Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced and rendered in a specific time period by a country or countries. GDP is often used to measure the economic health of a country or region. Several national and international economic organizations maintain definitions of GDP, such as the OECD and the International Monetary Fund.
In microeconomic theory, the opportunity cost of a choice is the value of the best alternative forgone where, given limited resources, a choice needs to be made between several mutually exclusive alternatives. Assuming the best choice is made, it is the "cost" incurred by not enjoying the benefit that would have been had if the second best available choice had been taken instead. The New Oxford American Dictionary defines it as "the loss of potential gain from other alternatives when one alternative is chosen". As a representation of the relationship between scarcity and choice, the objective of opportunity cost is to ensure efficient use of scarce resources. It incorporates all associated costs of a decision, both explicit and implicit. Thus, opportunity costs are not restricted to monetary or financial costs: the real cost of output forgone, lost time, pleasure, or any other benefit that provides utility should also be considered an opportunity cost.
In economics, the fiscal multiplier is the ratio of change in national income arising from a change in government spending. More generally, the exogenous spending multiplier is the ratio of change in national income arising from any autonomous change in spending. When this multiplier exceeds one, the enhanced effect on national income may be called the multiplier effect. The mechanism that can give rise to a multiplier effect is that an initial incremental amount of spending can lead to increased income and hence increased consumption spending, increasing income further and hence further increasing consumption, etc., resulting in an overall increase in national income greater than the initial incremental amount of spending. In other words, an initial change in aggregate demand may cause a change in aggregate output that is a multiple of the initial change.
The Bureau of Economic Analysis (BEA) of the United States Department of Commerce is a U.S. government agency that provides official macroeconomic and industry statistics, most notably reports about the gross domestic product (GDP) of the United States and its jurisdictions. They also provide information about personal income, corporate profits, and government spending in their National Income and Product Accounts (NIPAs).
Cost–benefit analysis (CBA), sometimes also called benefit–cost analysis, is a systematic approach to estimating the strengths and weaknesses of alternatives. It is used to determine options which provide the best approach to achieving benefits while preserving savings in, for example, transactions, activities, and functional business requirements. A CBA may be used to compare completed or potential courses of action, and to estimate or evaluate the value against the cost of a decision, project, or policy. It is commonly used to evaluate business or policy decisions, commercial transactions, and project investments. For example, the U.S. Securities and Exchange Commission must conduct cost-benefit analyses before instituting regulations or deregulations.
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. The most common example is the (aggregate) labour productivity measure, one example of which is GDP per worker. There are many different definitions of productivity and the choice among them depends on the purpose of the productivity measurement and data availability. The key source of difference between various productivity measures is also usually related to how the outputs and the inputs are aggregated to obtain such a ratio-type measure of productivity.
Managerial economics is a branch of economics involving the application of economic methods in the organizational decision-making process. Economics is the study of the production, distribution, and consumption of goods and services. Managerial economics involves the use of economic theories and principles to make decisions regarding the allocation of scarce resources. It guides managers in making decisions relating to the company's customers, competitors, suppliers, and internal operations.
In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies. Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.
In energy conservation and energy economics, the rebound effect is the reduction in expected gains from new technologies that increase the efficiency of resource use, because of behavioral or other systemic responses. These responses diminish the beneficial effects of the new technology or other measures taken. A definition of the rebound effect is provided by Thiesen et al. (2008) as, “the rebound effect deals with the fact that improvements in efficiency often lead to cost reductions that provide the possibility to buy more of the improved product or other products or services.” A classic example from this perspective is a driver who substitutes a vehicle with a fuel-efficient version, only to reap the benefits of its lower operating expenses to commute longer and more frequently."
Economics of corruption deals with the misuse of public power for private benefit and its economic impact on society. This discipline aims to study the causes and consequences of corruption and how it affects the economic functioning of the state.
In economics, a spillover is a positive or a negative, but more often negative, impact experienced in one region or across the world due to an independent event occurring from an unrelated environment.
HIV/AIDS affects economic growth by reducing the availability of human capital. Without proper prevention, nutrition, health care and medicine that is available in developing countries, large numbers of people are developing AIDS.
Transportation Economic Development Impact System (TREDIS) is an economic analysis system sold by consulting firm Economic Development Research Group that is used in planning major transportation investments in the US and Canada. The role of economic impact analysis and TREDIS in the transportation planning process is explained in guidebooks of the US Department of Transportation and American Association of State Highway and Transportation Officials.
Economics of participation is an umbrella term spanning the economic analysis of worker cooperatives, labor-managed firms, profit sharing, gain sharing, employee ownership, employee stock ownership plans, works councils, codetermination, and other mechanisms which employees use to participate in their firm's decision making and financial results.
The Regional Input–Output Modeling System is a regional economic model developed and maintained by the US Bureau of Economic Analysis (BEA).
Infrastructure-based economic development, also called infrastructure-driven development, combines key policy characteristics inherited from the Rooseveltian progressive tradition and neo-Keynesian economics in the United States, France's Gaullist and neo-Colbertist indicative planning, Scandinavian social democracy as well as Singaporean and Chinese state capitalism: it holds that a substantial proportion of a nation’s resources must be systematically directed towards long term assets such as transportation, energy and social infrastructure in the name of long term economic efficiency and social equity.
Farmers' markets are markets in which producers sell directly to consumers. While farmers' markets do not have a measurable impact on the United States economy as a whole, many studies have found that farmers' markets impact state and municipal economies as well as vendors, local businesses, and consumers. These impacts are measured using the IMPLAN Input-Output Model and the Sticky Economic Evaluation Device (SEED), in addition to other methods. The economic impacts that are most frequently measured include effects on the revenue and income of local growers and local businesses, the effects on job creation, and the effects on other sectors of state and local economies. Some obstacles that may reduce impact or create negative economic effects include over-saturation, socioeconomic barriers, the opportunity cost of farmers' markets, and the projected unsustainable growth of farmers' markets in the United States.
In business economics cost breakdown analysis is a method of cost analysis, which itemizes the cost of a certain product or service into its various components, the so-called cost drivers. The cost breakdown analysis is a popular cost reduction strategy and a viable opportunity for businesses.
This glossary of economics is a list of definitions containing terms and concepts used in economics, its sub-disciplines, and related fields.
In addition to the direct reduction in travel times the HSR project will produce, there are also economic and environmental impacts of the high-speed rail system. These were also specifically noted in Proposition 1A at the time the project sought authorization from the voters of the state in 2008. The anticipated benefits apply both generally to the state overall, as well as to the regions the train will pass through, and to the areas immediately around the train stations.
