Several factors – such as globalisation, digitisation, the increased role of intangible assets and sunk costs, as well as M&A activity and the (under)enforcement of merger control– have been...

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 ...

Signals Sell: Product Lines when Consumers Differ Both in Taste for Quality and Image Concern

This paper analyzes optimal product lines when consumers differ both in their taste for, quality and in their desire for social image. The market outcome features partial pooling and, product differentiation that is not driven by heterogeneous valuations for quality but by image, concerns. A typical monopoly outcome is a two-tier product line resembling a “masstige”, strategy as observed in luxury ...

The Effect of Retail Mergers on Prices and Variety: An Ex-post Evaluation

Unlike most retrospective merger studies that only focus on price effects, we also estimate the impact of a merger on product variety. We use an original dataset on Dutch supermarkets to assess the effect of a merger that was conditionally approved by the Dutch Competition Authority (ACM) on prices and the depth of assortment. We find that the merger did not affect prices but it led the merging parties ...
