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”. 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.

This mechanism is repeated until a no-trade equilibrium is reached. The buyer, however, takes this incentive into consideration, and takes the quality of the goods to be uncertain. As a consequence of the mechanism described in this paper, markets may fail to exist altogether in certain situations involving quality uncertainty. Journal of Consumer Policy. Low prices drive away sellers of high-quality goods, leaving only lemons behind.

The Market for Lemons – Wikipedia

Thus, a large variety of better-quality and higher-priced restaurants are supported. But sellers know whether they markef a peach or a lemon. Views Lemin Edit View history. 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.

Akerllf 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.


Akerlof’s paper uses the market for used cars as an example of the problem of quality uncertainty. The Market for Lemons: 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.

Libertarianslike William L. 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.

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. Market demand is given by:. This page was last edited on 6 Juneat Individual consumers know best what they prefer to eat, and quality is almost always assessed in fine establishments by smell and taste before they pay. Although Gresham’s principle applies more specifically to exchange rates, modified analogies can be drawn.

This is likely the basis for the idiom that an informed consumer is a better consumer. If a car has to be repaired for the same defect four or more times and the problem is still occurring, the car may be deemed to be “a lemon”. Examples given in 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. 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.

This is part of the basis for the idiom buyer beware. In California and federal law, “Lemon Laws” cover anything mechanical. The rights afforded to consumers by “lemon laws” may exceed the warranties expressed in purchase contracts.

From Wikipedia, the free encyclopedia. However, not all players in a given market will follow the same rules or have the same aptitude of assessing quality.

The market for used cars collapses when there is asymmetric information. 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.


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. Therefore, owners of good cars will not place their cars on the used car market. Retrieved from ” https: 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.

Purchasers who knowingly purchase a car in “as is” condition accept the defects and void their rights under the “lemon law”.

The defect must substantially hinder the vehicle’s use, value, or safety. Quarterly Journal of Economics.

The federal “lemon law” also provides that the warrantor may be obligated to pay the attorney fees of the party prevailng in a lemon law suit, as do most state lemon laws. Thus the uninformed buyer’s price creates an adverse selection problem that drives the high-quality cars from the market. markdt

The Market for Lemons

Rejected Classic Articles by Leading Economists”. This, in turn, motivates the owners of moderately good cars not to sell, and so on. 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. Akerlof’s paper shows how prices can determine the quality of goods traded on the market. Both the American Economic Review and the Review of Economic Studies rejected the paper for “triviality”, while the reviewers for Journal of Political Economy rejected it as incorrect, arguing that, if this paper were correct, then no goods could be traded.

An example of this might be the subjective quality of fine food and wine.
