Ad valorem tax

ad valoremad valorem'' taxad valorem property tax
If we consider, for instance, two normal goods, x and y, whose prices are respectively p x and p y and an individual budget constraint given by the equation xp x + yp y = Y, where Y is the income, the slope of the budget constraint, in a graph where is represented good x on the vertical axis and good y on the horizontal axes, is equal to -p y /p x . The initial equilibrium is in the point (C), in which budget constraint and indifference curve are tangent, introducing an ad valorem tax on the y good (budget constraint: p x x + p y (1 + τ)y = Y), the budget constraint's slope becomes equal to -p y (1 + τ)/p x . The new equilibrium is now in the tangent point (A) with a lower indifferent curve.
An ad valorem tax (Latin for "according to value") is a tax whose amount is based on the value of a transaction or of property.

A lump-sum tax is a special way of taxation, based on a fixed amount, rather than on the real circumstance of the taxed entity.


chartalistChartalistsModern Monetary Theory
According to the proponents of the chartalist theory of money creation, taxes are not needed for government revenue, as long as the government in question is able to issue fiat money.
In macroeconomics, chartalism is a theory of money which argues that money originated with states' attempts to direct economic activity rather than as a spontaneous solution to the problems with barter or as a means with which to tokenize debt, and that fiat currency has value in exchange because of sovereign power to levy taxes on economic activity payable in the currency they issue.

Value-added tax

Since governments also resolve commercial disputes, especially in countries with common law, similar arguments are sometimes used to justify a sales tax or value added tax.

In addition, taxes are applied to fund foreign aid and military ventures, to influence the macroeconomic performance of the economy (a government's strategy for doing this is called its fiscal policy; see also tax exemption), or to modify patterns of consumption or employment within an economy, by making some classes of transaction more or less attractive.
In economics and political science, fiscal policy is the use of government revenue collection (mainly taxes) and expenditure (spending) to influence the economy.


The most extreme anti-tax view, anarcho-capitalism, holds that all social services should be voluntarily bought by the person(s) using them.
In an anarcho-capitalist society, law enforcement, courts and all other security services would be operated by privately funded competitors selected by consumers rather than centrally through confiscatory taxation.
