Ambiguous prospects are ubiquitous in social and economic life, but the psychological foundations of behavior under ambiguity are still not well understood. One of the most robust empirical regularities is the strong correlation between attitudes towards ambiguity and compound risk which...

I show that stochastic contracts generate powerful incentives when agents suffer from probability distortion. When implementing these contracts, the principal can target probability distortions in order to inflate the agent's perceived benefits of exerting high levels of effort. This novel...

Facing climate change, seasonal forecasts, and weather warnings are increasingly important to warn the public of the risk of extreme climate conditions. However, being confronted with inaccurate forecast systems may undermine individuals' responsiveness in the long run. Using an online...

Since formal rules can only partially reduce opportunistic behavior, third-party sanctioning to promote fairness is critical to achieving desirable social outcomes. Social norms may underpin such behavior, but they can also undermine it. We study one such norm the "don't be a toad" norm, as it...

In prosocial decisions, decision-makers are inherently uncertain about how their decisions impact others’ utility – we call this interpersonal uncertainty. We show that people’s response to interpersonal uncertainty shapes well-known patterns of prosocial behavior. First, using standard...

This paper presents the Bomb Risk Elicitation Task (BRET), an intuitive procedure aimed at measuring risk attitudes. Subjects decide how many boxes to collect out of 100, one of which containing a bomb. Earnings increase linearly with the number of boxes accumulated but are zero if the bomb is...

The paper presents the results of a novel experiment testing the effects of environment complexity on strategic behavior, using a centipede game. Behavior in the centipede game has been explained either by appealing to failures of backward induction or by calling for preferences that induce...

This manual describes a z-Tree (Fischbacher, 2007) implementation of the paper-based Social Vaule Orientation (SVO) Slider Measure by Murphy et al. (2011). Using the paper-based version instead of the slider-based version (as implemented on the SVO-Website) avoids server-traffic related delays...
