摘要：Primary care is the most frequently utilized health service and is the source of nearly half of all opioids prescribed in the United States. This paper studies the impact of exposure to high prescribing primary care providers (PCP) on opioid use, opioid use disorder, and mental health. Using electronic health records, we exploit within-facility quasi-random assignment of providers, who differ in their opioid prescribing tendency, to 650,000 new patients enrolling in care with the Veterans Heal...

摘要：The interactions between minimum wage policy and tax evasion remain largely unknown. We study the firm -level employment effects of a large and biting minimum wage increase in the context of widespread wage underreporting. We apply machine learning to classify firms as either tax-compliant or tax-evading. We then show that firms engaged in labor tax evasion are insensitive to the minimum wage shock. Our results indicate that these firms use wage underreporting as an adjustment margin, converti...

摘要：Citizens' support is crucial to effectively combat organized crime, a substantial threat to many countries. Contrary to prior studies identifying a negative correlation between crime and trust in the state, studying a representative sample of 5374 individuals in Italy we find that exposing the participants to journalistic images of organized crime-related violence increases trust towards institutions and state performance (measured by donations to a governmental as opposed to a non-governmenta...

摘要：Environmental externalities from cryptomining may be large, but have not been linked causally to mining incentives. We exploit daily variation in Bitcoin price as a natural experiment for an 86 megawatt waste coal-fired power plant with on-site cryptomining. We find that carbon emissions respond swiftly to mining incentives, with price elasticities of 0.69-0.71 in the short-run and 0.33-0.40 in the longer run. A $1 increase in Bitcoin price leads to $3.11-$6.79 in external damages from carbon ...

摘要：Subsidization of urban public transportation systems is often motivated by economies of scale and second-best considerations such as an underpriced road alternative. We model a public transit line sub-ject to frictions between users (in-vehicle crowding), users and vehicles (boarding and alighting delays), and vehicles (congestion). We derive the profit-and welfare-maximizing provisions of supply. We show that if demand exceeds a first threshold, the system enters a congested regime and servic...

摘要：What determines the quality of a nation's infrastructure? We show that electoral incentives at the time of construction have persistent effects on the functionality of contemporary African water systems. We apply a common event-study approach to the universe of water points in Nigeria, Sierra Leone, and Tanzania built over the period from 1970-2014. Across all three settings, we find that infrastructure installed in the run-up to an election is significantly more likely to be functioning today...

摘要：In contexts with weak enforcement, the threat of tax evasion may constrain policy makers' power to set tax policies optimally. This paper studies whether stricter tax enforcement affects the tax schedule set by local governments. I take advantage of an Italian policy that generated cross-municipality variation in the scope for tackling income and property tax evasion through stricter tax enforcement. Combining an event-study design with municipality-level panel data on statutory tax rates, I s...

摘要：We study the effect of the Supplemental Nutrition Assistance Program (SNAP) on retail prices nationwide. State-level program adjustments motivate our identification strategy. A 1% increase in benefits per population raises grocery prices by a persistent 0.08%. A calibrated partial-equilibrium model implies a marginal benefit dollar raises a recipient's consumer surplus from groceries by $0.7, producer surplus by $0.5, and lowers each non-SNAP consumer's surplus by $0.05, because of a large mar...

摘要：There are two common views of pork barrel spending. One is that pork barrel spending benefits special interests at the expense of social welfare, hence antithetical to responsible policy making, especially in times of crisis. An alternative is that pork greases the legislative wheelsmaking possible the enactment of socially beneficial legislation that would otherwise not pass. In this paper we reexamine both arguments and show that they depend on the nature of heterogeneity of interests and in...

摘要：This paper measures how labor regulations affect the structure of earnings and employment in other occupations in the context of occupational licensing. Using a state boundary discontinuity design, I estimate the market spillovers of licensing on other occupations with similar skills, which I classify using hierarchical clustering techniques on skills data from O*NET. I find evidence of negative earnings and employment spillovers, with the largest earnings effects concentrated among women, bla...
