Macroeconomics chapter
Economists believe that the German government could have averted the hyperinflation if it had responded to its situation by: ▼ Decreasing Increasing taxes, ▼ borrowing from lending to the public and ▼ paying defaulting on its debt.
increasing borrowing from defaulting on
Why is the unemployment rate, as measured by the Bureau of Labor Statistics, an imperfect measure of the extent of joblessness in the economy?
All of the above.
The process of critical thinking is useful in macroeconomics because:
Macroeconomics is focused on choosing effective policies.
In April 2012, the Bazanian Daily, a leading newspaper in the country of Bazania, carried a report titled "20,000 jobs added in the last quarter; unemployment rate shoots up from 5 percent to 6.7 percent." How could the unemployment rate in Bazania increase even when new jobs were created?
. The new jobs may have made discouraged workers optimistic enough to start applying for jobs, thus re-entering the labor force and being counted as unemployed, which causes the overall unemployment rate to increase.
In August, 1979, the annual rate of inflation in the U.S. was nearly 12%, and the U.S. short-term nominal interest rate was nearly 10%. Over the next 35 years, both the rate of inflation and short-term nominal interest rate tended to fall. By August 2014, the rate of inflation was about 2% and the short-term nominal interest rate was close to 0%. How has the real short-term interest rate changed from 1979 to 2014?
. The real rate remained stable at −2%.
Positive
1. Families where both parents earn high wages (high opportunity cost of time) are more likely to both work at a paid job and hire outside help for household chores than otherwise similar families where parents earn low wages (low opportunity cost of time).
Recall from the chapter that banks in the United States hold a fraction of their checking deposits as reserves, either as vault cash or as deposits with the Federal Reserve (where they earn very little interest). Regulations require them to hold a certain percentage (currently 10 percent) of their checking deposits as reserves. However, banks are free to hold additional reserves if they choose. The latter are called excess reserves. Ordinarily, banks held very few excess reserves. However, starting in the financial crisis of 2007-2009, the amount of excess reserves held by banks went from virtually zero to over 1.8 trillion dollars. Explain why banks would be expected to try to minimize the amount of excess reserves that they hold.
All of the above.
What other reasons might explain why unemployment is lower among workers with a relatively higher level of education?
All of the above.
This implies that if the money supply grows by 10 percent, then nominal GDP needs to grow by ▼ .
10 percent
Normative
2. Parents should carefully weigh all the costs and benefits, including their preferences and values, when deciding how to care for children.
The economy witnessed the sharpest change in the unemployment rate from ____________.
2008 to 2009 as a result of the financial crisis that hit the United States starting in late 2007.
Normative
3. Some economists recommend granting unpaid leave to parents after the birth of a child because they calculate that the benefits exceed the costs.
What steps do bank regulators take to prevent SIFIs from failing or to minimize the effect of such failures?
All of the above.
When the economy is at full employment,
All of the above.
Which of the following is an example of what economists refer to as job search?
All of the above.
Why do the inflation rate and the nominal interest rate tend to move together over the long-run?
A and B only.
What is the difference between nominal and real interest rates?
A and C only.
What is deposit insurance?
A program implemented in most countries to protect bank depositors, in full or in part, from losses caused by a bank's inability to pay its withdrawals.
Caveat lector is:
A summary of the argument that one should be skeptical when gathering information.
What are the two models that are used to describe inflationary expectations? (Check only two.)
Adaptive expectations. Rational expectations.
According to this Evidence Based Economics (EBE) feature, the following factors set the stage for the German hyperinflation after World War I:
All of the above
Suppose that you allocate $20 each week for your entertainment budget. This money is spent on two items: either renting movies for $1 each at Redbox or downloading songs from iTunes at $1 each. Given this information, which of the following would represent your budget constraint for entertainment?
Amount spent on iTunes + Amount spent at Redbox = $20.
Which of the following is not one of the factors that can increase wage rigidity in the labor market?
An increase in the time needed to search for available jobs.
Households and firms with savings lend money to banks and other financial institutions. The credit supply curve shows the relationship between the quantity of credit supplied and the real interest rate. The credit supply curve slopes upward because a ____________.
B and C only.
If a bank runs short of reserves, a reasonable step would be to ____________.
B and C only.
If narrow banking reduces systemic risk, why do banks still practice maturity transformation?
Banks still practice maturity transformation simply because it is generally very profitable to do so.
Usury laws place an upper limit on the nominal rate of interest that lenders can charge on their loans. In the 1970s, some credit card companies moved to states where there were no ceilings on interest rates to avoid usury laws. Why would credit card companies move to states without usury laws during a period of high inflation, like the 1970s?
Because usury law ceilings may limit the real return lenders can earn during inflationary periods, lenders have an incentive to move to states without such laws.
Which of the following does not cause the labor supply curve to shift?
Changes in the wage rate paid to workers.
Which of the following statements about the role of communication in the process of critical thinking is false?
Communication can play a role, but more often than not its role is not important.
The federal funds rate is the ____________.
interest rate in the federal funds market where banks obtain overnight loans of reserves from one another.
The process of thinking critically is best described as:
Deciding what the issue is, becoming aware of your initial frame of reference, gathering information, and constructing a conclusion.
Which of the following is not a part of the critical thinking step of gathering relevant information?
Deciding which possible answer you gather is the right one.
Suppose your New Year resolution is to get back in shape. You are considering various ways of doing this: you can sign up for a gym membership, walk to work, take the stairs instead of the elevator, or watch your diet. How would you evaluate these options and choose an optimal one?
Do a cost-benefit analysis to compare the alternatives.
The period from 2007 to 2009 was a time of economic contraction that came to be known as the "Great Recession." During periods of recession, most firms experience a decline in demand for their product, as well as a decline in the product's equilibrium price. All other things being equal, macroeconomic theory predicts that the wage of most workers should decline in recessionary periods. However, this was not the case in the Great Recession, or during many other economic downturns throughout recent history. Based on the discussion in the chapter, explain why this might be so, and what the implications are for unemployment.
During downturns workers are resistant to the lowering of wages and firms try to avoid doing so. This downward wage rigidity keeps the quantity of labor supplied greater than demand, causing unemployment.
Your client becomes critical of your "sloppy" technique of using a model that does not include all factors. What is the most appropriate reply to this criticism?
Economic models are meant to be approximations that predict what happens in most circumstances.
The EBE also reports evidence from an extensive study that included hundreds of U.S. labor market regions from 1990-2007. The findings tend to confirm the model of labor markets depicted in Exhibit 9.9. Match each finding from the study to the relevant labor market feature. You may need more than one! Communities with high exposure to Chinese imports experienced sharper declines in manufacturing employment than low-exposure communities. (Check all that apply.)
Leftward shift in labor demand.
Barter is a method of exchange whereby goods or services are traded directly for other goods or services without the use of money or any other medium of exchange. Suppose you need to get your house painted. You register with a barter Web site and want to offer your car cleaning services to someone who will paint your house in return. What are the problems you are likely to encounter? (Check all that apply.)
It might be difficult to agree on how many car washes is equivalent to painting a house. It may take a lot of time to negotiate and finally settle on a deal that you both find fair. You might find it difficult to find someone who needs you to wash his car and is willing to paint your house in return.

Banks that practice narrow banking match the maturity of their investments with the term of the deposits that they collect from the public. In other words, narrow banks take short-maturity deposits and invest in assets that carry a low level of risk and are also of short-term maturity, like short-term government debt. Suppose that all FDIC-insured banks decide to adopt narrow banking. How would narrow banking reduce the level of risk in the banking system?
It would reduce risk in the banking system by reducing the likelihood of bank runs and liquidity problems for banks.

Yap is a small island in the Pacific Ocean with a total land area of 39 square miles. In the 1900s, there were only three commodities that were traded on this isolated island—fish, coconuts, and sea cucumber. However, the monetary system in Yap was highly sophisticated. The currency that was used on Yap was called "Fei." Fei were large wheels of stone with a hole in the center. These stone wheels were not quarried in Yap but were brought to the island from elsewhere. The value of each wheel as currency depended on its size, which ranged from 1 foot in diameter to 12 feet. Each time a transaction had to be settled in Fei, the ownership of each stone wheel was transferred to the seller, even if the wheel was not physically moved to the seller's house. What functions of money do Fei satisfy? (Check all that apply.)
Medium of exchange. Store of value. Unit of account.
Traditional currencies are controlled by central banks. What is a potential problem of restricting the creation of bitcoins to a total of 21 million bitcoins?
Monetary authorities cannot undertake expansionary monetary policy to stimulate the economy during recessions.
Imagine that the chairperson of the Federal Reserve announced that, as of the following day, all currency in circulation in the United States would be worth 10 times its face denomination. For example, a $10 bill would be worth $100; a $100 bill would be worth $1,000, etc. Furthermore, the balance in all checking and savings accounts is to be multiplied by 10 as will the balance of all outstanding debts. So, if you have $500 in your checking account, as of the following day, your balance would be $5,000, etc. Would you actually be 10 times better off on the day the announcement took effect?
No, because all prices would increase by a factor of 10 as well, keeping the real value of your money constant.
Almost every day, many people sign their names to little pieces of paper called checks, which are then accepted in exchange for goods and services. Do these checks constitute money?
No, because checks simply represent a means of access to money, not money itself.
Banks fail when they invest in long-term assets that subsequently fall in price. What are the two views on why asset prices fluctuate so much that they lead to financial crises and bank failures?
One view holds that asset prices are rationally based on fluctuating fundamentals, while the other asserts that psychological factors and biases play a significant role.
Economics, anthropology, psychology, sociology, and political science all study human behavior. Economics differs from these other social sciences because it also addresses these three key concepts: _________.
Optimization, equilibrium, and empiricism.
What are some factors that explain why people save for the future? (Check all that apply.)

People spent time exchanging money multiple times per day. Businesses were forced to adjust prices several times per day. Price controls were applied.
Suppose that Sally J. Society recently lost her job as an underwater welder. In looking for a new job, she discovers that the only available jobs are for economists and that there are no openings for underwater welders because the trade is now obsolete. If Sally J. Society decides to return to school to earn an Economics degree, what is the best classification of her unemployment status?
Structurally unemployed

The higher maintenance bill associated with fixing these more complex signals when they break down. The value of the pedestrians' lives saved by having the timers to assist in crossing the street.
What is stockholders' equity?
The difference between a bank's total assets and total liabilities.
Everything else remaining unchanged, what is likely to happen to the equilibrium real interest rate and quantity of credit if the credit supply curve shifts to the right?
The equilibrium rate of interest will decrease and the quantity of credit will increase.
What were some of the benefits? (Check all that apply.)
The government gained the seignorage.
The 1970s saw a period of high inflation in many industrialized countries including the United States. Due to the increase in the rate of inflation, lenders, including credit card companies, revised their nominal interest rates upward. How is the rate of inflation related to the nominal interest rate that credit card companies charge, and why would lenders need to increase the nominal interest rate when the inflation rate increases?
The nominal rate of interest is the real rate of interest plus the rate of inflation; lenders need to raise the nominal rate when inflation increases to maintain their desired real return.
Who bears the risk that a bank faces when stockholders' equity is greater than zero?
The bank's stockholders.
Some barter Web sites allow the use of "barter dollars." The registration fee that you pay to a barter Web site gets converted into barter dollars that can be exchanged with other users to buy goods and services. Would the use of barter dollars resolve the problems you identified above?
Yes, because you could both pay and be paid in "barter dollars."
Excluding cases where banks had accumulated a lot of non-deposit liabilities that are not covered by FDIC insurance, would analysts generally agree that deposit insurance has been successful in preventing bank runs?
Yes, since bank runs and bank failures have been relatively rare since the advent of deposit insurance.
Are the predictions of the quantity theory of money borne out by historical data?
Yes, the long-run data show a one-for-one growth rate of money supply and inflation.
The factors that would shift the demand curve for reserves include ____________. (Check all that apply.)

The inflationary expectation model that states inflationary expectations are determined by the level of inflation in the recent past is called ▼ rational expectations adaptive expectations short-run expectations . The inflationary expectation model that assumes people have highly sophisticated beliefs that incorporate all of the available information is called ▼ adaptive expectations long-run expectations rational expectations. Adaptive expectations are ▼ forward-looking irrational backward-looking .

Optimizing economic agents use the real interest rate when thinking about the economic costs and returns of a loan. Suppose the average rate paid by banks on savings accounts is 0.25% at a time when inflation is around 1.61.6%. For the average saver, the real rate of interest on his or her savings is −1.35%. (Round your response to two decimal places and use a minus sign if necessary.) If banks expect that the rate of inflation in the coming year will be 4.6% and they want a real return of 6% on a certain category of loans, then the nominal rate they should charge borrowers on those loans is 10.6%.

In macroeconomics, a "leading indicator" is defined as a measurable economic variable that changes prior to when the economy as a whole starts to follow a given trend. Conversely, a "lagging indicator" is a measurable variable that only changes in the latter phaseslong dash—or even afterlong dash—an overall trend is evident in the economy. The following chart shows the evolution of the U.S. unemployment rate from January 1948 to January 2014 (monthly data). Note that the shaded bars are recessions and that the unemployment rate increases during recessions. The U.S. Unemployment Rate from 1948 to 2014
Lagging, since in every recession the unemployment rate did not peak until very late into the recession, or in some cases, after the recession.
Over the last 50 years, credit cards have become an increasingly popular way for people to purchase goods and services. Are credit cards money?
No, because you credit cards are not assets.

Sometimes new technology in production reduces the time that a worker takes to complete a task. Technological innovations can also completely replace a factory worker. Does this mean that technological progress will lead to large-scale unemployment?
No, some sectors may experience unemployment as a result of the innovations but overall productivity and incomes will increase, leading to more employment opportunities.
Which of the following is an example of what economists refer to as job search?
People that engage in the job hunt by sending out resumes. An individual that engages in the job hunt by determining who is hiring and how much they pay. A person who applies for a high-paying job but does not qualify, so she begins searching for an appropriate position.

The following table shows the cost of producing dollar notes of various denominations. As you can see in the table, it costs only 12.7 cents to produce a $100 bill. Suppose the government decided that it will print new notes to fund its fiscal deficit as well as all its ongoing expenditure. What would be the effects of such a policy?
Printing paper money has a small direct cost and so gives the government money to spend.
Identify a possible problem with this policy.
Printing too much money may lead to a high rate of inflation, reducing the amount of goods and services that the government can purchase with the newly printed notes.
Which of the following equations is correct?
Real interest rate = Nominal interest rate minus− Inflation rate

Does the behavior of the unemployment rate illustrate the principle of co-movement discussed in the chapter?
Yes, because when real GDP declines, unemployment increases.
Excluding cases where banks had accumulated a lot of non-deposit liabilities that are not covered by FDIC insurance, would analysts generally agree that deposit insurance has been successful in preventing bank runs?
Yes, since bank runs and bank failures have been relatively rare since the advent of deposit insurance.
Comparing a set of feasible alternatives and picking the best one is an optimization process called _________.
cost-benefit analysis.
An open market operation is ____________.
an exchange between a private bank and the Federal Reserve where the Fed buys or sells government bonds to private banks.
If you have studied microeconomics, you may recall a concept called "moral hazard." Moral hazard occurs when an economic agent is incentivized to take risks because some (or all) of the losses that might result will be borne by other economic agents. How might federal deposit insurance, as administered by the FDIC, lead to moral hazard?
All of the above are plausible.
What is the shadow banking system?
All of the above describe the shadow banking system.
Based on what you learned about banking in the chapter, explain why you think that the crisis prompted banks to dramatically expand the amount of excess reserves they held.
All of the above.
Free riding occurs when people's private benefits are out of sync with the public interest . Which of the following is subject to the free-rider problem?
All of the above.
In which of the following areas will taking an economics course help benefit you throughout your life?
All of the above.
Bitcoins are defined as a "peer-to-peer decentralized digital currency." The supply of bitcoins is not controlled by the government or any other central agency. The value of each bitcoin is determined on the basis of supply and demand and is defined in terms of dollars. New bitcoins can be generated through a process called "mining." However, new bitcoins will not be created once there are a total of 21 million bitcoins in existence. Some commentators feel that bitcoins can eventually replace most of the major currencies in the world. What are some of the issues with bitcoins replacing major currencies? (Check all that apply.)
Fiat money is generally worthless without a government decree that it is legal tender. The value of a bitcoin is highly volatile and so people that hold them may lose money. Bitcoin deposits are not insured by the government.
As the Choice and Consequence box on "Too Big to Fail" notes, bank regulators worry about the prospect of the failure of large financial institutions, dubbed "systemically important financial institutions" (SIFIs). How would the failure of a systemically important financial institution (SIFI) affect the economy?
Financial intermediation would likely be impaired, with negative consequences for the economy's performance.
The sharpest one-day percentage decline in the Dow Jones Industrial Average (DJIA) took place on October 19, 1987. The DJIA fell 23 percent on this one day. Foreign exchange markets and other asset markets also exhibit large fluctuations on a daily basis. Eugene F. Fama, Robert J. Shiller, and Lars Peter Hansen shared the Nobel Prize in Economic Sciences in 2013 for their work on the "empirical analysis of asset prices." Based on the information given in this chapter, which of the following factors could explain why asset prices fluctuate? (Check all that apply.)
Fluctuations reflect the rational appraisals by investors of new information relevant to asset profitability. There are pychological factors and biases that can produce excessive reactions to booms and busts.
The process of critical thinking often involves formal and informal writing. Why do critical thinkers use both types of writing?
Formal writing is used to communicate the results of one's critical thinking and to persuade others that one is right. Informal writing is primarily intended for oneselft or others with whom one is working, and is used to facilitate the critical thinking process itself.
Suppose John Q. Worker is currently unemployed. Each day, John Q. Worker spends the entire day searching available job openings for an appropriate position given his set of skills, abilities, and interests. If someone asks John Q. what he does for work, he tells them that he is currently "in-between jobs." Which of the following best classifies John Q.'s unemployment status?
Frictionally unemployed
What were some of the adaptations that the country adopted to cope with the situation? (Check all that apply.)
Redenominations of the Zimbabwean dollar. The use of foreign currencies for transactions. The use of the black market for many transactions.
The study found no decline in manufacturing wages. (Check all that apply.)
Rigid or not completely flexible wages.
The chapter discusses different models of how people form their expectations regarding inflation. Consider the following two investors, who are trying to forecast what inflation will be for next year. Sean reasons as follows: "Inflation was 2.5 percent last year. Therefore, I think it is likely to be 2.5 percent this year." Carlos, on the other hand, thinks this way: "The economy has recovered from recession sufficiently that inflationary pressures are likely to build. Likewise, a weaker dollar means that imports are going to be more expensive. I don't think the Fed will risk slowing the recovery and raising unemployment by raising interest rates to fight inflation. So, in light of all these factors, I expect inflation to increase to 5 percent next year." How would you best describe how each investor is forming his expectations of inflation? Sean is forming his forecast based on the adaptive expectations model of inflation and Carlos is forming his forecast based on the rational expectations model of inflation. What are possible criticisms of the way each investor is forming his expectations? Economists might argue that
Sean is not maximally rational, and Carlos can not be as good at understanding how the economy works as he thinks he is.
The opportunity cost of an activity is a measure of what is given up when you do that activity. Let's say that you are trying to decide what to do on Friday at 11 a.m. You rank your possible options from the one you value the most to the one that you value the least in the following order: going to class, sleeping in late, going to work early, getting lunch, going to the gym to exercise, and watching television. If you decide to go to class, then what do we know about the opportunity cost of your decision?
The opportunity cost would be sleeping in late, since it was your next-best option.
In response to high unemployment, the Spanish government enacted a series of labor market reforms in 2012. Among other measures, the government reduced severance pay and the influence of unions in setting wages and hours of work. What could be the rationale behind using these measures to boost employment?
The rationale behind these measures was to lower unemployment by addressing the wage rigidity caused by unions and firms' unwillingness to hire new employees because of severance pay obligations.
In an economy, the working-age population is 200 million. Of this total, 160 million workers are employed. 6 million workers are unemployed. 28 million workers are not available for work (homemakers, full-time students, etc.). 4 million workers are available for work but are discouraged and thus are not seeking work. 2 million workers are available for work but are not currently seeking work due to transportation or childcare problems.
The unemployment rate in this economy is 3.63.6%. (Round your answer to one decimal place.)
What role do personal (or professional) values play in thinking critically about macroeconomic issues?
Their role depends on the nature of the macroeconomic issue being investigated. However, one should be aware of any values that one holds that might be relevant to the macroeconomic issue.

There has been a steady increase in both the size of the adult population and the labor force participation rate between 2006 and 2016.
Which of the following are possible benefits of inflation? (Check all that apply.)
There may be a reduction in real wages. Revenue is generated to the government when it prints money. There may be a reduction in the real interest rate.
According to the BBC, inflation in the country of Zimbabwe reached an annualized rate of 231,000,000 percent in October of 2008. Prices got so high that in January of 2009, the country's central banklong dash—the Reserve Bank of Zimbabwelong dash— introduced a $100 trillion bill. Use the following link to read the summary of Zimbabwe's experience with hyperinflation in Wikipedia: http://en.wikipedia.org/wiki/Hyperinflation_in_Zimbabwe). What was the root cause of hyperinflation in Zimbabwe?
There was an increase in the money supply in excess of the growth rate of real GDP.
What does it mean to say that an economic fluctuation involves the co-movement of many aggregate macroeconomic variables?
These variables grow or contract together during booms and recessions.
What are the costs associated with inflation? (Check all that apply.)
Uncertainty about the aggregate price level, which can distort prices and make planning difficult. Logistical costs related to the need to frequently change prices. Unproductive policies such as price controls, which may be due to voter dissatisfaction.

Which of the following is more susceptible to the free-rider problem: state parks or city−wide pest control?
Use of city−wide pest control is more susceptible since even those who don't pay taxes still benefit, while state parks can charge for admission, so that everyone who goes pays their share.
Which of the following is more susceptible to the free-rider problem: fishing in public lakes or street lights?
Use of street lights is more susceptible since even those who don't pay taxes still benefit, while fishing in public lakes can charge for a fishing license, so that everyone who goes pays their share.
The study found a significant decline in wages of non-manufacturing workers in high exposure areas. (Check all that apply.)
Wage rigidity may not extend to new jobs outside the impacted industry. Leftward shift in labor demand.
