Overtime Work and Overtime Compensation in Germany

Sharing the available stock of work more fairly is a popular concern in the public policy debate. One policy proposal is to reduce overtime work in order to allow the employment of more people. This paper suggests that such a concept faces major problems. Using Germany as a case study, it is shown that the group of workers with the highest risks of becoming unemployed, namely the unskilled, also exhibit low levels of overtime work. Those who work overtime, namely the skilled, face excess demand on the labour market. Since skilled and unskilled workers are largely complements in production, a general reduction in overtime will lead to less production and hence also to a decline in the level of unskilled employment. The paper provides empirical support for this line of argument. It is also shown that paid overtime work has lost relative importance over time.     

Marginal Ethos and the Just Price

The century-long decline in the amount of time spent working for income has been reversed over the last twenty-five years. By one account, this reversal is primarily traceable to a rise in the power fo employers who find more work hours per employee to be in their interest. By another account, that I argue to be the more convincing, the major cause of the change is the growing sophisticated of advertising and marketing which has stimulated demand and led to voluntarydecisions to work more. Education is presented as an example of the effects that rising “marketization” has on a product's nature. Decreased hours of study and grade inflation are offered as two examples of the crowding out of production for oneself at the expense of production for sale in the market. While no attempt is made to draw clear normative conclusions regarding educational trends, the paper concludes with a normative assessment of the trend toward greater time spent in the workplace. I argue that the historically recent rise of “workaholism” suggests that for at least a portion of the workforce, market forces have created preferences to work more that are ranked lower than what they replace; that the overworked American is too often one in the grip of an unpreferred preference regarding work.     

OVERTIME WORK AS A SIGNALING DEVICE†

This paper provides an explanation for the empirically proven relationship between overtime and future benefits. We suggest an internal signaling model, in which a worker signals his value to the employer by supplying unpaid overtime. In our empirical analysis, we examine whether overtime has in fact a signaling component. Variations in collectively bargained hours between industries are exploited, as they imply different overtime thresholds for workers with the same number of actual hours. Using data from the German Socio‐Economic Panel Study for the years 1993–2004, a positive signaling value of unpaid overtime is found for West German workers.     

Returns to workers and hours in finnish manufacturing

Production functions, where the number of workers, their average standard hours, and average overtime hours appear as separate inputs, are estimated using pooled data from Finnish industries. The results show that the returns to workers are higher than the returns to average hours and both returns are below one. This is in accordance with the assumption usually made in theoretical analyses of the demand for workers and hours. The productivity of overtime hours is slightly higher than that of standard hours. All the output elasticities are, however, fairly close to each other. Diagnostic tests show that there is collinearity between the explanatory variables, but application of several adaptive ridge estimators shows that this has not affected the results much.     

Trade liberalization and the Labor Market Revisited

This paper provides new insights in understanding the adjustments of the labor market to trade liberalization policies in an economy producing tradeables and nontradeables. The results of the paper indicate that the short-run effects of trade liberalization on wages, labor allocation and worker welfare is contingent on certain explicit production and demand conditions that exist in an economy. The production condition is related to the slope of the labor demand curve in a given economy and the demand condition is related to the difference in the cross-price elasticity of demand of nontradeables to the price of importables and exportables. The necessary combination of these conditions needed for trade liberalization to be welfare improving in the short run is explored.     

Dynamic effects of labor supply: A mechanism explaining cross-sectional differences in hours

This paper first establishes the empirical fact that over the last quarter of the 20th century, the average weekly hours worked increased for workers in the highest wage quintile while it decreased for the ones at the lowest. In 1976, a worker in the lowest quintile worked 2.8 hours more per week than a high wage worker (worker in the highest quintile), but by 2006, the low wage worker worked 1 hour less. During this period, there was also a wide increase in wage inequality. The typical mechanism in which hours are only determined by contemporaneous wages cannot simultaneously explain the pattern found in both variables for every quintile.This paper attempts to reconcile these cross-sectional trends in both hours and wages for the US during this time period. As a first step, we show that compositional changes (in education, occupation and age) within quintiles can only explain a fraction of the observed pattern. Next, we propose a mechanism in which individuals' current decisions of how much to work take into account two components: the contemporaneous benefit of the wage received, and also how current hours worked affects the probability of moving across the wage distribution in later periods. The latter dynamic component is estimated from our dataset. We find that changes over time in how hours affect these probabilities provided incentives that differ across the quintiles, and are consistent with the labor supply decisions observed in the data. We incorporate these two components into an equilibrium model of heterogeneous agents with uninsurable income risk. We are able to replicate the decline in hours for the bottom of the distribution as well as the increase at the top. The ratio of hours worked between the two groups delivered by the model also fits the trend found in the data.     

Definition of full-time and part-time employment,and distributional assumptions: the implications for the estimated full-time and part-time wage equations

This paper demonstrates that rejecting the standard definition of full-time and part-time workers, the estimated number of hours that an individual is likely to work as a full-time worker is a function of the type of distribution one assumes about the error term in the wage equation. Adopting a switching regression model with unknown sample selection, we have found that the normality assumption generates higher hours for full-timers in comparison with the non-normal distributions. We also noted that regardless of the distribution assumed, the hours differ from one industry to another. The implication is that the standard definition of full-time and part-time worker may not be appropriate for all firms irrespective of the distribution assumed. The paper also shows the sensitivity of parameter estimates to the distributional assumptions about the error term in the wage equation. The results indicate that the normal distribution wage equation estimates are relatively larger than the Weibull and exponential distributions. This finding is particularly important because such differences in estimated coefficients may have a direct wage influence on the wage gap between full-time and part-time workers across distributions.     

Working time, employment, and work sharing: Evidence from Sweden

We study three questions which are important for work sharing to increase employment. First, is there a negative long-run relation between working time and employment? Second, are hours per worker exogenous with respect to wages and employment? Third, can policy makers influence actual hours per worker? We formulate a theoretical model for employment, hours per worker, production, and real wages. A VAR model with cointegrating constraints is estimated by maximum likelihood using Swedish private sector data 1970:1–1990:4. We find (i) no long-run relation between hours per worker and employment, (ii) that hours per worker are endogenous with respect to the estimation of long-run parameters, and (iii) that legislated working time and hours per worker are related to each other in the long run.

The effects of works councils on overtime hours

This study analyzes the relation between works councils and overtime hours in Germany. The estimated effects differ considerably in dependence of standard contracted working time. Furthermore, we find differences across the quantiles of the overtime hours distribution and these differences between quantiles also vary between employees of establishment with and without works councils. By considering contracted working time effects and comparing conditional quantiles we find in some quantiles that employees of establishments with a works council have a higher amount of overtime hours if an employee regularly works 35 hours per week. This effect diminishes with increasing quantiles of the distribution of overtime hours. If an employee of a codetermined establishment regularly works 40 hours per week, overtime hours are reduced. This reduction becomes larger if higher quantiles are analyzed.     

The impact of Sunday shopping on employment and hours of work in the retail industry: Evidence from Canada

Between 1980 and 1998 every Canadian province passed legislation that in some way relaxed restrictions on Sunday shopping. This study exploits the variation in deregulation dates between provinces to identify how retail employers adjust employment and hours of work when deciding to open on Sundays. A major complication of this analysis is to first determine for which provinces the deregulation dates are useful indicators of increases in Sunday store openings. This paper uses a unique trading-day regression approach to identify these provinces and then uses aggregate data from the selected provinces to estimate a simple dynamic labour demand model that allows employment and hours to be imperfect substitutes in production. The results suggest that retailers’ needs for Sunday labour were disproportionately satisfied through increases in employment levels. Comparison of the estimates at three levels of the retail industry suggests that the employment and hours gains were larger among general merchandise stores than among more specialized retail establishments and relatively modest at the aggregate retail industry level. In addition, despite evidence of an immediate shortfall in the employment level below the long-run optimal level, the results suggest that firms were unable to compensate by temporarily increasing the hours of their existing employees.     

Labour Mobility With Vocational Skill: Australian Demand and Pacific Supply

Can new channels for mid-skill labour mobility simultaneously enhance the welfare of Australia and the Pacific Region? Answering this question requires forecasting Australian demand for vocationally-skilled migrants over the next generation, and the potential for Pacific supply of those migrants. We project demand for such mid-skill migrants over the next three decades by combining data on trends in the demand for basic tasks with data on trends in native investment in education commensurate with those tasks. We estimate that the Australian economy growing at historical rates through the year 2050 will demand approximately 1.6–2.1 million foreign workers with Technical and Vocational Education and Training. A large share of these could be supplied from the Pacific Islands with sufficient investment in training, with direct cooperation from Australian employers, and targeted access to the Australian labour market.     

Ethnicity and Job Tenure in a Segmented Labour Market: The Case for New Zealand

The labour market experience of 1984–1992 turned on end the prevailing notion of 'personal security' within New Zealand, founded as it was upon guaranteed employment (and full-employment in the aggregate). This study examines, in a systematic fashion and within a dynamic setting, why job tenure varied consistently over this period between two ethnic groups, the first comprised of European/Pakeha workers, and the second New Zealand Maori and Pacific Islanders.
Econometric analyses of total, voluntary and involuntary separations indicate that the low relative job security of Maori/Pacific Islanders cannot be attributed solely to differential attributes that, on the one hand represent such individuals' gender/age distribution, qualifications, and conditions of employment, and on the other provide controls for the relative competitive positions of their employers. Rather, other factors, such as worker segmentation, are likely operative within the New Zealand labour market, conditions that, on net, work to the disadvantage of non-Europeans.     

Employment security and the demand for labour in Europe

This paper analyses the impact of employment security on labour demand. The approach taken is to estimate a dynamic labour demand function that allows for the effect of changes in a measure of employment security derived from surveys of employers. The estimation uses panel data on employment (both in terms of the total number of employees and total hours worked) for seven European countries for the period 1981–1994. The results suggest that employment security can have significant effects in slowing down the dynamic adjustment of labour demand. The paper also finds some (less robust) evidence that employment security can increase the long run level of labour demand in terms of total hours, but not the number of persons employed.     

Men earn less under working time accounts: a puzzle?

In recent years more and more working time accounts (WTA) have been introduced. From a theoretical perspective both employers and employees benefit from such an instrument. Indeed, empirical studies show that life satisfaction of workers is larger under a WTA regime than under a non-WTA regime. However, more detailed investigations in this article reveal wages to be lower for men under WTA regimes. Why should men accept WTA when they earn less? Subgroup analyses show that these results are only valid for some groups of individuals. Our analysis allows us to deliver some explanations and to exclude other possible reasons. The major results are: (1) High-income workers suffer higher losses; (2) the shorter the compensation period of WTA systems the lower the wage reduction imposed by WTA; (3) the length of total working time does not seem to affect the link between WTA and wages but the length of overtime; (4) men accept wage losses from WTA if they can adjust actual to desired working hours.     

Financial Distress and Underemployment

A reasonable model of the labour market over the business cycle should predict, among other things, that (a) in very low states of product demand there may be too little employment from an efficiency perspective, but as the state improves employment will increase until ultimately it is efficiently deployed, and (b) in low states of demand, a worker's welfare level will be "low" and as the state of the world improves so will the worker's welfare, except, possibly, at high levels of demand where the worker's utility may start to fall. Surprisingly, there does not exist a labour contract based model that is consistent with predictions (a) and (b). In fact, the standard results in the literature are if leisure is a normal good then there will be too much employment in essentially all states of the world and the welfare of the worker declines as the state of the world improves. In this paper a labour contracting model is constructed that is consistent with the above mentioned predictions. Two necessary ingredients in the model are the possibility of financial distress in low demand states and "partial provability" in contracting. Financial distress can be viewed as frustrating renegotiation and, thus, inefficient outcomes are possible in equilibrium. Partial provability_the ability of an informed player to make verifiable claims or statements to an uninformed player_eliminates certain kinds of inefficient outcomes. In particular, it eliminates the possibility that, in equilibrium, there is too much employment. This last result is interesting in itself because it is commonly believed that normality of leisure necessarily implies that labour contracting models will generate employment levels that are too high from an efficiency perspective.     

Import Competition and Worker Productivity in Unionized Firms

This paper analyzes the effects of trade and labor market liberalization on wages and worker productivity/effort in a domestic unionized firm with firm-union bargaining over wages and effort. It is shown that both types of liberalization will induce a 'cold shower effect' (a rise in effort) if the union's objective function is more heavily weighted towards employment. However, the welfare effects of the two policies can differ markedly. The paper also identifies a separate productivity cost of protection associated with the distortionary effect of protection on worker effort.     

Has the Affordable Care Act increased part-time employment?

We examine the impact of the Affordable Care Act (ACA) on part-time employment. Because the ACA’s employer health insurance mandate applies to individuals who work 30 or more hours per week, employers may try to avoid the mandate by cutting workers’ hours below the 30-hour threshold in order to avoid having to provide them with health insurance. Although the employer mandate only went into effect in 2015, many observers have argued that forward-looking employers began to shift towards a part-time workforce well in advance of the mandate. To test this hypothesis, we examine relative shifts across two categories of part-time workers (25–29 hours and 31–35 hours). We find some evidence of a shift from the 31–35-hour category into the 25–29-hour category after the passage of ACA in March 2010. However, that shift is not more pronounced among low-wage workers or among workers in industries and occupations most likely to be affected by the mandate. Thus, there is little evidence that the ACA has caused the shift across hours categories, or led to an increase in part-time employment. However, the ACA could cause a shift towards part-time work in the future as the mandate takes effect.     

A decomposition of training probabilities

The determinants of workers' training probabilities are analysed. A distinction is made between the unconditional probability that a worker is employed by a firm that provides any training opportunities at all, and the conditional probability that the worker receives training given that s/he works for a firm that provides training. For this analysis a censored version of the bivariate probit model is applied. The results indicate that establishment size, industry dummies, type of schooling, age and experience affect only the unconditional probability, whereas the type of labour contract, working hours and job level affect only the conditional probability. Years of formal schooling affect both probabilities; more highly educated workers are both more likely to work for training-providing firms and, given that they work for such a firm, to be selected for training programmes.     

Total work time in Spain: evidence from time diary data

Using detailed time-use data from 2002–03 and 2009–10 for Spain, we analyse changes in the time-allocation decisions of the Spanish population, with a focus on the time devoted to total work. Consistent with prior literature, we document that the concept of ‘iso-work’ (e.g. the time devoted to total work by gender is equal) does not hold in societies with stringent gender roles, such as Spain. Women devote more time to total work than men, and this difference has increased throughout the period studied by 2 hours per week. The relative increase in total work for women compared to men can be explained by a relative increase in market work of 8 hours per week, coupled with a relative decrease in nonmarket work of 6 hours per week, which have led Spanish women to devote, relatively, 2 fewer hours to leisure per week in 2009–10, compared to 2002–03. We propose social norms as a potential explanation of these empirical findings. By uncovering how individuals allocate their time inside and outside the market over a period of time, our results may improve our understanding of the dynamics of economic change and welfare.
