Book Description
This dissertation looks at the interaction of the legal environment with health and labor market outcomes in a variety of settings. The first chapter examines the effect of state public health insurance expansion decisions on private insurance costs by comparing how private insurance plan costs have evolved over time according to whether a state has pursued a Medicaid coverage expansion as part of the Patient Protection & Affordable Care Act. The second chapter explores how one can test for judicial ingroup biases and applies the test to workplace sex discrimination cases. The third chapter evaluates the potential efficacy of federal incentive payments designed to boost physician access to electronic health records on patient outcomes in an Emergency Department setting.

Book Description
This dissertation continues the tradition of identifying the unintended consequences of the US health insurance system. Its main contribution is to estimate the size of the distortions caused by the employer-based system and regulations intended to fix it, while using methods that are more novel and appropriate than those of previous work. Chapter 1 examines the effect of state-level health insurance mandates, which are regulations intended to expand access to health insurance. It finds that these regulations have the unintended consequence of increasing insurance premiums, and that these regulations have been responsible for 9-23% of premium increases since 1996. The main contribution of the chapter is that its results are more general than previous work, since it considers many more years of data, and it studies the employer-based plans that cover most Americans rather than the much less common individual plans. Whereas Chapter 1 estimates the effect of the average mandate on premiums, Chapter 2 focuses on a specific mandate, one that requires insurers to cover prostate cancer screenings. The focus on a single mandate allows a broader and more careful analysis that demonstrates how health policies spill over to affect the labor market. I find that the mandate has a significant negative effect on the labor market outcomes of the very group it was intended to help. The mandate expands the treatments health insurance covers for men over age 50, but by doing so it makes them more expensive to insure and employ. Employers respond to this added expense by lowering wages and hiring fewer men over age 50. According to the theoretical model put forward in the chapter, this suggests the mandate reduces total welfare. Chapter 3 shows that the employer-based health insurance system has deterred entrepreneurship. It takes advantage of the natural experiment provided by the Affordable Care Act's dependent coverage mandate, which de-linked insurance from employment for many 19-25 year olds. Difference-in-difference estimates show that the mandate increased self-employment among the treated group by 13-24%. Instrumental variables estimates show that those who actually received parental health insurance as a result of the mandate were drastically more likely to start their own business. This suggest that concerns over health insurance are a major barrier to entrepreneurship in the United States.

Book Description
This dissertation contains three chapters, two which focus on health insurance and one focusing on migration. The first chapter examines how a policy expanding public health insurance for young children affected their parents' labor market and health insurance outcomes. I use variation in the initial income thresholds, children's age cutoffs and timing of implementation across states to estimate the effect of a person's youngest child gaining access to public health insurance on self-employment. I find that having a child become Medicaid eligible increases a father's self-employment and increases his business income. I find no significant effect on self-employment for mothers, but I find that the increasing eligibility is associated with a large negative effect on their probability of remaining in a wage job. The second chapter examines how expanding dependent health insurance for young adults affects the health insurance and labor market outcomes of those young adults and their parents. I exploit two sources of variations in the age at which young adults age out of their parents' health insurance: i) state reforms passed between 2000 and 2010 that extended the maximum age of health insurance dependents beyond 18 and ii) the Affordable Care Act that extended coverage for all young adults in the United States until their 26th birthdays. Using regression discontinuity, I find evidence that the policies increased young adult dependent coverage. Dependent coverage for eligible young adults increased by 8 percentage points over ineligible young adults, while health insurance in the young adults' own name decreased by 6.5 percentage points. I also see evidence that parents of eligible young adults responded by changing their own coverage. The final chapter investigates the relationship between children and migration using data from the American Communities Survey. To address the issue that both migration and fertility might be correlated with unobserved variables I use twin births as an instrumental variable for the number of children. I find that that an additional child decreases migration by 0.6 percentage points and decreases the probability that a woman lives in her birth state by 1.4 percentage points. This suggests that more children hinder migration.

Book Description
The majority of insured Americans obtain health insurance coverage through employment as a non-portable fringe benefit. The link between health insurance coverage and employment could have potential important implica- tions on workers’ labor market decisions. My dissertation consists of three chapters that contribute to the understanding of the interaction between health insurance and workers’ job mobility. My first chapter studies the effect of the state dependent coverage man- dates on the job mobility of young adults. Prior to the Affordable Care Act, many states had already implemented insurance mandates that extended the age that young adults could gain access to parental health insurance, an alternative insurance source which is not contingent on employment. If young workers with employer-sponsored insurance (ESI) are locked into less preferred jobs for fear of losing health benefits, expanded dependent coverage is expected to reduce the job lock and increase mobility. Expanded eligibility could also decrease mobility among those who are pushed out of a better matched but uninsured job in search of access to ESI (job push). Using Survey of Income and Program Participation (SIPP) 2000-2010 data, the impact of the state mandates on job mobility is identified by a triple-difference framework that exploits the state level dependent coverage variations in eligibility criteria, mandate implementation states, and mandate implementation time. Results show that expanded dependent coverage led to a 5% decrease in the mobility of workers with no ESI (job push). I find no evidence of reduced job lock. The second chapter of my dissertation extends the analysis of my first chapter to the Affordable Care Act (ACA) Dependent Coverage Mandate. The ACA Dependent Coverage Mandate was passed on March 23rd, 2010, and became effective on September 23, 2010. The mandate requires that health insurance plans that provide dependent coverage must cover dependents until the age of 26. Using SIPP 2008-2013 data, and both difference-in-difference framework and regression discontinuity design, I find consistent evidence of reduced job push and no evidence of reduced job lock. The estimated reduced job push is larger than the state analysis. The third chapter studies the impact of the ACA Medicaid expansion on childless adults’ job mobility. The ACA Medicaid expansion raised the Medi- caid income eligibility threshold to 138% of the Federal Poverty Line (FPL) for everyone including childless adults who were not the traditional beneficiaries of the Medicaid. 32 states adopted the expansion while 19 states opted out. The reform could potentially increase childless adults’ job mobility if they are “locked” in their jobs for fear of losing employer-sponsored health insurance. Using the 2011-2016 basic monthly Current Population Survey (CPS), this paper tests this hypothesis by comparing the job mobility of childless adults in expansion states to those residing in non-expansion states, before and after the expansion. Results show the existence of “job lock” effect: the ACA Medicaid expansion increased the childless adults’ job mobility by 7% - 9%, and the increase comes entirely from job-to-job transitions. I find no evidence of the “employment lock”: the availability of Medicaid did not cause childless adults to be more likely to become unemployed or leave the labor force.

Book Description
In the United States, health insurance is often necessary for access to regular, affordable health care. With only eight of every hundred Americans buying private insurance plans on the individual market, the main sources for health insurance traditionally have been employers and the government. As new laws are being debated and introduced to reform an expensive health care industry in which nearly one-sixth of the population is uninsured, research is needed in order to evaluate the costs and benefits of these policy changes and to predict their success. To this end, in addition to understanding how likely individuals are to adopt new health insurance policies, we also should be interested in knowing how the demand for health insurance and changes in its accessibility will affect non-medical decisions. Specifically, labor market choices have been theorized to be directly related to decisions involving insurance coverage. If the availability of health insurance distorts a workers' job-related decisions, then the changing the landscape for how to access insurance may reverberate in employment outcomes. My dissertation focuses on understanding the factors that influence the demand for health insurance and the role that health insurance plays in an individual's decision to work, where to work, and how much to work. Specifically, I focus on the following three related questions: how does the demand for insurance affect labor market decisions such as when to exit unemployment? what drives insurance demand, and in particular, what motivators work best to increase demand for health coverage among the uninsured? and lastly, what are the supply-side employment responses to the provision of free or reduced-cost public health insurance? My first chapter explores how the demand for health insurance can change re-employment decisions among the unemployed, as well as the speed at which individuals return to work. Past research on this issue focuses on job-to-job switches and "job lock" but has yet to focus on individuals looking for work. This chapter uses data on laid-off individuals from the Medical Expenditure Panel Survey to compare the job search behavior and outcomes of individuals who differ in their demand for health insurance. I use three proxies for demand, based on spousal health and past insurance offer take-up decisions. Although each is potentially confounded by unobserved determinants of job search, I use a difference-in-differences and propensity score designs to isolate plausibly causal effects. I find consistent patterns across all three proxies (despite different potential omitted variables biases). Overall unemployment durations do not vary with demand for insurance, but this masks variation in the types of jobs taken. Individuals with higher demand for insurance have higher hazards for exiting unemployment into a job with insurance, but lower hazards for exiting to a job without insurance. This points to effects of insurance demand on both search effort and reservation wages, and to potentially important distorting effects of employer-linked health insurance. Whereas the first chapter takes variation in demand for insurance as a given, my second chapter digs deeper into the basis for this variation and whether it can be affected. In this chapter, I investigate the reasons the uninsured choose to forego insurance coverage and the impact of different messages on their insurance demand. Working with Enroll America, a large non-profit dedicated to decreasing the number of uninsured Americans, I conducted a stratified experiment to determine the best communication strategies to encourage participation in the healthcare exchanges. We test a combination of the following behavioral and information treatments: a risk treatment that emphasizes the average financial risk for someone without health insurance; a norms treatment that alerts our participants that staying uninsured will be against the law; a savings treatment that highlights the average savings available at the exchanges; a wording treatment where we refer to the Affordable Care Act (ACA) as "Obamacare"; and lastly, a cost-calculator treatment that allows individuals to explore the likely cost of insurance based on their own characteristics. Among the uninsured, we find that the cost-calculator treatment, the risk treatment, and the mandate are most effective in increasing intention to purchase insurance. The cost-calculator and the risk treatment increase informedness among this population, but the cost-calculator (when paired with the savings treatment) is the only treatment that increases willingness to pay for insurance. We use the information on willingness to pay to construct sub-group price elasticities of demand to compare to previous work interested in the demand for health insurance. Overall, the results of this chapter highlight the importance of informational campaigns to increase awareness of the costs and benefits of health coverage, particularly after large changes such as those implemented by the ACA. My third chapter continues by looking at the changes that have been introduced as a result of the ACA. Specifically, it explores whether expanding access to government-provided insurance affects individuals' decisions regarding employment and overall hours of work. Recent findings have suggested that increasing access to health insurance outside of employment has a sizable, negative impact on labor force participation. Along these lines, the Congressional Budget Office predicted that the expansion of Medicaid and private health insurance will cause a 1.5 to 2% reduction in hours worked in the first ten years. Comparing states by whether they chose to expand Medicaid under reforms introduced by the ACA, I look at changes in the probability a childless adult receives Medicaid, as well as changes in this group's employment likelihood and hours of work. Using household survey data from the CPS monthly survey and ASEC Supplement, I confirm a marked increase in the percent of childless adults insured by Medicaid but find no statistically significant changes in employment outcomes. I compare these results to other estimates of "employment lock" in recent literature. These results, though imprecise, align with the findings in Chapter 1 which suggest that overall employment is not drastically affected by insurance demand.

Book Description
The two chapters of my dissertation develop and estimate economic models to analyze the demand for and the provision of health care services. Specifically, I analyze the optimal design of health care markets to promote higher quality and lower cost, which can have profound implications for the well-being of people. The first chapter, "An Equilibrium Analysis of the Long-Term Care Insurance Market," uses a model of family interactions to explain why the long-term care insurance market has not been growing. By developing and estimating a structural model of family interactions, I study how family care affects the workings of the long-term care insurance market. I argue that private information about the availability of family care induces adverse selection where individuals with limited access to family care heavily select into insurance coverage. I demonstrate that pricing on family demographics substantially mitigates adverse selection by reducing the amounts of private information. I propose child demographic-based pricing as an alternative risk adjustment that could decrease the average premium, invigorate the market, and generate welfare gains. The second chapter, "Partial Rating Area Offering in the ACA Marketplaces," joint with Hanming Fang, studies insurance companies' plan offering decisions in the marketplaces established by the Patient Protection and Affordable Care Act of 2010 (ACA). Under the ACA, insurance companies can vary premiums by "rating areas" which usually consist of multiple counties. In a given rating area, the ACA mandates uniform pricing for all counties, but, it does not mandate universal offering. We first demonstrate that it is not uncommon to observe insurance companies selling plans to only a subset of counties within a rating area. Using both theoretical and empirical approaches, we find evidence that partial rating area coverage is explained by insurers' incentive to risk screen consumers. While the ACA allows price discrimination based on rating areas and not on counties, we argue that insurers are effectively price discriminating consumers based on counties by endogenously determining their service area within a rating area.

Book Description
Abstract: Health care systems are complex organizations. Multiple agents interact in different settings to provide health care, each one of them with different objectives and information. How markets are organized and which actions are allowed, has a direct impact on the incentives agents face when making health care choices. In this dissertation, I study the determinants and effects of these choices on market outcomes, focusing on private health insurance markets. The first chapter provides insights about health insurance markets in which workers, rather than firms, choose insurance plans in an imperfect competition setting. Using a unique dataset that includes every person enrolled in private plans in Chile in 2009, I estimate underlying preference parameters over health insurance features. I find large heterogeneity in the valuation of these features across age-sex-groups and individual types. Individual characteristics play an important role on health plan choices and therefore, can be used by insurers to design plans targeted to specific groups and for patient selection. The second chapter presents a theoretical model where private insurers compete with a free public alternative to attract clients. Using a two-type model I show that if private insurance companies offer a non-rationing alternative and the public system rationing is done through random selection, an efficiency trap may exist. A marginal increase in the budget allocated to the public system can potentially reduce the expected welfare for all types. This result extends to a model with multiple types, but the negative welfare impact is offset by a crowding-in effect among the rich. Finally, the third chapter provides a general analytical framework that can be used to evaluate risk selection under different health care models. The model is based on the interactions between the four key agents present in every health care system: sponsors, health plans, providers and customers. This framework is used to review risk selection in four countries in the Americas -Canada, Chile, Colombia, and the U.S.-, showing how regulatory policies both create and ameliorate it, and in some cases are as important as risk adjustment, risk sharing and risk selection strategies for reducing risk selection.

Book Description
Addressing the challenge of covering heath care expenses—while minimizing economic risks. Moral hazard—the tendency to change behavior when the cost of that behavior will be borne by others—is a particularly tricky question when considering health care. Kenneth J. Arrow’s seminal 1963 paper on this topic (included in this volume) was one of the first to explore the implication of moral hazard for health care, and Amy Finkelstein—recognized as one of the world’s foremost experts on the topic—here examines this issue in the context of contemporary American health care policy. Drawing on research from both the original RAND Health Insurance Experiment and her own research, including a 2008 Health Insurance Experiment in Oregon, Finkelstein presents compelling evidence that health insurance does indeed affect medical spending and encourages policy solutions that acknowledge and account for this. The volume also features commentaries and insights from other renowned economists, including an introduction by Joseph P. Newhouse that provides context for the discussion, a commentary from Jonathan Gruber that considers provider-side moral hazard, and reflections from Joseph E. Stiglitz and Kenneth J. Arrow. “Reads like a fireside chat among a group of distinguished, articulate health economists.” —Choice

Book Description
A distinctive feature of the health insurance market in the U.S. is the restriction of group insurance availability to the workplace. This has a number of important implications for the functioning of the labor market, through mobility from job-to-job or in and out of the labor force, wage determination, and hiring decisions. This paper reviews the large literature that has emerged in recent years to assess the impact of health insurance on the labor market. I begin with an overview of the institutional details relevant to assessing the interaction of health insurance and the labor market. I then present a theoretical overview of the effects of health insurance on mobility and wage/employment determination. I critically review the empirical literature on these topics, focusing in particular on the methodological issues that have been raised, and highlighting the unanswered questions which can be the focus of future work in this area.
