Economics

The economy is: The production, exchange and consumption of socially valued items, both concrete and conceptual. And the social incentives and disincentives that govern these exchanges. This includes but is not limited to; currency, tangible items, services, food, water, housing, ideas, healthcare, real property, stocks, leases, promises of future services, favors, etc.

Next a list of things that might motivate an individual to participate in this exchange:

Basic survival need, perceived social need, pursuit of material reward, fear of punishment, pursuit of non-material reward, religious beliefs, pursuit of friendships or sexual partners.    

Next a list of the four basic economic systems.

1. Traditional Economic System.

2. The Command Economic System.

3. The Market Economic System.

4. The Mixed Economic System.

Market Economy:

From: Market Economy Wikipedia

1. Laissez-faire

Laissez-faire is synonymous with what was referred to as strict capitalist free market economy during the early and mid-19th century as a classical liberal (right-libertarian) ideal to achieve. It is generally understood that the necessary components for the functioning of an idealized free market include the complete absence of government regulation, subsidies, artificial price pressures, and government-granted monopolies (usually classified as coercive monopoly by free market advocates) and no taxes or tariffs other than what is necessary for the government to provide protection from coercion and theft, maintaining peace and property rights, and providing for basic public goods. Right-libertarian advocates of anarcho-capitalism see the state as morally illegitimate and economically unnecessary and destructive.

2. Free-Market Economy

Free-market economy refers to an economic system where prices for goods and services are set freely by the forces of supply and demand and are allowed to reach their point of equilibrium without intervention by government policy. It typically entails support for highly competitive markets, private ownership of productive enterprises. Laissez-faire is a more extensive form of free-market economy where the role of the state is limited to protecting property rights.

3. Welfare Capitalism

Welfare capitalism refers to a capitalist economy that includes public policies favoring extensive provisions for social welfare services. The economic mechanism involves a free market and the predominance of privately owned enterprises in the economy, but public provision of universal welfare services aimed at enhancing individual autonomy and maximizing equality. Examples of contemporary welfare capitalism include the Nordic model of capitalism predominant in Northern Europe

4. Anglo-Saxon model

Anglo-Saxon capitalism refers to the form of capitalism predominant in Anglophone countries and typified by the economy of the United States. It is contrasted with European models of capitalism such as the continental Social market model and the Nordic model. Anglo-Saxon capitalism refers to a macroeconomic policy regime and capital market structure common to the Anglophone economies. Among these characteristics are low rates of taxation, more open financial markets, lower labor market protections, and a less generous welfare state eschewing collective bargaining schemes found in the continental and northern European models of capitalism.

5. East Asian model

The East Asian model of capitalism involves a strong role for state investment, and in some instances involves state-owned enterprises. The state takes an active role in promoting economic development through subsidies, the facilitation of "national champions", and an export-based model of growth. The actual practice of this model varies by country. This designation has been applied to the economies of Singapore, Japan, Taiwan, South Korea and the People's Republic of China.

6. Social Market Economy

This model was implemented by Alfred Müller-Armack and Ludwig Erhard after World War II in West Germany. The social market economic model (sometimes called "Rhine capitalism") is based upon the idea of realizing the benefits of a free market economy, especially economic performance and high supply of goods, while avoiding disadvantages such as market failure, destructive competition, concentration of economic power and the socially harmful effects of market processes. The aim of the social market economy is to realize greatest prosperity combined with best possible social security. One difference from the free market economy is that the state is not passive, but takes active regulatory measures. The social policy objectives include employment, housing and education policies, as well as a socio-politically motivated balancing of the distribution of income growth. Characteristics of social market economies are a strong competition policy and a contractionary monetary policy. The philosophical background is Neoliberalism or Ordoliberalism.

7. Public Ownership models

In the 1930s the economists Oskar Lange and Abba Lerner developed a model of socialism that posited that a public body (dubbed the "Central Planning Board") could set prices through a trial-and-error approach until they equaled the marginal cost of production in order to achieve perfect competition and pareto optimality. In this model of socialism, firms would be state-owned and managed by their employees, and the profits would be disbursed among the population in a social dividend. This model came to be referred to as "market socialism" because it involved the use of money, a price system, and simulated capital markets; all of which were absent from traditional of non-market socialism.

A more contemporary model of market socialism is that put forth by the American economist John Roemer, referred to as Economic democracy. In this model, social ownership is achieved through public ownership of equity in a market economy. A Bureau of Public Ownership (BPO) would own controlling shares in publicly listed firms, so that the profits generated would be used for public finance and the provision of a basic income.

8. Cooperative Socialism

Libertarian socialists and left-anarchists often promote a form of market socialism in which enterprises are owned and managed cooperatively by their workforce so that the profits directly remunerate the employee-owners. These cooperative enterprises would compete with each other in the same way private companies compete with each other in a capitalist market. The first major elaboration of this type of market socialism was made by Pierre Joseph Proudhon and was called "mutualism".

Self-managed market socialism was promoted in Yugoslavia by economists Branko Horvat and Jaroslav Vanek. In the self-managed model of socialism, firms would be directly owned by their employees and the management board would be elected by employees. These cooperative firms would compete with each other in a market for both capital goods and for selling consumer goods.

9. Socialist Market Economy

Following the 1978 reforms, the People's Republic of China developed what it calls a "socialist market economy", in which most of the economy is under state ownership, with the state enterprises organized as joint-stock companies with various government agencies owning controlling shares through a shareholder system. Prices are set by a largely free-price system and the state-owned enterprises are not subjected to micromanagement by a government planning agency. A similar system called "socialist-oriented market economy" has emerged in Vietnam following the Đổi Mới reforms in 1986. This system is frequently characterized as "state capitalism" instead of market socialism because there is no meaningful degree of employee self-management in firms, because the state enterprises retain their profits instead of distributing them to the workforce or government, and because many function as de facto private enterprises. The profits neither finance a social dividend to benefit the population at large, nor do they accrue to their employees.

In the People's Republic of China, this economic model is presented as a "preliminary stage of socialism" to explain the dominance of capitalistic management practices and forms of enterprise organization in both the state and non-state sectors.
