Suppose the supply curve for cans of soda in your dorm is given by P = .20 + .001 Q, where P is price and Q is the number of cans sold per day.  The demand curve for cans of soda in the dorm is given by P = .80 - .002 Q.

 a.      Find the equilibrium price and quantity of soda cans per day sold in the dorm.

a.      If your neighbor makes her decision without considering your orchard, will she keep the bees?  Yes  No

b.  Is it socially optimal for your neighbor to keep the bees?  Yes No

c.      If your neighbor consults with you, will she decide to keep the bees? That is, will you and she agree on a compensation scheme if she keeps the apiary in business?Yes
