Three-sector modelThe three-sector model in economics divides economies into three sectors of activity: extraction of raw materials (primary), manufacturing (secondary), and service industries which exist to facilitate the transport, distribution and sale of goods produced in the secondary sector (tertiary). The model was developed by Allan Fisher, Colin Clark, and Jean Fourastié in the first half of the 20th century, and is a representation of an industrial economy. It has been criticised as inappropriate as a representation of the economy in the 21st century.
Information economyInformation economy is an economy with an increased emphasis on informational activities and information industry, where information is valued as a capital good. The term was coined by Marc Porat, a graduate student at Stanford University, who would later co-found General Magic. Manuel Castells states that information economy is not mutually exclusive with manufacturing economy. He finds that some countries such as Germany and Japan exhibit the informatization of manufacturing processes.
Post-industrial societyIn sociology, the post-industrial society is the stage of society's development when the service sector generates more wealth than the manufacturing sector of the economy. The term was originated by Alain Touraine and is closely related to similar sociological theoretical concepts such as post-Fordism, information society, knowledge economy, post-industrial economy, liquid modernity, and network society. They all can be used in economics or social science disciplines as a general theoretical backdrop in research design.
Public choicePublic choice, or public choice theory, is "the use of economic tools to deal with traditional problems of political science". Its content includes the study of political behavior. In political science, it is the subset of positive political theory that studies self-interested agents (voters, politicians, bureaucrats) and their interactions, which can be represented in a number of ways – using (for example) standard constrained utility maximization, game theory, or decision theory.
EconomicsEconomics (ˌɛkəˈnɒmᵻks,_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 analyzes what's viewed as basic elements in the economy, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers.
Industry (economics)In macroeconomics, an industry is a branch of an economy that produces a closely related set of raw materials, goods, or services. For example, one might refer to the wood industry or to the insurance industry. When evaluating a single group or company, its dominant source of revenue is typically used by industry classifications to classify it within a specific industry. For example the International Standard Industrial Classification (ISIC) – used directly or through derived classifications for the official statistics of most countries worldwide – classifies "statistical units" by the "economic activity in which they mainly engage".
Information revolutionThe term information revolution describes the "radical changes wrought by computer technology on the storage of and access to information since the mid-1980s" or current economic, social and technological trends beyond the Industrial Revolution. Many competing terms have been proposed that focus on different aspects of this societal development. The British polymath crystallographer J. D. Bernal introduced the term "scientific and technical revolution" in his 1939 book The Social Function of Science to describe the new role that science and technology are coming to play within society.
DirigismeDirigisme or dirigism () is an economic doctrine in which the state plays a strong directive (policies) role, contrary to a merely regulatory interventionist role, over a market economy. As an economic doctrine, dirigisme is the opposite of laissez-faire, stressing a positive role for state intervention in curbing productive inefficiencies and market failures. Dirigiste policies often include indicative planning, state-directed investment, and the use of market instruments (taxes and subsidies) to incentivize market entities to fulfill state economic objectives.
InfrastructureInfrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access).
Production–possibility frontierIn microeconomics, a production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB) is a graphical representation showing all the possible options of output for two goods that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time. A PPF illustrates several economic concepts, such as allocative efficiency, economies of scale, opportunity cost (or marginal rate of transformation), productive efficiency, and scarcity of resources (the fundamental economic problem that all societies face).
