Title: Divorce Expectation, Human Capital, and Life Cycle of Female Labor Supply

Abstract: There is a puzzle in economics and sociology that Black women have a higher labor supply than white women in the US. This paper shows the gap is driven by married Black women with high wages returning to work quickly after childbirth. I develop a life cycle model of female labor supply, human capital, consumption, and savings with marriage uncertainty. The structural model demonstrates that Black women stay in the workforce to maintain human capital and hedge against marital instability. Furthermore, this paper shows structural estimates of human capital depreciation in the labor literature are likely biased without sample selection correction for exclusive restriction.

Title: Minimum Wage, Marriage, and Fertility

Abstract: Exploiting state-varying minimum wage in the US from 1975 to 2016, this paper shows the causal effect of minimum wage on marriage, divorce, and fertility. An increase in state minimum wage by 1 dollar significantly increases the marriage rate by 0.6 percentage points, reduces the divorce rate by 0.4 percentage points, and increases the fertility rate by 0.5 percentage points. I develop an equilibrium life cycle model of marriage, fertility, labor supply, and consumption to decompose the causal effects by complementarity in leisure time among partners, and substitutability in child production. This paper demonstrates that labor market policy has significant spillovers on the marriage market.

Title: Enhancing Learning Through Group Work: Challenges and Strategies

Abstract: Group work is a powerful pedagogical tool that promotes active learning, collaboration, and critical thinking skills among students. This seminar explores some effective strategies for implementing group work in educational settings along with the challenges associated with integrating group work into formative and summative assessments.

Title: Dealing with Adversity: Religiosity or Science? Evidence from the Great Influenza Pandemic, co-authored with E.Berkes, D.Coluccia, and G Dossi.
Abstract: How do societies respond to adversity? After a negative shock, separate strands of research document either an increase in religiosity or a boost in innovation efforts. In this paper, we show that both reactions can occur at the same time, driven by different individuals within society. The setting of our study is the 1918–1919 influenza pandemic in the United States. To measure religiosity, we construct a novel indicator based on naming patterns of newborns. We measure innovation through the universe of granted patents. Exploiting plausibly exogenous county-level variation in exposure to the pandemic, we provide evidence that more-affected counties become both more religious and more innovative. Looking within counties, we uncover heterogeneous responses: individuals from more religious backgrounds further embrace religion, while those from less religious backgrounds become more likely to choose a scientific occupation. Facing adversity widens the distance in religiosity between science-oriented individuals and the rest of the population, and it increases the polarization of religious beliefs.

Title: Testing Inequalities Linear in Nuisance Parameters (with Gregory Cox and Yuya Shimizu) at the econometrics seminar.

 Abstract- This paper proposes a new test for inequalities that are linear in possibly partially

identified nuisance parameters, called the generalized conditional chi-squared (GCC)

test. It extends the subvector conditional chi-squared (sCC) test in Cox and Shi (2023,

CS23) to a setting where the nuisance parameter is pre-multiplied by an unknown

and estimable matrix of coefficients. Properly accounting for the estimation noise in

this matrix while maintaining the simplicity of the sCC test is the main innovation

of this paper. [How? New variance formula? Rank condition?] As such, the paper

provides a simple solution to a broad set of problems including subvector inference for

models represented by linear programs, nonparametric instrumental variable models

with discrete regressor and instruments, and linear unconditional moment inequality

models. We also derive a simplified formula for computing the critical value that makes

the computation of the GCC test elementary.
