Employees are being given more and more decisions to make with regards to their pension and healthcare plans. Yet increasing research in the social sciences shows that the decisions 'real' people make are not those of the thoughtful and well-informed economic agent often portrayed in economic research, but are often based on flawed information and made without a full understanding of their financial implications. The contributors to Pension Design and Structure explore theassumptions behind commonly-held theories of retirement decision-making, and the consequences of the growing volume of research in behavioural finance and economics for the field of pension research. Contributors are drawn from a variety of disciplines, and include leading pensions experts.
