6.8 million, what is the rate of unemployment?
17. What are two criticisms of the unemployment rate? How do these criticisms relate to the overstating or
understating of the unemployment rate?
18. Explain the differences among the frictional, structural, and cyclical forms of unemployment.
Frictional unemployment is the unavoidable and even positive type of unemployment characterized by
people who are searching for new jobs or waiting to take jobs in the near future. Structural unemployment
is unemployment due to changes occurring over time in the structure of consumer demand or in technology
which result in some skills being in less demand or even becoming obsolete. It may also be due to a
change in the geographic distribution of job opportunities. Cyclical unemployment is the unemployment
caused by the recession phase of the business cycle. Economists place special emphasis on this type of
unemployment because they believe that economic policy can reduce cyclical fluctuations in the economy
and therefore can reduce cyclical unemployment.
19. Name the type of unemployment occurring in each of the causes below and explain your answer.
(a) Frank recently lost his job as the computer manufacturing company he works for recently downsized
after poor sales and poor performance of the economy during the last year.
(b) Julie just recently graduated from college and is spending the summer traveling before she begins a job
with a consulting firm in the fall.
(c) Tom recently lost his job as the steel manufacturing firm he worked for moved their plant overseas.
The other steel plants in the nation have been also been following this trend.
(d) Susan recently left her marketing job at a local bank because she found that finance interests her more.
She is currently looking for a job as a financial consultant.
20. (Consider This) Are wages more flexible upward or downward? Explain what effect this has during a time
of expansion and a time of recession.
Wages are flexible upward, workers are happy to accept an increase in their wage rate. However, workers

as economists currently define it.

(a) To get the rate of inflation, subtract last year’s index from this year’s index (108 − 100 for year 2);
divide this result (8) by last year’s index (100) to get 0.08; multiply by 100 to change to percent (8%).
(b) The rule of 70 says divide the rate of increase, 8, into 70 and this gives the approximate time for prices
to double (approx. 8.8 years). Note that in years 3 and 4, the index changes by 12 points each year, but
the inflation rate will differ because the reference index base has changed from 108 to 120.
30. Inflation is frequently described as “too much money chasing too few goods.” Is this an acceptable
definition?
31. What is “demand-pull” inflation?

37. Assume that nominal income is $35,000 and the price index is 1.20 in year 1. In year 2, nominal income
rises to $38,000 and the price index rises to 1.25. What was the percentage change in real income from

percentage change in real income and the absolute change in real income using the approximation formula

48. What are the effects of cost-push inflation on real output?
49. Some economists believe that creeping inflation cannot be accepted because a gradual increase in prices
leads to an ever-rising rate of inflation. Other economists argue that in order to achieve economic growth,
some moderate price increases are necessary. Contrast and evaluate these two points of view.
The argument in the first case is that even low levels of inflation impose a cost on the economy that reduces
