The Gizmo Company is planning to develop new household gadgets. Table 13.4 shows the companys demand for financial capital for research and development of these gadgets, based on expected rates of return from sales. Now, say that every investment would have an additional 5 social benefitâ€”that is, an investment that pays at least a 6 return to the Gizmo Company will pay at least an 11 return for society as a whole; an investment that pays at least 7 for the Gizmo Company will pay at least 12 for society as a whole, and so on. Answer the questions that follow based on this information. If the going interest rate is 9, how much will Gizmo invest in R. How much will the firm invest if it also receives the social benefits of its investment? (Add an additional 5 return on all levels of investment.)
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?
Becky and Sarah are sisters 1who share a room. Their room can easily get messy, and their parents am always telling them to tidy it. Here are the costs and benefits to both Becky and Sarah, of taking the time to clean their room: If both Becky and Sarah clean, they each spends two hours and get a clean room. If Becky decides not to clean and Sarah does all the cleaning, then Sarah spends 10 hours cleaning (Becky spends 0) but Sarah is exhausted. The same would occur for Becky if Sarah decided not to cleanâ€”Becky spends 10 hours and becomes exhausted. If both girls decide not to clean, they both have a dirty room. What is the best outcome for Becky and Sarah? What is the worst outcome? (It would help you to construct a prisoners dilemma table.) Unfortunately, we know that the optimal outcome will most liker not happen, and that the sisters probably will choose the worst one instead. Explain what it is about Beckys and Sarahs reasoning that will lead them both to choose the worst outcome.
