This paper studies implicit pricing of non-wage job characteristics in the labour market using a two-sided matching model. It departs from the previous literature by allowing worker heterogeneity in productivity, which gives rise to a double transaction problem in a hedonic model. Deriving sufficient conditions under which assortative matching is the unique stable job-worker matching, we show t...

We interpret workers’ confidence in their own skills as their morale, and investigate the implication of worker overconfidence on the firm’s optimal wage-setting policies. In our model, wage contracts both provide incentives and affect worker morale, by revealing private information of the firm about worker skills. We provide conditions for the non-differentiation wage policy to be profit-maxim...

In "Altruism and the Origin of the Worker Caste," Bert Hölldobler and Edward Osborne Wilson explore the evolutionary origins of worker ants. "Altruism and the Origin of the Worker Caste" is the fourth chapter of Hölldobler and Wilson's book, The Ants, which was published by The Belknap Press of Harvard University [4] in Cambridge, Massachusetts, in 1990. In "Altruism and the Origin of the Worke...

BACKGROUND Health worker density per 1000 population in Ghana is one of the lowest in the world estimated to be 2.3, below the global average of 9.3. Low health worker motivation induced by poor working conditions partly explain this challenge. Albeit the wage bill for public sector health workers is about 90% of domestic government expenditure on health in countries such as Ghana, staff motiva...

healthy hire effect (hhe) is considered as an epidemiological phenomenon, complicating the assessment of a true cause - effect relationship between occupational exposure and health status of workers. the current study was aimed at identification and elimination of hhe in the risk assessment of arterial hypertension (ah) in coal miners. overall, 1553 miners, working in west siberia, were enrolle...

Worker policing, wherein social insect workers prevent their sisters from reproducing by eating worker-laid eggs, is recognized as a textbook example of kin selection in action. However, the evolutionary basis of policing was recently challenged in a study that suggested that police-workers remove worker-laid eggs not because rearing workers' sons reduces worker fitness, but merely because work...
