Yes, in a nutshell, as Gordon Tullock used to claim:
Are states led by women less prone to conflict than states led by men? We answer this question by examining the effect of female rule on war among European polities over the 15th-20th centuries. We utilize gender of the first born and presence of a female sibling among previous monarchs as instruments for queenly rule. We find that polities led by queens were more likely to engage in war than polities led by kings. Moreover, the tendency of queens to engage as aggressors varied by marital status. Among unmarried monarchs, queens were more likely to be attacked than kings. Among married monarchs, queens were more likely to participate as attackers than kings, and, more likely to fight alongside allies. These results are consistent with an account in which marriages strengthened queenly reigns because married queens were more likely to secure alliances and enlist their spouses to help them rule. Married kings, in contrast, were less inclined to utilize a similar division of labor. These asymmetries, which reflected prevailing gender norms, ultimately enabled queens to pursue more aggressive war policies.
Politicians have long known to release bad news on a Friday and it appears that pharmaceutical firms may do likewise.
Safety alerts are announcements made by health regulators warning patients and doctors about new drug-related side effects. However, not all safety alerts are equally effective. We provide evidence that the day of the week on which the safety alerts are announced explains differences in safety alert impact. Specifically, we show that safety alerts announced on Fridays are less broadly diffused: they are shared 34% less on social media, mentioned in 23% to 66% fewer news articles, and are 12% to 51% less likely to receive any news coverage at all. As a consequence of this, we propose Friday alerts are less effective in reducing drug-related side effects. We find that moving a Friday alert to any other weekday would reduce all drug-related side effects by 9% to 12%, serious drug-related complications by 6% to 15%, and drug-related deaths by 22% to 36%. This problem is particularly important because Friday was the most frequent weekday for safety alert announcements from 1999 to 2016. We show that this greater prevalence of Friday alerts might not be random: firms that lobbied the U.S. Food and Drug Administration in the past are 49% to 56% more likely to have safety alerts announced on Fridays.

The Impact of the Affordable Care Act: Evidence from California’s Hospital Sector
(with Mark Duggan and Atul Gupta) R&R, AEJ: Economic Policy
The Affordable Care Act (ACA) authorized the largest expansion of public health insurance in the U.S. since the mid-1960s. We exploit ACA-induced changes in the discontinuity in coverage at age 65 using a regression discontinuity based design to examine effects of the expansion on health insurance coverage, hospital use, and patient health. We then link these changes to effects on hospital finances. We show that a substantial share of the federally-funded Medicaid expansion substituted for existing locally-funded safety net programs. Despite this offset, the expansion produced a substantial increase in hospital revenue and profitability, with larger gains for government hospitals. On the benefits side, we do not detect significant improvements in patient health, although the expansion led to substantially greater hospital and emergency room use, and a reallocation of care from public to private and better-quality hospitals.
“Engineering the gender gap: Fall of Women’s Share in Computer Science”
Download Job Market Paper (PDF)
No college major is inherently male or female. In this paper, I explore how gender traditions in the U.S influence women’s academic preferences today. I make two arguments. First, the scientific fields which involve more women today coincide with those science subjects included in home economics, an exclusively feminine field. Second, the percentage of women in computer science decreases when this major relocates to the Engineering School, a traditionally masculine domain. I argue that shaping computer science into an engineering subject has constrained women’s ability to reallocate their human capital in response to the technology shock brought by personal computers.

Why have so many young men withdrawn from the U.S. labor force since 1965? This paper presents a model in which men invest time in employment to enhance their value as marriage partners. When the marriage market return on this investment declines, young men’s employment declines as well, in preparation for a less favorable marriage market. Taking this prediction to data, I show that fewer young men sought employment after 2 interventions that reduced the value of gender-role-specialization within marriage: i) the adoption of unilateral divorce legislation, and ii) demand-driven improvements in women’s employment opportunities. I then show, using a structural estimation, that half of the employment effect of a labor market shock to men’s wages is determined by endogenous adjustment of the marriage market to the shock. These findings establish the changing marriage market as an important driver of decline in young men’s labor market involvement.

Using difference-in-difference and regression discontinuity techniques, we find that US states governed by Democrats and those by Republicans perform equally well on economic, education, crime, family, social, environmental, and health outcomes on the timeline introduced by elections (2-4 years downstream).
That is from a new paper by Adam Dynes and John B. Holbein, forthcoming in APSR.
Here is an old 2007 essay of mine from Wilson Quarterly, one which most of you have not read. The key point is that your most critical competitors are now much more distant and indeed invisible than before, and that this will have social and economic implications. Here is one excerpt:
George Shackle, the neglected Scottish economist, wrote in his 1973 book Epistemics and Economics that the entrepreneur imagines a future no one else sees. For Shackle, the entrepreneur is not just a trader, a manager, or an initiator of enterprise. The fundamental entrepreneurial activity is creative, and it occurs in the mind rather than the physical world. The creators of YouTube and Facebook did not require a new raw material or even a radically new programming technique; most of all they were blessed with the ability to imagine a new way to present material and connect people to one another. Their competitors, if that phrase can even be used, were the young potential entrepreneurs who might have hit upon similar ideas first, but didn’t. These phantom rivals were not out in the public arena, promoting their corporations or thumping their chests and proclaiming grand plans. Rather they were quietly doodling away on their computers in scattered suburbs and cities, perhaps after finishing their homework for the evening.
Invisible competition also gives an edge to people who can manage and interpret their own feedback. In the past, if you lost a job to a person who was smarter than you or had a better line of patter, you could size up the winner and gauge where you fell short. Now you can’t always see who crossed the finish line ahead of you. The future will favor people like Madonna, the pop star and media icon who has successfully reinvented herself so many times because she has an uncanny sense of where popular culture is bound and how to get there first.
The nations most disadvantaged by invisible competition may be those that exist in proximity to a key rival. They risk focusing too narrowly on one challenge and getting used to the idea that competition takes a highly visible form. Transfixed by its rivalry with India, Pakistan may be oblivious to other concerns. A similar preoccupation makes it harder for many people in the Middle East to take a global perspective.
I still like the piece.

A Theory of Criminal Justice
Abstract: I propose a general framework with which to analyze the optimal response to crime. Each criminal act, detected with some probability, generates a random piece of evidence and a consequent probability of guilt for each citizen. I consider a utilitarian planner with no artificial moral constraints. In particular, I assume no upper bound on punishment—such a bound can only rise endogenously from the utilitarian objective. I consider three types of “pure” responses—deterrence, rehabilitation, and incapacitation—along with general sentences combining any of the three. If citizens are expected utility maximizers, a repugnant conclusion is reached—it is optimal to punish only with the realization of the most incriminating evidence. Allowing for more general behavior yields a weaker but more satisfactory result—optimal punishment is always decreasing in the quality of evidence. (Rehabilitation, incapacitation, and general sentence results coming soon.)

A Theory of Experienced Utility and Utilitarianism
Abstract: I present a theory of measurement of preference intensity and use this measure as a foundation for utilitarianism. To do this, I suppose each alternative is experienced over time. An individual has preferences over such experiences. I present axioms under which preferences are represented by an experienced utility function equal to the integral of instantaneous preference intensity over time and unique up to a positive scalar. I propose an ethical postulate under which social preferences are utilitarian in experienced utilities.

In the last decade, new technologies have led to a boom in dynamic pricing. I analyze the most salient example, surge pricing in ride hailing. Using data from Uber in Houston, I build an empirical model of spatial equilibrium to measure the welfare effects of surge pricing. My model is composed of demand, supply, and a matching technology, and it allows for temporal and spatial heterogeneity, as well as randomness in supply and demand. I find that, relative to a counterfactual with uniform pricing, surge pricing increases total welfare by 3.66% of gross revenue. Only riders benefit: rider surplus increases by 6.52% of gross revenue, whereas driver surplus and Uber’s short-run profits decrease by 1.63% and 1.18% of gross revenue, respectively.
That is the topic of my latest Bloomberg column, here is one excerpt:
Second, a protest against poor conditions is not the same as a protest against inequality. Many Chilean complaints revolve around the pension system, health care, water rights, public transportation, schools and corruption. Are Chileans upset that their transport options aren’t better? That’s a complaint in absolute terms. Or are they upset that they are riding the subway while many of the wealthy have private cars with drivers? That’s a relative complaint.
The answer will depend on the protester, and in virtually all protests around the world there will be those with both motives. But some North American commentators try to equate these two grudges and subsume them all under the heading of inequality. That just won’t wash.
And don’t forget this:
In the case of Chile, it has the highest real wages in Latin America, income inequality has mostly been falling, and life expectancy is above average for the region. By Latin American standards Chile has a low rate of crime and a high degree of public order. Chile has had open and honest elections, and peaceful transfers of power, since 1990.
So high expectations may be more relevant than either “inequality” or “neo-liberalism” per se, at least for many of the protestors. There is much more of interest at the link, including some speculations as to why Chile may be different:
Another observation: Income inequality is often more galling when different economic classes encounter each other on a regular basis. So much Chilean economic and social activity is concentrated in Santiago, just as in South Korea it is in Seoul and in Singapore it is in … Singapore. In all three countries, I believe, feelings of inequality and envy are worse for that reason. By contrast, if you are a lower-middle-class person in, say, Mississippi, you may view the mansion and private plane of Bill Gates as if from a different universe.
I’ve also found Chile to have a relatively tough set of social expectations in terms of class, dress and educational background, and a relatively narrow set of expectations for women. These pressures for conformity may contribute to discontent.
