This title was first published in 2000:  This volume is based on papers presented at the sixth International Research Seminar on "Issues in Social Security", held by FISS on 12-15 June 1999 in Sigtuna, Sweden. The book relates to the discussion about the merits of improving the incentive structure of social security programmes by privatization. The first part contains two important chapters - the first looks at the interaction between programmes and how they make one of them to serve the purposes of the other. This mechanism is termed "domain linkage". The second chapter deals with welfare state programmes that contain behavioural risks, like health insurance, sickness benefits, unemployment and disability insurance - where moral hazard is a potential problem. The second part of the book groups a number of international comparative studies. The first three deal with retirement issues, and the fourth looks at the development of poverty and income distribution.
