How does policy influence the utilization, finances, and prices of hospitals in the United States? This dissertation addresses this question through three essays that employ a variety of quantitative methodologies and data sources. Using a regression discontinuity design and all-payer claims data from Colorado, Chapter...

“Entre futuros” reimagines the fixed border on the Río Bravo between Ciudad Juárez, Chihuahua, and El Paso, Texas. As the river shifted course, land disputes led to channelization, leaving hundreds of cut-off meanders since the 1930s as “hydroghosts”—scars in both landscape and lived experience. These traces become a l...

Let $\lambda$ and $\mu$ be partitions, and let $n = |\mu|$. A fundamental open problem in algebraic combinatorics is to determine the \emph{restriction coefficients} $r_\lambda^\mu = \dim \operatorname{Hom}_{\Sym_n}(V_\mu, \mathbb{S}^\lambda \mathbb{C}^n)$, where $V_\mu$ is the Specht module indexed by $\mu$ and $\math...

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy that is one of the most treatment-resistant forms of cancer. Genomic studies of PDAC have demonstrated profound transcriptional cell state heterogeneity within both primary and metastatic PDAC tumors. Moreover, preclinical experiments and recent...

Simulation algorithms have become increasingly popular in solving apportionment problems in political redistricting, but they are largely untapped in the practice of designing school boundary maps. Many school districts have initiated processes to modernize attendance area boundaries, which determine school assignments...

Ultracold polyatomic molecules containing heavy nuclei, such as SrOH and YbOH, are sensitive to T- symmetry violating and P-symmetry violating physics beyond the Standard Model through the electron’s electric dipole moment. Furthermore, SrOH is sensitive to ultralight Dark Matter through measuring time variations of fu...

This dissertation presents three essays in development economics that address the relationship between social exclusion and poverty. Chapter one asks: What are the causal effects of new social relationships, and do returns to link formation vary within versus across social class? I conduct a field experiment among wome...

Evaluating the effectiveness of educational interventions presents two distinct challenges: measurement of outcome variables through psychometrics and estimation of program impact through causal inference techniques. Education research has been unnecessarily constrained by the separation of these two domains, and their...
