Demand: Qd=90-4P, where Qd is quantity demanded and P is price Supply: Qs=-100+15P, where Qs is quantity supplied and P is price Recall that equilibrium price was 19, while quantity was 50. At that price, the price elasticity of demand was -0.80. Now I want you to rearrange each equation, putting P on the left-hand side, and solve again for equilibrium P and Q (you ought to get the same answer). Now we want to figure the monopoly price. Take...

Suppose the demand function for corn is Qd = 10-2p, and supply function is Qs = 3p-5. The government is concerned that the market equilibrium price of corn is too low and would like to implement a price support policy to protect the farmers. By implementing the price support policy, the government sets a support price and purchases the extra supply at the support price and then gives it away to the consumers free. The government sets the support price...
