In Maine, you must have a license to harvest lobster commercially; these licenses are issued yearly. The state of Maine is concerned about the dwindling supplies of lobsters found off its coast. The state fishery department has decided to place a yearly quota of 80,000 pounds of lobsters harvested in all Maine waters. It has also decided to give licenses this year only to those fishermen who had licenses last year. The accompanying figure shows the demand and supply curves for Maine lobsters. a. In the absence of government restrictions, what are the equilibrium price and quantity? b. What is the demand price at which consumers wish to purchase 80,000 pounds of lobsters? c. What is the supply price at which suppliers are willing to supply 80,000 pounds of lobsters? d. What is the quota rent per pound of lobster when 80,000 pounds are sold? e. Find an excise tax that achieves the same reduction in the harvest of lobsters. Show it on the figure. What is the government revenue collected from this tax? f. Explain a transaction that benefits both buyer and seller but is prevented by the quota restriction. Explain a transaction that benefits both buyer and seller but is prevented by the excise tax.

Key Concepts

Excise Tax as a Policy Tool

An excise tax is a per-unit tax imposed on a good that can be used to curtail consumption, similar in effect to a quota. It shifts the supply curve upward by the amount of the tax, thereby reducing the equilibrium quantity. When carefully calibrated, an excise tax can achieve the same reduction in the harvested quantity as a quota, while generating revenue for the government. This tool is of interest in policy-making for its dual economic regulatory and fiscal benefits.

Welfare Effects and Prevented Beneficial Transactions

Government interventions, such as quotas and excise taxes, often restrict transactions that would have otherwise been mutually beneficial to buyers and sellers. These prevented transactions lead to a loss of potential consumer and producer surplus, known as deadweight loss. Understanding these welfare effects is crucial, as they highlight the trade-offs between achieving policy objectives (like resource conservation) and the efficiency costs that such restrictions impose on market outcomes.

Supply Curve

The supply curve represents the relationship between the price received by producers and the quantity of a good they are willing to supply. Typically, it slopes upward, indicating that higher prices incentivize producers to supply more of the good. Determining the price on the supply curve corresponding to a specific quantity reveals the least price at which suppliers are willing to sell that amount, which is essential for assessing producer surplus and the consequences of policy interventions.

Market Equilibrium

Market equilibrium occurs at the intersection of the demand and supply curves where the quantity demanded equals the quantity supplied at a particular price. This concept is fundamental in microeconomics because it represents the price and quantity at which the market clears without any excess supply or demand, and it serves as a benchmark to analyze the effects of external interventions such as quotas or taxes.

Demand Curve

The demand curve illustrates the relationship between the price that consumers are willing to pay and the quantity demanded of a good. It generally slopes downward, signaling that as the price decreases, consumers are willing to purchase more. Evaluating the demand curve at a specific quantity helps identify the maximum price consumers are willing to pay for that quantity, which is crucial for understanding consumer surplus and the overall impact of market restrictions.

Quota Restrictions and Quota Rent

A quota is a government-imposed limitation on the amount of a good that can be produced or sold, which, in turn, creates a scarcity relative to the free market equilibrium. The quota rent refers to the extra profit accrued due to the artificially limited supply—the difference between the market value of the scarce good and the minimum price at which suppliers are willing to offer it. This concept is significant as it illustrates how regulatory measures can lead to income transfers or economic inefficiencies.
