In this paper, we summarize the economic literature on non-price effects of mergers and acquisitions (M&As). Specifically, we discuss the effects of M&As on innovation, product variety, and sustainability. Although the relationship is theoretically ambiguous, the vast majority of ex-post...

We examine how different pass-through rates, from input- to final consumer prices, and different vertical contracts affect upstream market definition. Our theory model predicts that, under reasonable conditions, higher pass-through rates lead to definitions of larger upstream markets. Data...

Over the last years, several reports highlighted the market power of very large online platforms that are gatekeeping intermediaries between businesses and consumers, and the difficulty for classic competition policy tools to deal effectively with anti-competitive practices in these platforms....

This paper analyses the interdependency between the market for music recordings and concert tickets, assuming that there are positive indirect network effects both from the record market to ticket sales for live performances and vice versa. Using a model with two interrelated Salop circles we...

This paper studies competition in the German market for mobile telecommunications, motivated by recent suggestions that T-Mobile and Vodafone possess a position of collective dominance. Allegedly, their position of joint dominance is secured through a combination of first-mover advantages and...

This paper estimates demand elasticities for the Turkish mobile telecommunication market. In contrast to most other studies, firm level data is used to estimate dynamic panel data models including instrumental variable techniques. Both short- and long-run elasticities are calculated, yielding a...
