Equitable Taxation and the Provision of Health Insurance Subsidies

Current U.S. income tax laws allow many taxpayers to exclude from taxable income part or all of the cost of acquiring health insurance through an employer‐sponsored benefit plan. This favorable tax treatment generally applies regardless of whether the employer or employee actually pays the health insurance premiums. We describe the effects of this tax policy on the U.S. tax system's horizontal and vertical equity. We also explain how taxpayers covered by employer‐sponsored plans are significantly subsidized by the government in acquiring health insurance, whereas taxpayers who acquire health insurance by other means or who are not covered by health insurance at all receive no such government assistance. We conclude that any prospective health‐care policy initiatives, including modifications to the 2010 health‐care reforms, should contemplate both the horizontal and vertical equity of the tax treatment of health insurance premiums.     

Worker Turnover,Capital Dispersion,and Matching

Abstract. A model acknowledging technology and wage dispersion, search frictions, and costly worker turnover is used for testing the notion of random matching. Using a linked employer–employee data set on roughly 9,000 Norwegian establishments and 200,000 jobs during the period 1989–95, I show that establishments investing more in capital, pay more, and experience lower worker turnover rate. Strictly convex turnover costs are identified. High‐wage establishments post on average less intensively than low‐wage establishments. Positive relationships between wages and posting are observed for high‐tech industries and in the capital and surroundings. Thus, the notion of random matching is generally rejected.     

An Equilibrium Model of Health Insurance Provision and Wage Determination

We investigate the effect of employer‐provided health insurance on job mobility rates and economic welfare using a search, matching, and bargaining framework. In our model, health insurance coverage decisions are made in a cooperative manner that recognizes the productivity effects of health insurance as well as its nonpecuniary value to the employee. The resulting equilibrium is one in which not all employment matches are covered by health insurance, wages at jobs providing health insurance are larger (in a stochastic sense) than those at jobs without health insurance, and workers at jobs with health insurance are less likely to leave those jobs, even after conditioning on the wage rate. We estimate the model using the 1996 panel of the Survey of Income and Program Participation, and find that the employer‐provided health insurance system does not lead to any serious inefficiencies in mobility decisions.     

Identifying Equilibrium Models of Labor Market Sorting

We assess the empirical content of equilibrium models of labor market sorting based on unobserved (to economists) characteristics. In particular, we show theoretically that all parameters of the classic model of sorting based on absolute advantage in Becker, 1973 with search frictions can be nonparametrically identified using only matched employer–employee data on wages and labor market transitions. In particular, these data are sufficient to nonparametrically estimate the output of any individual worker with any given firm. Our identification proof is constructive and we provide computational algorithms that implement our identification strategy given the limitations of the available data sets. Finally, we add on‐the‐job search to the model, extend the identification strategy, and apply it to a large German matched employer–employee data set to describe detailed patterns of sorting and properties of the production function.     

Health care economics is changing--the law is sure to follow

Law is intimately related to economics. As the economic relationships in a market change, the legal landscape evolves accordingly. Even if no health care reform is enacted at the federal level, ever-increasing portions of today's managed indemnity sector will convert to plans constraining enrollee choice and seeking to deliver cost-effective care through risk-sharing relationships (both corporate and contractual) with providers. This is inevitable, given employer and federal government pricing demands, and it is changing the face of health care law. If federal reform is enacted and/or the systems adopted in Minnesota, Maryland, Washington, and Florida (to name a few) are replicated elsewhere, the legal concerns of physicians and other providers will shift even more dramatically. In this article, some of the legal fall-out from these economic developments is discussed.     

COMPETITION AND GENDER PREJUDICE: ARE DISCRIMINATORY EMPLOYERS DOOMED TO FAIL?

According to Becker's famous theory on discrimination (Gary Becker, 1957 , The Economics of Discrimination, University of Chicago Press), entrepreneurs with a strong prejudice against female workers forgo profits by submitting to their tastes. In a competitive market their firms lack efficiency and are therefore forced to leave. We present new empirical evidence for this prediction by studying the survival of start‐up firms in longitudinal matched employer–employee data. We find that firms with strong preferences for discrimination approximated by a low share of female employees relative to the industry average have significantly shorter survival rates. This is especially relevant for firms starting out with female shares in the lower tail of the distribution. Competition at the industry level additionally reduces firm survival and accelerates the rate at which prejudiced firms are weeded out. We also find evidence for employer learning as highly discriminatory start‐up firms that manage to survive submit to market powers and increase their female workforce over time.     

Flexible Work Arrangements and Intentions of Unemployed Women in Cyprus: A Planned Behaviour Model

Drawing from the theory of planned behaviour, we use 18 focus groups with 113 unemployed women and 150 mail questionnaires to explore whether and how unemployed Cypriot women's subjective norms, attitudes, perceived behavioural control and job versus career aspirations influence their intentions to adopt employee‐ and employer‐driven flexible work arrangements. To analyse the information gathered, we used a combination of content analysis, an external panel of practitioners and academics, principal components analysis, and regressions. Results show that women's positive attitudes towards child‐caring and self‐enhancement and their subjective norms of organizational inflexibility were positively related mainly with intentions to adopt employee‐driven flexible work arrangements. Further, women who found childcare support and employer requirements limiting were more interested in telework; the latter were also more interested in temporary work. Finally, women's career aspirations were related with weekend work and telework, whilst their job aspirations were associated with temporary work. Results raise issues for employers and policy‐makers in Cyprus, and possibly other southern European countries facing similar challenges, in supporting women to become fully integrated in the labour market.     

Firm‐level Evidence on Gender Wage Discrimination in the Belgian Private Economy

In this paper we explore a matched employer–employee data set to investigate the presence of gender wage discrimination in the Belgian private economy labour market. Contrary to many existing papers, we analyse gender wage discrimination using an independent productivity measure. Using firm‐level data, we are able to compare direct estimates of a gender productivity differential with those of a gender wage differential. We take advantage of the panel structure to identify gender‐related differences from within‐firm variation. Moreover, inspired by recent developments in the production function estimation literature, we address the problem of endogeneity of the gender mix using a structural production function estimator alongside instrumental variable‐general method of moments (IV‐GMM) methods where lagged value of labour inputs are used as instruments. Our results suggest that there is no gender wage discrimination inside private firms located in Belgium, on the contrary.     

Sources of Job and Worker Flows: Evidence from a Panel of Regions

Abstract. This study explores the structure and the dynamics of regional job and worker flows. The measures of job and worker flows are related to economic fluctuations, demographic factors and industry structure by employing the data of 85 Finnish regions over the period 1988–97. It is shown that labour market dynamics differ markedly between regions. As in previous analyses of linked employer–employee data, job and worker flows are shown to behave cyclically. In addition, the results indicate that observable differences in regional productivity, in‐migration, demographics and industry structure help to explain the prevailing disparities in regional labour markets.     

Workplace Job Satisfaction in Britain: Evidence from Linked Employer–Employee Data

The paper examines the nature of workplace job satisfaction in Britain using an ‘overall’ and domain‐specific job satisfaction outcomes from linked employer–employee data. A measure of aggregate job satisfaction alone might mask domain‐specific differences in satisfaction, something the combined approach in this paper addresses. As well as controlling for a rich set of correlates on employees and their workplaces, the paper deploys alternative empirical models that account for employee‐ and workplace‐level unobserved heterogeneity. The paper reports interesting results on the link between job satisfaction and observed as well as unobserved characteristics of employees and their workplaces.     

Firm‐level Consequences of Large Minimum‐wage Increases in the Czech and Slovak Republics

Abstract. After an initial decline in the level of real minimum‐wage rates, there were series of unusually large increases in their levels — 70 and 50 per cent — during the years 1999–2002 in the Czech and Slovak Republics, respectively. Using information from matched employee–employer data sets, we look at the impact of minimum‐wage hikes on both wages and employment. Our results suggest that there are some, but not substantial, job losses in reaction to minimum‐wage hikes and that the impact on firm wages is rather large, implying that further increases of similar magnitude might very well have negative consequences for employment.     

Do Human Resource Practices Enhance Organizational Commitment in SMEs with Low Employee Satisfaction?

This paper considers a large matched employee–employer data set to estimate a model of organizational commitment. In particular, it focuses on the role of firm size and management formality to explain organizational commitment in British small and medium‐sized enterprises (SMEs) with high and low levels of employee satisfaction. It is shown that size ‘in itself’ can explain differences in organizational commitment, and that organizational commitment tends to be higher in organizations with high employee satisfaction compared with organizations of similar size with low employee satisfaction. Crucially, the results suggest that formal human resource (HR) practices can be used as important tools to increase commitment and thus, potentially, effort and performance within underperforming SMEs with low employee satisfaction. However, formal HR practices commonly used by large firms may be unnecessary in SMEs which benefit from high employee satisfaction and positive employment relations within a context of informality.     

Purchasers and the impact of managed care on physicians

In much the same way that demands by managed care organizations are shaping the way physicians practice, health care purchasers impact how managed care organizations operate. Corporations purchase managed health care through their employee benefits programs, and understanding the language, objectives, and limitations of these purchasers is essential to grasping the forces influencing managed care organizations and the modern practice of medicine. The emergence of value-based purchasing as a strategic corporate approach to health benefits programs will dictate the forces on physicians, hospitals, and managed care organizations for years to come. These forces have already led to price reductions, health plan accreditation, employee-directed report cards, outcomes management, and organized systems of care, and they will determine the broad outlines of the emerging U.S. health care system.     

Exploring Job Satisfaction in Private and Public Employment: Empirical Evidence from Greece

Abstract. This paper analyses subjective job satisfaction (JS) responses by employees in the public and private sectors of the Greek labour market. Panel data covering the period 1995–2001 and a random effects ordered probit model are used for estimation purposes. The results of the econometric estimation show that a substantial JS differential exists between the two sectors, in every JS domain and always in favour of public employment. A typical ordered decomposition analysis indicates that about one‐third of the difference in expected JS can be explained by differences in employee characteristics and two‐thirds by unobserved sector‐specific inbuilt features. The comparison of wage reductions, which a representative employee will be prepared to endure in order to avoid employment in the private sector, reveals that the regularity of working schedules is appreciated more than any other facet of JS. The obtained results enhance the existing apparatus for evaluating government policies in the labour market.     

Employee Well‐being and the HRM–Organizational Performance Relationship: A Review of Quantitative Studies

There is a lack of consensus on the role of employee well‐being in the human resource management–organizational performance relationship. This review examines which of the competing perspectives –‘mutual gains’ or ‘conflicting outcomes’– is more appropriate for describing this role of employee well‐being. In addition, this review examines whether study attributes such as the measurement of key variables, the level of analysis and the study design affect a study's outcomes. The review covers 36 quantitative studies published from 1995 to May 2010. Employee well‐being is described here using three dimensions: happiness, health and relationship. The main findings are that employee well‐being in terms of happiness and relationship is congruent with organizational performance (mutual gains perspective), but that health‐related well‐being appears to function as a conflicting outcome. Directions for future research and theoretical development are suggested.     

The Impact of Worker and Establishment‐level Characteristics on Male–Female Wage Differentials: Evidence from Danish Matched Employee–Employer Data

Abstract. This paper uses matched employer–employee data from Denmark to examine how gender segregation at the level of occupation, industry, establishment, and job‐cell impacts the gender wage differential of full‐time, private‐sector salaried and manual workers. Wage effects of gender segregation at the above four levels are estimated through fixed effects or through controls for the proportion females within these structures. We find that occupation has a much larger role than industry or establishment in accounting for the gender gap for salaried but not manual workers, and that for both groups there is a significant within‐job‐cell gender wage differential.     

The Effects of Health Insurance and Self‐Insurance on Retirement Behavior

This paper provides an empirical analysis of the effects of employer‐provided health insurance, Medicare, and Social Security on retirement behavior. Using data from the Health and Retirement Study, we estimate a dynamic programming model of retirement that accounts for both saving and uncertain medical expenses. Our results suggest that Medicare is important for understanding retirement behavior, and that uncertainty and saving are both important for understanding the labor supply responses to Medicare. Half the value placed by a typical worker on his employer‐provided health insurance is the value of reduced medical expense risk. Raising the Medicare eligibility age from 65 to 67 leads individuals to work an additional 0.074 years over ages 60–69. In comparison, eliminating 2 years worth of Social Security benefits increases years of work by 0.076 years.     

Workplace Change and Employee Mental Health: Results from a Longitudinal Study

This study is intended to improve understanding of the impact of workplace change on employee mental health and well‐being. We construct and test a comprehensive measure of organizational change, which is then applied in a prospective longitudinal study of nearly 5400 employees in six UK National Health Service Trusts. Self‐rated mental health was assessed using the 12‐item version of the General Health Questionnaire (GHQ). Just under a quarter of the sample were at increased risk of psychiatric morbidity (‘cases’). After controlling for a wide range of personal characteristics and work variables, it was found that respondents who reported an increase in the amount of work over the previous year were more likely to be classed as GHQ cases, whereas increased training and promotion and improved job security had a beneficial effect on employee mental health (less likelihood of being GHQ cases). Quantity or degree of change showed a somewhat ambiguous relationship with GHQ status. Our findings challenge the assumption that change will necessarily have an adverse effect on health, indicating areas, such as promotion and development, where a positive impact might be anticipated.     

Insurer Competition in Health Care Markets

The impact of insurer competition on welfare, negotiated provider prices, and premiums in the U.S. private health care industry is theoretically ambiguous. Reduced competition may increase the premiums charged by insurers and their payments made to hospitals. However, it may also strengthen insurers' bargaining leverage when negotiating with hospitals, thereby generating offsetting cost decreases. To understand and measure this trade‐off, we estimate a model of employer‐insurer and hospital‐insurer bargaining over premiums and reimbursements, household demand for insurance, and individual demand for hospitals using detailed California admissions, claims, and enrollment data. We simulate the removal of both large and small insurers from consumers' choice sets. Although consumer welfare decreases and premiums typically increase, we find that premiums can fall upon the removal of a small insurer if an employer imposes effective premium constraints through negotiations with the remaining insurers. We also document substantial heterogeneity in hospital price adjustments upon the removal of an insurer, with renegotiated price increases and decreases of as much as 10% across markets.
