    Competition and Mergers with Strategic Data Intermediaries

    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...

    SOEP 2022 - 14th International German Socio-Economic Panel User Conference

    The 14th International German Socio-Economic Panel User Conference (SOEP2022) will be held in Berlin from June 30 to July 1, 2022 at DIW Berlin. The conference provides researchers who use the SOEP (including the SOEP part of the Cross-National Equivalent File (CNEF) and LIS/LWS data) with the opportunity to present and discuss their work with their peers. Researchers of all disciplines (e.g.,...

    Sponsored Search: How Platforms Exacerbate Product Market Concentration

    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...

    GDPR and the Lost Generation of Innovative Apps

    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...

    Assessing the Value of Data for Prediction Policies: The Case of Antibiotic Prescribing

    We quantify the value of data for the prediction policy problem of reducing antibiotic prescribing to curb antibiotic resistance. Using varying combinations of administrative data, we evaluate machine learning predictions for diagnosing bacterial urinary tract infections and the outcomes of prescription rules based on these predictions. Simple patient demographics improve prediction quality substantially ...

    Facebook Shadow Profiles

    Data is often at the core of digital products and services, especially when related to online advertising. This has made data protection and privacy a major policy concern. When surfing the web, consumers leave digital traces that can be used to build user profiles and infer preferences. We quantify the extent to which Facebook can track web behavior outside of their own platform. The network of engagement ...

    Renewable Energy Targets and Unintended Storage Cycling: Implications for Energy Modeling

    To decarbonize the economy, many governments have set targets for the use of renewable energy sources. These are often formulated as relative shares of electricity demand or supply. Implementing respective constraints in energy models is a surprisingly delicate issue. They may cause a modeling artifact of excessive electricity storage use. We introduce this phenomenon as “unintended storage cycling”, ...

    Measurement Equivalence in Probability and Nonprobability Online Panels

    Nonprobability online panels are commonly used in the social sciences as a fast and inexpensive way of collecting data in contrast to more expensive probability-based panels. Given their ubiquitous use in social science research, a great deal of research is being undertaken to assess the properties of nonprobability panels relative to probability ones. Much of this research focuses on selection bias, ...
