Diskussionspapiere 1930 / 2021
An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level while firm level revenues are a poor indicator of product sales. We use a novel database that identifies over ...

Diskussionspapiere 1931 / 2021
We provide an evaluation of the impact of German public subsidy schemes in municipalities of Bavaria and Lower Saxony aimed at supporting the deployment of basic broadband infrastructure in rural Germany. Such subsidies are subject to state aid control by the European Commission and may only be granted if the potential market failure is addressed without distorting competition. We first analyse the ...

Diskussionspapiere 1987 / 2021
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. This raised concerns that GAFAM acquisitions target potential competitors yet fly under the radar of current merger control due to the features of the digital economy. We empirically study the competitive effects ...

The European Commission is facing the challenge and opportunity of implementing the Green Deal while simultaneously initiating the recovery of the economy following the coronavirus crisis. Investments in the basic materials industry’s transition to climate neutrality play a central role in this, as the sector is responsible for 16 percent of the EU’s CO2 emissions and is key to downstream value chains. ...

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 ...

Carbon Capture and Storage (CCS) might be a central technology to reach the decarbonisation goals of the European energy system. However, CCS deployment faces multiple economic, technological, and infrastructure challenges. Related literature tends to only focus on certain aspects of the CCS technology or to be limited to a particular sector perspective. In contrast, this paper presents a holistic ...
