a)In anautarkic(closed) economy, the national equilibrium price for good A is $1,000 per unit and total consumption amounted to 1000 units. If the maximum price consumers are willing to pay for this good is $1,400 per unit at 0 units of output, calculate the consumer surplus. Suppose at a minimum price of $400 per unit,the producer's output is 0 units but will produce 1000 units at the equilibrium price of $1,000, calculate the producer surplus.

b) Who is better off, the consumer or the producer and why?
