Sammanfattning	Welfare regime analysis classifies welfare states not by how much they spend but by the qualitative logic of how they distribute welfare, following Gosta Esping-Andersen's 1990 The Three Worlds of Welfare Capitalism. Its two organizing concepts are decommodification — the degree to which people can sustain a livelihood independent of the market — and stratification — the patterns of social inequality that welfare arrangements reproduce or alter. On these dimensions Esping-Andersen identified three clustered regime types: the liberal, the conservative-corporatist, and the social-democratic. His 1999 sequel extended the framework to the family and the postindustrial service economy, and a large critical literature has since debated additional types.	A corporatism index is a quantitative scaling of how centralized and coordinated a country's system of wage bargaining and interest intermediation is. Where the conceptual corporatism framework describes the institutional pattern in which peak associations of labor and capital negotiate with the state, a corporatism index turns that pattern into comparable numbers. The two landmark efforts are Alan Siaroff's 1999 integrated scale for 24 industrial democracies and Lane Kenworthy's 2003 systematic review and reconstruction of the available indicators. Both combine measures such as bargaining centralization, wage-setting coordination, union and employer organizational concentration, and the degree of tripartite concertation into a composite score that ranks countries from pluralist and decentralized at the low end to strongly corporatist and coordinated at the high end.
