Abstract:  User generated content is increasingly substituting content created by professionals. Local news that is generated by citizen journalists could be a promising way of supporting the struggling newspaper industry by reducing costs for professional journalists. We study a network of 122 local Austrian newspapers operating a hybrid model of citizen and professional journalism. We first ...

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 ...

Household Finance 0.5 or 2.0? Eliciting Individuals’ Financial Decision-Making Approaches (canceled)

Speaker: Thomas Post, Maastricht University
Location: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Time:
13:15 - 14:30
- Canceled -

Abstract:   How exactly do individuals approach financial decisions? Do they apply sophisticated formulas, back of the envelope math, do they guess or something else? We show that literally asking individuals to explain their approaches generates new insights about those questions that are reliable and have predictive power out of sample. We find, for example, that when assessing the ...

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 ...

Battling Antibiotic Resistance: Can Machine Learning Improve Prescribing?

Speaker: Hannes Ullrich
Location: Anna J. Schwartz Room
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 ...

Time: Time change: 10:00 - 11:00

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 ...

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 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 ...

Salience of Inherited Wealth and the Support for Inheritance Taxation

Speaker: Daniel Waldenström, Research Institute of Industrial Economics (IFN), Stockholm
Location: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Time: 13.15 - 14.30

Abstract: We study how attitudes to inheritance taxation are influenced by information about the role of inherited wealth in society. Using a randomized experiment in a register-linked Swedish survey, we find that informing individuals about the large aggregate importance of inherited wealth and its link to inequality of opportunity significantly increases the support for inheritance taxation. The ...

Evaluation of Bidding Groups in First-price Auctions

Speaker: Christine Zulehner, University of Vienna
Location: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Time: 10:30 - 11:30

Abstract: In this paper, we analyze bidding groups that participate in procurement auctions. Our main question is to ask, whether in the absence of the joint bid, there could have been two or more independent bids and if yes, these bids yield a different final outcome. We utilize data from the Austrian construction sector and estimate models of first-price sealed-bid auctions with endogenous entry ...

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

Abstract: We examine experimentally the impact of corporate social responsibility techniques on individuals’ performance and willingness to compete. Our baseline treatment adopts the Niederle-Vesterlund (2007) paradigm whereby individuals perform a task under piece-rate and tournament incentives, followed by an opportunity to determine which of the two payment schemes they prefer. In our ...
