Expanding Public Health Insurance To Parents: Effect On Parents' And Children’S Well-Being, Michelle Marcus, Xuan Zhang

Research Collection School Of Economics

Expanding public health insurance to parents may not only improve parental outcomes but also have spillover effects on their children. This paper leverages the natural experiment of the Affordable Care Act (ACA) to estimate the causal effects of expanding public health insurance to low-income parents on their well-being and that of their children. Using a difference-in-differences model and data from the 2010–2017 National Health Interview Surveys, we observe significant improvements in health care access, increased health care utilization, reduced financial burdens, and slight improvements in health status among low-income parents. For children in Medicaid expansion states, we find reductions in …

Retroactive Eligibility Waivers: Innovative Or Ineffective?, Mohamed Kacem Benyamine

Theses and Dissertations

Medicaid’s retroactive eligibility provision covers medical expenses for beneficiaries up to 90 days before the application date. Retroactive eligibility insulates uninsured, low-income households from expensive healthcare emergencies. New Hampshire, Arkansas, and Iowa recently obtained waivers to end retroactive coverage. Using a difference-in-differences design and data from the Behavioral Risk Factor Surveillance System, I evaluate whether changes in retroactive coverage affect enrollment rates and self-reported health. Removing retroactive eligibility has no statistically significant effects on insurance enrollment or self-reported health. However, it does increase rates of access to a doctor by 1.0% overall and by 1.6% for women. Removing retroactive eligibility …

The Effect Of The Affordable Care Act Medicaid Expansion On The Risk Of Hospital Closure And Adolescent Hpv Immunization In Rural Counties, Juliette Des Rosiers

Scripps Senior Theses

From 2005 to 2025, over 200 rural hospitals shut their doors, often citing increased operational costs, staffing shortages, low patient volume, regulatory barriers, financial challenges exacerbated by the COVID-19 pandemic, and uncompensated care as common contributors to the closures. Rural patients are often referred by their primary care physician to a hospital for regular immunizations, since smaller clinics have less capacity to provide immunizations due to a shortage of pediatricians and limited vaccine stock. A crucial vaccine that is not required by schools and underutilized in rural areas is that against human papillomavirus (HPV), a virus that infects cutaneous and …

Assessing The Impact Of Medicaid Expansion On The Labor Market, Healthcare Access, And Health Outcomes During The Covid-19 Pandemic, Kaavya Narayan

CMC Senior Theses

This thesis examines the impact of Medicaid expansion status on labor market outcomes, healthcare access, and health outcomes during COVID-19. Using data from the CDC’s Behavioral Risk Factor Surveillance System and a Difference-in-Differences (DiD) model, I estimate the effects of Medicaid expansion on unemployment, financial barriers to care, obesity, and poor health before and after the pandemic. The analysis also accounts for state-level political and demographic characteristics, gender, marital status, and education level. My results show that non-expansion states, relative to expansion states of similar political and demographic breakdowns, are significantly more disadvantaged in terms of obesity, poor health, financial …

The Effect Of The Affordable Care Act On Opioid Overdose Mortality, Caleb Jordan

All Theses

The opioid epidemic is an ongoing health crisis in the United States, claiming the lives of thousands over the past two decades. In 2014, provisions of the Affordable Care Act expanding Medicaid officially came in effect, extending healthcare to millions of people in the United States. However, Medicaid expansion was optional for states, so some states greatly expanded healthcare to low-income people while others did not. People in expansion states gained more affordable access to prescription drugs and treatment centers, making opioids easier to obtain and addictions more affordable to treat. This makes the effect of the Affordable Care Act …

Political, Racial, And Household Income Barriers For Access To Healthcare In Illinois Counties, Kennedy Bray '23

Student Publications & Research

Access to health care impacts many people throughout the United States, as it restricts their ability to solve their health concerns. People who have the highest risk of a lack of access include people who are uninsured, people a part of a specific social class, or people belonging to a specific political party. In a particular geographical region, these factors could lead to groups of people suffering because of circumstances that they cannot control in their region. In my project, I determine how better access to healthcare and the percentage of people insured are affected by a measurement of the …

An Analysis Of The 2014 Medicaid Expansion On New York And California's Maternal Mortality Rate, Reshanna Jagroo

Honors Undergraduate Theses

This thesis seeks to investigate the 2014 Medicaid expansion’s effect on maternal mortality rates for New York and California. The CDC reported in 2019 that maternal mortality rates have been increasing. These findings are concerning for mothers and are a problem for developed nations like the United States with improved healthcare. Furthermore, women of color are disproportionately affected relative to white women. Previous research has indicated that healthcare expansions positively affect decreasing death rates among pregnant women.

In this study, I investigate how increased access to healthcare through the 2014 Medicaid expansion under the Affordable Care Act affects maternal mortality …

The Full Impact Of The Affordable Care Act On Political Participation, Charles J. Courtemanche, James Marton, Aaron Yelowitz

Economics Faculty Publications

This article examines the impact of both the Medicaid expansion and the private insurance-related components of the Affordable Care Act (ACA) on voter turnout and registration. We employ a difference-in-difference-in-differences identification strategy exploiting variation over time, state Medicaid expansion status, and within-state local area pre-ACA uninsured rates. Using data between 2006 and 2016 from the November Current Population Survey and the Census Bureau's Small Area Health Insurance Estimates, our results suggest little effect of the ACA on voter turnout or registration.

Medical Resource Use And Costs Of Treating Sickle Cell-Related Vaso-Occlusive Crisis Episodes: A Retrospective Claims Study, Nirmish Shah, Menaka Bhor, Lin Xie, Jincy Paulose, Huseyin Yuce

Publications and Research

Background: The study investigated the economic burden of vaso-occlusive crisis (VOC) among sickle cell disease (SCD) patients, through assessment of overall utilization and costs and costs per VOC episode (regarding the number of VOC episodes and health care setting, respectively).

Methods: Using the Medicaid Analytic Extracts database, the first SCD-related diagnosis claim (index claim) between June 1, 2009–December 31, 2012 was identified among eligible adults. Patients were required to have continuous medical and pharmacy benefits for 6 months pre- and 12 months post-index. Discrete VOC claims identified within a 3-day gap were combined as a single VOC episode. Annual all-cause …

Three Essays On Health Economics And Policy Evaluation, Shishir Shakya

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation consists of three essays on the U.S. Health care policy. Each paragraph below refers to the three abstracts for the three chapters in this dissertation, respectively. I provide quantitative evidence on how much Prescription Drug Monitoring Programs (PDMPs) affects the retail opioid prescribing behaviors. Using the American Community Survey (ACS), I retrieve county-level high dimensional panel data set from 2010 to 2017. I employ three separate identification strategies: difference-in-difference, double selection post-LASSO, and spatial difference-in-difference. I compare how the retail opioid prescribing behaviors of counties, that are mandatory for prescribers to check the PDMP before prescribing controlled substances …

Medicaid Coverage Across The Income Distribution Under The Affordable Care Act, Charles J. Courtemanche, James Marton, Aaron Yelowitz

Institute for the Study of Free Enterprise Working Papers

This chapter examines trends in Medicaid enrollment across the income distribution after the ACA’s Medicaid expansion.Using data from the American Community Survey between 2012and 2017, we compare Medicaid coverage over time in 9 states that expanded Medicaid in 2014 with no previous expansion for able-bodied, working-age adults with 12 states that had not expanded Medicaid by 2019 and also had no previous expansion for such adults. A difference-in-differences model is used to formalize this comparison. Similar to many previous studies, we find that Medicaid coverage increased dramatically for income-eligible adults under 138% of the federal poverty level (FPL). In addition, …

The Effects Of The Affordable Care Act Medicaid Expansion On Breast And Cervical Cancer Screening Rates On Low-Income Childless Women, Michelle Raissa Kobou Wafo

Economics

In 2010, the Obama administration passed the Patient Protection and Affordable Care Act (ACA) commonly known as Obamacare. However, it is in 2014 that several key parts of the ACA went into effect. Among those key parts is the Medicaid expansion program. States that chose to adopt the policy, expanded Medicaid access to everyone under 138 percent of the federal poverty line. This extension had the largest impact on childless adults who previously were not covered by the program. Moreover, ACA made it mandatory for all health plans (private and public) to include the ten essential health benefits in their …

Does Medicaid Increase Emergency Room Use: Evidence From Oregon Health Program?, Md Fourkan

Electronic Theses and Dissertations

This thesis paper strives to identify the relationship between Medicaid expansion and Emergency Department use. I use a Monte Carlo simulation for demonstrating the endogeneity problem and a copula model using the Oregon Health Program (OHP) data to show the previous literature has exaggerated the causal relation between Medicaid expansion and Emergency Department use. This paper can be divided into two parts. First, it tries to focus on the under-identification of multiple endogenous variables problem in typical econometrics papers, where researchers correct for a single endogenous variable but intentionally or unintentionally ignore the endogeneity of one or more other independent …

Effects Of The Affordable Care Act On Health Behaviors After Three Years, Charles J. Courtemanche, James Marton, Benjamin Ukert, Aaron Yelowitz, Daniela Zapata

Institute for the Study of Free Enterprise Working Papers

This paper examines the impacts of the Affordable Care Act (ACA) – which substantially increased insurance coverage through regulations, mandates, subsidies, and Medicaid expansions – on behaviors related to future health risks after three years. Using data from the Behavioral Risk Factor Surveillance System and an identification strategy that leverages variation in pre-ACA uninsured rates and state Medicaid expansion decisions, we show that the ACA increased preventive care utilization along several dimensions, but also increased risky drinking. These results are driven by the private portions of the law, as opposed to the Medicaid expansion. We also conduct subsample analyses by …

The Effect Of Expansions In Medicaid Eligibility On Hospital Financial Performance: Evidence From Medicare Cost Reports, Kevin Wu

Theses and Dissertations

Expansions in Medicaid eligibility and effects on profitability for different hospitals are examined using data from Medicare Cost Reports and difference-in-differences analysis. Critical access and disproportionate share hospitals are associated with the largest profitability gains from these expansions. Results imply that vulnerable hospitals are affected most by changes to Medicaid.

Essays On The Role Of Government Regulation And Policy In Health Care Markets, Grayson L. Forlines

Theses and Dissertations--Economics

Understanding how health care markets function is important not only because competition has a direct influence on the price and utilization of health care services, but also because the proper functioning, or lack thereof, of health care markets has a very real impact on patients who depend on health care markets and providers for their personal well-being. In this dissertation, I examine the role of government policies and regulation in health care markets, with a focus on the response of health care providers. In Chapter 1, I analyze the impact of Medicare payment rules on hospital ownership of physician practices. …

Early Effects Of The Affordable Care Act On Health Care Access, Risky Health Behaviors, And Self-Assessed Health, Charles J. Courtemanche, James Marton, Benjamin Ukert, Aaron Yelowitz, Daniela Zapata

Institute for the Study of Free Enterprise Working Papers

The goal of the Affordable Care Act (ACA) was to achieve nearly universal health insurance coverage through a combination of mandates, subsidies, marketplaces, and Medicaid expansions, most of which took effect in 2014. We use data from the Behavioral Risk Factor Surveillance System to examine the impacts of the ACA on health care access, risky health behaviors, and self-assessed health after two years. We estimate difference-in-difference-in-differences models that exploit variation in treatment intensity from state participation in the Medicaid expansion and pre-ACA uninsured rates. Results suggest that the ACA led to sizeable improvements in access to health care in both …

Pregnancy Medicaid Expansions And Fertility: Differentiating Between The Intensive And Extensive Margins, Lincoln H. Groves, Sarah Hamersma, Leonard M. Lopoo

Center for Policy Research

The theoretical and empirical links between public health insurance access and fertility in the United States remain unclear. Utilizing a demographic cell-based estimation approach with panel data (1987-1997), we revisit the large-scale Medicaid expansions to pregnant women during the 1980s to estimate the heterogeneous impacts of public health insurance access on childbirth. While the decision to become a parent (i.e., the extensive margin) appears to be unaffected by increased access to Medicaid, we find that increased access to public health insurance positively influenced the number of high parity births (i.e., the intensive margin) for select groups of women. In particular, …

Medicaid Managed Care And The Health Care Utilization Of Foster Children, Makayla Palmer, James Marton, Aaron Yelowitz, Jeffery Talbert

Molasky Family Department of Economics and Real Estate Faculty Research

A recent trend in state Medicaid programs is the transition of vulnerable populations into Medicaid managed care (MMC) who were initially carved out of such coverage, such as foster children or those with disabilities. The purpose of this article is to evaluate the impact of the transition of foster children from fee-for-service Medicaid coverage to MMC coverage on outpatient health care utilization. There is very little empirical evidence on the impact of managed care on the health care utilization of foster children because of the recent timing of these transitions as well as challenges associated with finding data sets large …

How Did The Aca Affect Health Insurance Coverage In Kentucky?, Aaron Yelowitz

Institute for the Study of Free Enterprise Working Papers

The major components of the Affordable Care Act (ACA) were implemented in 2014, including the rollout of the Health Insurance Marketplace, Medicaid expansions, and the individual mandate. Kentucky stands out as one of the few southern states to expand Medicaid, and earlier work has demonstrated that Kentucky experienced some of the largest gains in health insurance coverage. The goal of the current study is to further explore the sources that individuals used to gain coverage in Kentucky using a large, publicly available dataset, the American Community Survey (ACS). Several findings emerge. First, overall health insurance coverage increased by 5.7 percentage …

Eligibility Recertification And Dynamic Opt-In Incentives In Income-Tested Social Programs: Evidence From Medicaid/Chip, Zhuan Pei

Upjohn Institute Working Papers

Conventional labor supply studies assume constant eligibility monitoring of income-tested program participants, but this is not true for most programs. For example, states can allow children to enroll in Medicaid/CHIP for 12 months regardless of family income changes. A long recertification period reduces monitoring costs but is predicted to induce program participation by temporary income adjustments. However, I find little evidence of strategic behavior from the 2001 and 2004 Survey of Income and Program Participation. Given the lack of dynamic responses, I propose a framework to compute the optimal recertification period and find 12 months to be its lower bound.

Medicaid Crowd-Out Of Other Public Health Spending: Modeling Economic & Health Effects, Glen P. Mays

Health Management and Policy Presentations

MOTIVATION: Thirty states are expanding Medicaid eligibility under the Affordable Care Act (ACA) as of 2015, and while federal funds cover most costs for newly eligible recipients, states must share the additional costs of covering previously-eligible state residents who enroll in Medicaid. States, together with their local government counterparts, also provide the vast majority (87%) of public sector funds for public health programs designed to promote health and prevent disease and injury on a population-wide basis. Fiscal constraints and generous federal matching funds create strong budgetary incentives for states to channel their health-related spending to Medicaid rather than to other …

Medicaid And The Labor Supply Of Single Mothers: Implications For Health Care Reform, Vincent Pohl

Upjohn Institute Working Papers

The Patient Protection and Affordable Care Act expands Medicaid and introduces health insurance subsidies, thereby changing work incentives for single mothers. To undertake an ex ante policy evaluation of the employment effects of the PPACA, I structurally estimate a model of labor supply and health insurance choice exploiting existing variation in Medicaid policies. Simulations show that single mothers increase their labor supply at the extensive and the intensive margin by six and five percent, respectively. The PPACA leads to crowding-out of employer-sponsored health insurance of about 40 percent and increases single mothers' welfare by about $190 per month.

The Dynamics Of Medicaid & Public Health Spending: Implications For Aca Implementation, Glen P. Mays

Health Management and Policy Presentations

We estimate the dynamics and interactions of governmental spending on Medicaid and other public health services in all 50 states over a 15 year period. Using a quasi-experimental design with instrumental variables estimation, we find evidence that increased Medicaid spending leads to reduced governmental spending on other public health services, consistent with a crowd-out effect. Over 10 years, such crowd-out has the potential to diminish the health status improvements generated through health insurance coverage expansions.

Medicaid Expansions & Public Health Spending: Cross-Subsidies, Complementarities, And Crowd-Out, Glen P. Mays

Health Management and Policy Presentations

In this paper we estimate the causal impact of state Medicaid enrollment expansions and expenditures on state and local resources allocated to other public health programs and services. Using a quasi-experimental design with instrumental variables estimation, we find evidence that increased Medicaid spending leads to reduced governmental spending on other public health services, consistent with a crowd-out effect. Over 10 years, such crowd-out has the potential to diminish the health status improvements generated through health insurance coverage expansions.

Does Medicaid Crowd Out Other Public Health Spending? Projecting Aca’S Health & Economic Effects, Glen P. Mays

Health Management and Policy Presentations

Research Objective: Twenty-six states are expanding Medicaid eligibility under the Affordable Care Act (ACA) in 2014, and while federal funds cover most costs for newly eligible recipients, states must share the additional costs of covering previously-eligible state residents who newly enroll in Medicaid in response to ACA’s expanded outreach and enrollment incentives. States, together with their local government counterparts, also provide the vast majority (87%) of public sector funds for public health programs designed to promote health and prevent disease and injury on a population-wide basis. Fiscal constraints and generous federal matching funds create strong budgetary incentives for states to …

The Effect Of Public Insurance Coverage For Childless Adults On Labor Supply, Laura Dague, Thomas C. Deleire, Lindsey Leininger

Upjohn Institute Working Papers

This study provides plausibly causal estimates of the effect of public insurance coverage on the employment of nonelderly, nondisabled adults without dependent children (“childless adults”). We use regression discontinuity and propensity score matching difference-in-differences methods to take advantage of the sudden imposition of an enrollment cap, comparing the labor supply of enrollees to eligible applicants on a waitlist. We find that enrollment into public insurance leads to sizable and statistically meaningful reductions in employment up to at least nine quarters later, with an estimated size of 2–10 percentage points, depending on the model used.

A Profile Of Kentucky Medicaid Mental Health Diagnoses, 2000‐2010, Michael T. Childress

CBER Research Report

Good policy is dependent upon good data. This is especially true in health policy. Here we provide data on the number of Kentucky Medicaid beneficiaries who have received a mental or behavioral health diagnosis from 2000 to 2010. A Profile of Kentucky Medicaid Mental Health Diagnoses, 2000‐2010 provides information on the total number of individuals who have been diagnosed with a mental health disorder as well as a year‐by‐year count of the 15 broad categories used to classify these diagnoses. Presented for children (age 18 and younger) and adults (19 and older), these data are organized at the state, regional, …

Kentucky Medicaid Pharmaceutical Utilization Guide, 2000‐2010, Michael T. Childress

CBER Research Report

From the preface:

Understanding Medicaid pharmaceutical utilization in Kentucky is important: over $6.6 billion was expended in the state from 2000 to 2010 on outpatient medication; it has the potential to fundamentally transform the health and well‐being individuals, and by extension wider communities; and there is a continuing trend in the nonmedical use (and abuse) of prescription drugs, exacting a heavy toll on individuals, their families, and the wider community. The Kentucky Medicaid Pharmaceutical Utilization Guide, 2000‐2010 provides information on the 50 most utilized pharmaceuticals in Kentucky with respect to prescriptions, costs, and total grams—and presents this information for children …
