This is an online seminar using Webex. You will receive the login data with the invitation to the talk. Abstract:   Cities worldwide have regulated the peer-to-peer short-term rental market claiming that those markets remove apartments from the long-term housing market, causing an increase in rents. However, at the time many of these policies were passed, empirical evidence for or...

Modeling Geographical Preferences to Study the Welfare Implication of Airbnb's Presence in the Short-Term Accomodation Market

Abstract:  We study competition between Airbnb and hotel accommodations in Paris in 2017 to assess the welfare implications of Airbnb’s presence on hotels and travelers. The existing literature on the subject exclusively uses across city variation in Airbnb diffusion. Consequently, it does not take into account that the location of an accommodation within a city might be an important...

Market Concentration in Europe: Evidence based on Antitrust Markets (cancelled)

Abstract:  An increasing body of empirical evidence has documented trends to risen concentration, profits, markups, and market power in many industries across the world since the 1980s. Several factors – such as globalisation, digitisation, the increased role of intangible assets and sunk costs, as well as M&A activity and the (under)enforcement of merger control– have been...

Battling Antibiotic Resistance: Can Machine Learning Improve Prescribing?

Abstract:  Antibiotic misuse due to prescribing under diagnostic uncertainty is a leading driver of antibiotic resistance. We investigate the magnitude and mechanisms by which machine learning predictions can enable policies that reduce antibiotic misuse. Building on predictions from administrative data on urinary tract infections in Denmark, we evaluate counterfactual policies that replace...

Learning from Data and Network Effects: The Example of Internet Search

The rise of dominant firms in data driven industries is often credited to their alleged data advantage. Empirical evidence lending support to this conjecture is surprisingly scarce. In this paper we document that data as an input into machine learning tasks display features that support the claim of data being a source of market power. We study how data on keywords improve the search result quality ...

Airbnb and Rents: Evidence from Berlin

Cities worldwide have regulated peer-to-peer short-term rental platforms claiming that those platforms remove apartments from the long-term housing market, causing an in- crease in rents. Establishing and quantifying such a causal link is, however, challenging. We investigate two policy changes in Berlin to first assess how effective they were in regulating Airbnb, the largest online peer-to-peer short-term ...

Partitioned Pricing and Consumer Welfare

In online commerce, obfuscation strategies by sellers are hypothesized to mislead consumers to their detriment and to the profit of sellers. One such obfuscation strategy is partitioned pricing in which the price is split into a base price and add-on fees. While empirical evidence suggests that partitioned pricing affects consumer decisions through salience effects, its consumer welfare consequences ...
