Document Summary

Any firm opportunity cost lower than price floor can join. In terms of efficiency, firms with lower opportunity cost (represented by supply curve) are most efficient. Cost a + cost b _____ cost best: = d. uncertain. No discipline in market so qb firms can be in market. Floor is below equilibrium therefore, price in the market is the equilibrium. Ceiling is above the equilibrium price in the market is the equilibrium price. Price ceiling can not get enough buyers in the market. Price floor has not enough firms because firms opportunity cost is higher than price ceiling. Its benefits people who have low income (it s random who benefits) Because people lobby for it or politicians think it will work. Market equilibrium and quantity price because good thing is efficient because no wasted goods. Csbest __?__ csa + csb: > b.
