Untitled[ edit ] I dont use Wikipedia a lot, but on the Kaldor-Hicks page it said Pareto efficiency is impossible in most case. From what i know most exchanges are pareto efficient. Regarding the previous paragraph:
The principle behind CB analysis is the Kaldor-Hicks Principlebut the core ideas figure prominently in much of conventional economics.
In contrast to this rather mainstream tradition, Hicks juxtaposed the tradition of the Lausanne School Walras and Pareto and the Austrian School of economics which focused on the mutually beneficial transactions of market exchanges. In more narrow terms, the contrast between the two traditions is embodied in the contrast between the aforementioned notion of Kaldor-Hicks efficiency and the notion of Pareto efficiency.

A change in the social state of affairs is a Pareto improvement if someone becomes better off in terms of their own welfare or utility and no one becomes worse off.
The criterion for a Pareto improvement is often criticized as being too stringent, so the notion of a Kaldor-Hicks improvement is intended as a more practical alternative. Given a possible change in the social state, monetize the gain of the people who become better off and monetize the losses of those who are made worse off, and then since the gains and losses are now in the same units, one can consider if the gains outweigh the losses to give a positive net benefit—a Kaldor-Hicks improvement.
The basic idea is that the monetized gain is the maximum amount of money the gainers would be willing to pay to have the change, and the monetized losses is the minimum amount of compensation the losers would have to receive so they would not be worse off by the Kaldor hicks criterion analysis.
The increase in social wealth is a change in the size of the pie while the redistribution is only a change in the slices of the pie not its total size. The question of the size of the social-wealth pie is a question of efficiency that is the professional concern of economists while the question of slices is a question of equity that is the concern of politicians, philosophers, poets, or the like.
Richard Posner, the main founder of the economic analysis of law, makes this point in the context of law and economics as well as cost-benefit analysis. But to the extent that distributive justice can be shown to be the proper business of some other branch of government or policy instrument…, it is possible to set distributive considerations to one side and use the Kaldor-Hicks approach with a good conscience.
This assumes, …, that efficiency in the Kaldor-Hicks sense—making the pie larger without worrying about how the relative size of the slices changes—is a social value. Legal, Economic, and Philosophical Perspectives. But the proponents of CB analysis including law and economics perfectly agree with this point as indicated by the Posner quote; they are only making recommendations from the viewpoint of efficiency.
One can redescribe exactly that same situation in such a way that the two parts reverse themselves.
What Economics has to do with Law and why it matters Mary has an apple which she values at fifty cents while John values an apple at one dollar. There might be a voluntary exchange where Mary sold the apple to John for, say, seventy-five cents.
There are two changes in that Pareto improvement: Let us apply social wealth maximization reasoning to the transfer of the apple using money as the numeraire or unit of account. Since the apple was worth fifty cents to Mary and a dollar to John, social wealth would be increased by fifty cents by the apple transfer from Mary to John.
That is an increase in efficiency. The other change, the transfer of seventy-five cents from John to Mary, is a question of distribution or equity. Social wealth measured in dollars and cents would be unchanged by the mere transfer of seventy-five cents from one person to another.
It would still be an improvement, and by the same amount, if John stole the apple—price zero—or if Mary lost it and John found it. Mary is fifty cents worse off, John is a dollar better off, net gain fifty cents. All of these represent the same efficient allocation of the apple: They differ in the associated distribution of income: The total amount of money never changes; we are simply shifting it from one person to another.
The total quantity of goods never changes either, since we are cutting off our analysis after John gets the apple but before he eats it. Yet total value increases by fifty cents. It increases because the same apple is worth more to John than to Mary.
Shifting money around does not change total value.
One dollar is worth the same number of dollars to everyone: Describe exactly the same situation but take apples as the numeraire or unit of account. For John the marginal rate of substitution of dollars for apples was one so John would value the loss of the three-quarters of a dollar at three-quarters of an apple.
The acquired apple would be worth one apple so the total change is worth one-quarter apple to John. Since the loss of her apple is worth one apple to her, she also has a positive net gain half an apple from the exchange. One apple is worth the same number of apples to everyone: Hence the whole attempt to take a shortcut around the Pareto principle using the Kaldor-Hicks parsing into efficiency plus equity parts of the total change apple plus money transfers breaks down.
A simple redescription of the same transfers with the other good as numeraire reverses the conclusions.efficiency criterions, Kaldor-Hicks Efficiency Criterion has received several positive and negative comments. A fundamental issue in economic analysis of law . If Kaldor-Hicks efficient means no more Kaldor-Hicks improvements are possible, then a Pareto efficient allocation is not necessarily Kaldor-Hicks efficient.
As I said, this is the reason for having the criterion in the first place. Kaldor Hicks Criteria, Net Benefit, Benefit-Cost Ratio, External Costs of Production, Impact of Policy, Negative Net Social Benefits, Value of Impact, Constant Marginal Cost are .
The Kaldor – Hicks Criterion. Postulations.
The compensation criterion of Kaldor – Hicks is based on the following: Each individual’s satisfactions are independent . In a separate essay published in the same year, John Hicks defends the same idea, and assessment of alternatives in terms of net benefits is often called “the Kaldor-Hicks efficiency criterion.”.
