Discrimination is an ubiquitous phenomenon in many societies, but little is known about its origins in childhood. In a framed field experiment, we let 142 three to six-year old preschool children allocate a fixed endowment between an in-group and an out-group receiver in two domains (gender and...

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...

In this paper, we report both field and laboratory experimental results on the effects of setting public versus private reserve prices in ascending auctions. The field experiments were performed with a large online used automobile seller. In addition to providing a check on the results of the...

We conduct trust games in three villages in a northeastern Romanian commune. From 1775-1919, these villages were arbitrarily assigned to opposite sides of the Habsburg and Ottoman/Russian border despite being located seven kilometers apart. All three empires were ruled by outsiders to Romania,...

We provide twelve best practices and discuss how each practice can help researchers accurately, credibly, and ethically use Generative AI (GenAI) to enhance experimental research. We split the twelve practices into four areas. First, in the pre-treatment stage, we discuss how GenAI can aid in...

We compare the performance of financial professionals (CFAs) with university students in four financial forecasting tasks ranging from simple lab prediction tasks to longitudinal field tasks. Although students and professionals performed similarly in the artificial forecasting tasks, their...

To investigate the external validity of laboratory results, we combine a public good experiment with three treatments in a field experiment. One treatment offers the opportunity to free-ride, the other two are placebo treatments. We compare results within subjects. In the free-riding treatment,...

The population of most developed societies is graying. As life expectancy increases and the large baby-boom generation approaches retirement age, this has critical consequences for maintaining a high standard of living and the sustainability of pension systems. In the light of these labor-force...

This study investigates how to use regression adjustment to reduce variance in experimental data. We show that the estimators recommended in the literature satisfy an orthogonality property with respect to the parameters of the adjustment. This observation greatly simplifies the derivation of...
