Summarize the effects of a subsidy on the market price and the quantity produced.

A subsidy increases the price received by sellers, shifts the supply curve rightward, and places a wedge between the marginal social benefit and marginal social cost of producing the good. The subsidy creates a deadweight loss, a higher equilibrium quantity sold, over-production, and a lower price paid by the consumers. The subsidy increases farm revenues to all farmers.

Explain why a voluntary production quota is difficult to operate

A voluntary quota is difficult to operate because a production quota results in a massive incentive to "cheat" on the production quota by increasing production. A production quota decreases the quantity produced. By decreasing the quantity produced, a production quota raises the price and reduces the marginal social cost of the last unit produced. Because the price exceeds the marginal social cost, producers have an incentive to increase their production (beyond the quota amount) to boost their profit.

How does the imposition of a penalty for selling or possessing an illegal drug influence demand, supply, price, and the quantity of the drug consumed?

If buyers and sellers face penalties, both the demand and supply curves shift leftward. If the shift of the supply curve is larger, the equilibrium price rises and quantity decreases; if the shift of the demand curve is larger, the price falls and quantity decreases; if the shifts are the same magnitude, the price is unchanged and the quantity decreases.

How does the imposition of a penalty for possessing an illegal drug influence demand, supply, price, and the quantity of the drug consumed?

If the penalty is levied on the buyer, the penalty is subtracted from the maximum willingness to pay for the good. The supply curve remains unchanged and the demand curve shifts leftward, so that the vertical distance between the initial demand curve and the demand curve with the penalty equals the dollar value of the penalty. In this case, the equilibrium price of the good falls and the equilibrium quantity decreases.

How does the imposition of a penalty for selling an illegal drug influence demand, supply, price, and the quantity of the drug consumed?

If the penalty is levied on the seller, the penalty is added to the minimum price Required for supplying the good or service. The demand curve remains unchanged but the supply curve shifts leftward, so that the vertical distance between the initial supply curve and the supply curve with the penalty equals the dollar value of the penalty. In this case, the equilibrium price of the good rises and the equilibrium quantity decreases.

how does the elasticity of supply influence the incidence of a tax, the quantity bought, the tax revenue, and the deadweight loss?

The more elastic the supply for a given demand the larger the increase in the price paid by the buyers and the smaller the decrease is the price received by the sellers, which means that the incidence on buyers is larger. Additionally, the more elastic the supply, the smaller the quantity bought so the smaller the tax revenue and the larger the deadweight loss.

Is there any case for legalizing drugs?

To reduce the consumption of drugs, they can be legalized and taxed. Legalizing and then taxing drugs has the benefit of raising funds for the government that could be used to help educate people about the danger of consuming drugs. However, if very high taxes are necessary to reduce the consumption of illegal drugs to the level of use when they were banned, this will cause buyers and sellers to engage in unreported trade in the black market and avoid the tax through tax evasion.

explain why a minimum wage creates an inefficient allocation of labor resources

a competitive labor market allowed to reach its equilibrium creates an efficient allocation of resources. At the equilibrium, the amount of employment is such that the marginal social cost of labor to workers equals the marginal social benefit from labor to firms. A minimum wage set above the equilibrium wage rate creates a surplus of labor - the quantity of labor supplied exceeds the quantity of labor demanded. The minimum wage reduces employment so that it is less than the efficient amount.

what is a minimum wage and what are its effects if it is set above the equilibrium wage?

a minimum wage is a price floor applied to the labor market. A minimum wage Is a government imposed regulation that makes it illegal to charge (or pay) a wage rate lower than a specified level. If the minimum wage is set above the equilibrium wage, it creates a surplus of labor-unemployment-and decreases workers' and firms' surplus

explain why a production quota is inefficient.

a production quota is inefficient because it decreases production. As a result the marginal social benefit of the last unit produced exceeds the marginal cost. Because the marginal benefit exceeds the marginal social cost, there is a deadweight loss

summarize the effects of a production quota on the market price and the quantity produced.

a production quota set below the equilibrium quantity raises the price and decreases the quantity.

why does a rent ceiling create an inefficient and unfair outcome in the housing market?

a rent ceiling creates inefficiency because at the quantity of apartments that are rented, the marginal social benefit exceeds the marginal social cost. Rent ceilings are unfair under the "fair rules" approach because rent ceilings prevent voluntary transactions. Rent ceilings are unfair under the "fair results" approach because there is no assurance that apartments go to those with lower incomes. Indeed, rent ceilings lead to discrimination, which is perhaps the antithesis to fairness.

what is a rent ceiling and what are its effects if it is set above the equilibrium rent?

a rent ceiling is a specific example of price ceiling. A rent ceiling is a government imposed regulation that makes it illegal to charge a rent higher than a specified level. If a rent ceiling is set above the equilibrium rent, it has no effect because it does not make the equilibrium rent illegal.

When would a tax be efficient?

a tax is efficient, that is, creates no deadweight loss, when demand is perfectly inelastic or supply is perfectly inelastic. In both these cases a tax does not change the quantity produced and so creates no deadweight loss.

explain how scarce jobs are allocated when a minimum wage is in place

if a minimum wage is set above the equilibrium wage, the ability of the competitive market to allocate resources is thwarted and other means must be used. Sometimes the method used is first-come, first-served so that those who are first in line to apply for openings are given the jobs. Other times discrimination is used so that those from favoured groups are allocated the jobs.

what are the effects of a minimum wage set below the equilibrium wage?

if the minimum wage is set below the equilibrium wage, then the law has no impact on the labor market equilibrium wage and quantity.

what are the effects of a rent ceiling that is set below the equilibrium rent?

if the rent ceiling is set below the equilibrium rent, the quantity of housing units demanded by renters exceeds the quantity supplied by landlords. Since landlords are not forced to supply more units than the supply curve would indicate for the rent ceiling price, the quantity of housing units actually rented equals the quantity supplied, rather than the quantity demanded. This causes a shortage in the rental housing market.

how does the elasticity of demand influence the incidence of a tax, the tax revenue, and the deadweight loss?

the more elastic the demand for a given supply, the smaller the increase in the price paid by the buyers and the greater the decrease in the price received by the sellers, which means that the incidence on buyers is smaller. Additionally, the more elastic the demand, the smaller the quantity bought so the smaller the tax revenue; and the larger the deadweight loss.

what are the two principles of fairness that are applied to tax systems?

the two principles of fairness are the benefits principle and the ability-to-pay principle. The benefits principle asserts that people should pay taxes equal to the benefits they receive from the government provided services. The ability-to-pay principle asserts that people should pay taxes according to how easily they can bear the burden of the tax.

Explain why a subsidy is inefficient.

A subsidy creates inefficiency because a subsidy leads to a lower price and increased production. Marginal social benefit equals the price and so the lower price signals that the marginal social benefit falls. And the increased production means that the marginal social cost of production rises. So at the level of production with a subsidy, the marginal social benefit is less than the marginal social cost and inefficiency is created.

Why is a tax inefficient?

the imposition of a tax on a market causes a wedge to be driven between the price received by the seller and the price paid by the buyer. This causes the marginal social benefit from the last unit sold to be higher than its marginal social cost, and the market will under produce the good or service being taxed. If more of the good or service were produced, the marginal social benefit gained would be greater than the marginal social cost incurred, and the net benefit to society would increase.

how are scarce housing resources allocated when a rent ceiling is in a place?

with an effective rent ceiling, some means for allocation of housing units (other than by price) becomes necessary. Some housing is allocated by first-come, first-serve. Other housing is allocated by discrimination. Black markets also develop, where housing units are allocated at a rent higher than the regulated rent.

explain why a minimum wage is unfair.

workers who receive wage hikes and retain their jobs gain from the minimum wage but workers who lose their jobs and workers who must extensively search for a job lose. Those who keep (or find) jobs are not necessarily the least well off, so the minimum wage fails the fare results approach to fairness. And the minimum wage also fails the fair rules approach to fairness because the minimum wage blocks voluntary transactions that otherwise would occur.
