Question 1
Explain whether the following statements are TRUE or FALSE. State your stance clearly.
a) A positive term spread is indicative of economic recession.
b) By reducing the required reserve ratio, the central bank can increase the monetary base
and thus the money supply.
Question 2
a) What is yield curve? Explain whether it can be downward sloping.
b) If bond investors decide that 30-year bonds are no longer as desirable an investment as
they were previously, predict what will happen to the yield curve, assuming the
expectations theory of the term structure holds.
Question 3
a) What is realized real interest rate? Can a change in expected inflation rate affect the realized real
interest rate? Explain.
b) Suppose that there is an increase in expected inflation rate from 3 percent to 6 percent.
Given that the after-tax expected real interest rate remains unchanged at 2 percent and the
tax rate is 30 percent, find the original and the new nominal interest rates.
c) Suggest ONE way in which investors can reduce/avoid the risk of unexpected inflation.
Explain how it works.

State whether the question is True or False and Explain your answer. A diagram or equation may be helpful to explain your answer.
a. Constant Returns To Scale implies that doubling the inputs (e.g. capital and labor) of the production function will double output.
b. Development accounting, which is the empirical analysis that uses the production function to explain differences in GDP p.c. across countries, finds that differences in capital per capital across countries can explain MOST of the differences in GDP pc.
c. Total Factor Productivity (TFP) is usually measured empirically as an implied residual from the production function.

18. State and explain the Coase Theorem. Come up with an example of your own for which the Coase Theorem might best apply and explain how it would happen to solve the externality. Change your scenario in one small way to show how the Coase Theorem would collapse.

Please state whether each of the following statements is TRUE or FALSE, and then explain your choice briefly.
Please start your answer by writing either TRUE or FALSE. Answers without that clear statement at the beginning, and with excessively long (more than 2-3 short sentences) explanations will be penalized.
Banks can still influence the money supply if they are required to hold all deposits in reserve.
In the months of November and December, people in the U.S. hold a larger part of their money in the form of currency because they intend to shop and travel for the holidays. As a result, other things the same, the money supply increases.
Bank runs are only a concern under a fractional reserve banking system.
The money multiplier is lower when bankers are more cautious and hold excess reserves.

he Iowa Energy are scheduled to play against the Maine Red Claws in an upcoming game in the National Basketball Association (NBA) G League. Because a player in the NBA G League is still developing his skills, the number of points he scores in a game can vary substantially. Assume that each player’s point production can be represented as an integer uniform random variable with the ranges provided in the following table: Player lowa Energy Maine Red Claws 1 [5,20] [7,12] 2 [7,20] [15,20] 3 [5,10] [10,20] 4 [10,40] [15,30] 5 [6,20] [5,10] 6 [3,10] [1,20] 7 [2,5] [1,4] 8 [2,4] [2,4] Develop a spreadsheet model that simulates the points scored by each team and the difference in their point totals. (a) What are the average and standard deviation of points scored by the Iowa Energy? Round your answers to one decimal place. Average: Standard Deviation: What is the shape of the distribution of points scored by the Iowa Energy? (b) What are the average and standard deviation of points scored by the Maine Red Claws? Round your answers to one decimal place. Average: Standard Deviation: What is the shape of the distribution of points scored by the Maine Red Claws? (c) Let Point Differential = Iowa Energy points – Maine Red Claw points. What is the average Point Differential between the Iowa Energy and Maine Red Claws? What is the standard deviation of the Point Differential? If your answer is negative, enter a minus sign in the input box. Round your answers to one decimal place. Average: Standard Deviation: What is the shape of the Point Differential distribution? (d) What is the probability that the Iowa Energy scores more points than the Maine Red Claws? Round your answer to the nearest whole number. % (e) The coach of the Iowa Energy feels that they are the underdog and is considering a riskier game strategy. The effect of this strategy is that the range of each Energy player’s point production increases symmetrically so that the new range is [0, original upper bound + original lower bound]. For example, Energy player 1’s range with the risky strategy is [0, 25]. How does the new strategy affect the average and standard deviation of the Energy point total? How does that affect the probability of the Iowa Energy scoring more points than the Maine Red Claws? Round first two numerical answers to one decimal place and the last answer to a whole percentage. The average Iowa Energy point total is relatively unchanged at points, and the standard deviation of the Energy point total points. The probability of the Iowa Energy scoring more points than the Maine Red Claws %.

Background: According to museum collections from the early 1900s, the population of one beetle species in California’s central valley used to have individuals with different colors, including red, blue, yellow and brown. The beetles were found feeding on various native plants. 50 years after almond farming became widespread, most beetles were brown-colored and found living on the bark of almond trees. Observations indicate that birds are the primary predators of beetles.
Question: How and why did the population of beetles evolve to be primarily brown in color?
Your answer:
Sentence 1: Describe the variability that was initially present in the population.
Sentence 2: State which individuals in the population had the highest fitness during the event or change (if any), and why.
Sentence 3: Explain what evolutionary force acted on the population, and why and how it acted.
Sentence 4: Describe how the population evolved in response. Be as specific as you can (e.g., say “increased” or “decreased”, rather than just “changed”.)

Catherine Cooper is a 68-year-old woman scheduled for a right total knee replacement in 6 weeks. She has a history of previous injury from years of playing tennis and basketball. She states that she is concerned about the possibility of receiving a blood transfusion. She has read stories of people contracting diseases and viruses, and her friends have told her about someone who became very ill from a transfusion.
1. You are conducting Ms. Cooper's preoperative planning. How should you respond to her concerns?
2. Ms. Cooper decided to donate a unit of blood before her operation in the event that she needed transfusion therapy after surgery. She comments to you that she is so glad that she doesn't have to worry about any problems since she is receiving her own blood. What can you tell her about what to expect about her blood donation?
3. Following a type and cross, it is determined that Mrs. Cooper has AB+ blood. Which type of blood can she receive? Which type of antigens does she carry on her red blood cells?
4. Describe your responsibilities associated with initiating and monitoring the transfusion.
5. The health care provider orders another transfusion of red blood cells. Because Ms. Cooper had only 1 unit of autologous blood, she consents to a unit of allogenic blood. Within 15 minutes of the bloo
