An “information cascade” occurs when initial decisions coincide in a way that it is optimal for each of the subsequent individuals to ignore her or his private signals and follow the established pattern. Moscarini et. al (1996) developed a social learning model hitherto unexplored in an...

Die Theorie des Wettbewerbs als Entdeckungsverfahren behauptet, daß die Ergebnisse des Wettbewerbes nicht vorhergesagt werden können, weil hierzu Tatsachen benötigt würden, die durch ihn erst entdeckt werden sollen. Dann wäre es allerdings unmöglich, Aussagen über Wettbewerb empirisch zu...

Recent studies report that productivity increases under tournament reward structures than under piece rate reward structures. We conduct maze-solving experiments under both reward structures and reveal that overconfidence is a significant factor in increasing productivity. Specifically, subjects...

Since the seminal paper of Hoffman et al. (1994), an entitlement effect is believed to exist in the Ultimatum Game, in the sense that proposers who have earned their role (as opposed to having it randomly allocated) offer a smaller share of the pie to their matched responder. The entitlement...

At the initial stage of this project, the project group consisted of Asbjørn Aaheim, Magnus Hatlebakk and the authors. The authors are grateful for the discussion with the other project participants at this stage. We also had very useful discussion with the marine researcher Sigurd Tjelmeland...

One possible conclusion from recent experimental research on decision making under risk is that observed behaviour can be reasonable accommodated by expected utility plus an error term. This conclusion implies that the violation rate of expected utility should decrease if errors are excluded....

Economists long considered money illusion to be largely irrelevant. Here we show, however, that money illusion has powerful effects on equilibrium selection. If we represent payoffs in nominal terms, choices converge to the Pareto inefficient equilibrium; however, if we lift the veil of money by...

We report an experiment contrasting the impacts of a tax and a cap rule in a single-product market with two privately-informed buyers. We discuss the effects on choice set and consumer surplus. The policy environment varies across treatments. With regulations, we aim to halve the size of the...

This paper examines the role of social norms and political polarization in shaping vaccination attitudes and behaviors in the context of the Covid-19 pandemic. Using a largescale representative survey experiment in Turkey, we first show that political affiliation is a strong predictor of...

Public reputation mechanisms are an effective means to limit opportunistic behavior in markets suffering from moral hazard problems. While previous research was mostly concerned with the influence of exogenous feedback mechanisms, this study considers the endogenous emergence of reputation...
