Try the following exercises to better understand how the national debt is related to the government budget deficit.

1. Assume that the gross national debt initially is equal to $3 trillion and the federal government then runs a deficit of $300 billion:

a. What is the new level of gross national debt?

b. If 100 percent of the deficit is financed by the sale of securities to federal agencies, what happens to the amount of debt held by the public? What happens to the level of gross debt?

c. If GDP increased by 5 percent in the same year that the deficit is run, what happens to gross debt as a percentage of GDP? What happens to the level of debt held by the public as a percentage of GDP? (You will need to figure out which is growing faster, GDP or the gross debt, and then GDP and debt held by the public. If gross debt is growing faster than GDP, then gross debt as a percentage of GDP will increase.)

2. Now suppose that the gross national debt initially is equal to $2.5 trillion and the federal government then runs a deficit of $100 billion:

a. What is the new level of gross national debt?

b. If 100 percent of the deficit is financed by the sale of securities to the public, what happens to the level of debt held by the public? What happens to the level of gross debt?

c. If GDP increases by 6 percent in the same year as the deficit is run, what happens to gross debt as a percentage of GDP?  (You will need to figure out which is growing faster, GDP or the gross debt. If gross debt is growing faster than GDP, then gross debt as a percentage of GDP will increase.)

An investment fund owns $15,000,000 principal of a corporate bond whose modified duration ​is -8.3 (years). The bond's current percentage-of-par price is 108.58% (1.0858). The fund ​may sell the bond in several weeks as part of a portfolio restructuring, and is worried that ​bond yields will rise and prices decline. So it decides to hedge its risk using another bond ​whose modified ​duration is -9.0 (years), the most liquid bond available.

​These are the relevant prices today:

​​Target bond: ModDur = -8.3. ​Percentage-of-par price: 108.58% (1.0858)

​​Hedge bond: ModDur = -9.0.    Percentage-of-par price: 103.59% (1.0359)

​Three weeks later, the fund sells its bond and covers its hedge. Prices then are:

​​Target bond: Percentage-of-par price: 105.00% (1.0500)

​​Hedge bond: Percentage-of-par price: 99.89% (0.9989)

​[NOTE: for this problem remember the distinction between the principal amount of a bond ​and its value, which is principal × decimal format price.]

​a.​What is the anticipated transaction?

​b. ​What can be done to hedge this risk? (i.e. buy/sell? what? how much in principal, how ​​much in value?)

​c.​How much does the firm pay/receive when it carries out the anticipated transaction?

​d.​What does the firm do to cover the hedge position? Did the hedge transaction produce ​​a profit or a loss, and how much?

​e.​Combining the results of the anticipated transaction and the hedge, what is the ​​​effective price of the overall transaction?

2. Bigger sample is not always better – one of the worst statistical mistakes ever made in the history of statistics happened in the 1936 U.S. Presidential Election. The incumbent president Franklin Roosevelt of the Democratic Party and Alf Landon of the Republican Party are the two main presidential candidates. Look the event up at this webpage http://www.math.upenn.edu/~deturck/m170/wk4/lecture/case1.html and answer the following questions.

1. Find the Literary Digest’s pre-election prediction for Roosevelt and Landon, in percentage of popularity vote. (One percentage for Roosevelt and one for Landon.)
2. Find the 1936 Presidential election result for Roosevelt and Landon, in percentage of popularity vote.

(One percentage for each.)

3. Find the sample size used by Literary Digest.
4. The Literary Digest’s sample has a problem with the selection bias. Identify the target population, sampling frame and briefly explain why there was a selection bias.
5. The Literary Digest’s sample also has a problem with the non-response bias. Report the number of surveys sent, number of surveys received, and calculate the non-response rate (in %).
6. The Literary Digest’s sample has a problem with the response bias. Mind you that the US is in their eighth year of the Great Depression. Briefly explain how the Great Depression has anything to do with the response bias.
7. Find the sample size used by George Gallop.
8. What was his (George Gallup’s) pre-election prediction for Roosevelt, in percentage of popularity vote? (Please look this question (h) up on the internet. The numbers may vary from different sources or web sites. Just pick one and it will not be marked based on the accuracy of the numbers.)

Using techniques from an earlier section, we can find a confidence interval for μ_d. Consider a random sample of n matched data pairs A, B. Let d = B − A be a random variable representing the difference between the values in a matched data pair. Compute the sample mean

d

of the differences and the sample standard deviation s_d. If d has a normal distribution or is mound-shaped, or if n ≥ 30, then a confidence interval for μ_d is as follows.

d − E < μ_d < d + E

where E = t_c

c = confidence level (0 < c < 1)

t_c = critical value for confidence level c and d.f. = n − 1

(a) Using the data above, find a 95% confidence interval for the mean difference between percentage increase in company revenue and percentage increase in CEO salary. (Round your answers to two decimal places.)

(b) Use the confidence interval method of hypothesis testing to test the hypothesis that population mean percentage increase in company revenue is different from that of CEO salary. Use a 5% level of significance.

Since μ_d = 0 from the null hypothesis is in the 95% confidence interval, reject H₀ at the 5% level of significance. The data do not indicate a difference in population mean percentage increases between company revenue and CEO salaries.Since μ_d = 0 from the null hypothesis is not in the 95% confidence interval, do not reject H₀ at the 5% level of significance. The data indicate a difference in population mean percentage increases between company revenue and CEO salaries.    Since μ_d = 0 from the null hypothesis is in the 95% confidence interval, do not reject H₀ at the 5% level of significance. The data do not indicate a difference in population mean percentage increases between company revenue and CEO salaries.Since μ_d = 0 from the null hypothesis is not in the 95% confidence interval, reject H₀ at the 5% level of significance. The data indicate a difference in population mean percentage increases between company revenue and CEO salaries.

(2 points) b) A product whose EOQ is 100 units experiences an increase in ordering cost from $10 per order to $40 per order. The revised EOQ is? (2 points) c) A product has a demand of 4000 units per year. Ordering cost is $40, and holding cost is $4 per unit per year. The lead-time is doubling from 2 days to 4 days, what is the impact to the economic order quantity? Why? (2 points) d) A production order quantity problem has a daily demand rate = 25 and a daily production rate = 100. The production order quantity for this problem is 500 units. What is the average inventory for this problem? (2 points) e) The new office supply discounter, Paper Clips, Etc. (PCE), sells a certain type of ergonomically correct office chair that costs $500. The holding cost per unit per year is 25% of the item cost, annual demand is 6000 units, and the ordering cost is $80 per order. The lead time is normally distributed and on average takes 12 days with a standard deviation of 2 day. Because demand is variable (standard deviation of daily demand is 5 chairs), PCE has decided to establish a customer service level of 90% (Z=1.28). The store is open 300 days per year.
