摘要：Rideshare drivers pay a proportion of their fares to a ride-hailing platform operator, a commission-based compensation model used by many service providers. To Uber drivers, this commission is known as the Uber fee. By contrast, traditional taxi drivers in most US cities make a fixed payment independent of their earnings, usually a weekly or daily medallion lease, keeping every fare dollar net of lease costs and other expenses. We assess these compensation models using an experiment that offer...

摘要：This paper studies the effects of adding criminal offenders to a DNA database. Using a large expansion of Denmark's DNA database, we find that DNA registration reduces recidivism within the following year by up to 42 percent. It also increases the probability that offenders are identified if they recidivate, which we use to estimate the elasticity of crime with respect to the detection probability and find that a 1 percent higher detection probability reduces crime by more than 2 percent. We a...

摘要：We study the effect of privatizing Medicaid drug benefits on drug prices and utilization. Drug spending would decrease by 21.3 percent if private insurers administered all drug benefits. One-third of the decrease is driven by private insurers' ability to negotiate prices with pharmacies. The remaining two-thirds is driven by the greater use of lower cost drugs, such as generics, and is only realized in states that give private insurers the flexibility to design drug benefits. Privatization doe...

摘要：Rapid urbanization is reshaping economies and intensifying spatial inequalities. In Bangladesh, we experimentally introduced mobile banking to very poor rural households and family members who had migrated to the city, testing whether mobile technology can reduce inequality by modernizing traditional ways to transfer money. One year later, for active mobile banking users, urban-to-rural remittances increased by 26 percent of the baseline mean. Rural consumption increased by 7.5 percent, and ex...

摘要：Most measures of deprivation concentrate on deprivation among the living population and, thus, ignore premature mortality. This omission leads to a severe bias in the evaluation of deprivation. We propose two different measures that combine information on poverty and premature mortality of a population. These measures are consistent and satisfy a number of desirable properties unmet by all other measures combining early mortality and poverty. Moreover, one measure is readily computable with av...

摘要：We study whether subways alleviate road congestion by examining 45 subway line launches in China and by using detailed data on road speed. Our difference-in-differences estimation finds that in the first year after a subway line is launched, rush hour speed on nearby roads increases by about 4 percent. The effect is most prominent in initially congested roads and declines over distance to the new subway line. Evidence on road speed is corroborated with substitution patterns among modes of tran...

摘要：Does political corruption erode civic values and foster dishonest behavior? I test this hypothesis in the context of Mexico by combining data on local government corruption and cheating on school tests. I find that, following revelations of corruption by local officials, secondary students' cheating on cognitive tests increases significantly. The effect is large and robust and persists for over a year after malfeasance is revealed. These findings are validated by evidence from individual surve...
