In a used car market-
Quality | Poor (lemon) | Fair | Good | Excellent |
% cars in quality | 25% | 25% | 25% | 25% |
Seller valuation | $2,000 | 4,000 | 6,000 | 8,000 |
Buyer Valuation | $4,000 | 6,000 | 8,000 | 10,000 |
Buyer does not know quality car when making offer/ competition among buyers/ buyers and sellers know probability distribution of types of cars
What price would a buyer offer a seller and what quality of car would be sold at price?
The expected value of buyer's offer = (0.25 * 4,000) + (0.25 * 6,000) + (0.25 * 8,000) + (0.25 * 10,000)
= 1,000 + 1,500 + 2,000 + 2,500
= $7,500
At a price of $7,500, good quality of car would be sold. Because for good quality cars buyer valuation is $8,000 and seller valuation is $6,000. So, at price of $7,500, seller will be willing to sell and buyer will be willing buy good quality cars.
