Working time and labour demand in Finnish manufacturing: short-run and long-run effects

The effect of changes in the standard working time on employment and average hours is studied using pooled data from five Finnish manufacturing industries. The model is an error correction model, which makes it possible to separate short-run, reductions in standard hours increase employment. There is evidence that the long run effect of working time on employment has changed over time. In the 1970s reductions in hours have had positive long-run employment effects, but in the 1980s the positive short-run impact has been neutralized in the long run. Changes in standard hours do not influence the utilization rate of labour, which is defined as the ratio of overtime hours to standard hours. In the short run, the utilization rate is influenced by output changes.     

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.

Part–Time Work During Post–Compulsory Education And Examination Performance: Help Or Hindrance?

This paper examines the effects on examination performance of having a part–time job whilst in full–time post–sixteen education, using new data on young people in Northern Ireland. Around 35% engaged in part time employment during their education spell, compared to over 60% found by recent GB studies. This may be related to Northern Ireland's comparatively slack youth labour market and might reflect part–time employment levels in other peripheral regions. Our estimations suggest working part–time per se is not detrimental to examination performance, although working long hours is. Policy makers might improve educational performance by reducing incentives to work long hours.     

The trade-off between real wages and employment in an open economy (Belgium)

The purpose of this paper is twofold. First, we discuss the nature and quantitative order of magnitude of the trade-off between real wages and employment in the small open economy Belgium. Second, we draw policy conclusions from our positive analysis, and compare income policies with alternative approaches to employment stimulation (including shorter working hours and currency depreciation).To study the trade-off between real wages and employment, we treat external balance as a binding constraint on demand management. An exogenous increase in real wages, affecting adversely the competitiveness of domestic producers on the export and import markets, impairs external balance. The impact of the wage increase on output and employment is evaluated through the reduction in domestic demand required to restore external balance.At the empirical level, we endeavour to evaluate separately the influence on exports and imports of domestic costs at unchanged capacity levels, and of capacity levels themselves. And we endeavour to evaluate the influence of real wages on capacity levels through scrapping and investment. All evaluations rely on the foreign trade equations of econometric models of the Belgian economy.The conclusions from our empirical investigation are first that estimates of the trade-off between real wages and employment in Belgium are subject to considerable imprecision; second that the short-run elasticity of employment with respect to real wages keeping capacity constant is probably quite small (like -0.2), and definitely less than unity in absolute value; third that the corresponding medium-run elasticity taking into account capacity adjustments is probably sizeable (like -2), and definitely larger than unity in absolute value; and fourth that exchange rate adjustments might not make too much difference, in either the short run or the medium run.Turning to a discussion of policy, we shall argue that these conclusions give support to a policy of constant real labour incomes, of comprehensive efforts to redistribute work through shorter working hours or related schemes, and of selective efforts to slow down capacity scrapping.     

On the Use of the Prisoners' Dilemma to Analyze the Relations Between Employment Security,Trust, And Effort

Sociologists and political scientists have argued that the explanatory adequacy of economics is undermined by unreasonable assumptions of rationality. Yet interpretations that make strong rationality assumptions remain common. Analyses of the effects of employment security on work effort provide one example. The iterated prisoners' dilemma has been used to deduce a positive effect of employment security on work effort. Several difficulties with this approach are identified, including that the cooperative solution to the iterated prisoners' dilemma game i) requires infinite play or uncertainty about the end of the repetitions of the game; ii) is made less likely where there are structural bases for divergent interests; iii) ignores the possibility that employers might choose to shift the game to another arena. In general, there is the difficulty that employer-employee relations involve three simultaneous prisoners' dilemmas. The paper concludes that the hyper-rational approach implied in the prisoners' dilemma is an unpromising route for the analysis of the effects of employment security.     

Falling Labor Share and Rising Unemployment: Long–Run Consequences of Institutional Shocks?

The literature on unemployment has mostly focused on labor market issues while the impact of capital formation is largely neglected. Job creation is often thought to be a matter of encouraging more employment on a given capital stock. In contrast, this paper explicitly deals with the long–run consequences of institutional shocks on capital formation and employment. It is shown that the usual tradeoff between employment and wages disappears in the long run. In line with an appropriation model, the estimated values for the long–run elasticities of substitution between capital and labor for Germany and France are substantially greater than one.     

Is There a Causal Effect of Working Part‐Time on Current and Future Wages?

In this paper, I study the causal effects of part‐time work on current and future wages. To estimate these effects, I use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status. Exclusion restrictions from the institutional context are exploited to support identification. The results suggest that working part‐time with few hours has a large causal effect on current wages, but more extensive part‐time work does not reduce current wages. However, both types of part‐time work lead to negative long‐term wage effects.     

Income,happiness, and the disutility of labour

We re-examine the claim that the income effect on happiness is downward biased because higher income demands more work effort. We find no evidence of an underestimation because the impact of working hours on happiness is rather small and hill-shaped.     

The Causal Effects of the Minimum Wage Introduction in Germany – An Overview

In 2015, Germany introduced a statutory hourly minimum wage that was not only universally binding but also set at a relatively high level. We discuss the short‐run effects of this new minimum wage on a wide set of socioeconomic outcomes, such as employment and working hours, earnings and wage inequality, dependent and self‐employment, as well as reservation wages and satisfaction. We also discuss difficulties in the implementation of the minimum wage and the measurement of its effects related to non‐compliance and suitability of data sources. Two years after the minimum wage introduction, the following conclusions can be drawn: while hourly wages increased for low‐wage earners, some small negative employment effects are also identifiable. The effects on aspired goals, such as poverty and inequality reduction, have not materialised in the short run. Instead, a tendency to reduce working hours is found, which alleviates the desired positive impact on monthly income. Additionally, the level of non‐compliance was substantial in the short run, thus drawing attention to problems when implementing such a wide reaching policy.     

Wage Inequality,Increased Competition,and Trade Liberalization: Short Run vs Long Run

This paper examines the impact of increased competition and trade liberalization on skilled–unskilled wage inequality in the short run as well as the long run. It is shown that an increase in the number of firms in the producer services sector increases wage inequality in the short run even if the income shares of capital in the industrial and agricultural sectors were identical. A decrease in the services sector's fixed cost decreases wage inequality in the short run if the income share of capital in the agricultural sector is relatively large. Owing to the presence of external economies, a decrease in the services sector's fixed cost increases wage inequality in the long run. A decrease in import duty on the agricultural good increases wage inequality in the short as well as the long run but its effect in the long run is stronger due to the presence of external economies in the industrial sector.     

Is the Efficiency Wage Efficient when Workers Decide on the Working Time?

There is a body of literature that argues that workers' productivity is significantly influenced by their hours of work. This paper attempts to set up a shirking model of efficiency wages with endogenous working time to investigate how the endogenous working time decision critically influences work effort and undermines the efficacy of efficiency wages. We believe such a model might conceivably support the empirical finding that there exists a possibly perverse relationship between worker's effort and wages.

Employment and hours of work

This paper develops a dynamic model of the labor market in which the degree of substitution between employment and hours of work is determined as part of a search equilibrium. Each firm chooses its demand for working hours and number of vacancies, and the earnings profile is determined by Nash bargaining. The earnings profile is generally nonlinear in hours of work, and defines the trade-off between employment and hours of work. Concave production technology induces firms to overemploy and, as a result, hours of work are below their optimal level. The Hosios condition is not sufficient for efficiency. When there are two industries, workers employed by firms with higher recruitment costs work longer and earn more. That is, “good jobs” require longer hours of work. Interestingly, technology differentials cannot account for working hours differentials.     

Bargaining over effort

Employment contracts generally specify both the reward for labour and the conditions of employment. Although it is clear how unions affect the payment received by workers, the effect of unions upon working conditions, particularly the contracted effort level that must be supplied, is not so well-understood. This note analyses the generalised Nash bargain between a union and a firm over employment level and effort level. Under standard assumptions, it is shown that an increase in union power always leads to a reduction in the agreed effort level. The effect upon employment is dependent upon whether the firm has the ‘right-to-manage’.     

Chasing the carrot – actual working hours of fixed-term employees

Fixed-term contracts can serve as a screening device to reveal the true ability of workers. To achieve promotion to a permanent position, fixed-term employees have an incentive to prove themselves by providing higher effort than competing co-workers by means of longer working hours. Applying fixed effects estimation to the German register data, we find that employees work longer hours on fixed-term contracts. This effect is stronger for labour market entrants and employees that are newly hired. We further show that actual hours of work are particularly large when there is competition among co-workers to receive promotion to a permanent position.     

Advertising and labour supply: why do Americans work such long hours?

This paper advances the view that the intensity of creation of wants through advertising and marketing might be an influence on decisions made by Americans about how much time they should devote to paid work and how much time to leisure. In exploring this argument, we employ vector auto‐regression analysis to estimate long‐run supply schedules for US workers in the twentieth century. We find that advertising expenditure is significant in determining US hours of work, thus providing support for the hypothesis that preferences over work–leisure choices are malleable and are manipulated by the marketing effort.     

TAXATION AND CENTRALISED WAGE SETTING: THE CASE OF ENDOGENOUS LABOUR SUPPLY

The implications of centralised wage setting for the relationship between taxation, wages and employment are studied allowing for endogenous adjustment in work hours. We show that centralisation promotes wage moderation, makes wages and employment less sensitive to changes in wage taxation and reduces the hours worked. With an individual supply of working hours, a wage tax can even improve employment if wage setting is centralised and marginal utility from a public good is sufficiently high. Moreover, if a profit tax is used to finance public expenditure, higher tax reduces wages and improves employment.     

A wage-bargaining model for Denmark

Recent models of wage bargaining provide the background for formulating a wage-employment model which is estimated for the manufacturing sector in Denmark. Emphasis is laid on an interpretation of the empirical findings in a maroeconomic context. The major results are that wage setting is not characterized by money illusion, shorter working hours lead in the long run to full wage compensation and a fall in total number of hours worked, and expansionary demand management policies induce wage increases which eventually eliminate the expansionary effects on activity.     

After work shopping? Employment effects of a deregulation of shop opening hours in the German retail sector

This study investigates the impact of a deregulation of shop opening laws on employment in the German retail sector. Exploiting the gradual change in the opening times of shops across states and using data from the German Socio-Economic Panel, difference-in-differences estimates indicate an average increase in the employment probability, driven by a rise in the likelihood of working marginal part-time hours. Workers in small firms are likely to experience a reduction of their propensity to work. For individuals facing high family-related, supply-side constraints, the change in shop opening hours has opposing effects on employment — positive on lower and negative on upper parts of the hours distribution. Overall, the deregulation is estimated to have raised the likelihood of working fewer hours than desired by the workers.     

Doing it all: Women’s employment and reproductive work in Tajikistan

Central Asia has low labor force participation rates for women, despite high levels of poverty in the non-oil producing countries. Female labor force participation is related to competing uses for women’s time, especially in a context of poor infrastructure and limited availability of purchased replacements for household labor. We examine factors affecting women’s participation in employment and reproductive household work in Tajikistan, drawing on the 2003 Tajikistan Living Standards Survey. We incorporate specific conditions in Central Asia, including the prevalence of extended family households, norms about how women share household work, an absence of market substitutes for caring and reproductive labor, employment in family enterprises and poor infrastructure, especially in rural areas. We estimate the system using a Generalized Maximum Entropy (GME) approach. We find that few individual and household characteristics are related to time in employment. Time in noncare reproductive work decreases if a woman receives direct remuneration for her employment (compared to working in a family farm or enterprise but receiving no direct remuneration), but increases if the woman has less access to infrastructure. Rural women spend more time in both employment and non-care reproductive work than urban women, but less time in care work. Lack of infrastructure may leave women with few choices with respect to non-care reproductive work, while overall levels of time poverty create pressures on care time.
