Essays On Market Inefficiencies Arising From Information Asymmetry And Market Power, Ming Ge Nov 2023

Essays On Market Inefficiencies Arising From Information Asymmetry And Market Power, Ming Ge

Doctoral Dissertations

This dissertation comprises three chapters that empirically investigate various kinds of market inefficiencies arising from seller misbehaviors. The first two chapters focus on physicians' overtreatment in healthcare markets. A standard reputation system falls short of effectively curbing overtreatment due to the credence-good nature of such a market: patients cannot tell whether a high-cost treatment recommendation (versus a less costly and complex treatment) is necessary even after the service is completed. In the first chapter, I propose a novel solution to reinstate the function of reputation by combining a reputation mechanism with patient search for second opinions. I conduct a laboratory …


Three Essays On Health, Risk And Behavior, Irene Mussio Nov 2018

Three Essays On Health, Risk And Behavior, Irene Mussio

Doctoral Dissertations

Health-related decisions could be explained by a variety of factors, ranging from the perception of the risk the activity involves to the knowledge of the long-term effects of the decision. An individual deciding to eat unhealthy or not to exercise could face health problems in the long-run. Individuals with health issues have been found to be more risk averse when it comes to financial decisions, such as portfolio allocation. Financial incentives to engage in healthier behaviors have been successful but short-lived. Prior research leaves many questions such as: What are the factors that explain why an individual decides to engage …


Three Essays On Child Welfare In Côte D’Ivoire, Didier Wayoro Oct 2018

Three Essays On Child Welfare In Côte D’Ivoire, Didier Wayoro

Doctoral Dissertations

The objective of this dissertation is to examine the impact of early life events such as civil conflicts and rainfall variability on child welfare in Côte d’Ivoire and investigate possible mitigating factors. It consists of three essays. Focusing on the 2010-2011 post-electoral violence, the empirical results from the first essay show that armed conflicts reduce the birth weight of newborn children who were in-utero during the conflict and increase the probability among exposed pregnant women of having an underweight child at birth. In addition, the study suggests that the impact of conflict on birth weight and low birth weight (less …


Labor Force Participation, Disability, And Implications For Healthcare Utilization And Employment, Lawrence C. Pellegrini Mar 2017

Labor Force Participation, Disability, And Implications For Healthcare Utilization And Employment, Lawrence C. Pellegrini

Doctoral Dissertations

The study period (i.e., 1999-2014) is characterized by declining labor force participation rates, rising disability enrollment, varying healthcare utilization, and increasing and changing composition of healthcare provider employment. However, little is known about the effect labor force participation and disability enrollment both have on the US healthcare system (i.e., healthcare utilization and employment). This dissertation is comprised of three manuscripts answering questions related to these relationships. Results show that labor force participation is a more robust indicator than the unemployment rate for exploring the effect of the labor market on healthcare spending and health outcomes, with healthcare spending itself exhibiting …


Three Essays On The Social Determinants Of Early Childhood Health And Development, Andrew Barenberg Nov 2016

Three Essays On The Social Determinants Of Early Childhood Health And Development, Andrew Barenberg

Doctoral Dissertations

This three-paper dissertation examines the social determinants of early childhood and in-utero health. The first chapter examines the impact of early childhood stunting on educational outcome in Tanzania. Using the extent of third-trimester overlap with the Tanzania hunger season to create an exogenous variation in stunting, I find that a one standard deviation stunting decreases educational achievement by .88 school years compared to a child's siblings. A placebo group not affected by the hunger season is used to confirm that in-utero nutrition deprivation is the cause of the education differences. The second paper utilizes the food price shocks and price …


Essays On Household Health Expenditures, National Health Insurance And Universal Access To Health Care In Ghana, Evelyn Kwakye Mar 2016

Essays On Household Health Expenditures, National Health Insurance And Universal Access To Health Care In Ghana, Evelyn Kwakye

Doctoral Dissertations

Access to quality health services is essential for maintaining a healthy population and economic development hence the growing global consensus that universal health coverage is necessary. Ghana attempts to expand access by making basic health services free at the point of delivery through its National Health Insurance Scheme (NHIS). Prior studies indicate NHIS increases demand for health services, but questions remain about its impact on out of pocket payments, quality of services, and the financial viability of the program. Hence, this dissertation analyzes the financial risk in health care seeking, the effect of NHIS on out of pocket payments and …


Economics Of Fixed-Dose Combination Drugs Approved In The United States, Jing Hao Nov 2015

Economics Of Fixed-Dose Combination Drugs Approved In The United States, Jing Hao

Doctoral Dissertations

Patent is the most important form of intellectual property protection for new drugs. Patent extension and market exclusivity currently serve as major regulatory incentives to promote new drugs. Combination drug, or fixed-dose combination (FDC) are formulations that contain two or more active ingredients in a single pill. FDCs, especially combinations of singe drugs that are already in the market, are common strategy for brand-name drug companies to extent the patent and exclusivity life. The substitution of single drug products that soon have generic alternatives with newer, brand-name combinations lead to potential increases in pharmaceutical expenditures and raises concerns on economic …


Determinants Of Health Care Use Among Rural, Low-Income Mothers And Children: A Simultaneous Systems Approach To Negative Binomial Regression Modeling, Swetha Valluri Jan 2011

Determinants Of Health Care Use Among Rural, Low-Income Mothers And Children: A Simultaneous Systems Approach To Negative Binomial Regression Modeling, Swetha Valluri

Masters Theses 1911 - February 2014

The determinants of health care use among rural, low-income mothers and their children were assessed using a multi-state, longitudinal data set, Rural Families Speak. The results indicate that rural mothers’ decisions regarding health care utilization for themselves and for their child can be best modeled using a simultaneous systems approach to negative binomial regression. Mothers’ visits to a health care provider increased with higher self-assessed depression scores, increased number of child’s doctor visits, greater numbers of total children in the household, greater numbers of chronic conditions, need for prenatal or post-partum care, development of a new medical condition, and …
