chapter 30 Flashcards
(32 cards)
In the long run, increases in the labour force are __________ by increases in employment.
more or less matched
In the short run, the unemployment rate _______
because ____________
fluctuates considerably because hanges in the labour force are not exactly matched by
change in employment.
supply side employment trend
On the supply side, the labour force has grown virtually every year since the end of the Second World War.
demand side employment trend
On the demand side, many existing jobs are eliminated every year,
and many new jobs are created.
general employment trend
In most years, enough new jobs are created to offset the number of jobs that have been eliminated and to provide jobs for the growing labour force.
The result is a net increase in employment in most years
during periods of rapid economic growth, the unemployment rate________
usually falls
short run fluctuation
During recessions or periods of slow growth, the unemployment rate _______
usually rises (short run fluctuation)
Over longer periods, unemployment changes more due to _________
structural changes in the labour force
what is a measurement problem
The official data understate the full effects of recessions on unemployment because they do not include:
• discouraged workers
• underemployed workers
two important costs associated with unemployment:
- lost output
- personal costs
cyclical unemployment
• the difference between actual unemployment and the amount that would exist when Y = Y*
what kinds of unemployment still exists when Y=Y*
- frictional
* structural
def. cyclical unemployment
unemployment not due to frictional or
structural factors; it is due to deviations of GDP from Y*.
market clearing theories
real GDP is always equal to Y*.
So the only unemployment is frictional and structural, and the unemployment rate is always equal to the NAIRU.
non-market clearing theories
emphasizes the distinction between the unemployment that exists when real GDP is equal to Y, and unemployment that is due to deviations of real GDP from Y.
market-clearing theories explain fluctuations in employment and real
wages as having one of two causes:
- Changes in technology that affect the marginal product of labour will lead to changes in the demand for labour.
- Changes in the willingness of individuals to work will lead to changes in the supply of labour.
**In both cases, the flexibility of real wages results in a clearing of the labour market.
**Whatever unemployment exists must be caused by frictional or structural causes, the two components of the NAIRU.
what do Market-clearing theories of the labour market assume?
real wages always adjust to clear the labour market
People who are not working are assumed to have voluntarily withdrawn from the labour market.
There is no involuntary unemployment.
non-market clearing wages
When the wage rate does not change enough to equate quantity demanded with quantity supplied, there will be unemployment in slumps and labour shortages in booms.
Why do wages not quickly adjust to eliminate involuntary unemployment?
- Long-Term Employment Relationships
-In labour markets in which long-term relationships are important,
the wage rate does not fluctuate to continuously clear the market. - Economic Climate Versus Economic Weather
- -Variations in real wages usually occur gradually and are determined by the long-term economic “climate”.
- –Changes in the short-term economic “weather”, unless extreme, tend not to cause changes in real wages. - Efficiency Wages
Firms may find it profitable to pay higher-than-marketclearing wages so that workers put forth greater effort. - Union Bargaining
Wages may be more influenced by “insiders” than by “outsiders” —this may keep wages high, even in the face of declining demand.
def. frictional unemployment
s unemployment that results from the
turnover in the labour market as workers move between jobs.
The normal turnover of labour causes frictional unemployment to persist, even if the economy is at potential output
def. structural unemployment
unemployment caused by a mismatch in
skills, industry, or location between available jobs and unemployed workers.
Structural unemployment will increase if there is either an increase in the pace at which the structure of the demand for labour is
changing or a decrease in the pace at which labour is adapting to these changes.
In a sense, structural unemployment is really long-term _______ unemployment
frictional
describe the frictional-structural distinction
Suppose there was an increase in world demand for Canadian-made
car parts and at the same time a decline in world demand for
Canadian-assembled cars.
Labour would move from the car-assembly sector to the car-parts
manufacturing sector
If the reallocation were to occur quickly, we would call the unemployment frictional; if the reallocation were to occur slowly, we
would call the unemployment structural.
In practice, structural and frictional unemployment cannot be separated.
But the two of them, taken together, can be separated from cyclical
unemployment.
describe demographic shifts and how that might affect NAIRU
Greater labour-force participation by groups with high unemployment rates increases the NAIRU.
