To a backdrop of ageing societies, pension crises and labour market reforms, this book investigates how the policy shift from early retirement to active ageing has affected individual retirement behaviour. Focusing on eleven European countries, the United States and Japan, it brings together leading international experts to analyze recent changes in pension systems. Their findings demonstrate that there has been a fundamental transition in pension policies and a steep increase in older workers' retirement ages and employment rates. Yet changes in retirement behavior are not evenly distributed across all societal strata. This raises the serious concern that an overall rise in the retirement age will be accompanied by the re-emergence of social inequality in the transition from work to retirement. This innovative edited collection will appeal to students and scholars of sociology, economics, political science, human resources management, gerontology and social policy, and also to policy-makers and professionals dealing with older workers.
