This dissertation focuses on two topics in international macroeconomics: the identification of the international spillovers of US interest rate shocks, and the study of its main transmission channels. In Chapter 1, I present the Spillover Puzzle of US Monetary Policy - the fact that in response to a US interest...
Chapter 1 investigates asks the question how do financial frictions affect the type of human capital investments that students make in college? To study this question, I build a novel dataset covering more than 700,000 U.S. students, merging commencement records with address histories, credit bureau records, and professional resumes. I...
From daily hygiene habits, such as brushing teeth, to the ingestion of pharmaceuticals, many forms of healthcare are commonly practiced in daily life, at home. How have household healthcare practices changed over time in urban America? Taking Washington, DC as my case study, I examine patterns of household pharmaceuticals access...
This dissertation aims to understand how Black Chicagoans work with institutions and neighbors they distrust to pursue common policy goals – in this case, to remedy state and community violence. I introduce the theory of distrustful cooperation. Using three Chicago neighborhoods as cased studies: Greater Englewood, Bronzeville, and Calumet Heights,...
Motor abnormalities (e.g., dyskinesia, psychomotor slowing, neurological soft signs) are core features of schizophrenia observed from the premorbid period through chronic illness, suggesting motor dysfunction may reflect the pathophysiology of psychosis. Among this list of motor abnormalities, psychomotor slowing in particular is one of the most consistently observed and robust...
Atomistic methods offer a powerful set of tools in the study of materials systems, as they allow materials scientists to ask questions with a high degree of specificity. They are well suited for studying and designing energy materials, critical due to the climate crisis, in part due to their ability...
The importance of understanding indoor microbial exposure is increasingly recognized, particularly concerning the emergence of pathogens and antimicrobial resistance. With the advancements of sequencing technologies, our capability of exploring indoor microbial communities has dramatically increased. However, huge challenges remain to translate sequence-based knowledge to actionable interpretations to support human health...
Every music theorist has their own personal reasons for engaging in the craft of theorizing about music. Many discover that there is something special about a theoretic disposition which differs from other sorts of interactions with music. It is often this special something that draws musicians into the discipline: specifically,...
This dissertation explores the economics of health and housing policies. In the first chapter, I discuss information disclosure policies in healthcare. Information disclosure programs can help consumers make better choices, but the consumers who respond the most to the information may not benefit the most or generate the most savings...
Heteroanionic materials are a class of materials of interest for their unique and tunable electronic, ionic, thermal, and optical properties, which are distinct from their homoanionic counterparts due to their multi-anionic nature. Oxynitrides, a type of heteroanionic material, are useful catalysts due to the effect of mixing oxygen and nitrogen...
Astronomy has entered a “multimessenger” era: one that combines electromagnetic “sight” with gravitational “touch.” This dissertation serves as a roadmap of the multimessenger frontier, to join the littered environments of dead and dying starswith their unclear origins. To uncover stars’ innermost secrets, we explore rare, transient glimpses into single, double,...
Very few studies have examined school racial climate in racially diverse school contexts. School racial climate refers to “perceptions of interracial interactions and the socialization around race and culture in a school” (Byrd, 2017, p. 700). The association between interracial peer interactions, psychological well-being, and academic outcomes is well documented,...
This dissertation comprises three essays in distinct areas of economic theory, yet all are related to experimentation and learning. In the first chapter, I study how organizations assign tasks to identify the best candidate to promote among a pool of workers. Task allocation and workers’ motivation interact through the organization’s...
Systems of accountability for police who violate the U.S. Constitution are broken. Among other mechanisms of accountability, the judicial system should provide a path for victims to obtain a remedy when their constitutional rights are violated. Yet unless the law is clearly established beyond debate, the doctrine of qualified immunity...
Bio-integrated electronics with advanced monitoring capabilities have garnered considerable interest as a means of expanding patient care beyond traditional hospital and clinic settings. These mechanically soft microsystems, many of which are bioresorbable and wireless, have the potential to replace bulky, rigid, and wired medical technologies by matching or exceeding their...
This dissertation explores accounting information's role in forming R\&D alliances and subsequent innovation. Specifically, I utilize the effect of the recent revenue recognition rule change, Accounting Standard Codification (ASC) 606, on drug development firms. ASC 606 allows managers to change revenue recognition timing and increases disclosure requirements. I first document...
``Hazy decisions: The effect of dementia on medical decision-making'' \\ I estimate the causal effect of having dementia on the course of treatment for unrelated diseases by leveraging differences in the relative time of onset of dementia and the other condition in a difference-in-differences event-study framework. To demonstrate this approach...
Lithium-ion battery technology is a critically important component of the emerging renewable energy infrastructure. Since battery technology was first commercialized in the 1990s, significant progress has been made in materials development, motivated by the prospect of higher energy and power densities, increased cycling longevity, and faster charging and discharging rates....
Every day, we communicate through computers on projects ranging from a group lunch order to booking a flight to learning critical medical information. And every day, we also miscommunicate through computers: We don’t pick up on an intentionally humorous response, or we miss the criticality of a request. This is...
SCN2A encodes the NaV1.2 voltage-gated sodium channel, which is thought to contribute to the development of the central nervous system. Pathogenic variants in SCN2A have been associated with neurodevelopmental disorders (NDD), including developmental and epileptic encephalopathies (DEE), intellectual disability (ID), and autism spectrum disorder (ASD). These disorders represent a significant...
