Optimal Tax
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 (where individuals cannot change their behaviour to red ...

Social Welfare Function
In welfare economics, a social welfare function is a function that ranks social states (alternative complete descriptions of the society) as less desirable, more desirable, or indifferent for every possible pair of social states. Inputs of the function include any variables considered to affect the economic welfare of a society. In using welfare measures of persons in the society as inputs, the social welfare function is individualistic in form. One use of a social welfare function is to represent prospective patterns of collective choice as to alternative social states. The social welfare function provides the government with a simple guideline for achieving the optimal distribution of income. The social welfare function is analogous to the consumer theory of indifference-curve–budget constraint tangency for an individual, except that the social welfare function is a mapping of individual preferences or judgments of everyone in the society as to collective choices, which ...

Horizontal Equity
Equity, or economic equality, is the concept or idea of fairness in economics, particularly in regard to taxation or welfare economics. More specifically, it may refer to a movement that strives to provide equal life chances regardless of identity, to provide all citizens with a basic and equal minimum of income, goods, and services or to increase funds and commitment for redistribution. Overview According to Peter Corning, there are three distinct categories of substantive fairness (equality, equity, and reciprocity) that must be combined and balanced in order to achieve a truly fair society. Inequality and inequities have significantly increased in recent decades. Equity is based on the idea of moral equality. Equity looks at the distribution of capital, goods, and access to services throughout an economy and is often measured using tools such as the Gini index. Equity may be distinguished from economic efficiency in overall evaluation of social welfare. Although 'equity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

OECD
The Organisation for Economic Co-operation and Development (OECD; french: Organisation de coopération et de développement économiques, ''OCDE'') is an intergovernmental organisation with 38 member countries, founded in 1961 to stimulate economic progress and world trade. It is a forum whose member countries describe themselves as committed to democracy and the market economy, providing a platform to compare policy experiences, seek answers to common problems, identify good practices, and coordinate domestic and international policies of its members. The majority of OECD members are high-income economies with a very high Human Development Index (HDI), and are regarded as developed countries. Their collective population is 1.38 billion. , the OECD member countries collectively comprised 62.2% of global nominal GDP (US$49.6 trillion) and 42.8% of global GDP ( Int$54.2 trillion) at purchasing power parity. The OECD is an official United Nations observer. In April 194 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat Tax
A flat tax (short for flat-rate tax) is a tax with a single rate on the taxable amount, after accounting for any deductions or exemptions from the tax base. It is not necessarily a fully proportional tax. Implementations are often progressive due to exemptions, or regressive in case of a maximum taxable amount. There are various tax systems that are labeled "flat tax" even though they are significantly different. The defining characteristic is the existence of only one tax rate other than zero, as opposed to multiple non-zero rates that vary depending on the amount subject to taxation. A flat tax system is usually discussed in the context of an income tax, where progressivity is common, but it may also apply to taxes on consumption, property or transfers. Unlike progressive taxes, which include complex and numerous exceptions left to the tax collectors’ discretion, the flat tax is clear cut. In combination with the low rate, its simplicity considerably reduces the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Price Elasticity Of Demand
A good's price elasticity of demand (E_d, PED) is a measure of how sensitive the quantity demanded is to its price. When the price rises, quantity demanded falls for almost any good, but it falls more for some than for others. The price elasticity gives the percentage change in quantity demanded when there is a one percent increase in price, holding everything else constant. If the elasticity is −2, that means a one percent price rise leads to a two percent decline in quantity demanded. Other elasticities measure how the quantity demanded changes with other variables (e.g. the income elasticity of demand for consumer income changes). Price elasticities are negative except in special cases. If a good is said to have an elasticity of 2, it almost always means that the good has an elasticity of −2 according to the formal definition. The phrase "more elastic" means that a good's elasticity has greater magnitude, ignoring the sign. Veblen and Giffen goods are two classes of goo ...

Price Elasticity Of Supply
The price elasticity of supply (PES or Es) is a measure used in economics to show the responsiveness, or elasticity, of the quantity supplied of a good or service to a change in its price. The elasticity is represented in numerical form, and is defined as the percentage change in the quantity supplied divided by the percentage change in price. When the elasticity is less than one, the supply of the good can be described as ''inelastic''; when it is greater than one, the supply can be described as ''elastic''.Png, Ivan (1999). pp. 129–32. An elasticity of zero indicates that quantity supplied does not respond to a price change: the good is "fixed" in supply. Such goods often have no labor component or are not produced, limiting the short run prospects of expansion. If the elasticity is exactly one, the good is said to be ''unit-elastic''. The quantity of goods supplied can, in the short term, be different from the amount produced, as manufacturers will have stocks which they ...
