Chapter 5: Q 9 (page 120)

Displayed in the diagram below are conditions in the market for residential Internet access in a U.S. state. The government of this state has determined that access to the Internet improves the learning skills of children, which it has concluded is an external benefit of Internet access. The government has also concluded that if these external benefits were to be taken into account, 3 million residents would have Internet access. Suppose that the state government’s judgments about the benefits of Internet access are correct and that it wishes to offer a per-unit subsidy just sufficient to increase total Internet access to 3 million residences. What per-unit subsidy should it offer? Use the diagram to explain how providing this subsidy would affect conditions in the state’s market for residential Internet access.

Short Answer

Expert verified

The per-unit subsidy that the government should offer is $20to the internet service providers.

Step by step solution

01

Step 1. Define External Benefits.

External benefits are positive externalities that are beneficial for the economy.

02

Step 2. The per-unit subsidy.

The current rate for Internet access is $30and the number of users was 2 million. If the government wants to increase the number of users to 3 million the rate of Internet access has to be brought down to $20at which rate the suppliers could supply only 1 million users with Internet access. Since the effective price for suppliers to reach 3 million is $40 the government would have to provide a subsidy of $20per unit to the providers in order to increase the user base to 3 million at a rate of $20.

Who provides the \(16 billion paid to Medicare's "1 percent" every year- alongside the additional \)74 billion in payments to the other 99 percent of the physicians who receive payments from Medicare?

Suppose that the U.S. government determines that cigarette smoking creates social costs not reflected in the current market price and equilibrium quantity of cigarettes. A study has recommended that the government can correct the externality effect of cigarette consumption by paying farmers not to plant tobacco used to manufacture cigarettes. It also recommends raising the funds to make these payments by increasing taxes on cigarettes. Assuming that the government is correct that cigarette smoking creates external costs, evaluate whether the study’s recommended policies might help correct this negative externality.

Many economists suggest that our nation's legal system is an example of a public good. Does the legal system satisfy the key properties of public good? Explain your reasoning.

(a) In the absence of a government-subsidized health plan, what is the equilibrium price of MRI tests? What is the amount of society’s total spending on MRI tests?

(b) Suppose that the government establishes a health plan guaranteeing that all qualified participants can purchase MRI tests at an effective price (that is, out-of-pocket cost) to the individual of \)100 per test. How many MRI tests will people consume?

(c) What is the per-unit price that induces producers to provide the amount of MRI tests demanded at the government-guaranteed price of $100? What is society’s total spending on MRI tests?

(d) Under the government’s coverage of MRI tests, what is the per-unit subsidy it provides? What is the total subsidy that the government pays to support MRI testing at its guaranteed price?
