
The major types of unemployment
 Frictional
 Structural
 Cyclical
 Seasonal
7-20
The Major Types
of Unemployment (cont'd)

Frictional Unemployment
 Results
from the fact that workers must
search for appropriate job offers
 This
takes time, so they remain
temporarily unemployed
7-21
The Major Types
of Unemployment (cont'd)

Structural Unemployment
 Results
from a poor match of workers’ abilities
and skills with current requirements of
employers
7-22
The Major Types
of Unemployment (cont'd)

Cyclical Unemployment
 Results
from business fluctuations that occur
when aggregate (total) demand is not at a
level that would result in full employment
 Can
be positive or negative
7-23
The Major Types of Unemployment

Seasonal Unemployment
 Results
from the seasonal pattern of work in
specific industries
 Adjustments
are made to offset the effects of
seasonal unemployment so that meaning
comparisons can be made between different
periods of the year. This adjustment is
needed in order to assess the affects of the
other types of unemployment.
7-24
Full Employment and the Natural Rate
of Unemployment (cont'd)

Full Employment
 An
arbitrary level of unemployment that
corresponds to “normal” friction in the
labor market
7-25
Full Employment and the Natural Rate
of Unemployment (cont'd)

Natural Rate of Unemployment
 The
unemployment rate that is
estimated to prevail in the long-run
macroeconomic equilibrium
 Should
not reflect cyclical unemployment
 When
seasonally adjusted, the natural rate
should include only frictional and structural
unemployment.
7-26
Inflation and Deflation

Inflation
A
sustained increase in the average
of all prices of goods and services in
an economy

Deflation
A
sustained decrease in the average
of all prices of goods and services in
an economy
7-27
Inflation and Deflation (cont'd)

Purchasing Power
 The
value of money for buying goods
and services
 Varies
with prices and income
7-28
Inflation and Deflation (cont'd)

Nominal value
 Price

expressed in today’s dollars
Real value
 Value
expressed in purchasing power,
adjusted for inflation
7-29
Measuring the rate of inflation
Index The cost of today’s market basket
of goods expressed as a percentage of the
cost of the same market basket during a base
year
 Market Basket Representative bundle of
goods and services
 Base Year The point of reference for
comparison of prices in other years
 Price
Cost today of market basket
 100
Price index =
Cost of market basket in base year

statistical measure of a weighted average of
prices of a specified set of goods and services
purchased by wage earners in urban areas


Producer Price Index (PPI)

measure of prices; reflects both
price changes and the public’s market
responses to those price changes

Index
