5. (Economic Fluctuations) Why doesn’t the National Bureau ofEconomic Research identify the turning points in economic activityuntil months after they occur?


15. (Aggregate Demand and Supply) Determine whether each of thefollowing would cause a shift of the aggregate demand curve, ashift of the aggregate supply curve, neither, or both. Which curveshifts, and in which direction? What happens to aggregate outputand the price level in each case?

15. (Growth and the PPF) Use the production possibilities frontier(PPF) to demonstrate economic growth.
a. With consumption goods on one axis and capital goods on theother, show how the combination of goods selected this periodaffects the PPF in the next period.
b. Extend this comparison by choosing a different point on thisperiod’s PPF and determining whether that combination leads to moreor less growth over
the next period.

In Costa Rica, only a few beaches remain that are nesting grounds for sea turtles. Some of those beaches have communities situated near them; traditionally, the local people collected the turtle eggs and sold them for their purported aphrodisiac powers. As a result, sea turtle populations became endangered. To protect the sea turtle populations, the Costa Rican government gave each family in these villages ownership of a portion of the beach to do with as the family pleases, including the harvesting and selling of sea turtle eggs. Sea turtle populations have started to increase. The economic rationale for this action has to do with the differences between public, common, and private goods. Select an example of your choosing that would display how the government could take an action (or has actually taken one) that might change how a resource would be treated in the future. Take a look at common resources (such as the turtles) and use your own example to explain the economic rationale for a positive result.

. A recessive allele on the X chromosome is responsible for red-green color blindness in humans. This means that females have two copies (since human females are XX) and males have one copy (since human males are XY). This is called a sex-linked trait. A red-green color blind male is genotype Xn Y. A normal vision male is genotype XN Y. For this problem, a normal vision woman whose father is color-blind marries a color-blind male. N= not color blind allele, n = color blind allele. Y = Y chromosome.

a. What is the genotype of the color-blind father? Why?

b. What is the genotype of the color-blind husband? Why?

c. What is the genotype of the normal vision woman? Why?

d. What is the probability that this couple will have a son that is color-blind?

e. What is the probability that this couple will have a daughter that is color-blind?
