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

    Speaker: Maximilian Schäfer
    Location: Online seminar via Cisco Webex
    Time:
    13:45 - 14:45

    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 (canceled)

    Speaker: Tomaso Duso
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time:
    10:30 - 11:30
    - 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 ...

    Decomposing Trust

    Speaker: Jana Friedrichsen
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 10:30 - 11:30

    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 ...

    Optimal Benefit-Based Corporate Income Tax

    Speaker: Simon Naitram, University of the West Indies, Cave Hill
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 13:15 - 14:30

    Abstract:   I derive an optimal benefit-based corporate tax rate formula as a function of the public input elasticity of profits and the (net of) tax elasticity of profits. I argue that the existence of the corporate income tax should be justified by the benefit-based view of taxation: firms should pay tax according to the benefits they receive from the use of the public input. I argue that ...

    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 10:30 - 11:30

    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 ...

    Knowledge Spillover and Individual Careers

    Speaker: Thomas Cornelissen, University of York
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 13:15 - 14:30

    Abstract: Through social interaction in the workplace, coworkers are likely to learn from each other (knowledge spillover) and this may extend the returns to firm-provided training from trained workers onto untrained coworkers. Based on German matched-employer employee data covering the universe of employees we investigate whether unskilled workers derive long-term career benefits if they were ...

    Data Network Effects: The Example of Internet Search

    Speaker: Maximilian Schäfer
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 11:00 - 11:30

    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 ...

    Partitioned Pricing and Consumer Welfare

    Speaker: Kevin Ducbao Tran
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 10:30 - 11:00

    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 ...

    Antibiotic Prescribing and Diagnostic Testing: Physician Behavior in the Case of Urinary Tract Infection

    Speaker: Shan Huang
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 10:30 - 11:00

    Abstract: When a patient with symptoms of urinary tract infection arrives at a physician's office, it needs to decide which antibiotic drug to prescribe. A drug's efficacy in treating the infection depends on the individual, time-dependent resistance profile of the bacterium causing the infection. Physicians can conduct antibiotic susceptibility tests in order to create current resistance profiles ...

    State-owned Firms and Payout Policy - Evidence from German Municipal Firms

    Speaker: Astrid Cullmann, DIW Berlin & TU Berlin
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 10:30 - 11:30

    This study investigates the payout policy of state-owned municipal firms. Based on insights from agency theory we derive an empirically testable model based on Lintner's corporate dividend policy model accounting for the characteristics of state-owned firms in terms of corporate governance and ownership structure. Exploiting a large and new panel dataset on German firms from the years 2003 to 20 ...

    Mothers Working during Preschool Years and Child Skills. Does Income Compensate?

    Speaker: Emma Tominey, University of York
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 13:15 - 14:30

    Abstract: Increasing mothers’ labour supply in a child’s preschool years can cause a reduction in time investments that can lead to a negative direct effect on mid-childhood and teenage outcomes. As mothers’ work hours increase, income will rise and we ask whether income can compensate for the negative effect of hours by adopting a novel mediation analysis that exploits exogenous ...

    Choosing between Explicit Cartel Formation and Tacit Collusion – An Experiment

    Speaker: Maximilian Andres, University of Potsdam
    Location: Anna J. Schwartz Room
    Room 5.2.010
    Mohrenstraße 58
    10117 Berlin
    Time: 10:30 - 11:30

    Abstract: Antitrust authorities try to detect and sanction existing cartels and hinder the formation of new ones. Firms nevertheless try to collude while avoiding sanctions, for example by colluding tacitly instead of explicitly forming a cartel. In this paper, we focus on differences in the communication of firms that either form an explicit cartel or try to collude tacitly. The latter may still ...
