We measure the impact of individuals' looks on life satisfaction/happiness. Using five data sets, from the U.S., Canada, the U.K., and Germany, we construct beauty measures in different ways that allow placing lower bounds on the effects of beauty. Beauty raises happiness: A one...

We usually consider it progress when a country begins to shift from an autocratic to a democratic form of government. However, the introduction of elections and other early trappings of democracy often has the perverse effect of exacerbating political instability. It also increases the...

The importance of evolutionary forces for comparative economic performance across societies has been the focus of a vibrant literature, highlighting the roles played by the Neolithic Revolution and the prehistoric "out of Africa" migration of anatomically modern humans in generating worldwide...

We examine how machine learning can be used to improve and understand human decision-making. In particular, we focus on a decision that has important policy consequences. Millions of times each year, judges must decide where defendants will await trial--at home or in jail. By law, this decision...

Research shows that properly devised economic incentives increase the supply of blood without hampering its safety; similar effects may be expected also for other body parts such as bone marrow and organs. These positive effects alone, however, do not necessarily justify the introduction of...

We document four similarities between American human healthcare and American pet care: (i) rapid growth in spending as a share of GDP over the last two decades; (ii) strong income-spending gradient; (iii) rapid growth in the employment of healthcare providers; and (iv) similar propensity for...

We investigate whether patents on human genes have affected follow-on scientific research and product development. Using administrative data on successful and unsuccessful patent applications submitted to the US Patent and Trademark Office, we link the exact gene sequences claimed in each...

We develop a numerical life-cycle model with choice over consumption and leisure, stochastic mortality and labor income processes, and calibrated to U.S. data to characterize willingness to pay (WTP) for mortality risk reduction. Our theoretical framework can explain many empirical findings in...

Does temperature affect economic performance? Has temperature always affected social welfare through its impact on physical and cognitive function? While many economic studies have explored the indirect links between climate and welfare (e.g. agriculture, conflict, sea-level rise), few address...

This research argues that deep-rooted factors, determined tens of thousands of years ago, had a significant effect on the course of economic development from the dawn of human civilization to the contemporary era. It advances and empirically establishes the hypothesis that, in the course of the...
