We study ethnic discrimination in the sharing economy using example of online carpooling marketplaces. Based on a unique data set 16,624 real rides from Germany, we estimate effects drivers' perceived name origins demand for rides. The results show sizable discrimination—a discriminatory price premium about 32 per cent average market price. Further analyses suggest that additional information actors this decreases magnitude discrimination. Our findings broaden perspective by shedding light...
Does competition affect moral behavior? This fundamental question has been debated among leading scholars for centuries, and more recently, it tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source ambivalent results on the same hypothesis is design heterogeneity-variation true effect sizes across various reasonable research protocols. To provide further evidence whether affects behavior to examine generalizability single study...
This study analyzes deterrence schemes and their impact on stealing. The results confirm Becker’s hypothesis. Moreover, crowding out of pro-social behavior occurs due to incentives: when incentives first exist are removed later on, subsequent is more selfish than without this history. offers evidence that (part this) takes place via change emotions. Without in place, a variant the dictator game, players with emotions steal less. When face expected punishment, deactivated do not decrease...
This paper investigates two channels of prosociality: indirect reciprocity and charitable giving. We conducted a natural field experiment in hair salon Hamburg, Germany, over the course four months. In baseline, we collected data on customers’ tips—a scenario absent donations. treatments had hairdresser collect donations to charity. one treatment pointed out opportunity donate. Our indicate that voluntary activity collecting led greater tips for significant second treatment, unconditionally...
We investigate how exposure to large-scale farms affects smallholders' competitive behavior. Based on lab-in-the-field experimental measures covering more than 900 smallholders and 400 children in Zambia, we find that who are traditionally dependent subsistence agriculture behave competitively when they located close farms. This effect is especially pronounced for female closes the gender gap associated with competitiveness. result replicates their children. identify employment shifting...
Abstract Following the 2007–8 global food crisis, agricultural producers have invested in large tracts of land developing countries. We investigate how arrival large-scale farms changes inter-personal trust and reciprocity, important components social capital, traditional villages. elicit reciprocal behaviour villages that lie near compare them with at a distance. Our data reveal greater close to farms. Reciprocity is more frequent after farm employment. These results are likely driven by...
Understanding what determines the truth-telling of economic agents towards their regulator is major importance from banking to management common-pool resources such as European fisheries. By enacting a discard-ban on unwanted fish-catches without increasing monitoring activities, Union (EU) depends fishermen's truth-telling. Using coin-tossing task in an artefactual mail field experiment with 120 German commercial fishermen, we test whether baseline setting differs behavior two treatments...
A growing literature in economics studies ethical behavior and honesty, as it is imperative for functioning societies a world of incomplete information contracts. majority found more pronounced dishonesty among teams compared to individuals. Scholars identified certain nudges effective cost-neutral measures curb individuals' dishonesty, yet little known about the effectiveness such teams. We replicate seminal nudge treatment effect, signing on top reporting form vs. no signature, with...
We study ethnic discrimination in the sharing economy using example of online carpooling marketplaces. Based on a unique dataset 16,624 real rides from Germany, we estimate effects drivers’ perceived name origins demand for rides. The results show sizable – discriminatory price premium about 32% average market price. Further analyses suggest that additional information actors this decreases magnitude discrimination. Our findings broaden perspective by shedding light subtle, everyday forms...
Academic honesty is crucial for scientific advancement, yet replication crises and misconduct scandals are omnipresent. We provide evidence on scientists’ truth-telling from two incentivized coin-tossing experiments with more than 1,300 scientists. Experiment I, predominantly European North-American scientists, shows that fewer scientists over-report winning tosses when their professional identity salient. The global II yields heterogeneous effects. replicate I’s effect but find the opposite...
Wir diskutieren Ergebnisse einer Studie über die Akzeptanz und Effektivität kognitiver moralischer Nudges am Beispiel von Standardeinstellungen sozialer Information. Unsere Studienteilnehmenden ordnen diese beiden Dimensionen unterschiedlich ein. Im Fokus des Beitrags stehen neben den Wirkmechanismen der auch Unterschiede in gesellschaftlichen persönlichen Zielen, denen angewendet werden sollen. Die Teilnehmenden unserer bevorzugen moralische für gesellschaftliche Ziele kognitive persönliche...
