General equilibrium theoryIn economics, general equilibrium theory attempts to explain the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that the interaction of demand and supply will result in an overall general equilibrium. General equilibrium theory contrasts with the theory of partial equilibrium, which analyzes a specific part of an economy while its other factors are held constant.
TaxA tax is a compulsory financial charge or some other type of levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to collectively fund government spending, public expenditures, or as a way to regulate and reduce negative externalities. Tax compliance refers to policy actions and individual behaviour aimed at ensuring that taxpayers are paying the right amount of tax at the right time and securing the correct tax allowances and tax reliefs.
Optimal taxOptimal tax theory or the theory of optimal taxation is the study of designing and implementing a tax that maximises a social welfare function subject to economic constraints. The social welfare function used is typically a function of individuals' utilities, most commonly some form of utilitarian function, so the tax system is chosen to maximise the aggregate of individual utilities. Tax revenue is required to fund the provision of public goods and other government services, as well as for redistribution from rich to poor individuals.
Free marketIn economics, a free market is an economic system in which the prices of goods and services are determined by supply and demand expressed by sellers and buyers. Such markets, as modeled, operate without the intervention of government or any other external authority. Proponents of the free market as a normative ideal contrast it with a regulated market, in which a government intervenes in supply and demand by means of various methods such as taxes or regulations.
Economic equilibriumIn economics, economic equilibrium is a situation in which economic forces such as supply and demand are balanced and in the absence of external influences the (equilibrium) values of economic variables will not change. For example, in the standard text perfect competition, equilibrium occurs at the point at which quantity demanded and quantity supplied are equal. Market equilibrium in this case is a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers.
Market socialismMarket socialism is a type of economic system involving social ownership of the means of production within the framework of a market economy. Various models for such a system exist, usually involving some mix of public, cooperative, and privately owned enterprises. The central idea is that, as in capitalism, businesses compete for profits, however they will be "owned, or at least governed," by those who work in them. Market socialism differs from non-market socialism in that the market mechanism is utilized for the allocation of capital goods and the means of production.
Tax rateIn a tax system, the tax rate is the ratio (usually expressed as a percentage) at which a business or person is taxed. There are several methods used to present a tax rate: statutory, average, marginal, and effective. These rates can also be presented using different definitions applied to a tax base: inclusive and exclusive. A statutory tax rate is the legally imposed rate. An income tax could have multiple statutory rates for different income levels, where a sales tax may have a flat statutory rate.
Market (economics)In economics, a market is a composition of systems, institutions, procedures, social relations or infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services (including labour power) to buyers in exchange for money. It can be said that a market is the process by which the prices of goods and services are established. Markets facilitate trade and enable the distribution and allocation of resources in a society.
Regressive taxA regressive tax is a tax imposed in such a manner that the tax rate decreases as the amount subject to taxation increases. "Regressive" describes a distribution effect on income or expenditure, referring to the way the rate progresses from high to low, so that the average tax rate exceeds the marginal tax rate. In terms of individual income and wealth, a regressive tax imposes a greater burden (relative to resources) on the poor than on the rich: there is an inverse relationship between the tax rate and the taxpayer's ability to pay, as measured by assets, consumption, or income.
Computable general equilibriumComputable general equilibrium (CGE) models are a class of economic models that use actual economic data to estimate how an economy might react to changes in policy, technology or other external factors. CGE models are also referred to as AGE (applied general equilibrium) models. A CGE model consists of equations describing model variables and a database (usually very detailed) consistent with these model equations. The equations tend to be neoclassical in spirit, often assuming cost-minimizing behaviour by producers, average-cost pricing, and household demands based on optimizing behaviour.
Dynamic stochastic general equilibriumDynamic stochastic general equilibrium modeling (abbreviated as DSGE, or DGE, or sometimes SDGE) is a macroeconomic method which is often employed by monetary and fiscal authorities for policy analysis, explaining historical time-series data, as well as future forecasting purposes. DSGE econometric modelling applies general equilibrium theory and microeconomic principles in a tractable manner to postulate economic phenomena, such as economic growth and business cycles, as well as policy effects and market shocks.
Free-market environmentalismFree-market environmentalism argues that the free market, property rights, and tort law provide the best means of preserving the environment, internalizing pollution costs, and conserving resources. Free-market environmentalists therefore argue that the best way to protect the environment is to clarify and protect property rights. This allows parties to negotiate improvements in environmental quality. It also allows them to use torts to stop environmental harm.
Tax lawTax law or revenue law is an area of legal study in which public or sanctioned authorities, such as federal, state and municipal governments (as in the case of the US) use a body of rules and procedures (laws) to assess and collect taxes in a legal context. The rates and merits of the various taxes, imposed by the authorities, are attained via the political process inherent in these bodies of power, and not directly attributable to the actual domain of tax law itself. Tax law is part of public law.
New Keynesian economicsNew Keynesian economics is a school of macroeconomics that strives to provide microeconomic foundations for Keynesian economics. It developed partly as a response to criticisms of Keynesian macroeconomics by adherents of new classical macroeconomics. Two main assumptions define the New Keynesian approach to macroeconomics. Like the New Classical approach, New Keynesian macroeconomic analysis usually assumes that households and firms have rational expectations.
Direct taxAlthough the actual definitions vary between jurisdictions, in general, a direct tax or income tax is a tax imposed upon a person or property as distinct from a tax imposed upon a transaction, which is described as an indirect tax. There is a distinction between direct and indirect tax depending on whether the tax payer is the actual taxpayer or if the amount of tax is supported by a third party, usually a client. The term may be used in economic and political analyses, but does not itself have any legal implications.
Land value taxA land value tax (LVT) is a levy on the value of land without regard to buildings, personal property and other improvements. It is also known as a location value tax, a point valuation tax, a site valuation tax, split rate tax, or a site-value rating. Land value taxes are generally favored by economists as they do not cause economic inefficiency, and reduce inequality. A land value tax is a progressive tax, in that the tax burden falls on land owners, because land ownership is correlated with wealth and income.
FairTaxFairTax is a single rate tax proposal which has been proposed as a bill in the United States Congress regularly since 2005 that includes complete dismantling of the Internal Revenue Service. The proposal would eliminate all federal income taxes (including the alternative minimum tax, corporate income taxes, and capital gains taxes), payroll taxes (including Social Security and Medicare taxes), gift taxes, and estate taxes, replacing them with a single consumption tax on retail sales.
New classical macroeconomicsNew classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical framework. Specifically, it emphasizes the importance of rigorous foundations based on microeconomics, especially rational expectations. New classical macroeconomics strives to provide neoclassical microeconomic foundations for macroeconomic analysis.
Poll taxA poll tax, also known as head tax or capitation, is a tax levied as a fixed sum on every liable individual (typically every adult), without reference to income or resources. Poll is an archaic term for "head" or "top of the head". The sense of "counting heads" is found in phrases like polling place and opinion poll. Head taxes were important sources of revenue for many governments from ancient times until the 19th century. In the United Kingdom, poll taxes were levied by the governments of John of Gaunt in the 14th century, Charles II in the 17th and Margaret Thatcher in the 20th century.
MacroeconomicsMacroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole—for example, using interest rates, taxes, and government spending to regulate an economy's growth and stability. This includes regional, national, and global economies. Macroeconomists study topics such as GDP (Gross Domestic Product), unemployment (including unemployment rates), national income, price indices, output, consumption, inflation, saving, investment, energy, international trade, and international finance.
