The failure of foreign aid to promote growth in the developing world has received significant attention as evidence suggests that foreign aid does not translate into investment. This research has demonstrated that poor institutions in these developing economies (particularly with respect to...

This paper reports results from a unique two-stage experiment designed to examine the spillover effects of optimism and pessimism. In stage 1, we induce optimism or pessimism onto subjects by randomly assigning a high or low piece rate for performing a cognitive task. We find that participants...

A two-stage experiment was designed to examine spillover effects of a type of optimism/pessimism. We first exploit cognitive dissonance to induce optimism/pessimism by random assignment of high/low piece rates for performing a task. Subjects receiving the low piece rate are significantly more...

Recent evidence suggests that nearly 25% of U.S. adults (47 million) suffer from some level of sleep deprivation. The impact of this sleep deprivation on the U.S. economy includes direct medical expenses related to sleep deprivation and related disorders, the cost of accidents, and the cost of...

People differ in their diurnal (time-of-day) preferences—some are morning-types and others are evening-types. These differences are explored in a unique experiment design in which subjects are randomly assigned to produce paper airplanes at either 8:00 a.m. or 10:00 p.m. Our results show that...

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 examine the impact of glucose on a Bayesian choice task that creates a separating equilibrium between high-level Bayesian choice and lower-level reinforcement heuristic choice. Consistent with a dual systems framework, we hypothesize that glucose administration will both increase reaction...

Experimental studies have shown that sanctions effectively deter free riding within groups. However, the over-use of costly punishment may actually harm overall welfare. A main reason for over-punishment is that free-riders generate negative emotions that likely favor excessive punishments. In...

When membership in a particular group conveys valuable information about an individual’s skills, productivity, or other human capital characteristics, a non-prejudiced agent may still find it rational to statistically discriminate. We frame statistical discrimination in a labor market setting...

Do individuals trained in law enforcement punish or rewards differently from typical student subjects? We analyze norm enforcement behavior of newly appointed police commissioners in both a Voluntary Contribution Mechanism game and a Common Pool Resource game. Our experimental design includes...
