Use of public assistance by noncitizens is controversial. Before 2018, institutionalization and receipt of cash benefits were considered as evidence of whether immigrants were likely to become a "public charge" and, therefore, ineligible for citizenship. But a new rule-proposed in 2018 and...

Standard estimates based on the main household survey used to shed light on labor markets -the Current Population Survey (CPS)- suggest that after a significant drop during the pandemic, recent rapid growth has brought the foreign-born population back to, or above, levels predicted by the...

The Covid-19 pandemic has accelerated trends in automation as many employers seek to save on labor costs amid widespread illness, increased worker leverage, and market pressures to onshore supply chains. While existing research has explored how automation may displace nonspecialized jobs, there...

We present a cooking technology consisting of a solar panel directly connected to an electric heater inside of a well-insulated chamber. Assuming continued decrease in solar panel prices, we anticipate that in a few decades Solar Electric Cooking (SEC) technologies will be the most common...

In Fall 2014, Wellesley College began mandating pass/fail grading for courses taken by first-year, first-semester students, although instructors continued to record letter grades. We identify the causal effect of the policy on course choice and performance, using a...

Many observers argue that diversity in Economics and STEM fields is critical, not simply because of egalitarian goals, but because who is in a field may shape what is studied by it. If increasing the rate of majoring in mathematically-intensive fields among women is a worthy goal, then...

We use the Longitudinal Business Database to examine the impact of state-level paid parental leave laws in California, New Jersey, and Rhode Island on firms. Our main estimation strategy uses multi-unit firms and compares within-firm changes in outcomes for establishments in treated and...

Immigrants to the United States tend to have characteristics in common with native-born populations that are disproportionately incarcerated. The perception that immigration adversely affects crime rates led to legislation in the 1990s that particularly increased punishment of criminal aliens....

This paper studies semiparametric versions of the classical sample selection model (Heckman (1976, 1979)) without exclusion restrictions. We extend the analysis in Honor'e and Hu (2020) by allowing for parameter heterogeneity and derive implications of this model. We also consider models that...

Two of Peter Schmidt's many contributions to econometrics have been to introduce a simultaneous logit model for bivariate binary outcomes and to study estimation of dynamic linear fixed effects panel data models using short panels. In this paper, we study a dynamic panel data version of the...
