Worktime control and work stress: the moderating effect of self-comparisons and social comparisons

Abstract

Perceived work-related stress has increased notably in recent years, reducing individuals’ well-being and increasing organizations’ and economies’ costs. This study focuses on worktime control as a key approach to reducing work stress, as the extant research on its effects reports inconsistent results. The study argues that comparisons play a major role in how work stress, conceptualized as effort-reward imbalance, occurs. Ordinary least squares is used to test hypotheses with a sample of 1721 employees from Germany to determine whether employees’ prior worktime control and employees’ referents’ worktime control affect the relationship between worktime control and work stress. Results show that (1) worktime control is negatively associated with the experience of work stress, (2) employees’ prior worktime control moderates the relationship between worktime control and work stress, and (3) there is no moderating effect of employees’ referents’ worktime control. The results are discussed in light of gift-exchange theory and related empirical findings.     

World economic slowdown

In the course of last year, the economic climate cooled down world-wide; it was placed under additional strain in late summer by the Gulf crisis. In some industrialized countries, especially the USA, recessive trends have recently gained prevalence. Do indications for 1991 therefore point to a downturn in the world economy?     

Inflation and output dynamics in a model with labor market search and capital accumulation

In a sticky-price model with labor market search and habit persistence, Walsh (2005) shows that inertia in the interest rate policy helps to reconcile the inflation and output persistence with empirical observations for the US economy. We show that this finding is sensitive with regard to the introduction of capital formation. While we are able to replicate the findings for the inflation inertia in a model with capital adjustment costs and variable capacity utilization, the output response to an interest shock is found to be too large and no longer hump-shaped in this case. In addition we find that the response of output to a technology shock can only be reconciled with empirical findings if either the adjustment of the utilization rate is very costly or there is only a modest amount of nominal rigidity in the economy.     

Testing time-homogeneity of rating transitions after origination of debt

When modelling rating transitions as continuous-time Markov processes, in practice, time-homogeneity is a common assumption, yet restrictive, in order to reduce the complexity of the model. This paper investigates whether rating transition probabilities change after the origination of debt. Accordingly, we develop a likelihood-ratio test for the hypothesis of time-homogeneity. The alternative is a step function of transition intensities. The test rejects time-homogeneity for rating transitions observed over 7 years in a real corporate portfolio. Especially 1-year transition probabilities increase over the first year after origination. This time effect suggests that banks should manage their credit portfolios with respect to the age of debt.      

Environmental problems in Belarus

Résumé By far the most pressing problbem facing Belarus is the radioactive contamination resulting from the accident at the Chernobyl nuclear power station and the on-going threat to the environment posed by the destroyed reactor and those blocks which continue to produce electricity. The country is clearly not in a position to cope with the repercussions of the disaster. Western aid is required here, particularly to provide medical care for the population, decontaminate polluted areas, provide reliable measuring equipment and to analyse the level of contamination in food supplies. Air pollution, although worrying in some cities, is not as dramatic as in most of the polluted industrial centres of Russia and the Ukraine. Water pollution, too, is less serious than in most of the successor states to the Soviet Union. A serious problem is, however, posed by salification of the water supply by the potash industry. Recently environmental charges were introduced with the aim of improving environmental protection. Yet given rapid inflation and the persistence of soft budget constraints for enterprises, such charges are unlikely to have so far provided a significant incentive to more ecologically sustainable production in Belarus.     

Downward wage rigidity and job mobility

Using data from the German Socio-Economic Panel (GSOEP) we study whether being individually affected by downward wage rigidity has an effect on layoffs, quits and intra-firm mobility. Within a structural empirical model we estimate the individual extent of wage rigidity. This is expressed by the wage sweep-up, which measures by how much individual wage growth increases through the effect of downward wage rigidity when compared to a counterfactual labour market with flexible wage setting. We find robust negative effects of wage sweep-up on quits and layoffs and some evidence for a positive association of wage sweep-up and promotion opportunities. This is consistent with a core-periphery view of the labour force, where a core work force is protected from layoffs and wage cuts and at the same time enjoys good promotion opportunities. On the other side a peripheral work force provides a buffer for adjustment and suffers from both flexible wages, more insecure jobs and less internal promotion opportunities.
