	Lonergan Institute IDEA
		For instance, in the first chapter, Lonergan employs two examples from physics (Newton and Einstein on the unintelligibility of constant velocity), and two examples from mathematics (the square root of two and non-countable multitudes) to explain the nature of inverse insight.
		First, economic ends meeting material needs for a society must be clearly distinguished from other kinds and types of ends.
		In a commonwealth, the "weal or welfare of all persons" is the deciding factor and operative goal for all the decisions which are made.

	Pareto efficiency - Wikipedia, the free encyclopedia
		In particular, it can be shown that, under certain idealised conditions, a system of free markets will lead to a Pareto efficient outcome.
		This was first demonstrated mathematically by economists Kenneth Arrow and Gerard Debreu, although the result may not necessarily reflect the workings of real economies because of the restrictive assumptions necessary for the proof (markets exist for all possible goods, markets are perfectly competitive, and transaction costs are negligible).
		For example with a dictatorship, both with dictator Alice or with dictator Bob, the outcome will be Pareto efficient because in the first instance it will be impossible to raise the well-being of anyone without reducing Alice's benefit and similarly for Bob.

	APPROPRIATION AND EFFICIENCY: A REVISION OF THE FIRST THEOREM OF WELFARE ECONOMICS Magazine: American Economic Review, ... (Site not responding. Last check: 2007-11-01)
		First, it is proved that rewarding individuals with their social marginal products (full appropriation) is good for incentives: it leads to efficient occupational choices, excepting perhaps for some coordination problems.
		First and most obvious, the theorem is only a "partial" optimality result in that it does not claim that v is globally Pareto efficient.
		A Revision of the First Theorem Our main result says that, provided everyone is rewarded with his or her social marginal product, such superadditivity is the only possible source of inefficiency.

	A Quiet Revolution In Welfare Economics
		After all, a reasonable reaction to the implication of Theorem 6.2 that matches between supplies and desires are not necessarily deserving of praise is that partial equilibrium conclusions are frequently not sustained by general equilibrium analysis.
		Theorem 6.2 certainly points out the necessity of extending the insights of human capital theory to preference development and falsifies the usual "separability" assumption necessary to justify partial equilibrium applications of neoclassical welfare theory.
		First, we must define the concept "degree of nonoptimality." Beyond judging situations to be Pareto optimal or non-Pareto optimal, we wish to judge whether situations are closer or farther from a particular Pareto optimum.

	The First Annual Feasta Lecture, by Herman Daly
		The first is the upper line, economic services, which are wants being served by what I've called manmade capital, the brown stuff in the economy, artefacts.
		Let's design an index which is a measure of welfare or which we think is a measure of welfare and then we'll correlate GNP with our attempt to measure welfare." They called their index Measured Economic Welfare, MEW and they discovered that, yes indeed, low and behold, there was a positive correlation.
		The conclusion they reached was that even though GNP was never intended as a measure of welfare, nevertheless it was sufficiently well correlated with welfare such that we could continue to operate on the assumption that it was a reasonable measure of welfare.

		Use the Lyapunov convexity theorem to show that the aggregate net preferred set is convex and the core property of the given allocation to show that the aggregate net preferred set is disjoint from an appropriate cone.
		For finite economies, the second welfare theorem depends on convexity of preferences; because the indivisibility of club memberships introduces an essential non-convexity in our context, it should come as no surprise that the second welfare theorem may fail for finite club economies.
		The first is that we require endowments to be bounded; no such assumption is required in the familiar exchange case.

	Solutions to Sample Questions 3
		The Second Welfare Theorem states that every Pareto efficient allocation can be sustained as a competitive equilibrium, given appropriate lump sum redistribution and sufficient convexity.
		The First Welfare Theorem states that every competitive equilibrium is Pareto-efficient.
		The Second Welfare Theorem gives conditions under which a given Pareto-efficient allocation can be decentralized – that is, provided using the price mechanism by the private market, featuring optimizing individuals who take prices as given.

	The Paretian System: IV - Social Welfare
		The First Fundamental Theorem of welfare economics claims that competitive equilibria are Pareto-optimal.
		The Second Welfare Theorem was, of course, at the heart of the argument of Enrico Barone (1908) and Vilfredo Pareto (1896; 1906: p.266-9) on the efficiency of a "socialist planning" which opened up the famous "Socialist Calculation debate".
		The Paretian welfare theorems, which rest comfortably on ordinal utility, was deemed the only acceptable criterion.

	The Paretian System: II - Efficiency
		The Fundamental Theorems of Welfare Economics are deservingly famous as they link the concept of a competitive equilibrium with that of a Pareto-optimal allocation.
		The First and Second Welfare Theorems were proved graphically by Abba Lerner (1934) and mathematically by Harold Hotelling (1938), Oskar Lange (1942) and Maurice Allais (1943: p.617-35) (see also Abba Lerner (1944) and Paul Samuelson (1947)).
		Graphically, the basic idea of the First Theorem is simple: as we saw in our discussion of equilibrium in the Paretian system, if we have a competitive equilibrium, all three of the Pareto-optimal conditions are met.

	Open-Ended Dynamic Economies (Leigh Tesfatsion)
		The standard First Welfare Theorem found in most economic theory textbooks establishes under weak regularity conditions that all competitive equilibria are Pareto efficient for a particular class of economic models, namely, the standard Walrasian general equilibrium model.
		In each case we show that a First Welfare Theorem is restored for the OG model if trade intermediation is modeled as a contestable activity carried out by a profit-seeking corporate intermediary (a Walrasian Auctioneer in a corporate business suit) operating on behalf of its consumer-shareholders.
		This study argues that the failure of the First Welfare Theorem, and the potentially exotic nature of the resulting business cycle fluctuations that arise, can both be attributed to the passive intermediation role played by the Walrasian Auctioneer in these models.

		The first fundamental theorem of welfare economics is often misunderstood, especially by technical economists.
		The First Fundamental Theorem of Welfare Economics is proof, in view of its long list of prerequisites, that market outcome can be improved by well-designed interventions.
		Posted by: Eric H at Aug 13, 2007 10:48:32 PM Alex, in logic and mathematics, it's common for a major theorem (and it seems like anything called "the first fundamental theorem of..." counts as major) to be subjected to repeated attempts to weaken the assumptions necessary to prove the theorem.

		There are two theorems that enable us to connect the efficiency conditions with market institutions.
		First Welfare Theorem – When a competitive equilibrium exists it is Pareto efficient (Pareto optimal).
		Second Welfare Theorem – A Pareto optimum can be achieved through a competitive equilibrium from a suitable redistribution of initial endowments.

		Pareto efficiency is incomplete as a welfare notion in that it has nothing to say about equity.
		R = G + a S, where R measures overall government utility, G is the private payoff to the government, S represents the welfare of the general public, and a is a parameter measuring how much weight the government attaches to the general public’s interests.
		A competitive equilibrium in the pure exchange economy is a set of prices and an allocation of goods to consumers such that all markets clear at those prices and all consumers maximize utility subject to their budget constraint, taking prices as given.

	What is Austrian Economics
		And they lived up to Ludwig von Mises's rule: the first job of an economist is to tell governments what they cannot do.
		He realized that economics is not about the amassing of data, but rather about the verbal elucidation of universal facts (for example, wants are unlimited, means are scarce) and their logical implications.
		Together with the contemporaneous writings of Leon Walras and Stanley Jevons, Menger spelled out the subjective basis of economic value, and fully explained, for the first time, the theory of marginal utility (the greater the number of units of a good that an individual possesses, the less he will value any given unit).

		Adam Smith, that is. Having just completed writing a history of economics,1 I have concluded that, despite the protestations of Murray Rothbard and other detractors, the eighteenth-century moral philosopher and celebrated author of The Wealth of Nations deserves to be named the founding father of modern economics.
		The reason: Adam Smith is the first major figure to articulate in a profound way what has become known as the first fundamental theorem of welfare economics: that the invisible hand of competition automatically transforms self-interest into the common good.
		In short, Smith's thesis is that a "system of natural liberty," an economic system that allows individuals to pursue their own self-interest under conditions of competition and common law, would be a self-regulating and highly prosperous economy.
