In health economic evaluation studies, to value productivity loss due to absenteeism, existing methods use wages as a proxy value for marginal productivity. This study is the first to test the equality between wage and marginal productivity losses due to absenteeism separately for team workers and non-team workers. Our estimates are based on linked employer-employee data from Canada. Results in...

Schedule delays commonly occur in construction projects and often result in delay and low productivity. Several studies have proposed different schedule delay analysis methodologies. By using asplanned and as-built schedules most studies have concentrated on calculating and identifying the delay events on project but have neglected the low productivity. Loss in productivity, which is a primary ...

OBJECTIVE Growing evidence demonstrates a relationship between excess health risk and preventable productivity loss. There is a need to quantify how much lost productivity is avoidable through employer-sponsored health management interventions. This study introduced the Normal Impairment Factor (NIF) to recognize the amount of productivity loss that cannot be mitigated through health management...

Objectives: To determine and compare the impact of rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriasis on work productivity, to calculate the productivity costs (PC), and to map out factors that influence (functional status and disease activity) work productivity. Methods: The Work Productivity and Activity Impairment questionnaire was used to evaluate productivity losses of p...

PURPOSE The aim of this study was to assess whether organizational justice lowers productivity loss and sickness absence, and whether there are reverse effects of productivity loss and sickness absence on organizational justice. METHOD A longitudinal study with 2 years of follow-up was conducted among employed persons aged 45-64 years from the Study on Transitions in Employment, Ability and M...

This study at a major financial services corporation sought to investigate the association of arthritis with on-the-job productivity, also termed "presenteeism." Using a modified version of the Work Limitations Questionnaire (WLQ) incorporated into a Health Risk Appraisal (HRA), 17,685 employees responded to the survey in 2002. Of the 16,651 respondents meeting inclusion criteria, 2,469 (14.8%)...

BACKGROUND AND AIMS Evidence on indirect cost of Crohn's disease (CD) is available but typically provides information on the loss of productivity at paid work of patients. In the present study, the quality of life and indirect costs of CD patients were assessed (overall and by disease severity). METHODS A self-report questionnaire-based study among adult Polish patients with CD was performed....

The loss of biodiversity is threatening ecosystem productivity and services worldwide, spurring efforts to quantify its effects on the functioning of natural ecosystems. Previous research has focused on the positive role of biodiversity on resource acquisition (i.e., niche complementarity), but a lack of study on resource utilization efficiency, a link between resource and productivity, has ren...
