A musical group called "The Grateful Dead" sold out concert after concert and typically provided a good living for scalpers (who buy tickets and resell them).Explain (using a supply and demand diagram)how The Grateful Dead's ticket pricing policy set an effective ceiling on the price of concert tickets.If there were a fixed number of seats at their concerts,what was the shape of the supply curve for these seats?

By setting a top ticket price at a level below the market-clearing price,the Grateful Dead guaranteed that there would be an excess demand for their concert tickets.This is illustrated in the diagram below.The official price (PO)effectively sets a ceiling on the price that is below the market-clearing price.At this official price,there is an excess demand for tickets (QD > QS).The supply curve for tickets was vertical,since for any given show there were only so many seats available.

Suppose that initially, the equations for demand and supply are Qd = 48 − 4P and Qs = 4P − 16, respectively. If the quantity supplied increases by 4 at every price (so that the supply curve shifts to the right), the equilibrium price will change from:

The Rent Control Authority of Chicago has found that total market demand for single occupancy apartments is Qd = 400,000 − 250 P. The Authority also noted that supply is given by Qs = 200,000 + 250P. Price of an apartment is measured in hundreds of dollars and quantity is measured in thousands of apartments. Suppose the Authority decides to impose a rent control of $300 per single-occupant apartment, how many people will be unable to find an apartment at that price?
