How do workers fare in a continually changing labour market? This volume contains 15 papers, each examining how socio-economic changes affect worker wellbeing. Among the findings are: most increases in female labour force participation occur among women with high husbands' earnings, dispelling the myth that shrinking husbands' relative earnings cause women's work activities to rise; increased globalization equalizes pay between but expands pay within corporate establishments; high quality colleges widen the earnings distribution for top earners but only negligibly affect earnings for low wage earners; mathematical success depends on school quality more so than verbal learning; adult daughters who visit ailing parents daily in a nursing home decrease their annual labour supply by about 1000 hours, implying a welfare loss of $180,000; physical and/or sexual abuse appear to afflict over 30 per cent of the population leading to a 15 per cent drop in employment probability and a 32 per cent loss in wages; and training workers in an entirely new occupation raises an employee's wage growth while training workers in the same occupation decreases their wage growth, at least during the Russian economy's recent transition.
