Keynesianism in the context of "Private sector"

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.

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.

The Chicago school of economics is a neoclassical school of economic thought associated with the work of the faculty at the University of Chicago, some of whom have constructed and popularized its principles. Milton Friedman and George Stigler are considered the leading scholars of the Chicago school.

Chicago macroeconomic theory rejected Keynesianism in favor of monetarism until the mid-1970s, when it turned to new classical macroeconomics heavily based on the concept of rational expectations. The freshwater–saltwater distinction is largely antiquated today, as the two traditions have heavily incorporated ideas from each other. Specifically, new Keynesian economics was developed as a response to new classical economics, electing to incorporate the insight of rational expectations without giving up the traditional Keynesian focus on imperfect competition and sticky wages.

Thatcherism is a form of British conservative ideology named after Conservative Party leader Margaret Thatcher that relates to not just her political platform and particular policies but also her personal character and style of management while in office. Proponents of Thatcherism are referred to as Thatcherites. The term has been used to describe the principles of the British government under Thatcher from the 1979 general election to her resignation in 1990. In international terms, Thatcherites have been described as a part of the general socio-economic movement known as neoliberalism, with different countries besides the United Kingdom (such as the United States) sharing similar policies around expansionary capitalism.

Thatcherism represents a systematic, decisive rejection and reversal of the post-war consensus inside Great Britain in terms of governance, whereby the major political parties largely agreed on the central themes of Keynesianism, the welfare state, nationalised industry, and close regulation of the British economy before Thatcher's rise to prominence. Under her administration, there was one major exception to Thatcherite changes: the National Health Service (NHS), which was widely popular with the British public. In 1982, Thatcher promised that the NHS was "safe in our hands".

In economics, the Pigou effect is the stimulation of output and employment caused by increasing consumption due to a rise in real balances of wealth, particularly during deflation. The term was named after Arthur Cecil Pigou by Don Patinkin in 1948.

Real wealth was defined by Arthur Cecil Pigou as the summation of the money supply and government bonds divided by the price level. He argued that Keynes' General Theory was deficient in not specifying a link from "real balances" to current consumption and that the inclusion of such a "wealth effect" would make the economy more "self correcting" to drops in aggregate demand than Keynes predicted. Because the effect derives from changes to the "Real Balance", this critique of Keynesianism is also called the Real Balance effect.
