The Market for Lemons – Wikipedia

The Market for Lemons: As a consequence of the mechanism described in this paper, markets may fail to exist altogether in certain situations involving quality uncertainty.

In California and federal law, “Lemon Laws” cover anything mechanical. That is, if a customer in a fine establishment orders a lobster and the meat is not fresh, he can send the lobster back to the kitchen and refuse to pay for it. Low prices drive away sellers of high-quality goods, leaving only lemons behind. The buyer, however, takes this incentive into consideration, and takes the quality of the goods to be uncertain.

This is part of the basis for the idiom buyer beware. Quality Uncertainty markef the Market Mechanism”. This page was last edited on 6 Junemarkte Although Gresham’s principle applies more specifically to exchange rates, modified analogies can be drawn. But sellers know whether they hold a peach or a lemon. In American slang, a lemon is a car that is found to be defective only after it has been bought.

InAkerlof, along with Michael Spenceand Joseph Stiglitzjointly received the Nobel Memorial Prize in Economic Sciencesfor their research on issues related to asymmetric information. This, in turn, motivates the owners of moderately good cars not to sell, and so on. The defect must substantially hinder the vehicle’s use, value, or safety. This is likely the basis for the idiom that an informed consumer is a better consumer. The result is that a market in which there is asymmetric information with respect to quality shows characteristics similar to those described by Gresham’s Law: The cost of dishonesty, therefore, lies not only in the amount by which the purchaser is cheated; the cost also must include the loss incurred from driving legitimate business out of existence.


The withdrawal of good cars reduces the average quality of cars on the market, causing buyers to revise downward their expectations for any given car. Because many important mechanical parts and other elements are hidden from view and not easily accessible for inspection, the buyer of a car does not know beforehand whether it is a peach or a lemon. In this model, as quality is indistinguishable beforehand akdrlof the buyer due to the asymmetry of informationincentives exist for the seller to pass off low-quality goods as higher-quality ones.

The Market for Lemons

Akerlof’s paper shows how prices can determine the akerlot of goods traded on the market. The Economics of Price Discrimination. Therefore, owners of good cars will not place their cars on the used car market. There are also state laws regarding “lemons” which vary by state and may not necessarily cover used or leased vehicles.

So there will always be a distinct advantage for some vendors to offer low-quality goods to the less-informed segment of a market that, on the whole, appears to be of reasonable quality and have reasonable guarantees of certainty.

Purchasers who knowingly purchase a marrket in “as is” lemln accept the defects and void their rights under the “lemon law”. Hoffer and Michael D. Then they are only willing to pay a fixed price for a car that averages the value of a “peach” and “lemon” together p avg. Quality Uncertainty and the Market Mechanism ” is a well-known [1] paper by economist George Akerlof which examines how the quality of goods traded in a market can degrade in the presence of information asymmetry between buyers and sellers, leaving only “lemons” behind.

Eventually, as enough sellers of “peaches” leave the market, the average willingness-to-pay of buyers will decrease since the average quality of cars on the market decreasedleading to even more sellers of high-quality cars to leave the market through a positive feedback loop. However, not all players in a given market will follow the same rules ldmon have the same aptitude of karket quality.


This means that the owner of a carefully maintained, never-abused, good used car will be unable to get a high enough price to make selling that car worthwhile.

Only the average quality of the goods will be considered, which in turn will have the side effect that goods that are above average in terms of quality will be driven out of the market. There are good used cars “peaches” and defective used cars “lemons”normally as a consequence of several not-always-traceable variables, such as the owner’s driving style, quality and frequency of maintenance, and accident history.

Quarterly Journal of Economics. However, a definition of ‘highest quality’ for food eludes providers. The paper by Akerlof describes how the interaction between quality heterogeneity and asymmetric information can lead to the disappearance of a market where guarantees are indefinite.

The market for used cars collapses when there is asymmetric information. Anderson, oppose the regulatory approach proposed by the authors of the paper, observing that some used-car markets haven’t broken down even without lemon legislation and that the lemon problem creates entrepreneurial opportunities for alternative marketplaces or customers’ knowledgeable friends.

Retrieved from ” https: This mechanism is repeated until a no-trade equilibrium is reached. An example of this might be the subjective quality of fine food and wine. Thus, a large variety of better-quality and higher-priced restaurants are supported.

Suppose buyers cannot distinguish between a high-quality car a “peach” and a “lemon”.

Examples given aerlof Akerlof’s paper include the market for used cars, the dearth of formal credit markets in developing countries, and the difficulties that the elderly encounter in buying health insurance. Adverse selection is a market mechanism that can lead to a market collapse.

These state laws provide remedies to consumers for automobiles that repeatedly fail to meet certain standards of quality and performance. Market demand is given by:.
