Profit Sharing and the Quality of Relations with the Boss

Profit sharing generates conflicting changes in the relationship between supervisors and workers. It may increase cooperation and helping effort. At the same time it can increase direct monitoring and pressure by the supervisor, and mutual monitoring and peer pressure from other workers that is transmitted through the supervisor. Using data on satisfaction with the boss, we initially show that workers under profit sharing tend to have lower satisfaction with their supervisor. Additional estimates show this is largely generated by groups of workers who would be least likely to respond to increased supervisory pressure with increase effort: women, those with dependents and those with health limitations. Despite this finding, profit sharing seems to have little or no influence on overall job satisfaction as the reduction in satisfaction with the boss is offset with increased satisfaction with earnings, a finding consistent with profit sharing enhancing productivity and earnings.

Does profit sharing increase training by reducing turnover?

We test the theoretical prediction that profit sharing reduces worker separations and by doing so increases the incidence of training. Using individual level UK data, we confirm that profit sharing is a robust determinant of lower separation rates and of greater training incidence. Critically, we cannot confirm the predicted link between separations and training. Instead, the evidence supports alternative theories suggesting a direct link between profit sharing and training. Our results suggest that profit sharing changes employer-worker relations in a way that leads to greater formal and informal investment in worker skills but that this is independent of its influence on reducing separations.

Are flexible contracts bad for workers? Evidence from job satisfaction data

If workers can choose between permanent and flexible contracts, compensating wage differentials should arise to equalize on-the-job utility in the two types of contracts. Estimating job satisfaction using the British Household Panel Survey shows that agency and casual contracts are associated with routinely lower satisfaction. This results because the low job satisfaction associated with less job security is not offset by higher compensation or other job characteristics. Job security is sufficiently important that holding constant this one facet of satisfaction eliminates the overall gap in job satisfaction between flexible and permanent contracts.

Unions, Dissatisfied Workers and Sorting

A persistent and sizeable literature argues that the reported job dissatisfaction of union members is spurious. It reflects either the sorting of workers across union status or the sorting of union recognition across jobs. We cast doubt on this argument presenting the first estimates that use panel data to hold constant both worker and job match fixed effects. The estimates demonstrate that covered union members report greater dissatisfaction even when accounting for sorting in both dimensions. Moreover, covered union members are less likely to quit holding job satisfaction constant and their quit behaviour is far less responsive to job satisfaction. The paradox of the discontented union member remains intact.

Employed and unemployed job search methods: Australian evidence on search duration, wages and job stability

This paper examines the use and impact of job search methods of both unemployed and employed job seekers. Informal job search methods are associated with relativel high level of job exit and shorter search duration. Job exists through the public employment agency (PEA) display positive duration dependence for the unemployed. This may suggest that the PEA is used as a job search method of last resort. Informal job search methods have lower associated duration in search and higher wages than the PEA or answering advertisements. However, informal job search methods are aossociated with a higher turnover level

Worker absence and shirking: evidence from matched teacher-school data

We utilise a unique matched teacher-school data set of absenteeism records to quantify shirking behaviour in primary and secondary schools. Shirking behaviour is shown to vary systematically across schools, and hence schools are characterised as either healthy (low absenteeism) or sick (high absenteeism). Using count data techniques, and allowing for the problems of unobserved heterogeneity and partial observability in our data, we find that teachers in sick schools have higher absence rates. Our estimates suggest that shirking behaviour can account for 24 percent to 38 percent of recorded absenteeism. Furthermore, a teacher who moves from a healthy school to a sick school is likely to face an increased risk of absenteeism of up to 70 percent. As the factors a¤ecting involuntary absenteeism are unlikely to change in the short run, we argue that this increased incidence in absenteeism re?ects the impact of the change in school environment on shirking behaviour.

Worker absence and shirking : evidence from matched teacher-school data.

We utilise a unique matched teacher-school data set of absenteeism records to quantify the impact of group interaction on the absence behavior of primary and secondary teachers. To address problems of identification our study focuses on teachers who move between schools. The estimates for movers suggest that absenteeism is influenced by prevailing group absence behaviour at the school. Our finding suggests that a worker takes one more day of absenteeism if their average coworker takes 12 more days or 8 more days absenteeism per quarter for primary school and secondary school teachers, respectively. We interpret this as evidence that worker shirking is influenced by workplace absence norms

A Guideline for Increasing Efficiency of TEM/EDS Data Collection by Dwell Time Optimization

Composition analysis using energy dispersive spectroscopy (EDS) mapping in transmission electron microscopy (TEM) is crucial in the semiconductor industry for development of new products and enhancement of production yields. High quality EDS data relies on acquiring sufficient X-ray counts from the TEM sample. The amount of time that the electron beam interacts with the sample generating X-rays per pixel within the mapping area is known as dwell time, which is an EDS system parameter that governs optimum data acquisition. However, a systematic study to optimize this parameter has not been previously reported. An analytical expression was derived that enabled the prediction of a dwell time range that optimizes the total X-ray signal collected during the EDS data collection. Experimental results from multiple materials across several TEM/EDS systems confirmed the validity of the expression. The results of this study provide a guideline for increasing efficiency of TEM/EDS data collection from different materials using a variety of TEM/EDS systems through the optimization of EDS dwell time

In addition to saved travel time, the London congestion charge has saved lives

What was the effect of the London congestion charge on traffic accidents injuries and fatalities? Research by Colin Green finds that the introduction of the London congestion charge reduced the count of traffic accidents in Central London by 30 a month – an enormous 40 per cent reduction. Accidents that result in individuals being killed or seriously injured (KSIs) also fell, by just under 4 a month, or 45 a year
