Economic ideology in the context of "Normative economics"

Socialism is an economic and political philosophy encompassing diverse economic and social systems characterised by social ownership of the means of production, as opposed to private ownership. It describes the economic, political, and social theories and movements associated with the implementation of such systems. Social ownership can take various forms, including public, community, collective, cooperative, or employee. As one of the main ideologies on the political spectrum, socialism is the standard left-wing ideology in most countries. Types of socialism vary based on the role of markets and planning in resource allocation, and the structure of management in organizations.

Socialist systems are divided into non-market and market forms. A non-market socialist system seeks to eliminate the perceived inefficiencies, irrationalities, unpredictability, and crises that socialists traditionally associate with capital accumulation and the profit system. Market socialism retains the use of monetary prices, factor markets and sometimes the profit motive. As a political force, socialist parties and ideas exercise varying degrees of power and influence, heading national governments in several countries. Socialist politics have been internationalist and nationalist; organised through political parties and opposed to party politics; at times overlapping with trade unions and other times independent and critical of them, and present in industrialised and developing nations. Social democracy originated within the socialist movement, supporting economic and social interventions to promote social justice. While retaining socialism as a long-term goal, in the post-war period social democracy embraced a mixed economy based on Keynesianism within a predominantly developed capitalist market economy and liberal democratic polity that expands state intervention to include income redistribution, regulation, and a welfare state.

Neoliberalism is a political and economic ideology that advocates for free-market capitalism, which became dominant in policy-making from the late 20th century onward. The term has multiple, competing definitions, and is most often used pejoratively. In scholarly use, the term is often left undefined or used to describe a multitude of phenomena. However, it is primarily employed to delineate the societal transformation resulting from market-based reforms.

Neoliberalism is often associated with a set of economic liberalization policies, including privatization, deregulation, depoliticisation, consumer choice, labor market flexibilization, economic globalization, free trade, monetarism, austerity, and reductions in government spending. These policies are designed to increase the role of the private sector in the economy and society. Additionally, the neoliberal project is oriented towards the establishment of institutions and is inherently political in nature, extending beyond mere economic considerations.

Communism (from Latin communis 'common, universal') is a political and economic ideology whose goal is the creation of a communist society, a socioeconomic order centered on common ownership of the means of production, distribution, and exchange that allocates products in society based on need. A communist society entails the absence of private property and social classes, and ultimately money and the state. Communism is a part of the broader socialist movement.

Communists often seek a voluntary state of self-governance but disagree on the means to this end. This reflects a distinction between a libertarian socialist approach of communization, revolutionary spontaneity, and workers' self-management, and an authoritarian socialist, vanguardist, or party-driven approach to establish a socialist state, which is expected to wither away. Communist parties have been described as radical left or far-left.

Economic liberalism is a political and economic ideology that supports a market economy based on individualism and private property in the means of production. Adam Smith is considered one of the primary initial writers on economic liberalism, and his writing is generally regarded as representing the economic expression of 19th-century liberalism up until the Great Depression and rise of Keynesianism in the 20th century. Historically, economic liberalism arose in response to feudalism and mercantilism.

Economic liberalism is associated with markets and private ownership of capital assets. Economic liberals tend to oppose government intervention and protectionism in the market economy when it inhibits free trade and competition, but tend to support government intervention where it protects property rights, opens new markets or funds market growth, and resolves market failures. They also tend to oppose cartels, monopolies, financialization of the economy, rent-seeking behaviour and unproductive classes reliant on rent, assets or state-granted privileges. An economy that is managed according to these precepts may be described as a liberal economy or operating under liberal capitalism. Economic liberals commonly adhere to a political and economic philosophy that advocates a restrained fiscal policy and a balanced budget through measures such as low taxes, reduced government spending, and minimized government debt. Free trade, deregulation, tax cuts, privatization, labour market flexibility, and opposition to trade unions are also common positions.

Democratic socialism is a left-wing economic and political philosophy that supports political democracy and some form of a socially owned economy, with a particular emphasis on economic democracy, workplace democracy, and workers' self-management within a market socialist, decentralised planned, or democratic centrally planned socialist economy. Democratic socialists argue that capitalism is inherently incompatible with the values of freedom, equality, and solidarity and that these ideals can only be achieved through the realisation of a socialist society. Although most democratic socialists seek a gradual transition to socialism, democratic socialism can support revolutionary or reformist politics to establish socialism. Democratic socialism was popularised by socialists who opposed the backsliding towards a one-party state in the Soviet Union and other countries during the 20th century. In Scandinavian countries as well as others, people often use "social democracy" and "democratic socialism" interchangeably to describe leftist movements aiming for gradual, democratic reform.

The history of democratic socialism can be traced back to 19th-century socialist thinkers across Europe and the Chartist movement in Britain, which somewhat differed in their goals but shared a common demand for democratic decision-making and public ownership of the means of production and viewed these as fundamental characteristics of the society they advocated for. From the late 19th to the early 20th century, democratic socialism was heavily influenced by the gradualist form of socialism promoted by the British Fabian Society and Eduard Bernstein's evolutionary socialism in Germany.
