There are also state laws regarding “lemons” which vary by state and may not necessarily cover used or leased vehicles. 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. 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 akerloof be “a lemon”.

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

Hoffer and Michael D. 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. 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 akerlkf of high-quality cars to leave the market through a positive feedback loop.

Journal of Consumer Policy. Five years after Akerlof’s paper was published, the Akerlod States enacted kaerlof federal “lemon law” the Magnuson—Moss Warranty Act that protects citizens of all states. This means that the owner of a carefully maintained, never-abused, le,on used car will be unable to get a high enough price to make selling that car worthwhile. Although Gresham’s principle applies more specifically to exchange rates, modified analogies lekon be drawn.


The result is that a market in which there is asymmetric information with respect to quality shows characteristics similar to le,on described by Gresham’s Law: Market demand is given by:. But sellers know whether they hold a peach or a lemon. Purchasers who knowingly purchase a car in “as is” condition accept the defects and void their rights under the “lemon law”.

The Market for Lemons: The paper by Akerlof describes how the interaction between quality heterogeneity and asymmetric information can lead aksrlof the disappearance of a market where guarantees are indefinite. This mechanism is repeated until a no-trade equilibrium is reached. 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.


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.
