Estimating Demand with Multi-Homing in Two-Sided Markets

We empirically investigate the relevance of multi-homing in two-sided markets. First, we build a micro-founded structural econometric model that encompasses demand for differentiated products and allows for multi-homing on both sides of the market. We then use an original dataset on the Italian daily newspaper market that includes information on double-homing by readers to estimate readers’ and advertisers’ ...

Common Ownership in the U.S. Pharmaceutical Industry: A Network Analysis

We investigate patterns in common ownership networks between firms that are active in the U.S. pharmaceutical industry for the period 2004–2014. Our main findings are that “brand firms”—that is, firms that have research and development capabilities and launch new drugs—exhibit relatively dense common ownership networks with each other that further increase significantly in density over time, whereas ...

A Retrospective Study of State Aid Control in the German Broadband Market

Competitors’ Reactions to Big Tech Acquisitions: Evidence from Mobile Apps

Since 2010, Google, Apple, Facebook, Amazon, and Microsoft (GAFAM) have acquired more than 400 companies. Competition authorities did not scrutinize most of these transactions and blocked none.

US and EU secure vaccine production on home soil

The deployment of a safe and effective vaccine for Covid-19 will be central to lifting containment measures. In a bid to speed up vaccine deployment, governments are entering into ‘Advance Purchase Agreements’ (APAs) with vaccine companies to secure access to vaccine doses. We document and compare the vaccine procurement strategies of the US and the EU. Most notably, we find that both...
