What is "welfarism"

n. (context rare derisive English) The belief in or support of the welfare state.

Welfarism is a form of consequentialism. Like all forms of consequentialism, welfarism is based on the premise that actions, policies, and/or rules should be evaluated on the basis of their consequences. Welfarism is the view that the morally significant consequences are impacts on human (or animal) welfare. There are many different understandings of human welfare, but the term "welfarism" is usually associated with the economic conception of welfare. Economists usually think of individual welfare in terms of utility functions, a perspective in which social welfare can be conceived as an aggregation of individual utilities or utility functions.

Welfarist views have been especially influential in the law and economics movement. Steven Shavell and Louis Kaplow have argued in an influential book, Fairness versus Welfare that welfare should be the exclusive criteria by which legal analysts evaluate legal policy choices.
