We ran an experiment to study whether lack of control has an effect on experimental results. Subjects who were recruited following standard procedures completed the experiment online or in the laboratory. The experimental design is otherwise identical between conditions. Results suggest that...

The original standard for measuring time preferences was Multiple Price List (MPL), where subjects are asked to choose between an amount of money in the present and a larger amount of money in the future. Convex Time Budget (CTB) was later introduced, allowing subjects to differentially allocate...

We introduce the Visual Continuous Time Preferences (VCTP) task, a new tool for measuring time preferences that synthesizes the simplicity of Multiple Price List (MPL) and the precision of Convex Time Budget (CTB) tasks. We evaluate VCTP in three environments: lab, field and high school. The lab...

The aim of many experiments is to estimate the effect of different interventions on subjects' decision making. However, obtaining large samples and internal validity is challenging. This paper presents an alternative device at almost no cost that can easily provide a very large number of...

Measuring risk preferences in the field is critical for policy, however, it can be expensive and may generate unequal payoffs due to bad luck. For instance, the commonly used measure of Holt and Laury (2002) relies on a dozen of lottery choices and payments which makes it time consuming and...
