== Concise description of theory ==<br />
In 1970 George Akerlof published a ground breaking paper about the consequences of information assymetry. The full title is : 'The Market for Lemons: Quality Uncertainty and the Market Mechanism'.<br />
<br />
In markets where it is impossible to asses the quality of a product/service, where, so to say the seller of the product has more information than the buyer, the market will gradualy deteriorate and maybe even eventually dissapear altogether. <br />
<br />
The main issue is that quality is unassesible beforehand, thus giving sellers incentives to present the product/service as being of higher quality than it actually is. The buyer, however, knows this and will take the average quality of the market into consideration. This will have as a result that high quality products/services will leave the market, since they will only sell for average market quality goods. <br />
<br />
Therefore the average market quality will deteriorate and the market will shrink.<br />
<br />
The paper also talks about the 'cost of dishonesty'.<br />
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.<br />
<br />
The name is derived from the main example Akerlof uses in his paper. He explains his theory with the used cars market, in which a bad car is called a 'lemon'.<br />

<br />
== Concise description of theory ==<br />
*In economics, more precisely in contract theory, '''signaling''' is the idea that one party (termed the ''agent'') credibly conveys some information about itself to another party (the ''principal''). For example, in Michael Spence's job-market signalling model, (potential) employees send a signal about their ability level to the employer by acquiring certain education credentials. The informational value of the credential comes from the fact that the employer assumes it is positively correlated with having greater ability.<br />
*In the IS literature, signaling theory has been used to study how IT artifacts and Non-IT mechanisms could mitigate consumers' uncertainty about sellers and products.<br />

*In economics, more precisely in contract theory, '''signaling''' is the idea that one party (termed the ''agent'') credibly conveys some information about itself to another party (the ''principal''). For example, in Michael Spence's job-market signalling model, (potential) employees send a signal about their ability level to the employer by acquiring certain education credentials. The informational value of the credential comes from the fact that the employer assumes it is positively correlated with having greater ability.<br />

Market deterioration in markets with information asymmetry <br />

- Price of product<br><br />
- Acclaimed product quality by selling party<br><br />
- Expected/perceived product quality by buying party<br><br />

- Average market price of the product<br />
== Concise description of theory ==<br />
In 1970 George Akerlof published a ground breaking paper about the consequences of information assymetry. The full title is : 'The Market for Lemons: Quality Uncertainty and the Market Mechanism'.<br />
<br />
In markets where it is impossible to asses the quality of a product/service, where, so to say the seller of the product has more information than the buyer, the market will gradualy deteriorate and maybe even eventually dissapear altogether. <br />
<br />
The main issue is that quality is unassesible beforehand, thus giving sellers incentives to present the product/service as being of higher quality than it actually is. The buyer, however, knows this and will take the average quality of the market into consideration. This will have as a result that high quality products/services will leave the market, since they will only sell for average market quality goods. <br />
<br />
Therefore the average market quality will deteriorate and the market will shrink.<br />
<br />
The paper also talks about the 'cost of dishonesty'.<br />
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.<br />
<br />
The name is derived from the main example Akerlof uses in his paper. He explains his theory with the used cars market, in which a bad car is called a 'lemon'.<br />
