We conducted a controlled field experiment on eBay and examined to what extent both social and competitive laboratory behavior is robust to institutionally complex real world markets with experienced traders, who selected themselves into these markets. EBay's natural trading system provides...

Many Internet markets rely on feedback systems', essentially social networks of reputation, to facilitate trust and trustworthiness in anonymous transactions. Market competition creates incentives that arguably may enhance or curb the effectiveness of these systems. We investigate how different...

Feedback withdrawal mechanisms in online markets aim to facilitate the resolution of conflicts during transactions. Yet, frequently used online feedback withdrawal rules are flawed and may backfire by inviting strategic transaction and feedback behavior. Our laboratory experiment shows how a...

This study examines human ordering behavior in service‐level inventory contracts, a class of contracts important in practice. Studies of wholesale price contracts find that people tend to place orders that are suboptimal and biased toward mean demand. Unlike wholesale price contracts,...

Both theory and recent empirical evidence on nudging suggest that observability of behavior acts as an instrument for promoting (discouraging) pro-social (anti-social) behavior. Our study questions the universality of these claims. We employ a novel four-party setup to disentangle the roles that...

Both theory and recent empirical evidence on nudging suggest that observability of behavior acts as an instrument for promoting (discouraging) pro-social (anti-social) behavior. We connect three streams of literature (nudging, social preferences, and social norms) to investigate the universality...

Using a series of controlled laboratory experiments involving decisions to intervene in others' choice opportunities; we find that groups grant more autonomy to others than individuals. This finding is robust across two decision contexts, one involving individual decision-making (Internality)...

International climate negotiations have so far failed to produce ambitious climate cooperation. We combine laboratory experiments with simulations to investigate the performance of two negotiation design features to address this failure: The Paris Agreement's ratchet-up mechanism, which requires...

Die Situation ist sehr ernst. Etliche Gaskunden werden im Winter ihre Heizung herunterdrehen oder ihre Produktion herunterfahren müssen. Je kälter der Winter, desto größer das Problem. Ökonomen sind sich weitgehend einig, dass die Politik die Entscheidung, wer wie viel Gas einspart, dem...
