Does health insurance reduce illness-related worker absenteeism?

The objective of this article is to examine whether having health insurance reduces illness-related absenteeism among older workers. A nationally representative sample of 1780 workers in the United States, aged 52–64, are drawn from the 2004–2006 Health and Retirement Study (HRS). Binary logistic regressions and censored Tobit models are estimated for workers’ likelihood of missing work days due to illness and the number of illness-related work days missed, respectively, while explicitly addressing the possibility of insurance-selection effects. The findings suggest that over a 12-month period, older workers without health insurance are as likely as insured workers to miss work days due to illness and there are no differences in the number of days missed between insured and uninsured workers. However, there is strong evidence that poor baseline health, onset of new diseases and longer hospitalization significantly increase an older worker's absenteeism at work. These results suggest that having health insurance does not affect illness-related absenteeism among older workers in the US. Future research examining other aspects of worker productivity, such as ‘presenteeism’, and the longer term effects of insurance on productivity can extend our understanding of the role of health insurance in the workplace.     

Political foundations of the resource curse

In this paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse. We show: (1) politicians tend to over-extract natural resources relative to the efficient extraction path because they discount the future too much, and (2) resource booms improve the efficiency of the extraction path. However, (3) resource booms, by raising the value of being in power and by providing politicians with more resources which they can use to influence the outcome of elections, increase resource misallocation in the rest of the economy. (4) The overall impact of resource booms on the economy depends critically on institutions since these determine the extent to which political incentives map into policy outcomes. Countries with institutions that promote accountability and state competence will tend to benefit from resource booms since these institutions ameliorate the perverse political incentives that such booms create. Countries without such institutions however may suffer from a resource curse.     

Examining the association of smoking with work productivity and associated costs in Japan

Aims: Smoking is associated with significant health and economic burden globally, including an increased risk of many leading causes of mortality and significant impairments in work productivity. This burden is attenuated by successful tobacco cessation, including reduced risk of disease and improved productivity. The current study aimed to show the benefits of smoking cessation for workplace productivity and decreased costs associated with loss of work impairment.

Materials and methods: The data source was the 2011 Japan National Health and Wellness Survey (n?=?30,000). Respondents aged 20–64 were used in the analyses (n?=?23,738) and were categorized into: current smokers, former smokers, and never smokers. Generalized linear models controlling for demographics and health characteristics examined the relationship of smoking status with the Work Productivity and Activity Impairment questionnaire (WPAI-GH) endpoints, as well as estimated indirect costs.

Results: Current smokers reported the greatest overall work impairment, including absenteeism (i.e. work time missed) and presenteeism (i.e. impairment while at work); however, after controlling for covariates, there were no significant differences between former smokers and never smokers on overall work impairment. Current smokers and former smokers had greater activity impairment (i.e. impairment in daily activities) than never smokers. Current smokers reported the highest indirect costs (i.e. costs associated with work impairment); however, after controlling for covariates, there were no significant differences between former smokers and never smokers on indirect costs.

Limitations and conclusions: Smoking exerts a large health and economic burden; however, smoking cessation attenuates this burden. The current study provides important further evidence of this association, with former smokers appearing statistically indistinguishable from never smokers in terms of work productivity loss and associated indirect costs among a large representative sample of Japanese workers. This report highlights the workplace benefits of smoking cessation across productivity markers and cost-savings.     

Shift work in nursing: is it really a risk factor for nurses' health and patients' safety?

There is evidence in the scientific literature of the adverse physiological and psychological effects of shift work, including disruption to biological rhythm, sleep disorders, health problems, diminished performance at work, job dissatisfaction, and social isolation. In this study, the results of health problems and sleep disorders between female and male nurses, between daytime and shift nurses, and between sleep-adjusted and non-sleep-adjusted shift nurses were compared. Also the relationship between adjustment to shift work and organizational outcomes (errors and incidents and absenteeism from work) was analyzed. Gender, age, and weight were more significant factors than shift work in determining the well-being of nurses. Shift work by itself was not found to be a risk factor for nurses' health and organizational outcomes in this study. Moreover, nurses who were identified as being "non-adaptive" to shift work were found to work as effectively and safely as their adaptive colleagues in terms of absenteeism from work and involvement in professional errors and accidents. This research adds two additional findings to the field of shift work studies. The first finding is that female shift workers complain significantly more about sleep disorders than male shift workers. Second, although high rates of nurses whose sleep was not adapted to shift work were found, this did not have a more adverse impact on their health, absenteeism rates, or performance (reported errors and incidents), compared to their "adaptive" and "daytime" colleagues.     

Take a risk: Preferring prevention over control of biological invaders

Scientists have argued that invasive species can be managed most cost effectively with greater investments in prevention. Further, under ideas like the precautionary principle it is reasonable to expect that a cautious manager would use more prevention relative to control because it keeps more invaders out. Yet, this is not typically done. In many cases, private and public resources are invested primarily to control existing invaders rather than to prevent new invasions. Managers frequently wait until after invaders have arrived and then scramble to limit the damages. We believe these paradoxical decisions can be understood by recognizing the link between typical human preferences for risk bearing and the technology of risk reduction. We demonstrate quantitatively how managers perceived to be cautious or averse to risk tend to shy away from prevention relative to control. This counterintuitive result arises because control is a safer choice than prevention because its productivity is relatively less risky: it works to remove existing invaders from the system. In contrast, the productivity of prevention is more uncertain because prevention only reduces the chance of invasion, it does not eliminate it, and invasion may not occur even in the absence of prevention. Managers' averse to risk will inherently avoid as much uncertainty as possible, whether the source of uncertainty regards ecological outcomes or economic productivity. Implications for environmental decision making are clear. In invasive species management, if managers act as though they are risk averse, their caution can backfire when it leads to more control rather than prevention. The social consequences of this choice are a greater probability of future invasions and lower social welfare. Our results suggest that social welfare is highest when managers were willing to “take a risk” with prevention.     

Why Would She? Polygyny and Women's Welfare in Ghana

This study examines whether polygynous marriages are beneficial to women in Ghana. While some scholars claim that women benefit from such marriages in terms of higher consumption or leisure time, others believe that such relationships can be oppressive for women, as compared to monogamous relationships. Using household data from the 2005/6 Ghanaian Living Standards Measurement Survey V and the 2008 Ghanaian Demographic Health Survey, this study finds little evidence to support the view that women experience economic benefits from these unions. Polygynous women in Ghana tend to be more accepting of and experience more domestic violence, and they have less decision-making power within the household than women in monogamous marriages. Thus, there seems to be more evidence to support the view of polygyny as an oppressive institution rather than the outcome of a woman's rational choice.     

The importance of employment status in determining exit rates from nursing

To mitigate nurse shortages, health care decision makers tend to employ retention strategies that assume nurses employed in full-time, part-time, or casual positions and working in different sectors have similar preferences for work. However, this assumption has not been validated in the literature. The relationship between a nurse's propensity to exit the nurse profession in Ontario and employment status was explored by building an extended Cox Proportional Hazards Regression Model using a counting process technique. The differential exit patterns between part-time and casual nurses suggest that the common practice of treating part-time and casual nurses as equivalent is misleading. Health care decision makers should consider nurse retention strategies specifically targeting casual nurses because this segment of the profession is at the greatest risk of leaving. Nurse executives and nurse managers should investigate the different work preferences of part-time and casual nurses to devise tailored rather than "one-size fits all" nurse retention strategies to retain casual nurses.     

Advances in supervision technology and economic welfare: a general equilibrium analysis

We analyze the impact of improvements in the technology by which employers monitor their workers. It is unclear a priori whether workers should benefit or not from such advances. On the one hand, they decrease the total costs of hiring workers and stimulate labor demand. On the other hand, as supervision becomes less costly employers tend to substitute monitoring for wages as a means of motivating workers. We show how the impact on firms and workers of such technological progress depends on the nature of the labor market equilibrium (i.e. whether there is full employment or not) and the cost (technology) of monitoring. A distinct possibility is that unemployed workers welcome the changes in supervision because they promote employment, while employed workers resist such changes and the more intensive supervision they encourage.     

任人唯亲还是任人唯贤*——来自北京市文化创业企业的证据

在中国传统文化和市场经济的双重环境下,企业在治理结构上是“任人唯亲”还是“任人唯贤”一直是一个存在争议的问题。从公司治理实践上看,两种治理模式各有优劣。那么,企业在什么情况下更可能“任人唯亲”呢？本文基于最优授权理论提出了一个理论框架,然后使用一个独特的创业企业调查数据,采取计量经济学方法进行了实证检验。本文的主要发现是：有创业经历的或文化水平低的企业主更愿意任用亲戚担任企业高管,而男性、有管理学背景或有银行贷款的企业主更不愿意任用亲戚担任企业高管。本文的研究结论对于当前“大众创业、万众创新”政策具有重要的理论意义。     

Using imported intermediate goods: Selection and technology effects

Producers that use imported intermediate goods tend to be much larger and more productive than others. Some of this is due to a selection effect: the most productive producers self‐select into importing because only they can overcome the fixed costs of developing trade relationships with foreign input suppliers. Some of this is due to a technology effect: any given producer would have higher variable profits from operating the technology using imported intermediate goods. To account for the roles of these theoretical mechanisms, we develop a simple model of a competitive small open economy in which heterogeneous firms endogenously decide whether to use imported intermediate goods. The technology that uses imported intermediate goods is superior but requires a higher fixed cost of operating. The calibrated model captures the large performance advantage of importers and quantifies the selection and technology effects.     

Unemployment dispersion and the allocative efficiency of the labor market

An idea that seems to gain recurrent popularity in the economics profession is that, because of technological change, changes in consumer demand, skill mismatches, and the like, the unemployed tend to become concentrated or trapped in particular geographic areas and that for these reasons unemployment rates have grown more disparate over time. This paper examines the theoretical conditions necessary for the above argument to hold and shows that such conditions are not consistent with the notion of a competitive labor market. The paper then examines various measures of unemployment-rate dispersion in order to determine whether or not unemployment rates have indeed drifted further apart over time. The empirical evidence presented indicates unequivocally that geographic unemployment rates are neither more nor less dispersed now than they were twenty years ago. The results, therefore, suggest that the competitive view of the labor market is appropriate and that the hypothesis that unemployment rates have become more dispersed over time because of structural imperfections in the labor market should be rejected.     

Absenteeism,Efficiency Wages,and Marginal Taxes

In this paper, I test the argument that increased taxes on earnings correspond to increased incentives to shirk, thus causing an increase in the rate of worker absenteeism. After fixed job effects are taken into account, panel register data on prime‐age Norwegian males who work full‐time show that a higher marginal net‐of‐earnings‐tax rate reduces the rate of absenteeism. When the net‐of‐tax rate is increased by 1.0 percent, absenteeism decreases by 0.3?0.5 percent. Injury‐related absences are less affected by tax changes than other absences. Absenteeism becomes more sensitive to tax changes as the occupational unemployment rate increases.     

The Effect of the Interaction between Price and Time Preference on Cigarette Consumption among Pregnant Women

In this study, I explore smoking behavior among pregnant U.S. women using the 1979 cohort of the National Longitudinal Survey of Youth. The key aspect of this study is the availability of smoking participation data before and during pregnancy. I consider the probabilities of smoking cessation while pregnant as the outcome. I find that pregnant women who smoke are less responsive to price changes when they are more future-oriented. Women who are more present-oriented are more likely to smoke and consume more cigarettes given that they smoke more than those who are future-oriented. Moreover, those who discount the future more heavily are more sensitive to the money price of cigarettes than those who are more future-oriented. I focus on the role of time preference and the interaction between time preference and price in determining these outcomes.     

The governance structures of Japanese credit associations and their objective functions

Although Japanese credit associations are non-profit cooperative financial institutions, they assume the same financial functions as regional banks that are stock companies and they could compete with each other in a regional market. On the other hand, the governance structures of credit associations tend to exhibit weaker discipline than those of regional banks, and, for this reason, the financial performances of credit associations and regional banks might differ. In this article, we empirically investigated whether the objective functions of credit associations are different from those of regional banks considering their different governance structures. As a result, although significant differences of profitability of these two types of institutions were not detected, it was demonstrated that credit associations can capture a greater share of deposits than regional banks and the former are more conservative in risk taking than the latter. From these, there is a possibility that Japanese credit associations have different objective functions from regional banks.     

You can’t always get what you want: gender differences in job satisfaction of university graduates

Previous literature stressed on the gender differences in job satisfaction and the factors influencing the job satisfaction of men and women. Two rationales are usually provided for the finding that women tend to be relatively more satisfied with their jobs than men although disadvantaged in labour markets: first, women may have relatively lower expectations of career and income, and second, they may attach relatively less importance to extrinsic rewards than men. In order to analyse whether substantial gender differences exist already at the beginning of the career, we employ information of over 20 000 graduates collected through a large-scale survey of German university graduates who recently entered the labour market. We find that the job satisfaction of female graduates is on average slightly lower than the job satisfaction of male graduates, but our results do not point to substantial gender differences. In our sample of highly qualified individuals, men and women are very similar in what they want from their jobs and also in their perceptions of what they get. While our results point to substantial similarity of men and women in the early career stage, gender differences may emerge at later stages of the career life cycle.     

AGE AS A DETERMINANT OF LABOR'S TRADE POLICY INTERESTS

This paper shows that workers with identical innate abilities have heterogeneous trade policy interests, whereby age of the worker and industry of employment are most critical in explaining this heterogeneity. A modified specific factor model, with overlapping generations and a retraining requirement for job switchers, is developed to demonstrate how trade policies affect the economic interests of older workers far more than of younger workers, regardless of whether they gain or lose from the policy. Accordingly, older workers tend to have stronger incentives to become politically active than younger workers.     

Taxes,Competition and Finance for Albanian Enterprises: Evidence from a Field Study

This paper analyses the results from a survey, carried out in 1999, of more than 100 enterprises in Albania. The main finding of the survey is that registered businesses regard competition from the informal sector as the most important problem they face in doing business. Unregistered firms have a significant advantage because they are able to evade the relatively high tax burden. Poor access to loans is also a significant obstacle. Enterprises tend to rely on own sources of funds for business start-up expansion. Larger enterprises are more likely to apply for loans than smaller ones, but having applied, are no more likely to be successful.     

Who takes the child to the doctor? Mom,pretty much all of the time

We document the degree to which Danish mothers are responsible for handling their children’s medical services. Using unique administration data on detailed medical services that were performed on all Danish children from 1992 to 1995, we find that, on average, more than 90% of all children’s medical services were handled by their mothers rather than their fathers. To our knowledge, this is the first study to use medical register data to quantify domestic time use. As these services are mainly performed during work hours, this finding provides one mechanism by which absenteeism increases as a consequence of motherhood. Furthermore, the economic variables that should affect a household’s assignment of a task like taking the child to the doctor are shown to explain very little, suggesting that other factors, such as societal norms, are at play.     

Solving coordination failure with “all-or-none” group-level incentives

Coordinating activity among members is an important problem faced by organizations. When firms, or units within firms, are stuck in bad equilibria, managers may turn to the temporary use of simple incentives—flat punishments or rewards—in an attempt to transition the firm or unit to a more efficient equilibrium. We investigate the use of incentives in the context of the “minimum-effort,” or “weak-link,” coordination game. We allow groups to reach the inefficient equilibrium and then implement temporary, flat, “all-or-none” incentives to encourage coordination on more efficient equilibria. We vary whether incentives are positive (rewards) or negative (penalties), whether they have substantial or nominal monetary value, and whether they are targeted to a specific outcome (the efficient equilibrium) or untargeted (apply to more than one outcome). Overall, incentives of all kinds are effective at improving coordination while they are in place, but there is little long-term persistent benefit of incentives—once incentives are removed, groups tend to return to the inefficient outcome. We find some differences between different kinds of incentives. Finally, we contrast our results to other recent work demonstrating greater long-term effectiveness of temporary incentives.      

Testing the rational expectations and structural neutrality hypotheses: Some further results for the U.K.

In this paper we test directly for the restrictions implied by rational expectations and structural neutrality. The tests are direct in the sense that they employ theLucas output equation father than the approximations to it, which replace the lagged output term by lagged monetary shocks, commonly considered in the literature. The direct approach is considered preferable because it avoids these ad hoc approximations and saves significantly on degrees of freedom. The latter permits us to pursue a fully nested testing procedure, which was not possible in earlier work employing postwar U.K. annual data. The main result is that the rational expectations restrictions are not accepted.
