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...

Gender differences are often observed in real life-situations. We implement an experiment on the investment game which explores the influence of knowledge of partner's gender in trust and reciprocity by means of two treatments of information: the first one, without knowledge of partner's gender...

Humans differ greatly in their tendency to discount future events, but the reasons underlying such inter-individual differences remain poorly understood. The evolutionary framework of Life History Theory predicts that the extent to which individuals discount the future should be influenced by...

Nothing is known about the effectiveness of defaults when moving the target outcome requires substantial post-intervention effort. With two field experiments in higher education, we investigate howdefaults fare in such situations. We change the exam signup procedure to "opt-out" for a single...

The purpose of the study is to better understand human capital investment decisions of the working poor, and to collect information that can be used to design a policy to induce the poor to invest in human capital. We use laboratory experimental methodology to elicit the preferences and observe...

Investment behavior is traditionally investigated with the assumption that risky investment is on average advantageous. However, this may not always be the case. In this paper, we experimentally studied investment choices made by students and financial professionals under favorable and...

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...

The use of hypothetical instead of real decision-making incentives remains under debate after decades of economic experiments. Standard incentivized experiments involve substantial monetary costs due to participants’ earnings and often logistic costs as well. In time preferences experiments,...

Results are reported of the first natural field experiment on the dictator game, where subjects are unaware that they participate in an experiment. In contrast to predictions of the standard economic model, dictators show a large degree of pro-social behavior. This paper builds a bridge from the...

There is evidence that 9-ending prices are more common and more rigid than other prices. We use data from three sources: a laboratory experiment, a field study, and a large US supermarket chain, to study the cognitive underpinning and the ensuing asymmetry in rigidity associated with 9-ending...
