Loss aversion can occur in riskless and risky choices. Yet, there is no evidence whether people who are loss averse in riskless choices are also loss averse in risky choices. We measure individual-level loss aversion in riskless choices in an endowment effect experiment by eliciting both WTA and...

This paper analyzes the effect of information overload on preference or aversion for variety. According to the model, a rational decision maker who suffers from information overload, faces a two-stage decision process, and is choosing from a set of unknown goods will find it optimal at some...

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...

As illustrated by the famous Ellsberg paradox, many subjects prefer to bet on events with known rather than with unknown probabilities, i.e., they are ambiguity averse. In an experiment, we examine subjects’ choices when there is an additional source of ambiguity, namely, when they do not know...

We study risk aversion and prudence in medical treatment decisions. In a laboratory experiment, we investigate the frequency and intensity of second- and third-order risk preferences, as well as the effect of the medical decision context. Risk preferences are assessed through treatment...

A common premise in both the theoretical and policy literatures on development is that people remain poor because they are too impatient to save and too risk averse to take the sort of chances needed to accumulate wealth. The empirical literature, however, suggests that this assumption is far...

In this paper, we relax the hard closure property of experiments that have been used to study endowment effect in laboratory. We study differences in benchmark environments (hard closure) and an environment that allows participants to reverse the decisions taken in the laboratory (soft closure)....

We study in an experiment whether humans prefer to depend on decisions of other humans (social uncertainty) or states of nature (environmental uncertainty). In the social uncertainty treatments subjects depend only on past decisions of other humans. This is the first experiment that studies...

We study risk-aversion and prudence in medical treatment decisions. In a laboratory experiment, we investigate the frequency and intensity of second- and third-order risk preferences, as well as the effect of the medical decision context. Risk preferences are assessed through treatment...
