“Effects of Legal Same-Sex Marriage on Employer Offers of Domestic Partner Health Benefits”
Ben Harrell ( with Christopher S. Carpenter and Thomas Hegland

Abstract: Research has demonstrated that legal access to same-sex marriage in the United States – which was granted by a 2015 Supreme Court decision in Obergefell v. Hodges – increased health insurance coverage and access to care among same-sex couples, possibly through a partner’s employer. Many observers noted, however, that firms might stop offering insurance benefits for unmarried partners of employees in the presence of full nationwide marriage equality. No prior research has studied these questions due to lack of employer data. We fill this gap and provide the first evidence on same-sex marriage and employer choices about health insurance benefits by using rich confidential establishment level microdata from the 2013-19 Medical Expenditure Panel Survey – Insurance Component (MEPS-IC). We find clear evidence that although firms were much more likely to offer insurance coverage to unmarried same-sex partners compared to unmarried different-sex partners of employees prior to 2015, firms responded to nationwide marriage equality by significantly reducing insurance offers for unmarried same-sex partners. These reductions in same-sex partner benefits: are exactly coincident with the Obergefell decision, are sustained through 2019, are not observed for unmarried different-sex partner benefits nor for other unrelated benefits such as dental or vision coverage and are unique to the private sector. Notably, these effects are invariant to whether the establishment is located in a state that had already legalized same-sex marriage prior to Obergefell (and thus for whom the decision was less of a treatment), suggesting that firm decisions regarding same-sex partner benefits respond to changes in broader national norms as opposed to the specific local or state policy environment in which the firm operates, consistent with our core findings being driven by large multi-establishment firms with workers in many states.

“Public Health Insurance Expansions and The Spread of Infectious Disease”
Shyam Raman ( with Katherine Wen, Ben Harrell, Sam Mann, and Alex Hollingsworth

Abstract: We investigate the effects of the Affordable Care Act (ACA) facilitated Medicaid expansions on the use of pre-exposure prophylaxis (PrEP) for HIV. In administrative data from 2011 to 2019, we identify medications prescribed for PrEP and exploit state-level variations in Medicaid expansion to evaluate their effect on PrEP utilization. Using an event study specification in a two-way fixed effects (TWFE) setting, we estimate the impact of these expansions on PrEP prescriptions, HIV diagnoses, and common sexually transmitted infections. Following recent work, we employ methods which attempt to address the potential for bias arising due to the staggered timing of Medicaid expansions. We find a 70% increase in the utilization of PrEP within the Medicaid population for states which expanded Medicaid compared to those which did not. Additionally, we find a 5% reduction in HIV diagnoses among men and a 9% reduction in HIV diagnoses in ages 25-34. Our results offer evidence that suggests increased access to healthcare increases utilization of drugs which greatly reduce the risk of HIV and has the potential to reduce the spread of HIV.

“Intergenerational Mobility of LGBTQ+ Individuals”
Santiago Deambrosi (

Abstract: I study the intergenerational mobility of LGBTQ+ individuals in their 20's by comparing how the income and education of parents and their offspring are related---and then drawing distinctions between correlations of queer and non-queer pairs. Recently-released PSID data allows me to identify LGBTQ+ individuals without having to draw assumptions based on marriage (n=300+). I provide further insights on the `queer' experience through Sibling Correlation and Equality of Opportunity approaches, using a rich set of cognitive and behavioral data that also includes information on parent-child relationships, differential treatment and investment, parental gender norms, self-perceived discrimination, and more. Finally, I try to compare the intergenerational mobility rates of two adjacent queer generations to sense whether the rapid advancements in LGBTQ+ civil rights, healthcare, and acceptance are reflected on economic opportunity at young stages of life.

Matching on Gender and Sexual Orientation
Edoardo Ciscato and Marion Goussé (

Abstract: In this paper, we consider a matching model of marriage with endogenous selection of partner gender. We use U.S. and German data on couples and singles that includes a measure of sexual orientation. We first document substantial heterogeneity in sexual orientation across gender and couple types. First, we find that more women report being attracted to both genders than men, whereas more men report being attracted only to one gender. Second, we document that the vast majority of bisexuals are in a relationship with a person of the opposite gender, while a non-negligible share of gay men and lesbian women are in fact in a relationship with someone of a different gender. We therefore observe a discrepancy between the gender of the partner that is preferred and the gender that is actually chosen. We then estimate a multidimensional matching model of the marriage market that includes gender, sexual orientation, age, education, and race and show and quantify the potential trade-offs between gender and certain partner characteristics when choosing a spouse. In a series of comparative statics exercises, we quantify the change in the share of same-sex couples in response to demographic changes, such as an imbalance in the gender ratio.

Commuting to work and gender-conforming social norms: evidence from same-sex couples
Sonia Oreffice ( ) and Dario Sansone

Abstract: We analyze work commute time by sexual orientation of partnered or married individuals, using the American Community Survey 2008-2019. Women in same-sex couples have a longer commute to work than working women in different-sex couples, whereas the commute to work of men in same-sex couples is shorter than the one of working men in different-sex couples, also after controlling for demographic characteristics, partner’s characteristics, location, fertility, and marital status. These differences are particularly stark among married couples with children: on average, about 3 minutes more one-way to work for married mothers in same-sex couples, and almost 2 minutes less for married fathers in same-sex couples, than their corresponding working parents in different-sex couples. These gaps among men and women amount to 50%, and 100%, respectively, of the gender commuting gap estimated in the literature. Within-couple gaps in commuting time are also significantly smaller in same-sex couples. We interpret these differences as evidence that it is gender-conforming social norms boosted by parenthood that lead women in different-sex couples to specialize into jobs with a shorter commute while their male partners/spouses hold jobs with a longer commute.

Do LGBTQ-related Events Drive Individual Online Disclosure Decisions?
Jason Jones (

Abstract: When and how to come out are difficult choices. In this research project, we examine one form of disclosure: the addition of an LGBTQ keyword to one's online social media profile. We construct daily time series of the prevalence of American Twitter users whose self-descriptions contain LGBTQ keywords. Further, we construct daily time series of inferred add and delete events - i.e. we make best estimates for how many users per day make an edit to include a previously absent word or remove a word previously present. These we compare to relevant annual and one-time events such as LGBTQ Pride Month and the date of the Pulse Nightclub shooting. We confirm one pre-registered hypothesis and explore several others.
