Brown Bag Seminar Industrial Economics

We provide a description of ownership patterns in the top 25 European banks for the period 2003–2015, where we especially focus on the global financial crisis. Investment managers, such as Blackrock, are dominant in terms of number of block holdings in different banks, maintaining fairly stable “common ownership” networks throughout our sample. However, the financial crisis led ...

European firms, however, are different as top investors with large stakes, like governments, founding families and foundations are much more prevalent. This paper takes a well-known common ownership measure derived from ...

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 ...

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 ...

Abstract:  Trust is thought to be an important driver of economic growth and other economic outcomes. Previous studies suggest that trust may be a combination of risk attitudes, distributional preferences, betrayal aversion, and beliefs about the probability of being reciprocated. We compare the results of a binary trust game to the results of a series of control treatments that remove the ...

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 ...

Abstract:  This paper investigates the determinants of ownership changes of drug candidates in one of the most important current pharma markets —the market for diabetes. We in particular look at how do the competitive circumstances, progress in clinical development and radicalness of the drug candidates matter in these decisions. We use newly constructed, very granular dataset tracking ...

Abstract:   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 lacking. In this paper, we show that data as an input into machine learning tasks displays features that favor the hypothesis that data is a source of market power. We study the search result quality for search keywords on ...

Abstract:   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 impacts consumer decisions through salience effects, its consumer ...
