SustainabilitySustainability is a social goal for people to co-exist on Earth over a long time. Specific definitions of this term are disputed and have varied with literature, context, and time. Experts often describe sustainability as having three dimensions (or pillars): environmental, economic, and social, and many publications emphasize the environmental dimension. In everyday use, sustainability often focuses on countering major environmental problems, including climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution.
InnovationInnovation 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.
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.
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.
TransportTransport (in British English) or transportation (in American English) is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipelines, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations.
