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...

The Role of Physician-Patient Similarity in Diagnosis and Treatment Decisions: Evidence from Antibiotic Prescribing

This paper sheds light on the effectiveness of a specific type of incentive in this context: a monetary incentive that is paid conditionally upon panel ...

The Productivity Shock in Business Services

Sanctions against Russian Oligarchs also Affect Their Companies

The goal was to exert pressure on the Kremlin: initially to stop deploying troops to the Donetsk and Luhansk regions and ultimately to end its attack on Ukraine. The present report investigates how these sanctions affect companies headed by Russian oligarchs. The empirical findings show that after sanctions ...
