First published in 1987. The reform of the welfare state in the United Kingdom is high on the agenda of all political parties and the proposals for reform, both official and private, are numerous. In this book, Professor Beenstock and his colleagues took a comprehensive account of the social security of the 1980s, as well as the tax system, as it had evolved over the Beveridge era and how it affected our incentive to work. The book describes the theory of labour supply decisions in their relationship to the tax benefit system. It illustrates how tax and social security arrangements affected labour supply decisions as well as monitoring how these decisions had evolved over the post-war period. It also considers retirement decisions in the UK as well as the government’s plans to reform the social security system.
