We find a strong relationship between risk-loving preferences and cognitive ability which becomes stronger as adherence to the generalized axiom of revealed preference (a proxy for rationality) increases. Our results are taken from a field study of individuals at the very bottom of the income...

Iran has the world's only government-regulated kidney market. We report the results of the first field study of donor behaviour in this unusual market. Participants have lower risk tolerance and higher patience levels than the Iranian average but display no difference in rationality from...

This paper investigates the effect of economic sanctions on employment. We exploit the imposition of a series of unexpected and unprecedented international economic sanctions on Iran in 2012 and estimate the short-run effects of the change in import exposure on manufacturing employment at the...

This paper examines how economic sanctions affect the allocation of workers across formal and informal employment. We analyse the case of the unprecedented sanctions imposed on Iran in 2012. Employing a difference-in-differences approach, we compare the probability of being employed in the...

The paper provides evidence that happiness raises productivity. In Experiment 1, a randomized trial is designed. Some subjects have their happiness levels increased, while those in a control group do not. Treated subjects have 12% greater productivity in a paid piece-rate Niederle-Vesterlund...

We live in a high-divorce age. It is now common for university faculty to have students who are touched by a recent divorce. It is likely that parents themselves worry about effects on their children. Yet there has been almost no formal research into the important issue of how recent...

We perform an incentivized experiment designed to assess the accuracy of beliefs about characteristics and decisions. Subjects are asked to declare some specific choices and characteristics with different levels of observability from an external point of view, and typically formed through real...

We present the first attempt to construct a long-run historical measure of subjective wellbeing using language corpora derived from millions of digitized books. While existing measures of subjective wellbeing go back to at most the 1970s, we can go back at least 200 years further using our...

Existing research supports two opposing mechanisms through which positive mood might affect cooperation. Some studies have suggested that positive mood produces more altruistic, open and helpful behavior, fostering cooperation. However, there is contrasting research supporting the idea that...

Though many in the general public are concerned about climate change, most are unaware that agriculture and food production accounts for about one quarter of aggregate green house emissions and therefore, diet change is one of the most effective ways that individuals can reduce their climate...
