According to lecture, evaluating the abundance, and thus health, of fish stocks in pelagic fisheries like the Cod fishery in terms of steady catch rates or profits from fishing, is problematic because it: OIgnores the role that increasingly efficient fishing technology plays in keeping catches and profits steady, when fish populations may be declining O Assumes every fisherman is reporting their profits and catches accurately OIs based on estimates rather than hard numbers regarding catch and profit O Ignores the fact that pelagic fishers, like the cod fishery off the NE coast of North America, is regulated by community-based resource management

- What is an externality?Consider two ways of protecting elephants from poachers in African countries. In one approach, the government sets up enormous national parks that have sufficient habitat for elephants to thrive and forbids all local people to enter the parks or to injure either the elephants or their habitat in any way. In a second approach, the government sets up national parks and designates 10 villages around the edges of the park as official tourist centers that become places where tourists can stay and bases for guided tours inside the national park. Consider the different incentives of local villagers-who often are very poor-in each of these plans. Which plan seems more likely to help the elephant population?warten population manghe ecosystem's Carrying capacity? 6. We have the following data for Demand Price and Costs for our product. Quantity Demand Price Costs 300 100 $21.63 $35.35 $5040.00 $2347.67 500 $17.25 $7481.67 1000 $12.70 $12469.67 1500 $10.26 $16196.00 We have reason to believe that the Demand Price is a power (exponential) function of some kind. Our Cost function is close to linear, but we expect, from some market analysis, that it is in fact quadratic. Approximate this data with a Demand Price function and a Cost function. Explain how confident you are; that is, how much error do you think is reasonable in this type of scenario? 区
- . Appalachian Coal Mining believes that it can increase labor productivity and, therefore, net revenue by reducing air pollution in its mines. It estimates that the marginal cost function for reducing pollution by installing additional capital equipment is MC=40P Where P represents a reduction of one unit of pollution in the mines. It also feels that for every unit of pollution reduction the marginal increase in revenue (MR) is MR=1000-10P How much pollution reduction should Appalachian Coal Mining undertake?"Wearing mask and using the sanitizer has helped in controlling the spread of COVID-19".

Overfishing of this species, particularly in the Mediterranean Sea, has led to the strong possibility of extinction. The graph illustrates the marginal social cost (MSC), marginal private cost (MPC), and marginal social benefit (MSB) for a hypothetical representation of the Bluefin tuna market. Use the graph to answer the questions. What is the socially optimal price and quantity?
- cap-and-trade and windfall profitsA city called Seoul is suffering from high concentrations of mercury in the air, caused by burningcoal in power plants. There are two of these plants close to the city. The city’s mayor wants touse cap-and-trade to reduce emissions to a reportedly “safe” level of 60 tons. The two firms havethe following marginal benefits of emissions: MB1 = 100 – 2e1, MB2 = 25 – 0.5e2.a. How much mercury will each firm emit? What allowance price will prevail in themarket?Firm 2 hires a smart lobbyist who convinces the government that its profits are relatively low andthat it therefore deserves a generous allowance allocation. The government agrees and allocatesa1 = 20 allowances to firm 1 (for free) and a2 = 40 allowances to firm 2 (for free).b. What are the firms’ profits? Do any of the firms earn windfall profits?
