“Understanding Relationships Using Copulas,” by Edward Frees and Emiliano Valdez,January 1998

Presenteeism occurs when employees are present at the workplace but cannot perform at their best because of ill-health or other reasons, while absenteeism occurs when employees are absent from the workplace. Although absenteeism is important, researchers now say presenteeism can be more costly to businesses and may be responsible for as much as three times the health-related lost productivity as compared to absenteeism and may cost the U.S. economy as much as $150 billion per year. Given the cost of absenteeism and presenteeism, one of the objectives of this article is to provide actuaries with the techniques and insights needed to design disability insurance policies that take into account the dynamics of absenteeism and presenteeism. To this end we develop a simple multistate sickness-disability model of the evolution of an employee’s health over time. We assume employees receive sick pay, the size of which depends on their health state, and there is a government-sponsored unemployment insurance program. In our model it is possible for employees in good health to avoid work by staying home, which is called shirking. To reduce shirking, the employer decides to check the health status of a certain percentage of employees who “call in sick.” Given the sick-pay structure, the probability of a health check, and the existence of unemployment insurance, employees develop rational strategies about whether to engage in shirking, absenteeism, or presenteeism. These strategies are captured in a set of Volterra integral equations. We use these Volterra integral equations to show how the employer can design a disability insurance plan that can incentivise employees to eliminate shirking and to act in a manner that will maximize the employer’s expected profits.     

Kongruente Rückdeckung von Pensionszusagen durch Versicherungsprodukte

When a German employer establishes a defined benefit pension plan for his employees, it is common practice in Germany to purchase life insurance policies in order to finance the plan and transfer the risks from the plan to the insurer. A complete transfer of risk can only be obtained by purchasing a congruent insurance policy. The present paper develops a formal definition of congruence of an insurance policy to a pension plan. The definition is applied to a simple practical example. It becomes clear that it is almost impossible to obtain congruence of a traditional German life insurance product to an employer's defined benefit pension plan.     

Measuring Longevity Risk: An Application to the Royal Canadian Mounted Police Pension Plan

An employer that sets up a defined benefit pension plan promises to periodically pay a certain sum to each participant starting at some future date and continuing until death. Although both the future beneficiary and the employer can be asked to finance the plan throughout the beneficiary's career, any shortcoming of funds in the future is often the employer's responsibility. It is therefore essential for the employer to be able to predict with a high degree of confidence the total amount that will be required to cover its future pension obligations. Applying mortality forecasting models to the case of the Royal Canadian Mounted Police pension plan, we illustrate the importance of mortality forecasting to value a pension fund's actuarial liabilities. As future survival rates are uncertain, pensioners may live longer than expected. We find that such longevity risk represents approximately 2.8 percent of the total liability ascribable to retired pensioners (as measured by the relative value at risk at the 95th percentile) and 2.5 percent of the total liabilities ascribable to current regular contributors. Longevity risk compounds the model risk associated with not knowing what is the true mortality model, and we estimate that model risk represents approximately 3.2 percent of total liabilities. The compounded longevity risk therefore represents almost 6 percent of the pension plan's total liabilities.     

Spin‐outs: knowledge diffusion through employee mobility

In many industries, one important method of diffusion is through employee mobility: many of the entering firms are started by employees from incumbent firms using some of their former employer's technological know‐how. This article explores the effect of incorporating this mechanism in a general industry framework by allowing employees to imitate their employers' know‐how. The equilibrium is Pareto optimal because the employees “pay” for the possibility of learning their employers' know‐how. The model's implications are consistent with data from the rigid disk drive industry. These implications concern the effects of know‐how on firm formation and survival.     

Furloughing*

Over nine million jobs were furloughed in the United Kingdom during the coronavirus pandemic. Using real-time survey evidence from the UK in April and May 2020, we document which workers were most likely to be furloughed and we analyse variation in the terms on which they furloughed. We find that women were significantly more likely to be furloughed. Inequality in care responsibilities seems to have played a key role: mothers were 10 percentage points more likely than fathers to initiate the decision to be furloughed (as opposed to it being fully or mostly the employer's decision) but we find no such gender gap amongst childless workers. The prohibition of working whilst furloughed was routinely ignored, especially by men who can do a large percentage of their work tasks from home. Women were less likely to have their salary topped up beyond the 80 per cent subsidy paid for by the government. Considering the future, furloughed workers without employer-provided sick pay have a lower willingness to pay to return to work, as do those in sales and food preparation occupations. Compared with non-furloughed employees, furloughed workers are more pessimistic about keeping their job in the short to medium run and are more likely to be actively searching for a new job, even when controlling for detailed job characteristics. These results have important implications for the design of short-time work schemes and the strategy for effectively reopening the economy.     

The price of fear: Estimating the financial cost of bullying and harassment to the NHS in England

Using a spectrum of measures, this paper estimates some of the financial costs of bullying and harassment to the NHS in England. By means of specific impacts resulting from bullying and harassment to staff health, sickness absence costs to the employer, employee turnover, diminished productivity, sickness presenteeism, compensation, litigation and industrial relations costs, we conservatively estimate bullying and harassment to cost the taxpayer £2.281 billion per annum.     

Health plan termination--bankruptcy--automatic stay--COBRA. In re Health Management Limited Partnership

Even though an insurer provided telephone notice of termination of a group health plan's insurance coverage for failure to pay the required premium on the same day the employer filed a bankruptcy petition and gave written notice after the petition was filed, it did not violate the bankruptcy code's automatic stay provision. This is because a special payment plan provided for an extended grace period and automatic termination upon failure to pay the premium in full by the end of that period, and the final due date was before the debtor filed the petition. Thus, termination occurred automatically before the bankruptcy petition was filed. The insurer is not the plan administrator and is not obligated to provide COBRA notice to the debtor's employees, especially since the employees could not elect to continue coverage under a group health plan when the insurance coverage had been terminated. An employee's right to elect to continue coverage under the employer's group plan presumes there is coverage available to continue.     

Changing employee values: deepening discontent?

This article presents a synthesis of data on employee attitudes gathered over the last 25 years. Most of the findings confirm the hypothesis that employees are discontented and expect more from their jobs now than they have in the past. While managerial satisfaction has remained relatively constant, the work satisfaction among hourly and clerical employees has sharply decreased. The authors attribute dissatisfaction to changes in the expectations and values of employees and warn that the deterioration of work attitudes may result in increased operating costs due to poor quality work, reduced output, absenteeism, etc. Instituting an employer attitude survey is suggested as a means of improving communication between management and employees and increasing job satisfaction.     

Potential measures and expected present value of operating costs until ruin in renewal risk models with general interclaim times

In this paper, a Sparre Andersen risk process with arbitrary interclaim time distribution is considered. We analyze various ruin-related quantities in relation to the expected present value of total operating costs until ruin, which was first proposed by Cai et al. [(2009a). On the expectation of total discounted operating costs up to default and its applications. Advances in Applied Probability 41(2), 495–522] in the piecewise-deterministic compound Poisson risk model. The analysis in this paper is applicable to a wide range of quantities including (i) the insurer's expected total discounted utility until ruin; and (ii) the expected discounted aggregate claim amounts until ruin. On one hand, when claims belong to the class of combinations of exponentials, explicit results are obtained using the ruin theoretic approach of conditioning on the first drop via discounted densities (e.g. Willmot [(2007). On the discounted penalty function in the renewal risk model with general interclaim times. Insurance: Mathematics and Economics 41(1), 17–31]). On the other hand, without any distributional assumption on the claims, we also show that the expected present value of total operating costs until ruin can be expressed in terms of some potential measures, which are common tools in the literature of Lévy processes (e.g. Kyprianou [(2014). Fluctuations of L'evy processes with applications: introductory lectures, 2nd ed. Berlin Heidelberg: Springer-Verlag]). These potential measures are identified in terms of the discounted distributions of ascending and descending ladder heights. We shall demonstrate how the formulas resulting from the two seemingly different methods can be reconciled. The cases of (i) stationary renewal risk model and (ii) surplus-dependent premium are briefly discussed as well. Some interesting invariance properties in the former model are shown to hold true, extending a well-known ruin probability result in the literature. Numerical illustrations concerning the expected total discounted utility until ruin are also provided.     

共享领导对员工创造力的“双刃剑”效应——心理安全感和角色压力的作用

运用工作资源-要求模型,基于心理安全感和角色压力的作用,考量共享领导对员工创造力的影响。结果表明,心理安全感在共享领导与员工创造力之间起正向中介作用（前后两半段路径均为正向）;角色压力在共享领导与员工创造力之间起负向中介作用（前半段路径均为正向,后半段路径为负向）。鉴此,管理者应密切关注共享领导实施过程中的员工心理安全感建设,激发出共享领导对员工创造力的积极效应     

A Termination Rule for Pension Guarantee Funds

A termination rule based on a critical funding ratio is proposed for a pension guarantee fund (PGF) that considers closing an underfunded pension plan. This ratio is determined by solving an expected utility maximization problem on behalf of plan beneficiaries subject to two constraints designed to preserve the PGF's viability. The first is an upper bound on the PGF's annual intervention probability; the second, a restriction on the expected shortfall of an underfunded pension plan that is not closed. Both too low and too high critical funding ratios hurt beneficiaries’ interests, depending on their degree of risk aversion.     

竞业限制法律制度完善研究

竞业限制法律制度需要完善其效力要件和履行机制.竞业限制法律制度已经确认合理性原则,经济补偿应属于竞业限制协议的效力性要件,没有约定经济补偿的竞业限制协议应当无效.劳动合同的解除方式不应对竞业限制协议的效力产生影响.我国劳动合同法应当建立劳动者单方选择权的法定抗辩制度,不应赋予用人单位对于竞业限制协议的单方任意解除权.劳动者承担违约金责任后,不应再负担继续履行的义务.     

The Influence of Culture on Pension Plans

It is widely recognized that culture is a dimension affecting a vast array of management and social choices. However, we know little about the effect of culture on choices that combine both business and social issues in an accounting setting. Employee benefit choices by managers reflect both the business choices of a firm in the selection and retention of employees and social choices in the type and extent of benefits provided to employees. The objective of this study is to investigate the extent to which culture affects employee benefits as manifested in pension plans. In a comparison of plans that differ according to the home country of the parent firm and are offered in the regulated environment of the United States, results indicate an effect of culture on pension plan choices. In particular, culture plays a role in determining the funding level percentage of the plan, employer contributions receivable, and revenues received or receivable from employers.     

Designing and managing employer-sponsored long-term care plans

Due to prevalent demographic factors, long-term care is an issue of increasing concern to American workers. The cost and time involved in ever-expanding long-term care responsibilities for many employees has resulted in increased indirect employer costs. The authors argue that providing' long-term care as part of the employee benefit plan is an efficient and effective way to manage these increasing costs for both the employer and the employee. The article offers discussion of plan design for long-term care, including issues to be considered and strategy for plan management.     

The timing of pay

There exists large and persistent variation in not only how, but when employees are paid, a fact unexplained by existing theory. This paper develops a simple model of optimal pay timing for firms. When workers have self-control problems, they under-save and experience volatile consumption between paychecks. Thus, pay whose delivery matches the timing of workers' consumption needs will reduce wage costs. The model also explains why pay timing should be regulated (as it is in practice): although the worker benefits from a timing profile that smoothes her consumption, her lack of self-control induces her to attempt to undo the arrangement, either by renegotiating with her employer or by taking out payday loans. Regulation of pay timing and consumer borrowing is required to counter these efforts, helping the worker help herself.     

PSYCHOLOGICAL CONTRACTS AND JOB SATISFACTION: CLUSTERING ANALYSIS USING EVIDENTIAL C‐MEANS AND COMPARISON WITH OTHER TECHNIQUES

The psychological contract refers to an individual employee's belief in mutual obligations between them and their employer. Psychological contracts are a key management concern, as they can impact employees' attitudes and behaviors in ways that influence organizational efficiency and effectiveness. In this paper, we analyse the relationship between the psychological contract and facets of job satisfaction among non‐profit sector employees, using the nascent non‐hierarchical evidential c‐means (ECM) clustering technique. To date, this technique has been theoretically discussed but not widely applied. Based on the Dempster–Shafer theory of evidence, ECM is novel in facilitating the assignment of objects, not only to single clusters, but to sets of clusters, and no clusters (outliers). The paper compares the theoretical underpinnings and findings from ECM with those of three other well‐known clustering techniques, namely (1) the hierarchical Ward's method, (2) the non‐hierarchical crisp k‐means and (3) the non‐hierarchical fuzzy c‐means approaches. We present and interpret the cluster solutions from each clustering technique. We establish three clusters differentiated by the content of the employees' psychological contracts. These clusters are validated by considering their relationship with facets of job satisfaction, to ensure the clusters are theoretically meaningful. Comparisons of the findings from each technique: (1) provide insights into the relationship between the psychological contract and job satisfaction; (2) reveal what ECM encompasses, relative to other clustering techniques; (3) inform the selection of an appropriate clustering technique for a specific research problem; and (4) demonstrate potential future directions in the development of cluster analysis.

Does Sensationalism Affect Executive Compensation? Evidence from Pay Ratio Disclosure Reform

Beginning in 2018, U.S. public firms were required to report the ratio of the chief executive officer's (CEO) compensation to their median employee's compensation in the annual proxy statement. Exploiting the staggered reporting of pay ratios, we find little evidence that total CEO compensation changes in response to pay ratio disclosure reform. However, we do find that boards significantly adjust the mix of compensation awarded by reducing the sensitivity of CEO pay to equity price changes, particularly when the CEO is likely to garner media scrutiny, and by reducing reliance on stock-based and other compensation components that are most susceptible to media coverage surrounding the pay ratio disclosure. Firms ultimately disclosing higher pay ratios garner more media coverage around the filing of their proxy statement, and more negative-toned coverage in the subsequent month. Finally, we find evidence that greater pay disparity is associated with greater selling activity by retail investors and more negative say-on-pay votes following pay ratio reform, consistent with a broad set of investors responding to public scrutiny resulting from pay ratio disclosures.     

Employee Costs of Corporate Bankruptcy

An employee's annual earnings fall by 13% in the first full calendar year after her firm's bankruptcy, and the present value of lost earnings from bankruptcy to six years following bankruptcy is 87% of pre-bankruptcy annual earnings. More worker earnings are lost in thin labor markets and among small firms. Ex ante compensating wage differentials for this “bankruptcy risk” are up to 2% of firm value for a firm whose credit rating falls from AA to BBB, comparable in magnitude to debt tax benefits. Thus, wage premia for expected costs of bankruptcy are sufficiently large to be an important consideration in capital structure decisions.     

What determines early exercise of employee stock options in Australia?

Employee stock options (ESOs) are a popular way of remunerating employees. We analyse factors at the firm and option level affecting the employee's decision to exercise ESOs before they mature. Exercises over the period 1998–2004 are analysed and the key factor influencing early exercise is found to be dividends. Exercises frequently occur well before maturity, but in most cases little time value is sacrificed. Our findings have implications for the ‘fair’ valuation of ESOs in companies’ financial statements, as required by the relevant Australian accounting standard, AASB 2.     

An analysis of changes to a team-based incentive plan and its effects on productivity,product quality,and absenteeism

Using data from three production units of a large manufacturing plant that employs production teams in its assembly operations, this paper examines how changes made to an existing team-based incentive plan affects labor productivity, product quality, and worker absenteeism. The firm switched from a piece-rates contract and an attendance bonus and instituted a two tier incentive plan comprising two different but complementary performance-based bonus schemes: one tier based on individual team performance and the other tier on plant-wide performance. The incentives were introduced concurrently with management control initiatives intended to facilitate cooperation and monitoring among the teams. I find significant productivity gains and improvements in quality and absenteeism associated with the new incentive plan. These findings underscore two important points that have not been emphasized in existing empirical studies of incentive pay: incentive contracts for teams generate superior performance using combination of incentives, and the need to introduce organizational changes to facilitate cooperation and peer monitoring in tandem with incentive pay to capture greater incentive effects in team production.
