A tax is a mandatory financial charge or some other type of levy imposed on a taxpayer by a governmental organization to collectively support 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 relief. The first known taxation took place in Ancient Egypt around 3000–2800 BC. Taxes consist of direct or indirect taxes and may be paid in money or as its labor equivalent.
William Spencer Vickrey was a Canadian-American professor of economics and Nobel Laureate. He was a lifelong faculty member at Columbia University. A theorist who worked on public economics and mechanism design, Vickrey primarily discussed public policy problems. He originated the Vickrey auction, introduced the concept of congestion pricing in networks, formalized arguments for marginal cost pricing, and contributed to optimal income taxation. James Tobin described him as "an applied economist’s theorist, as well as a theorist’s applied economist.”
Public choice, or public choice theory, is "the use of economic tools to deal with traditional problems of political science." It includes the study of political behavior. In political science, it is the subset of positive political theory that studies self-interested agents and their interactions, which can be represented in a number of ways—using standard constrained utility maximization, game theory, or decision theory. It is the origin and intellectual foundation of contemporary work in political economy.
James McGill Buchanan Jr. was an American economist known for his work on public choice theory originally outlined in his most famous work, The Calculus of Consent, co-authored with Gordon Tullock in 1962. He continued to develop the theory, eventually receiving the Nobel Memorial Prize in Economic Sciences in 1986. Buchanan's work initiated research on how politicians' and bureaucrats' self-interest, utility maximization, and other non-wealth-maximizing considerations affect their decision-making. He was a member of the Board of Advisors of The Independent Institute as well as of the Institute of Economic Affairs, a member of the Mont Pelerin Society (MPS) and MPS president from 1984 to 1986, a Distinguished Senior Fellow of the Cato Institute, and professor at George Mason University.
In economics, a public good is a good that is both non-excludable and non-rivalrous. Use by one person neither prevents access by other people, nor does it reduce availability to others. Therefore, the good can be used simultaneously by more than one person. This is in contrast to a common good, such as wild fish stocks in the ocean, which is non-excludable but rivalrous to a certain degree. If too many fish were harvested, the stocks would deplete, limiting the access of fish for others. A public good must be valuable to more than one user, otherwise, its simultaneous availability to more than one person would be economically irrelevant.
Public finance is the study of the role of the government in the economy. It is the branch of economics that assesses the government revenue and government expenditure of the public authorities and the adjustment of one or the other to achieve desirable effects and avoid undesirable ones. The purview of public finance is considered to be threefold, consisting of governmental effects on:
- The efficient allocation of available resources;
- The distribution of income among citizens; and
- The stability of the economy.
A 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.
Erik Lindahl was a Swedish economist. He was professor of economics at Uppsala University 1942–58 and in 1956–59 he was the President of the International Economic Association. He was an also an advisor to the Swedish government and the central bank, and in 1943 was elected as a member of the Royal Swedish Academy of Sciences. Lindahl posed the question of financing public goods in accordance with individual benefits. The quantity of the public good satisfies the requirement that the aggregate marginal benefit equals the marginal cost of providing the good.
Johan Gustaf Knut Wicksell was a Swedish economist of the Stockholm school. He was professor at Uppsala University and Lund University.
Although the actual definitions vary between jurisdictions, in general, a direct 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 taxes 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 except in the United States of America, where the term has special constitutional significance because of two provisions in the U.S. Constitution that any direct taxes imposed by the national government be apportioned among the states on the basis of population; and in the European Union, where direct taxation remains the sole responsibility of member states.
Equity, or economic equality, is the construct, concept or idea of fairness in economics and justice in the distribution of wealth, resources, and taxation within a society. Equity is closely tied to taxation policies, welfare economics, and the discussions of public finance, influencing how resources are allocated among different segments of the population.
A Lindahl tax is a form of taxation conceived by Erik Lindahl in which individuals pay for public goods according to their marginal benefits. In other words, they pay according to the amount of satisfaction or utility they derive from the consumption of an additional unit of the public good. Lindahl taxation is designed to maximize efficiency for each individual and provide the optimal level of a public good.
A government budget is a projection of the government's revenues and expenditure for a particular period, often referred to as a financial or fiscal year, which may or may not correspond with the calendar year. Government revenues mostly include taxes while expenditures consist of government spending. A government budget is prepared by the Central government or other political entity. In most parliamentary systems, the budget is presented to the legislature and often requires approval of the legislature. The government implements economic policy through this budget and realizes its program priorities. Once the budget is approved, the use of funds from individual chapters is in the hands of government ministries and other institutions. Revenues of the state budget consist mainly of taxes, customs duties, fees, and other revenues. State budget expenditures cover the activities of the state, which are either given by law or the constitution. The budget in itself does not appropriate funds for government programs, hence the need for additional legislative measures. The word budget comes from the Old French brunette.
Tax policy refers to the guidelines and principles established by a government for the imposition and collection of taxes. It encompasses both microeconomic and macroeconomic aspects, with the former focusing on issues of fairness and efficiency in tax collection, and the latter focusing on the overall quantity of taxes to be collected and its impact on economic activity. The tax framework of a country is considered a crucial instrument for influencing the country's economy.
In public finance, a sub-discipline of economics, fiscal incidence is the combined overall economic impact of both government taxation and expenditures on the real economic income of individuals.
Optimal 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. However, most taxes distort individual behavior, because the activity that is taxed becomes relatively less desirable; for instance, taxes on labour income reduce the incentive to work. The optimization problem involves minimizing the distortions caused by taxation, while achieving desired levels of redistribution and revenue. Some taxes are thought to be less distorting, such as lump-sum taxes and Pigouvian taxes, where the market consumption of a good is inefficient, and a tax brings consumption closer to the efficient level.
Public economics(or economics of the public sector) is the study of government policy through the lens of economic efficiency and equity. Public economics builds on the theory of welfare economics and is ultimately used as a tool to improve social welfare. Welfare can be defined in terms of well-being, prosperity, and overall state of being.
The hypothecation of a tax is the dedication of the revenue from a specific tax for a particular expenditure purpose. This approach differs from the classical method according to which all government spending is done from a consolidated fund.
Several theories of taxation exist in public economics. Governments at all levels need to raise revenue from a variety of sources to finance public-sector expenditures.
In public choice theory, tax choice is an emerging type of citizen sourcing in which individuals or groups of taxpayers decide how to allocate part of their taxes of a municipal or public budget appropriation through a process of democratic deliberation and decision-making. Its proponents apply the theory of consumer choice to public finance. They claim taxpayers react positively when they are allowed to allocate portions of their taxes to specific spending.
