Workshop
Based on various data sources, the workshop will examine the economic and psychological situation of the self-employed three years after the onset of the COVID-19 crisis. Next to analyzing the immediate impact of the crisis, the workshop will address the adjustment measures taken by the self-employed and the long-term consequences. Possible research questions include what strategies the self...

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...

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...

How does online advertising affect consumer behaviour, product pricing and competition? To analyse this, I develop a theory of digital markets where an intermediary provides a platform for firms to advertise their product and where consumers need to engage in costly search if they want to learn about the product characteristics. First, I show that when prices are observable...

Using data on 4.1 million apps at the Google Play Store from 2016 to 2019, we document that GDPR induced the exit of about a third of available apps; and in the quarters following implementation, entry of new apps fell by half. We estimate a structural model of demand and entry in the app market. Comparing long-run equilibria with and without GDPR, we find that GDPR reduces consumer surplus and...

In response to strong revenue and income losses that a large share of the self-employed faced during the COVID-19 pandemic, the German federal government introduced a €50bn emergency aid program. Based on real-time online-survey data comprising more than 20,000 observations, we analyze the impact of this program on the subjective survival probability. In particular, we investigate how the digitalization ...

We study the impact of broadband availability on firms’ total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over the sample period, broadband availability, measured by 16 Mbps transmission rates, more than doubled in German ...
