Stanford University

I am an economist in year 3 of a 5-year research fellowship at Stanford University's Hoover Institution. I work on topics across public and labor economics, often forming research partnerships with government agencies to improve public services and gain insight into social behavior.

I received a PhD in Economics from Harvard University and a BA in Economics and International Relations from Stanford University.

The State of Mental Health in European Economics Departments

We study the mental health of graduate students and faculty at 14 Economics PhD programs in Europe. Using clinically validated surveys sent out in the fall of 2021, the second year of the COVID-19 pandemic, we find that 34.7% of graduate students experience moderate to severe symptoms of depression or anxiety and 17.3% report suicidal or self-harm ideation in a two-week period. A U.S. study done in 2017 across 8 top-ranked departments found the prevalence rates to be 24.8% and 11.3%, respectively. Only 19.2% of students with significant symptoms are in treatment, compared to 25.2% of students in the U.S. study. Among faculty, 15.8% experience moderate to severe depression or anxiety symptoms (31.4% among untenured, tenure-track faculty).

A Blueprint for Measuring and Improving Graduate Student Mental Health

We provide a step-by-step guide for developing, administering, evaluating, and acting on a survey-based study of graduate student mental health. Blueprint focuses on forging student-faculty collaboration and is based on Harvard University’s Graduate Student Mental Health Initiative (GSMHI). The survey tool we use includes validated screening instruments for depression, anxiety, imposter phenomenon, self-esteem, alcohol consumption, exercise and sleep habits, and loneliness. It also includes environmental questions that collect epidemiologic data, as well as ratings of advising relationships and student dynamics. After 6 years, GSMHI has analyzed data from 30 different PhD programs and 4,866 students, overseen the implementation of more than 60 departmental action plans, and performed 9 follow-up surveys to assess progress. It has achieved high response rates (60–90%), discovered wide variation in mental health and environmental factors across departments, and supported experiments with interventions. We hope this blueprint helps other universities run similar initiatives.

Heat, Crime, and Punishment

Using administrative criminal records from Texas, we show how heat affects criminal defendants, police officers, prosecutors, and judges. We find that arrests increase by up to 15% on hot days, driven by increases in violent crime. We see no evidence that charging-day heat impacts prosecutorial decisions. However, working alone, judges dismiss fewer cases, issue longer prison sentences, and levy higher fines when ruling on hot days. Higher incomes, newer housing, more teamwork, and less accessible weapons may decrease the adverse effects of heat. Even with adaptation, we forecast that climate change will increase crime and have substantial distributional consequences.

Immigrant Intergenerational Mobility: A Focus on Childhood Environment

Over 60% of immigrant parents in Sweden start off in the bottom quintile of the income distribution, yet only about 30% of their children are still in the bottom income quintile in adulthood. This progress notwithstanding, we show using administrative data that immigrant children who grow up in the 20th income percentile place three income ranks lower than native children of similarly low-income parents. This income gap cannot be explained by differences in parent education levels, family structure, or municipality of residence. The gap can, however, be explained by differences in immediate, 100 × 100 - meter neighborhoods. Immigrant children grow up in relatively denser neighborhoods with fewer native-born and high-earning neighbors. Data from Stockholm suggest that immigrant families sort into different neighborhoods than natives due to Sweden’s rental housing allocation mechanism that is based on waiting time rather than market rents.

Why Do Women Earn Less Than Men? Evidence from Bus and Train Operators

Female workers earn $0.89 for each male-worker dollar even in a unionized workplace where tasks, wages, and promotion schedules are identical for men and women by design. Using administrative time-card data on bus and train operators, we show that this earnings gap can be explained by female operators taking fewer hours of overtime and more hours of unpaid time-off than male operators. Female operators, especially those with dependents, pursue schedule conventionality, predictability, and controllability more than male operators. We demonstrate that while reducing schedule controllability can limit the earnings gap, it can also hurt female workers and their productivity.

Other Projects

Counting on Coronavirus Luck is Not a Fall Election Strategy. Best Bet is Vote by Mail.

Op-ed with Larry Diamond. May 4th, 2020. Vote by mail is not a partisan plot, it's critical infrastructure to assure a safe election in a pandemic. Now is the time to invest and prepare.

The Immigrant Doctors Project

The Immigrant Doctors Project is an effort by (former) Harvard and MIT Economics PhD students to highlight the areas of the United States that rely most heavily on immigrant doctors from Iran, Libya, Somalia, Sudan, Syria, and Yemen.

To Address Collegiate Mental Health, Start with Vaccine Mandates and In-Person Classes

Op-ed with Paul Barreira. August 5th, 2021. Changing culture around mental health will mean envisioning college as a space where academic excellence is closely intertwined with meaningful social relationships and thriving mental health.
