Under a price ceiling, bribery is a mechanism to:

A)	bring the total price of a good (including the bribe) lower and closer to the equilibrium price.

B)	bring the total price of a good (including the bribe) higher and closer to the equilibrium price.

C)	allocate a good to the richest individuals in the market.

A price ceiling is an upper limit on the price a supplier can charge. If the ceiling is below the equilibrium price, it can result in bribes as a rationing mechanism, whereas the total price of a good (including the bribe) is brought closer to the equilibrium price.

Which of the following most accurately describes the impact of a price ceiling set below the equilibrium price for a good and a minimum wage set above the equilibrium wage, respectively?

A)	Shortage; decreased unemployment.

B)	Surplus; increased unemployment.

C)	Shortage; increased unemployment.

A ceiling that is below the equilibrium price for a good will result in a shortage characterized by a quantity demanded that is greater than the quantity supplied. A minimum wage leads to increased unemployment as firms tend to substitute capital for labor. Even though there are often a large number of unemployed low-skilled workers who may be willing to work at a wage lower than the minimum wage, firms cannot legally hire them.

If a price ceiling is above the equilibrium price in a given market, its effect will most likely be:

nothing.

B)	a surplus.

C)	a shortage.

A ceiling is only effective if it is below the equilibrium price. If it is above the equilibrium price, then it should have no effect. If the ceiling is below the equilibrium price, it will produce a shortage. In such a case, suppliers do not produce as much as consumers wish to buy at the ceiling price.

New legislation setting a price ceiling will most likely cause:

A)	a market surplus.

B)	a market shortage.

C)	a decrease in demand.

Price ceilings restrict the producer from increasing the selling price. The lower price will stimulate demand by consumers at this lower price. However, since producers will not be able to increase price there is little incentive for them to increase supply. Hence, production and supply will be limited at the price ceiling leading to a market shortage.
