This paper presents results from a modified dictator experiment aimed at distinguishing and quantifying the two intrinsic motivations for giving: warm glow and pure altruism. In particular, we implemented a within-subject experimental design with three treatments: (i) one, T1, where the...

In the current study we explore whether enriching the brain's supply of glucose will improve the quality and speed of decision making. Prior research shows that glucose enrichment supports cognition and more recent research has shown it can improve decision making on some tasks. To test our...

We investigate the consistency and stability of individual risk preferences by manipulating cognitive resources. Participants are randomly assigned to an experiment session at a preferred time of day relative to their diurnal preference (circadian matched) or at a non-preferred time (circadian...

Societies prohibit many transactions considered morally repugnant, although potentially efficiency-enhancing. We conducted an online choice experiment to characterize preferences for the morality and efficiency of payments to kidney donors. Preferences were heterogeneous, ranging from...

We challenge a commonly used assumption in the literature on social preferences and show that this assumption leads to significantly biased estimates of the social preference parameter. Using Monte Carlo simulations, we demonstrate that the literature's common restrictions on the curvature of...

How does pay-for-performance (P4P) impact productivity, multitasking, and the composition of workers in mission-oriented jobs? These are central issues in sectors like education or healthcare. We conduct a laboratory experiment, manipulating compensation and mission, to answer these questions....

We show that the disposition to focus on favorable or unfavorable outcomes of risky situations affects willingness to take risk as measured by the general risk question. We demonstrate that this disposition, which we call risk conception, is strongly associated with optimism, a stable facet of...
