There are two fishermen, Zach and Jacob. They would each benefit if lighthouses were built along the coast where they fish. The marginal cost of building a lighthouse is $100. The marginal benefit that Zach gets from each lighthouse is 90 - Q, where Q is the number of lighthouses. The marginal benefit that Jacob gets from each lighthouse is 40 - Q.
1. What is the efficient number of lighthouses?
2. What is Zach's marginal benefit of lighthouses at the efficient quantity?
3. Would Zach have been willing to pay for the last additional lighthouse at the efficient quantity?
a) Yes
b) No
1. What is market failure? Explain in your own words. 2. Why do markets fail. List two reasons and explain them in your own words. 3. Explain what an external effect (also known as an externality) is in your own words. 4. List four examples of externalities 5. Explain what a social dilemma is and list one example of a current social dilemma.
Firms A and B each produce 80 units of pollution. The federal government wants to reduce pollution levels. The marginal costs associated with pollution reduction are MCA = 50 + 3QA for firm A and MCB = 20 + 6QB for firm B, where QA and QB are the quantities of pollution reduced by each firm. Society’s marginal benefit from pollution reduction is given by MB = 590 – 3Qtot, where Qtot is the total reduction in pollution. Explain how the social optimum can be achieved if firms are given equal numbers of pollution permits but are allowed to trade

- Suppose the Environmental Protection Agency (EPA) wants to mandate that all methane emissions must be reduced to zero in order to alleviate global warming in the United States. Which of the following describes why most economists would disagree with this policy? Reducing methane emissions is desirable, but whatever levels of pollution firms decide to emit privately are already efficient. Society would not benefit from lower air pollution. The environment isn’t worth protecting. The opportunity cost of zero pollution is much higher than its benefit.arrow_forwardThe graph shows the marginal benefit and marginal cost of a waste disposal system in a city of 1 million people.

- The Cemex plant in Davenport produced cement. The production of cement created dust which traveled through the air and landed on the nearby area. Testing at an elementary school and fire department near the plant showed toxic levels of Chromium 6 resulting from the dust. Using the concept of externalities and the graph below, explain what kind of externality this event created and the effects this had on economic efficiency. Be sure to indicate any differences between market price and quantity for cement and the efficient price and quantity.arrow_forwardIf there are no externalities or market power and all markets are in equilibrium, what conclusions can we draw from this in economic theory?arrow_forwardSuppose MAC = 40 - 2E and MD = 2E.

- Bart and Lisa are kids. Their parents want to get a pet to keep them busy during a pandemic but they must choose between a dog and cat. Bart's value of the cat is $10 and his value of the dog is $40. Lisa's value of the cat is $30 and her value of the dog is $20. a. What is the efficient pet? [ Select ] ["cat", "dog"] Let's imagine that their parents flip a coin to decide who gets to choose the pet. Heads Lisa chooses and tails Bart chooses. b. If the coin comes up heads and there are no barriers to negotiation, what will Lisa choose? [ Select ] ["cat", "dog"] c.

Economists generally agree that putting a price on carbon is the best approach to reducing climate warming carbon emissions. The two main strategies for doing this are carbon taxes and the cap and trade version of emissions trading. Discuss the pros and cons to these two approaches to pricing carbon. Why do economists favor these kinds of market-based strategies to pollution control over “command and control” approaches such technology standards?arrow_forward
- The figure below shows a market in which there is an externality. The curve S2 is parallel to S1. Areas in the figures are numbered. What type of externality is shown in the figure and why is it a problem in economics? Identify the market equilibrium and the social equilibrium in the figure. If the market were to move from the market equilibrium to the social equilibrium, indicate the area(s) that represent the change in consumer surplus, the change in producer surplus, the change for third parties, and the net effect on total surplus. Does total surplus rise or fall? What would be the amount of a per-unit tax needed to fix the externality?arrow_forwardThe following data refers to the number of logging operations working in a stretch of tropical rainforest per week.
