Two deviations of alternating-offer bargaining behavior from economic theory are observed together, yet have been studied separately. Players who could secure themselves a large surplus share if bargainers were purely self-interested incompletely exploit their advantage. Delay in agreement...

Atrial fibrillation (AF), a supraventricular tachycardia disorder, is the most common sustained cardiac arrhythmia affecting 1–2 % of the general population. Prevalence is highly related to age, with every fourth individual older than 40 years old developing AF during his lifetime. Due to an...

Experimental evidence from dictator games and simple choice situations indicates concerns for fairness and social welfare in human decision making. At the same time, models of inequality averse agents fail to explain the experimental data of individuals who reduce their payoff below a fair split...

This paper aims at assessing cultural differences in uncertainty attitude across Europe. We select questions from the European Values Survey (EVS) capturing salient features of uncertain scenarios ("safe versus uncertain", "freedom of choice" and "reduction of uncertainty"), and formalize these...

This Note studies the problem of implementing social choice correspondences in environments where individuals have doubts about the rationality of their opponents. We postulate the concept of [epsilon]-minimax regret as our solution concept and show that social choice correspondences that are...

We introduce tests for finite-sample linear regressions with heteroskedastic errors. The tests are exact, i.e., they have guaranteed type I error probabilities when bounds are known on the range of the dependent variable, without any assumptions about the noise structure. We provide upper bounds...

The introduction of sanctions provides incentives for more pro-social behavior, but may also be a signal that non-cooperation is prevalent. In an experimental minimum-effort coordination game we investigate the effects of the information contained in the choice to sanction. We compare the effect...

This paper introduces the concept of ordient for binary relations (preferences), a relative of the concept of gradient for functions (utilities). Ordients have a natural economic interpretation as marginal rates of substitution. Some examples of ordientable binary relations include the...

This paper introduces a new solution concept, a minimax regret equilibrium, which allows for the possibility that players are uncertain about the rationality and conjectures of their opponents. We provide several applications of our concept. In particular, we consider price-setting environments...
