We study the influence of reason and intuition on decision making over time. Facing a sequence of similar problems …, agents can either decide rationally according to expected utility theory or intuitively according to case-based decision …

This paper studies experimentally when and how ideological motives shape outcomes in group decision-making scenarios …

models typically assume an individual rational decision maker. A rapidly growing body of (experimental) literature … decision-making rules (unanimity, majority). We find that teams contribute significantly more and punish less than individuals …, regardless of the team decision rule. Overall, teams yield higher payoffs than individuals. …

; 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) and one involving social decision-making (Externality). Analyses of … individual and social contexts, and that transferring decision-making power to groups can lead to a “liberal shift”. …

In prosocial decisions, decision-makers are inherently uncertain about how their decisions impact others’ utility – we …
