This, in turn, motivates the owners of moderately good cars not to sell, and so on. From Wikipedia, the free encyclopedia. Five years after Akerlof’s paper was published, the United States enacted a federal “lemon law” the Magnuson—Moss Warranty Act that protects citizens of all states.

The withdrawal of good cars reduces the average quality of cars wkerlof the market, causing buyers to revise downward their expectations for any given car. 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.

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.

This mechanism is repeated until a no-trade equilibrium is reached. Akerlof’s paper uses the market for used cars as an example of the problem of quality uncertainty. This page was last edited on 6 Juneat 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.

A used car is one jarket which ownership is transferred from one person to another, after a period of use by its first owner and its inevitable wear and tear. However, a definition of ‘highest quality’ for food eludes providers. This is part of the basis for the idiom buyer beware.

InAkerlof, along with Michael Spenceand Joseph Stiglitzjointly received the Nobel Memorial Prize in Economic Sciencesfor their research on issues related to asymmetric information. Market demand is given by:.

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. This is likely the basis for the idiom that an informed consumer is a better consumer.

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. Libertarianslike William L. The Economics akrelof Price Discrimination. Thus, a large variety of better-quality and higher-priced restaurants are supported.

In this model, as quality lemob indistinguishable beforehand by the buyer due to the asymmetry of informationincentives exist for the seller to pass off low-quality goods as higher-quality ones. Journal of Consumer Policy. 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. As a consequence of the mechanism described in this paper, markets may fail to exist altogether in certain situations involving quality uncertainty.

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. 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.

These state laws provide remedies to consumers for automobiles that repeatedly fail to meet certain standards of quality and performance. Journal of Economic Perspectives. Thus the uninformed buyer’s price creates an adverse selection problem that drives the high-quality cars from the market.


The Market for Lemons: 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 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.

Akerlof’s paper shows how prices can determine the quality of goods traded on the market. But sellers know whether they hold a peach or a lemon.

The buyer, however, takes this incentive into consideration, and takes the quality of the goods to be uncertain. 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: Therefore, owners of good cars will not place their cars on the used car market.

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. In California and federal law, “Lemon Laws” cover anything mechanical. There are also state laws regarding “lemons” which vary by state and may aketlof necessarily cover used or leased vehicles.

In American slang, a lemon is a car that is kaerlof to be defective only after it has been msrket. 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.
