Lorenzo and Neha are farmers. Each one owns a 12-acre plot of land. The following table shows the amount of alfalfa and barley each farmer can produce per year on a given acre. Each farmer chooses whether to devote all acres to producing alfalfa or barley or to produce alfalfa on some of the land and barley on the rest. Alfalfa Barley (Bushels per acre) (Bushels per acre) Lorenzo 40 8 Neha 28 7 On the following graph, use the blue line (circle symbol) to plot Lorenzo's production possibilities frontier (PPF), and use the purple line (diamond symbol) to plot Neha's PPF.

3. Suppose you currently earn $80,000 a year. You are considering a job that will increase your lifetime earnings by $400,000 but that requires an MBA. The job will mean also attending business school full time for two years at an annual cost of $70,000. You already have a bachelor’s degree, for which you spent $150,000 in tuition and books. a. Which of the above information is relevant to your decision on whether to take the job? b. What is the opportunity cost of going to school to study MBA? c. Should you take the job? [Note: You will need to get the MBA]

7. After receiving good reviews for her work at a series of art shows, Jean Rodin considers quitting her job as a management consultant to pursue full time her hobby of sculpting. Jean figures that she can sell $100,000 worth her art each year. She found a studio that she can rent for $2,000 per month and know that materials will cost her $20,000 per year. She now earns $90,000 per year. If her calculations are correct, Jean's annual economic profits from the venture will be. a) $80,000 b) $56,000 c) $10,000 d) -$34,000

4. Kristen and Anna live in the beach town of Santa Monica. They own a small business in which they make wristbands and pot holders and sell them to people on the beach. As shown in the table on the following page, Kristen can make 15 wristbands per hour but only 3 pot holders. Anna is a bit slower and can make only 12 wristbands or 2 pot holders in an hour. OUTPUT PER HOUR WRISTBANDS POT HOLDERS Kristen 15 Anna 12 2 a. For Kristen and for Anna, what is the opportunity cost of a pot holder? Who has a comparative advantage in the pro- duction of pot holders? Explain your answer. b. Who has a comparative advantage in the production of wristbands? Explain your answer. c. Assume that Kristen works 20 hours per week in the busi- ness. Assuming Kristen is in business on her own, graph the

what is the solution with this one?

Antonio and Caroline are farmers. Each one owns a 20-acre plot of land. The following table shows the amount of alfalfa and barley each farmer can produce per year on a given acre. Each farmer chooses whether to devote all acres to producing alfalfa or barley or to produce alfalfa on some of the land and barley on the rest.   Alfalfa Barley (Bushels per acre) (Bushels per acre) Antonio 40 8 Caroline 28 7   ___________has an absolute advantage in the production of alfalfa, and __________  has an absolute advantage in the production of barley.   Antonio's opportunity cost of producing 1 bushel of barley is ____   bushels of alfalfa, whereas Caroline's opportunity cost of producing 1 bushel of barley is______   bushels of alfalfa. Because Antonio has a ______ opportunity cost of producing barley than Caroline,________ has a comparative advantage in the production of barley and_______ has a comparative advantage in the production of alfalfa.

1. According to part A of Table 5-1, what education level loses most (i.e., has the greatest decrease in wage) from immigration to the United States? Does this result depend on keeping the rental on capital constant? Explain why or why not. 2. Suppose that computers use 2 units of capital for each worker, so that KC = 2 • LC, whereas shoes use 0.5 unit of capital for each worker, so that KS = 0.5 • LS. There are 100 workers and 100 units of capital in the economy. a. Solve for the amount of labor and capital used in each industry. Hint: The box diagram shown in Figure 5-7 means that the amount of labor and capital used in each industry must add up to the total for the economy, so that Use these two equations to solve for LC and LS, and then calculate the amount of capital used in each industry using KC = 2 • LC and KS = 0.5 • LS. b. Suppose that the number of workers increases to 125 due to immigration, keeping total capital fixed at 100. Again, solve…
