The Relationship Between Conflict And Longevity: A Panel Data Analysis, Felicitas Adu-Acheampong

Wayne State University Dissertations

With a series of multivariate regression models this study investigates the association of conflict, health and non-health inputs with different facets of longevity in OECD, emerging and African countries. Using a country-level panel data set covering the period 1990 through 2014, five facets of longevity are examined: infant mortality, life expectancy for males at birth, life expectancy for females at birth, life expectancy for males at age 65, and life expectancy for females at age 65 among OECD and emerging countries. With country-level data spanning 1997 through 2016 from 50 African nations, production functions are also estimated for four distinct …

Statistical Analysis Of The Effect Of Work Conditions On Safety And Health In The U.S. Long-Haul Trucking Industry: Evidence From The Niosh Survey Data, Takahiko Kudo

Wayne State University Dissertations

Chapter 1 reviews the literature which analyzes the effect of compensation and work conditions on safety and health.

Chapter 2 analyzes how truck drivers’ compensation affects their safety performance, using moving violations as a proxy for safety. In addition to drivers’ pay per mile driven, we employ fringe benefits as independent variables. The result suggests that the rate of pay per mile driven, and employment-based health insurance, significantly decrease the probability of moving violations. The result provides support for the hypothesis that high compensation for drivers improve drivers’ safety performance, though other forms of compensation are not significantly related to …

The Demand And Supply Side Responses To Changes In Health Insurance Status, Naim Chy

Wayne State University Dissertations

We estimate the effects of having health insurance on the probability of facing trouble in accessing provider’s care and that of being refused as a new patient by the provider’s office in chapter 2 of this dissertation. The NHIS data for 2011-2015 are pooled. To fight the potential endogeneity problem arising from the selection bias associated with insurance status we use a 2SLS method with self-employment status of individual and family income as the instruments. The estimated results show that having health insurance reduces the probability of facing difficulty in getting provider’s appointment by 7.3 percentage points. On the other …

Medicaid Managed Care And Its Impact On Potentially Preventable Hospital Utilization (Inpatient And Emergency Room Visits), Mohammad Usama Toseef

Wayne State University Dissertations

Introduction: The objective of this study is to compare the performance of Medicaid health maintenance organizations (HMOs) and fee-for-service (FFS) Medicaid regarding the prevalence of potentially preventable hospitalizations and emergency room (ER) visits, a recognized measure of outpatient care quality.

Methods: Nationally representative data on non-institutionalized Medicaid recipients, ages 18-64, from the 2003-2012 Medical Expenditure Panel Survey. Separate analyses are conducted for recipients insured through both Medicaid and Medicare (“dual eligibles”) and recipients whose only health insurance is Medicaid (“non-duals”). In each group the occurrence of potentially preventable hospital use is measured, and then survey-weighted multivariable logistic regression models are …

Empirical Study Of Basic Violations, Pay Incentives, And Safety: Evidence From U.S. Intrastate Carriers, Shengyang Ju

Wayne State University Dissertations

Truck drivers are under financial pressure due to inadequacy in their compensation. Thus, they have strong incentives to work more legally or illegally in pursuing a higher income, which leads to fatigue and HOS violations and ultimately causes crashes. On the other hand, FMCSA oversees the motor carrier’s safety performance and tries to improve the current safety measurement since everyone pays a share of the economic costs due to the externality. This dissertation aims to explore the complex relationship between BASICs violations, pay incentives and crashes, to raise the importance of economic impact on carrier’s safety, and to test the …

Health And Natural Capital In An Augmented Solow Growth Model, Sa-Ad Iddrisu

Wayne State University Dissertations

This dissertation explains output growth in nations using two different forms of economic capital (health and natural capital) in separate models under paper 1 and 2. In paper 1, income per worker’s growth in the emerging market economies and developing economies is estimated using health capital. Previous studies done on health capital and output growth have mostly focused on Organization for Economic Co-operation and Development (OECD) and advanced economies, but I focused on emerging market economies and developing economies. I examined the association amongst health capital and economic growth in an augmented Solow Model, using total HEX per capita and …

Essays On Applications Of Spatial Econometric Models, Jihu Zhang

Wayne State University Dissertations

Since the infamous riot of 1967, high crime rates and negative media reports have labeled the city of Detroit as one of the most dangerous cities in the U.S. For a better understanding of crime situation in Detroit, we discuss the spatial interactions of crime rates among block groups as well as the impact of socioeconomic variables on crime by using spatial autoregressive models, crime data, and socioeconomic data. In particular, we introduced a geographical methodology: inverse distance weighting (IDW), which is mainly used to estimate distance based weighting from a scattered set of points. This paper is an essential …
