Erik Lindahl
Erik Lindahl (21 November 1891 – 6 January 1960) 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. Lindahl's contributions to economic theory extend beyond his Wicksellian roots to embrace much of what is contained in modern Neo- Walrasian theory. Lindahl's formulation of the concept of sequence economies and intertemporal equilibrium (1929, 1930) is by far the first rigorous attempt to do so. Lindahl's couching of a theory of capital (1929, 1939) in intertemporal terms anticipat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Frank Hahn
Frank Horace Hahn FBA (26 April 1925 – 29 January 2013) was a British economist whose work focused on general equilibrium theory, monetary theory, Keynesian economics and critique of monetarism. A famous problem of economic theory, the conditions under which money, which is intrinsically worthless, can have a positive value in a general equilibrium, is called " Hahn's problem" after him. One of Hahn's main abiding concerns was the understanding of Keynesian (Non-Walrasian) outcomes in general equilibrium situations. Biography Early life and education Frank Hahn was born on 26 April 1925 in Berlin to Arnold and Maria Hahn, their roots in German and Czech speaking Jewish communities respectively. Arnold Hahn was a chemist by profession and a writer. Arnold and Maria Hahn with their two sons, Peter and Frank, moved to Prague in 1931 (or possibly 1934) and left for England in 1938. Frank's older brother was Peter Hahn (8 November 1923 – 28 August 2007) who became an eminent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pareto Efficient
In welfare economics, a Pareto improvement formalizes the idea of an outcome being "better in every possible way". A change is called a Pareto improvement if it leaves at least one person in society better off without leaving anyone else worse off than they were before. A situation is called Pareto efficient or Pareto optimal if all possible Pareto improvements have already been made; in other words, there are no longer any ways left to make one person better off without making some other person worse-off. In social choice theory, the same concept is sometimes called the unanimity principle, which says that if ''everyone'' in a society ( non-strictly) prefers A to B, society as a whole also non-strictly prefers A to B. The Pareto front consists of all Pareto-efficient situations. In addition to the context of efficiency in ''allocation'', the concept of Pareto efficiency also arises in the context of ''efficiency in production'' vs. '' x-inefficiency'': a set of outputs of go ...

Samuelson Condition
The Samuelson condition, due to Paul Samuelson, in the theory of public economics, is a condition for optimal provision of public goods. For an economy with ''n'' consumers, the conditions is: : \sum_^n \text_i = \text MRS''i'' is individual ''i'' marginal rate of substitution and MRT is the economy's marginal rate of transformation between the public good and an arbitrarily chosen private good. Note that while the marginal rates of substitution are indexed by individuals, the marginal rate of transformation is not; it is an economy wide rate. If the private good is a numeraire good then the Samuelson condition can be re-written as: : \sum_^n \text_i = \text where \text_i is the marginal benefit to each person of consuming one more unit of the public good, and \text is the marginal cost of providing that good. In other words, the public good should be provided as long as the overall benefits to consumers from that good are at least as great as the cost of providing it ...

Equilibrium (economics)
In economics, economic equilibrium is a situation in which the economic forces of supply and demand are balanced, meaning that economic variables will no longer change. 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. This price is often called the competitive price or market clearing price and will tend not to change unless demand or supply changes, and quantity is called the "competitive quantity" or market clearing quantity. Understanding economic equilibrium An economic equilibrium is a situation when the economic agent cannot change the situation by adopting any strategy. The concept has been borrowed from the physical sciences. Take a system where physical forces are balanced for instance.This economically interpreted means no further change ensues.

International Economic Review
The ''International Economic Review'' (IER) is a quarterly peer-reviewed scientific journal in economics published by the Economics Department of the University of Pennsylvania and Osaka University. The journal's focus is wide and includes many areas of economics, including econometrics, economic theory, macroeconomics, and applied economics. IER was started in 1960 by Michio Morishima, at Osaka University's Institute of Social Economic Research (ISER), and Lawrence R. Klein, at the University of Pennsylvania's Wharton School and Department of Economics. The Kansai Economic Federation of Osaka materially and financially supported the IER at its initial stages. In the present, the IER is run as a non-profit joint academic venture between ISER and the Department of Economics at the University of Pennsylvania. The journal is currently edited by Harold L. Cole of the Pennsylvania Editorial Office and co-edited by Charles Yuji Horioka of the Osaka Editorial Office. The chair o ...

Leif Johansen
Leif Johansen (11 May 1930 – 29 December 1982) was a Norwegian economist who made a substantial contribution to economic science. He was born in Eidsvoll. Throughout his academic career Johansen was employed at the University of Oslo. He was a member of the Norwegian Academy of Science and Letters. Johansen was a lifelong communist, a central board member of the Communist Party of Norway The Communist Party of Norway (, NKP) is a communist party in Norway. The NKP was formed in 1923, following a split in the Norwegian Labour Party.

Willingness To Pay
In behavioral economics, willingness to pay (WTP) is the maximum price at or below which a consumer will definitely buy one unit of a product. This corresponds to the standard economic view of a consumer reservation price. Some researchers, however, conceptualize WTP as a range. According to the constructed preference view, consumer willingness to pay is a context-sensitive construct; that is, a consumer's WTP for a product depends on the concrete decision context. For example, consumers tend to be willing to pay more for a soft drink in a luxury hotel resort in comparison to a beach bar or a local retail store. Experimental context In laboratory experiments auctions are conducted, a premise of the experiment is often that "bid = WTP".

Utility
In economics, utility is a measure of a certain person's satisfaction from a certain state of the world. Over time, the term has been used with at least two meanings. * In a normative context, utility refers to a goal or objective that we wish to maximize, i.e., an objective function. This kind of utility bears a closer resemblance to the original utilitarian concept, developed by moral philosophers such as Jeremy Bentham and John Stuart Mill. * In a descriptive context, the term refers to an ''apparent'' objective function; such a function is revealed by a person's behavior, and specifically by their preferences over lotteries, which can be any quantified choice. The relationship between these two kinds of utility functions has been a source of controversy among both economists and ethicists, with most maintaining that the two are distinct but generally related. Utility function Consider a set of alternatives among which a person has a preference ordering. A utility fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Public Good (economics)
In economics, a public good (also referred to as a social good or collective good)Oakland, W. H. (1987). Theory of public goods. In Handbook of public economics (Vol. 2, pp. 485–535). Elsevier. is a commodity, product or service that is both non-excludable and non-rivalrous and which is typically provided by a government and paid for through taxation. Use by one person neither prevents access by other people, nor does it reduce availability to others, so 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. Capital goods may be used to produce public goods or services that are "...ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Taxation
A tax is a mandatory financial charge or levy imposed on an individual or legal person, legal entity by a governmental organization to support government spending and public expenditures collectively or to Pigouvian tax, regulate and reduce negative Externality, externalities. Tax compliance refers to policy actions and individual behavior 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 occurred in Ancient Egypt around 3000–2800 BC. Taxes consist of direct tax, direct or indirect taxes and may be paid in money or as labor equivalent. All countries have a tax system in place to pay for public, common societal, or agreed national needs and for the functions of government. Some countries levy a flat tax, flat percentage rate of taxation on personal annual income, but most progressive tax, scale taxes are progressive based on brackets of yearly income amounts. Most ...
