Market (economics) in the context of "Social justice"

In microeconomics, economic efficiency, depending on the context, is usually one of the following two related concepts:

• Allocative or Pareto efficiency: any changes made to assist one person would harm another.
• Productive efficiency: no additional output of one good can be obtained without decreasing the output of another good, and production proceeds at the lowest possible average total cost.

These definitions are not equivalent: a market or other economic system may be allocatively but not productively efficient, or productively but not allocatively efficient. There are also other definitions and measures. All characterizations of economic efficiency are encompassed by the more general engineering concept that a system is efficient or optimal when it maximizes desired outputs (such as utility) given available inputs.

Market value or OMV (open market valuation) is the price at which an asset would trade in a competitive auction setting. Market value is often used interchangeably with open market value, fair value or fair market value, although these terms have distinct definitions in different standards, and differ in some circumstances.

Economics (/ˌɛkəˈnɒmɪks, ˌiːkə-/) is a social science that studies the production, distribution, and consumption of goods and services.

Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyses what is viewed as basic elements within economies, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and investment expenditure interact; and the factors of production affecting them, such as: labour, capital, land, and enterprise, inflation, economic growth, and public policies that impact these elements. It also seeks to analyse and describe the global economy.

Trade involves the transfer of goods and services from one person or entity to another, often in exchange for money. Economists refer to a system or network that allows trade as a market.

Traders generally negotiate through a medium of credit or exchange, such as money. Though some economists characterize barter (i.e. trading things without the use of money) as an early form of trade, money was invented before written history began. Consequently, any story of how money first developed is mostly based on conjecture and logical inference. Letters of credit, paper money, and non-physical money have greatly simplified and promoted trade as buying can be separated from selling, or earning. Trade between two traders is called bilateral trade, while trade involving more than two traders is called multilateral trade.

Innovation is the practical implementation of ideas that result in the introduction of new goods or services or improvement in offering goods or services. ISO TC 279 in the standard ISO 56000:2020 defines innovation as "a new or changed entity, realizing or redistributing value". Others have different definitions; a common element in the definitions is a focus on newness, improvement, and spread of ideas or technologies.

Innovation often takes place through the development of more-effective products, processes, services, technologies, art worksor business models that innovators make available to markets, governments and society.

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.

Capitalism is an economic system based on the private ownership of the means of production and their use for the purpose of obtaining profit. This socioeconomic system has developed historically through several stages and is defined by a number of basic constituent elements: private property, profit motive, capital accumulation, competitive markets, commodification, wage labor, and an emphasis on innovation and economic growth. Capitalist economies tend to experience business cycles of economic growth followed by recessions.

Economists, historians, political economists, and sociologists have adopted different perspectives in their analyses of capitalism and have recognized various forms of it in practice. These include laissez-faire or free-market capitalism, state capitalism, and welfare capitalism. Different forms of capitalism feature varying degrees of free markets, public ownership, obstacles to free competition, and state-sanctioned social policies. The degree of competition in markets and the role of intervention and regulation, as well as the scope of state ownership, vary across different models of capitalism. The extent to which different markets are free and the rules defining private property are matters of politics and policy. Most of the existing capitalist economies are mixed economies that combine elements of free markets with state intervention and in some cases economic planning.

A natural monopoly is a monopoly in an industry in which high infrastructure costs and other barriers to entry relative to the size of the market give the largest supplier in an industry, often the first supplier in a market, an overwhelming advantage over potential competitors. Specifically, an industry is a natural monopoly if a single firm can supply the entire market at a lower long-run average cost than if multiple firms were to operate within it. In that case, it is very probable that a company (monopoly) or a minimal number of companies (oligopoly) will form, providing all or most of the relevant products and/or services. This frequently occurs in industries where capital costs predominate, creating large economies of scale in relation to the size of the market; examples include public utilities such as water services, electricity, telecommunications, mail, etc. Natural monopolies were recognized as potential sources of market failure as early as the 19th century; John Stuart Mill advocated government regulation to make them serve the public good.

In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of cost (production cost). A decrease in cost per unit of output enables an increase in scale that is, increased production with lowered cost. At the basis of economies of scale, there may be technical, statistical, organizational or related factors to the degree of market control.

Economies of scale arise in a variety of organizational and business situations and at various levels, such as a production, plant or an entire enterprise. When average costs start falling as output increases, then economies of scale occur. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis. The economic concept dates back to Adam Smith and the idea of obtaining larger production returns through the use of division of labor. Diseconomies of scale are the opposite.
