Job satisfaction and mental health of temporary agency workers in Europe: a systematic review and research agenda

ABSTRACT

The current systematic literature review aimed to analyse the associations between temporary agency work (TAW), job satisfaction, and mental health in Europe, as well as to outline a future research agenda. Twenty-eight scientific articles were identified by searching different data bases (i.e. PSYNDEX, PsycINFO, PubMed, and Web of Science) for the time span from January 2000 to December 2016. Our review reveals first that TAW is not consistently negatively related to job satisfaction. However, job insecurity and working conditions are important mediators in the relation of TAW and lowered job satisfaction. Second, TAW is not consistently related to all investigated types of mental health impairments. However, when focusing on specific outcomes and comparing temporary agency workers to permanent employees, we still find consistent evidence regarding higher levels of depression and fatigue among temporary agency workers. Inconsistent associations between TAW, job satisfaction and mental health can partly be attributed to unfavourable methodological aspects of the included primary studies. To address these aspects, future research should consider applying a standard measurement of TAW, including a minimum of meaningful confounding variables, improving the operationalisation of outcome variables and the study design.     

Explaining the Desire for Local Bargaining: Evidence from a Finnish Survey of Employers and Employees

Abstract. This paper describes divergences in employers’ and employees’ opinions on the proper share of local bargaining in contract wage gains in Finland. Employers want the locally bargained wage share to be approximately half of the total wage rise, while the majority of employees would prefer this share to be in the region of 1–24 per cent. Employers in firms that are large, foreign owned or operate in the financial services industry desire the largest locally bargained share of contract wages. Employees in large firms, on the other hand, resist local bargaining. When the firm uses performance‐related pay, employees would prefer a large role for local bargaining in contract wage gains.     

Education,Mobility and Employers’ Monopsony Power: A Search‐theoretic Analysis

Abstract. We analyse the efficiency of schooling choices in a wage‐posting search equilibrium model with on‐the‐job search. The workers have multidimensional skills and the search market is segmented by technology. Education determines the scope — or adaptability— of individual skills. Individuals obtain schooling to leave unemployment more quickly and to climb the wage ladder rapidly through job‐to‐job mobility — that is, to speed up job shopping. Education reduces firms’ monopsony power in the wage determination by improving workers’ mobility. As a result, the wage distribution shifts rightward with aggregate schooling. However, the ratio of vacant jobs to job seekers also falls in each sector. Either one or the other externality may dominate, implying, respectively, under‐ or over‐education. A combination of minimum wage and schooling fee can decentralize the efficient allocation.     

The Employment–Hours Trade‐off: Theory and an Application to the Portuguese Case

Abstract. Using traditional production theory, it is possible to estimate production functions in which hours per worker and number of workers hired are treated as endogenous and chosen by the firm, priced respectively by the variable hourly wage and the so‐called quasi‐fixed unit cost. The available data suggested the use of Cobb–Douglas or CES specifications or the use of two‐stage separable technologies, with a second‐level Cobb–Douglas being possible. Quasi‐fixed costs were associated with legal social security payments, which were also conditioned by the data. The estimates for the Portuguese metal products and engineering industries — using cross‐section evidence for 1987 — showed that disaggregation of the labor input is empirically justifiable, and total man‐hours employed and the numbers of workers hired are complements in production. Hours per worker respond negatively to the variable hourly wage and positively to the quasi‐fixed unit cost. Nevertheless, in our framework, this would be so by construction. Total labor costs increase with both the hourly wage and the quasi‐fixed unit costs.     

The Role of Family Ties in the Labour Market. An Interpretation Based on Efficiency Wage Theory

By casual empiricism, it seems that many firms take explicit account of the family ties connecting workers, often hiring individuals belonging to the same family or passing jobs on from parents to their children. This paper makes an attempt to explain this behaviour by introducing the assumption of altruism within the family and supposing that agents maximize a family utility function rather than an individual one. This hypothesis has been almost ignored in the analysis of the relationship between employers and employees. The implications of this assumption in the efficiency wage models are explored: by employing members of the same family, firms can use a (credible) harsher threat — involving a sanction for all the family’s members in case of one member’s shirking — that allows them to pay a lower efficiency wage. On the other hand, workers who accept this agreement exchange a reduction in wage with an increase in their probability of being employed: this can be optimal in a situation of high unemployment. Moreover, the link between parents and children allows the firm to follow a strategy that solves the problem of an individual’s finite time horizon by its making use of the family’s reputation.     

Technology Effects on Wages in Finnish Manufacturing

In this paper we study the effect of technology on establishment‐level wages using a classification of manufacturing industries based on four technology levels. The technology wage premiums are estimated separately for non‐manual and manual workers using wage equations with available control variables for plant and workforce characteristics (human capital) over the time period 1974–93. The results do not show a straightforward increasing relationship between a plant’s average wages and its technology at higher technology levels. However, establishments with the lowest technology level paid the lowest wages during the whole period. We also find that the relative non‐manual to manual wage ratio increased over the time period in the highest technology levels. These findings are consistent with technology wage premiums and skill‐biased technological change found in studies for other countries     

What Survey Data Reveal about Price and Wage Rigidity in Portugal

This paper exploits the information collected from a survey conducted on a sample of Portuguese firms to study the patterns of firms’ price and wage adjustments and the extent of nominal price and wage rigidities. The evidence shows that the frequency of price changes varies substantially across sectors and depends on the intensity of competition, the share of labor costs and firms’ price reviewing behavior. The results also suggest that the constraint imposed by the presence of downward nominal wage rigidity is less important in firms where the fraction of permanent and high‐skilled workers is lower and the share of flexible pay components is higher.     

Standard of Living as a Right,Not a Privilege: Is It Time to Change the Dialogue from Minimum Wage to Living Wage?

Dating back to the 1930s, President Franklin D. Roosevelt argued that workers were entitled to a wage that allowed them to enjoy a decent standard of living—a conviction that led the president to propose the first federally‐mandated minimum wage. Mr. Roosevelt’s proposal was met with highly partisan resistance in congress and the courts—reactions not different in kind from the highly partisan resistance former President Obama experienced in his proposal to increase the federal minimum wage from its current level of $7.25 per hour. Reflecting President Roosevelt’s convictions, it is clear that many low wage workers today are not, and cannot, enjoying a decent standard of living at current minimum wage levels. Further, many of the economic arguments raised in opposition to increasing the minimum wage have been thoroughly discredited: empirical evidence suggests that increased minimum wages would not lead to dramatic spikes in unemployment, massive substitutions of capital for labor, business closings, and significantly increased consumer prices. However, as compelling as arguments for increasing the minimum wage may be, the reality is that this may not be sufficient to alleviate the plight of low income workers, particularly given the political nature of minimum wage adjustments. Indeed, it may be time to shift the national focus away from the minimum wage to an emphasis on viable living wage legislation, a proposition consistent with the social justice perspective of contemporary ethicists.     

Preliminary Evidence on Wage Setting in Greek Manufacturing

Abstract. The negotiating power of the unions and their role in wage determination depends on the level of centralization of the wage bargaining system as well as on other institutional arrangements. In this study, we estimate a set of wage equations in order to study the employment effects of different unions’ stances in wage determination as well as to investigate other characteristics of employment in Greek manufacturing. We discriminate between workers and employees (blue‐ and white‐collar workers) and between sectors in order to capture differences in the relative supply as well as differences in the negotiating power among the staff of the same industry. Empirical findings reveal that the persistence of unemployment arises as a result of the great bargaining power of the unions in negotiations at a sectoral level. White‐collar workers exhibit a stronger negotiating power compared with blue‐collar workers because of differences in the institutional framework.     

Minimum Wages and Trainers' Dilemma

This paper examines how a minimum wage, viewed as an incentive to trainers, would affect the informal help provided through on‐the‐job training. In the work environment, experienced employees play a significant role in training new employees. However, the more help they provide to trainees, the less likely that the trainers themselves will be promoted. This is the trainer's dilemma: help trainees or work for promotion. We show that a minimum wage alleviates the trainer's dilemma, as it increases the earnings of non‐promoted workers and reduces the net benefit of promotion for experienced employees. Hence, minimum wage regulation encourages informal help and enhances welfare, although it reduces the firm's profit.     

Subjective Perceptions of Organizational Change and Employee Resistance to Change: Direct and Mediated Relationships with Employee Well‐being

Researchers have focused on linking objective measures of change exposure, such as the number of downsizing activities implemented, with employee well‐being. This has meant that less attention has been paid to employees’ subjective experience of change. The authors examine relationships between employees’ perceptions of the extent of change and the frequency of change and insomnia and psychological well‐being. They propose direct and indirect relationships via resistance to change between employees’ subjective experience of change and well‐being. Data were collected from 260 employees from a range of different organizations and industries. Respondents completed surveys at two time points, separated by four months. Results revealed significant indirect relationships between subjective perceptions of change and insomnia and employee well‐being via affective resistance to change at Time 1 and Time 2. In addition, employees’ subjective reports that change was very frequent were initially positively associated with T1 behavioral resistance to change but also were negatively associated with T2 behavioral resistance to change. Discussion focuses on the importance of managing employees’ perceptions of change. Practically, the authors consider the difficult choices that confront managers when seeking to implement and ‘sell’ change within their organization.     

Employment‐protecting Labour Market Institutions and Inward Foreign Direct Investments

Abstract. This paper proposes labour market institutional arrangements as a strategic device to induce or deter export‐substituting inward foreign direct investments (FDI) — in either instance protecting domestic employment. In a union‐oligopoly context it is shown that, if the FDI‐associated unit costs (FC) are not high enough, then employment‐neutral (‐enhancing) inward FDI will emerge in equilibrium if the domestic wage setting is credibly centralized and the unemployment benefit is sufficiently high (low), each instance arising for a different range of — intermediate — FC values. If however the FC values are sufficiently high, then the centralized structure of wage setting along with a low enough unemployment benefit will deter employment‐reducing inward FDI.

On the Dynamics of Unemployment and Wage Distributions

Postel‐Vinay and Robin's (2002) sequential auction model is extended to allow for aggregate productivity shocks. Workers exhibit permanent differences in ability while firms are identical. Negative aggregate productivity shocks induce job destruction by driving the surplus of matches with low ability workers to negative values. Endogenous job destruction coupled with worker heterogeneity thus provides a mechanism for amplifying productivity shocks that offers an original solution to the unemployment volatility puzzle (Shimer (2005)). Moreover, positive or negative shocks may lead employers and employees to renegotiate low wages up and high wages down when agents' individual surpluses become negative. The model delivers rich business cycle dynamics of wage distributions and explains why both low wages and high wages are more procyclical than wages in the middle of the distribution.     

The Implications of Temporary Jobs on the Distribution of Wages in Italy: An Unconditional IVQTE Approach

Using Italian data, this paper investigates the wage implications of temporary jobs across the whole pay profile using unconditional quantile regression (UQR) models. Results clearly indicate that the wage penalty associated to temporary jobs is significantly larger at the bottom of wage profile and is almost absent for high‐wage jobs. This is in line with the sticky floors hypothesis, supporting the idea that the wage gap for temporary employees depends on their position in the wage distribution for low‐paid jobs. To recover a causal interpretation, I employ an instrumental variable (IV) strategy. I adopt the unconditional instrumental variable quantile treatment effects (IVQTE) estimator proposed by Frolich and Melly, which corrects for endogenous selection in temporary contracts. The IVQTE estimates yield similar results to standard UQR, even if the wage penalty is larger in size at the bottom of the wage distribution and disappears at the top quantiles. This evidence highlights that policies aimed at increasing flexibility may reinforce the two‐tier nature of the Italian labour market and the relative wage inequality.     

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.     

Temporary/Permanent Workers' Wage Gap: A Brand‐new Form of Wage Inequality?

By easing restrictions on the use of short‐term contracts, the 30/2003 act represents contemporaneously the more extensive and the more radical policy aimed at introducing flexibility in the Italian labour market. By virtue of a difference‐in‐differences estimator, the paper provides an estimate of the impact of the 30/2003 reform on the wage gap across fixed‐term and long‐term employees. It will be given evidence that the policy has widened the wage differentials and the effect is particularly stronger to skilled workers compared with unskilled workers. These findings would suggest the existence of a possible brand‐new form of wage inequality.     

The Male–Female Wage Gap and the Firm Effect: The Case of Young Italian Workers

Abstract. The idea that wages are determined by firm and individual characteristics suggests that there is a firm effect that influences wage differentials. This paper presents the results of an empirical analysis of gender wage differentials — based on INPS data for people between the ages of 20 and 25 employed in the private sector in 1996 — which takes into account the characteristics of workers and firms using a two‐level random‐effects model. Firm variables proved to be significant, and the proportion of females in the firm showed a negative effect on the wages of both men and women.     

The Motherhood Wage Penalty and Its Determinants: A Public–Private Comparison

We investigate whether public and private sector employees bear a different wage penalty for having children. According to our estimates, the total motherhood wage penalty is much larger in the private than in the public sector. Nevertheless, in both sectors, we find no unexplained penalty once we control for potential determinants of the family pay gap, namely, a reduced labour supply of mothers, child‐related career interruptions, less access to management positions, and adjustments in working conditions. Finally, only child‐related career interruptions play a different role in explaining the motherhood wage penalty in each sector.
