How do you find EV in lemons market?
EV=1200(1−q)+2400q
1200 =The buyer’s max willingness to pay for a lemon
2400 = The buyer’s max willingness to pay for a peach
q = The probability (share) of peaches in the market
1-q = The probability of getting a lemon
if EV < 2000 (the peach seller’s minimum acceptable price), peaches will exit the market.
