The regulation of many activities depends on whether societies consider them morally controversial or “repugnant.” Not only have regulation and related ethical concerns changed over time, but there is also heterogeneity across countries at a given time. We provide evidence of this heterogeneity for three morally contentious activities, abortion, prostitution, and gestational surrogacy, and explore the relationship between a country's economic conditions and how these activities are regulated. We propose a conceptual framework to identify mechanisms that can explain our findings (including the role of non-economic factors), and indicate directions for future research

As economists increasingly help governments design new policies and regulations, they take on an added responsibility to engage with the details of policy making and, in doing so, to adopt the mindset of a plumber. Plumbers try to predict as well as possible what may work in the real world, mindful that tinkering and adjusting will be necessary since our models gives us very little theoretical guidance on what (and how) details will matter. This essay argues that economists should seriously engage with plumbing, in the interest of both society and our discipline

Price and quantity interventions intended to affect assignments are common in many labor and education markets (e.g., financial aid, quotas). This article discusses an empirical framework, based on the theory of stable matching, that is suitable for policy analysis while accounting for the presence of equilibrium sorting. It then compares financial incentives and supply interventions for encouraging the training of family medicine residents in rural America. Due to equilibrium effects, the primary effect of financial incentives is to increase the quality, not numbers, of residents in rural programs, while quantity regulations directly affect numbers without adversely affecting quality

Moralistic punishment enables human cooperation, but an outstanding question is why people voluntarily sanction when they can obtain the benefits of punishment without being enforcers themselves. To address how decentralized societies solve this second-order free rider issue, I examine why people punish among the Turkana, a population in Kenya in which informal peer sanctioning sustains participation in high-stakes interethnic warfare. Using vignette experiments I show that Turkana subjects express punitive sentiments toward second-order free riders and those who sanction irresponsibly. The prevalence of such meta norms regulating punishment reveal a possible pathway by which moralistic punishment could have evolved

We develop a structural empirical model of the US banking sector. Insured depositors and run-prone uninsured depositors choose between differentiated banks. Banks compete for deposits and endogenously default. The estimated demand for uninsured deposits declines with banks' financial distress, which is not the case for insured deposits. We calibrate the supply side of the model. The calibrated model possesses multiple equilibria with bank-run features, suggesting that banks can be very fragile. We use our model to analyze proposed bank regulations. For example, our results suggest that a capital requirement below 18 percent can lead to significant instability in the banking system

We show that a number of noncognitive skills and preferences, including patience and identity, are malleable in adults, and that investments in them reduce crime and violence. We recruited criminally engaged men and randomized one-half to eight weeks of cognitive behavioral therapy designed to foster self-regulation, patience, and a noncriminal identity and lifestyle. We also randomized $200 grants. Cash alone and therapy alone initially reduced crime and violence, but effects dissipated over time. When cash followed therapy, crime and violence decreased dramatically for at least a year. We hypothesize that cash reinforced therapy's impacts by prolonging learning-by-doing, lifestyle changes, and self-investment

Most approaches to entrepreneurship assume that entrepreneurial control over their inventions is critical for success and, in turn, for incentives. Such control is usually supported by regulations that protect intellectual property including patents, copyrights, and trade secrets. Each give the entrepreneurs control over who can appropriate value from their activities. However, we note that another, distinct path exists for appropriation by entrepreneurs' execution. Execution forgoes the formal protection from control instead of a more rapid approach to market in the pursuit of capabilities that will allow entrepreneurs to compete with others in the future rather than block their activities per se. We characterize the conditions under which one path is preferred to another and present evidence from university startups delineating the tradeoffs at the heart of our theoretical approach

We estimate a model of illicit drugs markets using data on purchases of crack cocaine. Buyers are searching for high-quality drugs, but they determine drugs' quality (i.e., their purity) only after consuming them. Hence, sellers can rip off first-time buyers or can offer higher-quality drugs to induce buyers to purchase from them again. In equilibrium, a distribution of qualities persists. The estimated model implies that if drugs were legalized, in which case purity could be regulated and hence observable, the average purity of drugs would increase by approximately 20 percent and the dispersion would decrease by approximately 80 percent. Moreover, increasing penalties may raise the purity and affordability of the drugs traded by increasing sellers’ relative profitability of targeting loyal buyers versus first-time buyers

We study the effect of financial relationships on firms' investment decisions and access to external finance. In the early twentieth century, securities underwriters commonly held directorships with American corporations. Section 10 of the Clayton Antitrust Act prohibited bankers from serving on the boards of railroads for which they underwrote securities. We find that following the implementation of Section 10, railroads with strong preexisting relationships with underwriters saw declines in their investment rates, valuations, and leverage, and increases in their costs of external funds. Reassuringly, we do not observe similar effects among industrials and utilities, which were not subject to Section 10. Our results are consistent with underwriters on corporate boards acting as delegated monitors, and highlight the potential for regulations intended to address conflicts of interest to disrupt valuable information flows
