Social liberalismSocial liberalism (Sozialliberalismus, socioliberalismo, Sociaalliberalisme) is a political philosophy and variety of liberalism that endorses social justice and the expansion of civil and political rights. It is economically based on the social market economy and views the common good as harmonious with the individual's freedom. Social liberals overlap with social democrats in accepting economic intervention more than other liberals; its importance is considered auxiliary compared to social democrats.
Mutualism (economic theory)Mutualism is an anarchist school of thought and economic theory that advocates a socialist society based on free markets and usufructs, i.e. occupation and use property norms. One implementation of this system involves the establishment of a mutual-credit bank that would lend to producers at a minimal interest rate, just high enough to cover administration. Mutualism is based on a version of the labor theory of value that it uses as its basis for determining economic value.
Economic interventionismEconomic interventionism, sometimes also called state interventionism, is an economic policy position favouring government intervention in the market process with the intention of correcting market failures and promoting the general welfare of the people. An economic intervention is an action taken by a government or international institution in a market economy in an effort to impact the economy beyond the basic regulation of fraud, enforcement of contracts, and provision of public goods and services.
