Economic and social transformation of China during the past 40 years is without precedent in human history. While the economic transformation was extensively studied, social transformation was not. In this paper, we use for the first time harmonized household surveys covering the period 1988-2013 to study the changes in the characteristics of the richest 5 percent of China’s urban ...

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 ...

The high prevalence of forced migration in recent years has induced a shift in attitudes towards immigrants and refugees and, in turn, increasing xenophobic violence. We address this topic and estimate the effect of xenophobic attacks against refugee shelters on refugees’ mental health. For this purpose, we combine two innovative data sets: administrative records on xenophobic crime by ...

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 ...

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 ...

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 ...

(together with Fabian Kosse and Armin Falk) In this project we investigate the determinants of locus of control using data from the BRIQ Family Panel. Particular interest lies in the effectiveness of a one year mentoring intervention which targeted low SES children at the age of 7 to 9.We find that the mentoring intervention had no effect on locus of control in the first 5 waves ...

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 ...

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 ...

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 ...

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 ...
