Abstract
Esping-Andersen's The Three Worlds of Welfare Capitalism has been very influential in comparative social policy because he develops a power analysis of welfare state formation. However, the analysis of political power that underpins his thesis has been widely misunder stood. In particular, the concept of welfare regime has lots its original conceptual meaning as a system of power stratification that upholds different types of welfare state. Instead it is widely misused merely to refer to particular types of welfare system.
