We analyze mergers between strategic data intermediaries collecting consumer information that they sell to firms competing in a product market. We show that a merger: (a) reduces the intensity of competition in the product market through a change in the selling strategies of merging intermediaries; (b) increases data collection, reducing consumer surplus through a better rent extraction. We argue...
In the absence of globally coordinated action to combat climate change, governments are concerned that ambitious carbon pricing could harm the competitiveness of emission-intensive industries. A prominent measure to prevent that manufacturing producers relocate to countries with laxer environmental regulation are carbon border adjustments often referred to as carbon tariffs. Several studies have...
Advertising on e-commerce platforms, which enables third-party sellers to place their products as sponsored listings within organic results, is a widespread phenomenon, creating large revenues for online marketplaces. While economic theory suggests that advertising can serve as a signal for product quality, the empirical evidence is ambiguous. In this project, I collect data from a leading online...
This paper empirically analyses the impact of government ownership on competition. The COVID-19 pandemic and subsequent governmental equity interventions in the European airline industry provides for a particularly ideal setting to investigate this topic, and this for several reasons. First, airline markets and competition therein are well-defined and well-understood. Second, European countries...
The innovation impact of acquisitions of small targets with products close to launch by large product market incumbents is currently debated, weighing whether incumbents might preemptively terminate or “kill” the innovative projects of these targets. This paper provides empirical evidence on which M&A deals spur and which stifle innovation. To this end, we not only look at the product market...
We examine how competition affects VAT pass-through in isolated oligopolistic markets as defined by the Greek islands. Using daily gasoline prices and a difference-in-differences methodology, we study how changes in VAT rates are passed through to consumers in islands with different number of retailers. We show that pass-through increases with competition, going from 50% in monopoly to around 80%...
The self-employed faced strong income losses during the Covid-19 pandemic. Many governments introduced programs to financially support the self-employed during the pandemic, including Germany. The German Ministry for Economic Affairs announced a €50bn emergency-aid program in March 2020, offering one-off lump-sum payments of up to €15,000 to those facing substantial revenue declines. By reassuring ...
