Answer:
Fraction x = 0.8
Step-by-step explanation:
As we know that consumers value a non-defective car at $11,000, so we make assumption that only used cars for sale will be defective ones.
The used car price of $6000 is the value to consumers of a defective car.
For a risk-neutral buyer, the reservation price for a new car will be the expected value of a non-defective car( i.e., the value of a good car times the probability of getting a good car, plus the value of a bad car times the probability of getting a bad car.)
So to find x, we solve:
Expected value = (prob. of non-defective car) (value of non-defective car)
+ (prob. of defective car)(value of defective car)
$7000 = ( 1 − x )11,000 + ( x )6000
7000= 11000 - 11000x + 6000x
5000x = 4000
x = 4000/5000
x= 0.8
