"We provide a comprehensive focussed discussion of the long-term evolution of time budgets in a range of European, North-American and Pacific democracies, summarising arguments about the changing balances between work and leisure as well as paid and unpaid work. We contrast economists' assumptions about the purely instrumental nature of work, with sociological and social-psychological arguments as to why we might want or need work in and for itself."
