Data Network Effects: The Example of Internet Search

Speaker: Maximilian Schäfer
Ort: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Zeit: 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
Ort: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58

Zeit: 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 ...

Zeit: 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 ...

A question of gender: How promotions affect earnings

Speaker: Aline Zucco
Ort: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Zeit: 12:30 - 13:30

Occupational positions can explain an important part of the differences in pay between men and women. However, a considerable Gender Pay Gap exists even within the same occupational position. In this paper, we aim at understanding the reason for the gap within occupational positions and, therefore, investigate whether promotions lead to the same effect on earnings growth for men and women. ...

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 201 ...

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

Speaker: Emma Tominey, University of York
Ort: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Zeit: 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 ...

Average Wage Gaps and Expected Wage Cuts - An Investigation of Selection Neglect Bias in Income Expectations

Speaker: Annekatrin Schrenker
Ort: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Zeit: 12:30 - 13:30

Economists spend much of their lives talking about and correcting for sample selection. Recent evidence from behavioral economics documents that participants in lab experiments don't account for selection effects when they interpret conditional distributions. This "selection neglect" can distort expectations in settings where individuals learn from comparisons with other people who differ in ...

Choosing between Explicit Cartel Formation and Tacit Collusion – An Experiment

Speaker: Maximilian Andres, University of Potsdam
Ort: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Zeit: 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 ...

The New Top-Wealth Sample - First Impressions

Speaker: Carsten Schröder, Johannes König
Ort: Anna J. Schwartz Room
Room 5.2.010
Mohrenstraße 58
10117 Berlin
Zeit: 12:00 - 13:00

Top-wealth holders are typically underrepresented or completely missing in population surveys. The lack of comprehensive national registers on high-wealth individuals in many countries challenged previous attempts to remedy this under-representation. In a novel research design, we draw on public data on the shareholding structures of companies as a sampling frame. Our design builds on the ...

DIW Berlin
Room 3.3.002c
Mohrenstr. 58

Zeit: 12:30 - 14:00

We study how different network targeting mechanisms affect the direct and spillover impacts of a school-based health intervention in Zambia. Across 133 schools, we randomly assigned whether the intervention was administered to i) a random selection of students; ii) most central students; or iii) most central students and an additional friend. Our results indicate that the two-hour intervention had ...

This paper examines the causal impact of later retirement on outpatient care consumption among the French elderly. Outpatient care are defined as all the care provided out of the hospital setting. This question is of interest since spill effects may arise if later retirement increases health care expenditures. To deal with reverse causality issue, I use, as an instrumental variable, the 1993 ...
