Suppose that the market for corn is initially in equilibrium and is perfectly competitive. The demand curve can be expressed as P=10QdP = 10 - Q ^ { d } ; the supply curve can be expressed as P=P = 0.25Qs0.25 Q ^ { s } . Quantity is expressed in millions of bushels. What is the equilibrium quantity traded and price in this market?

Suppose that the market for corn is initially in equilibrium and is perfectly competitive. The demand curve can be expressed as P=10QdP = 10 - Q ^ { d } ; the supply curve can be expressed as P=P = 0.25Qs0.25 Q ^ { s } . Quantity is expressed in millions of bushels. Now suppose that the federal government imposes a price floor of $3\$ 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?

Suppose that the market for cigarettes is initially in equilibrium and is perfectly competitive. The demand curve can be expressed as P=60QdP = 60 - Q ^ { d } ; the supply curve can be expressed as P=P = 0.5Qs0.5 Q ^ { s } . Quantity is expressed in millions of boxes per month. Now suppose that the federal government imposes a production quota on cigarettes of 30 million boxes per month. What is the level of excess supply in this market?
