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...

Visual Continuous Time Preferences (VCTP) is 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 this tool in the field, in rural Honduras, to test whether running the task with...

Measuring risk preferences in the field is critical for policy, however, it can be costly. For instance, the commonly used measure of Holt and Laury (2002) relies on a dozen lottery choices and payments which makes it time-consuming and costly. We propose a short version of the Holt and Laury...

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...
