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...

This paper combines several large-scale surveys with different identification strategies to shed new light on the determinants of cooperative behavior. We provide evidence indicating that the well-being maximizing level of trust is above the income maximizing level. Higher trust is also linked...

This study investigates the effects of unfair enforcement of institutional rules on public good contributions, personal and social norms, and trust. In a preregistered online experiment (n = 1,038), we find that biased institutions reduce rule compliance compared to fair institutions. However,...

The paper analyses the effects of the monetary policy crisis management of the European Central Bank on the economic order of Germany. It is argued that in post-war Europe the German social market economy as designed by Eucken (1952) and Müller-Armack (1966) has been a core element of growth,...

We experimentally study decentralized one-to-one matching markets with transfers. We vary the information available to participants, complete or incomplete, and the surplus structure, supermodular or submodular. Several insights emerge. First, while markets often culminate in efficient...

We investigate the strategies of a data intermediary selling consumer information to firms for price discrimination purpose. We analyze how the mechanism through which the data intermediary sells information influences how much consumer information she will collect and sell to firms, and how it...

We study competition among market designers who create new trading platforms, when boundedly rational traders learn to select among them. We ask whether efficient platforms, leading to market - clearing trading outcomes, will dominate the market in the long run. If several market designers are...

The public finance literature demonstrates the equivalence between consumption and labor income (wage) taxes. We construct an environment in which individuals make real labor-leisure choices and spend their earned income on real goods. We use this experimental framework to test whether a labor...

This paper analyses the optimal tax policy and public provision of private goods when individuals differ in two respects: income-earning ability and rationality. Publicly provided goods should be overprovided or subsidised, relative to the decentralised optimum, if society's marginal valuation...

Research in behavioral economics has uncovered the widespread phenomenon of people making decisions against their own good intentions. In these situations, the government might want to intervene, indeed individuals might want the government to intervene, to induce behavior that is closer to what...
