The document outlines key concepts and exercises related to inflation and unemployment in economics, including definitions, calculations of price indices, and the impact of inflation on various economic groups. It also delves into the natural unemployment rate, labor force participation, and the role of the Federal Reserve in controlling the money supply through various tools. Additionally, it addresses the implications of economic theories, particularly those of John Maynard Keynes, regarding wage flexibility and government intervention in the economy.

ECN211 Chapter 8 Worksheet – Unemployment
Section 8.1– How the Unemployment Rate is Defined and
Computed
1. Give examples of those individuals in the population who are
not interested in working, and thus are considered out of the
labor force.
2. Who is considered part of the labor force?

February 2015 (or the date presented in your text)? How does
that compare to the current unemployment rate?
4. Give two examples of those who are the hidden unemployed.

rate. Consider Table 8.1 What was the labor force participation
rate in February 2015 (or the date presented in your text)? How
does that compare to the current labor force participation rate i?

labor force participation rate?

time?

and by race and ethnicity (Figure 8.4).
11. Analyze the reasons for reported unemployment and the
length of time unemployed (Tables 8.2 and 8.3).
12. Describe trends in US unemployment relative to other high
income countries. Why is it more difficult to compare
unemployment rates between rich countries and developing
(poorer) countries?
Section 8.3– What Causes Changes in Unemployment over the
Short Run
13. Define cyclical unemployment, and describe how the
presence of it challenges the presumption of efficient labor
markets (i.e., wages return to equilibrium quickly and all
workers supplied are demanded, leaving a 0% unemployment
rate).

8. 14. Why might wages be sticky downwards? Describe the
various arguments for why this may be:
a. Implicit contract
b. Efficiency wage theory
c. Adverse selection of wage cuts argument
d. Insider-outsider model
e. Relative wage coordination argument
15. Graph the impact of a labor market experiencing a surplus
and sticky wages downwards. Should we expect wages to fall
and thus more employers to hire?
Section 8.4– What Causes Changes in Unemployment over the
Long Run
16. Describe what is meant by the natural unemployment rate.
17. Contrast frictional unemployment from structural
unemployment, and how together they determine the natural
unemployment rate.
18. Relate the natural unemployment rate with the idea of
potential real GDP.
19. How could changes in labor productivity levels, and
corresponding increases in wages, lead to unemployment? What
will need to happen to productivity to solve the labor surplus

9. (Figure 8.8)?
20. How can public policy impact the natural rate of
unemployment?
21. The natural rate of unemployment is argued to be lower in
the 21st Century than in previous decades. Give 3 reasons to
account for this.
22. Compare the US natural rate of unemployment to many
countries in Europe. Why might countries differ in their natural
rates of unemployment?
