Answer:
a) Determine which type of cars will be sold at the efficient allocation.
All cars would be sold in a Pareto efficient allocation.
In a Pareto efficient market, resources are all allocated in teh most efficient possible way. This is the reason why this is just a theoretical concept that does not necessarily apply in real life.
b) Determine which type of cars will be sold at the market equilibrium.
Since consumers are only willing to pay up to $1,620 for a used car, only medium quality and low quality cars will be sold. The price of high quality used cars is higher than the equilibrium price.
Step-by-step explanation:
the most a buyer would be willing to pay for a used car is ($1,800 x 40%) + ($1,600 x 30%) + ($1,400 x 30%) = $720 + $480 + $420 = $1,620
