Doctor of Philosophy / Department of Economics / William F. Blankenau / This dissertation consists of three essays on how health and education affect the labor market outcomes of workers. Health and education issues have been key determinants of labor demand and supply. In light of increasing incidence of health problems and the rapid growth of post-baccalaureate certificates in the US, this dissertation seeks to answer questions about labor market outcomes of workers with poor health history and with post-baccalaureate certificates. The first essay which I co-authored with Dr. William Blankenau and Dr. Benjamin Schwab uses a résumé-based correspondence test to compare the employment consequences of an illness-related employment gap to those of an unexplained employment gap. The results of the experiment show that while the callback rate of applicants with an illness-related employment gap is lower than that of the newly unemployed, applicants with illness-related employment gaps are 2.3 percentage points more likely to receive a callback than identical applicants who provide no explanation for the gap. Our research provides evidence that employers use information on employment gaps as additional signals about workers' unobserved productivity. Co-authored with Dr. Amanda Gaulke and Dr. Hugh Cassidy, the second essay tests how employers perceive the value of post-baccalaureate certificates using the same methodology in the first essay. We randomly assign a post-baccalaureate certificate credential to fictitious résumés and apply to real vacancy postings for managerial, administrative and accounting assistant positions on a large online job board. We find that post-baccalaureate certificates are 2.4 percentage points less likely to receive a callback than those without this credential. However, this result is driven by San Francisco, and there is no effect in Los Angeles or New York. By occupation, we also find that there is only significant negative effect in administrative assistant jobs, and there is none in managerial or accounting assistant jobs. A typographical error made in the résumés of certificate holders regarding the expected year of completion of the certificate may also contribute to negative effects of a certificate. Using NLSY79 data, the third essay tests whether the source of health insurance creates incentives for newly-diagnosed workers to remain sufficiently employed to maintain access to health insurance coverage. I compare labor supply responses to new diagnoses of workers dependent on their own employment for health insurance with the responses of workers who are dependent on their spouse's employer for health insurance coverage. I find that workers who depend on their own job for health insurance are 1.5-5.5 percentage points more likely to remain employed and for those employed, are 1.3-5.4 percentage points less likely to reduce their labor hours and are 2.1-6.1 percentage points more likely to remain full-time workers.

As the literature on work–family conflict grows and absenteeism increasingly comes into the spotlight, one cannot help but ask the question: “What is an acceptable absenteeism rate and how can an organisation control and manage absenteeism?” With current absenteeism rates as high as 12% and with an estimated R12 million lost per annum because of absenteeism, the idea of an on-site employer-sponsored childcare facility seems viable. The purpose of this study is to examine the relationship between absenteeism and on-site employer- sponsored childcare. The following dimensions of absenteeism will be examined over a period of a year: absence frequency, absence intensity, attitudinal absence and medical absence. The results of two companies, one with a facility and one without, will then be compared in order to establish the relationship between absenteeism and an on-site facility. To date, evidence remains mixed and the ongoing challenge of establishing real return on equity remains a major barrier to the support of on-site employer-sponsored childcare. / Industrial & Organisational Psychology / M.

This dissertation examines heterogeneity in the value of a statistical life (henceforth VSL) stemming from employer-provided health insurance (henceforth EHI) and worker sorting. The dissertation consists of three essays. In the first essay (Chapter 2), I investigate the effect of health-driven productivity on the wage compensation for mortality risk, and how EHI influences VSL using the US labor market data. In this chapter I build a framework showing that the level of job risks influences the incentive of employers to provide EHI. The basic notion of the framework is that health insurance is an investment in health and health is a form of general human capital. Employers are willing to invest in employees' health and pay the associated costs as long as they can recoup the costs of health investment. Occupational hazards, however, are harmful to health; productivity gains from health tend to decline as risk increases, resulting in lower health investment made by employers. As a result, the workers in risky jobs have to contribute more to their health investment in the form of lower wages than do workers in safe jobs. This behavioral response pushes down the wage offer curve of the insured in high risk occupations. Consequently, workers with health insurance, on average, accept a lower risk premium, leading to a lower VSL. Empirical findings from this dissertation suggest evidence of heterogeneity in VSL due to health insurance status: the estimated VSL for workers with health insurance is lower than those without one. In the second essay (Chapter 3), I extend the framework of the second chapter into the United Kingdom (the UK) labor market. Different from the US, the UK has universal health care system in which all eligible individuals (almost all the UK citizens) are covered by publicly-provided health care. This chapter also provides evidence that private medical insurance in the universal health care system affects the risk premium. Despite the fact that the UK and the US have different institutional settings in health coverage, findings from the UK are, to some extent, qualitatively similar to the US. A major issue in estimates of VSL is that people are not randomly assigned to jobs. That is, heterogeneous people would sort into jobs based on their preferences on risk and safety-related skills. Thus, failure to account for heterogeneity in both risk preferences and safety-related skills will bias the estimated VSL. In the third essay (Chapter 4), I discuss worker sorting and how it may affect the mortality risk premium. In this chapter, I focus on the role of personality traits in safety-related skill and their influence on worker sorting based on job risk. I use Five-Factor Model of personality or also known as the ‘’Big Five” personality traits. The big 5 personality traits are extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. In my framework, these personality traits are inputs and the technology of skill formation transforms the traits into safety-related skill.
