"Market Equilibrium Price and Price Control"
Suppose there are nine sellers and nine buyers in a competitive market, each willing to buy or sell one unit of a good, with values {$10, $9, $8, $7, $6, $5, $4, $3, $2}. Assuming there are no transactions costs, what is the equilibrium price and quantity in this market?
If the government imposes a price floor at $9 (i.e., price must be $9 or higher) in the above market, how many goods will be traded?
