OBJECTIVES High microbial exposures in farmers and agricultural workers are associated with less atopy. Although it has been speculated that healthy worker survival could be an explanation, this has not been studied so far. Therefore, we investigated the presence of healthy worker survival in a five-year follow-up study of an occupational cohort of Dutch farmers and agricultural industry (compa...

OBJECTIVES To assess the potential of a healthy worker survivor effect due to differential occupational mobility in a cohort of construction workers. METHODS A cohort of 10 809 male employees in the German construction industry aged 15-64 years was followed up for occupational mobility, early retirement due to permanent disability, and total mortality from 1986 to 1994. Using the Cox's propor...

This paper identifies and analyses a new effect related to the cyclical behaviour of labour supply: Entitled-Worker Effect (EWE). is different from well-known Added-Worker (AWE) Discouraged-Worker (DWE). The EWE consequence one most important institutions: unemployment benefit (UB). We develop model with uncertainty about results job-seeking transaction costs linked such search process, showing...

In their recent paper Portengen and colleagues have made an important contribution to our understanding of laboratory animal allergy. However, they have omitted to draw attention to an observation of clinical importance to occupational physicians. They have suggested that the lack of decline in lung function in ‘‘experienced’’ workers may be due to the healthy worker effect. Their suggestion is...

The strong logicodeductive method of science is applied in an investigation of the mortality of a large population of communications workers (338 306 white men) to explain the mortality deficits so often observed in occupational studies. A theory for the healthy worker effect is proposed, and its predictions are tested in comparisons of mortality curves fitted to Weibull functions using regress...
