may not impose surcharges for making telephone calls, sending text messages, or using data services in other EEA countries. The regulation was designed to create a digital domestic market without adversely affecting consumers. The regulation raises the expectation of changes in mobile network operators’ tariff structures. Theoretical ...
