    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...

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.

    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 ...

    Where Does the Fair Trade Money Go? How Much Consumers Pay Extra for Fair Trade Coffee and How This Value Is Split along the Value Chain

    Fair Trade certification aims at transferring wealth from the consumer to the farmer; however, coffee passes through many hands before reaching final consumers. Bringing together retail, wholesale, and stock market data, this study estimates how much more consumers are paying for Fair Trade-certified coffee in US supermarkets and finds estimates around $1.50 per lb. The study then assesses how this ...
