Multiple Choice

Suppose that the market for corn is initially in equilibrium and is perfectly competitive. The demand curve can be expressed as $P = 10 - Q ^ { d }$ ; the supply curve can be expressed as $P = 0.25 Q ^ { s }$ . Quantity is expressed in millions of bushels. Now suppose that the federal government imposes a price floor of $3 per bushel of corn. What is the dead-weight loss (per million bushels) associated with the price floor when the least efficient producers are active?
