This paper investigates if and how other-regarding preferences governing giving decisions in dictator games are affected in risky environments in which the payoff of the recipient is random. We demonstrate that, whenever the risk is actuarially neutral, the donation of dictators with a purely ex...

Prior research suggests that those who rely on intuition rather than effortful reasoning when making decisions are less averse to risk and ambiguity. The evidence is largely correlational, however, leaving open the question of the direction of causality. In this paper, we present experimental...

Influential economic approaches as random utility models assume a monotonic relation between choice frequencies and "strength of preference," in line with widespread evidence from the cognitive sciences, which also document an inverse relation to response times. However, for economic decisions...
