Q

In labour market equilibrium, are all people employed and all vacancies filled? Why/why not?

Q

What happens when real wage increases?

A

MPL decreases, lower than new real wage, firms reduce demand for labor to where the MPL increases to the new real wage

Q

True or false: real wages are high and amount of capital vs workers is large in poor countries

A

Fales: This is true for rich countries, the opposite is true for poor countries
Poor countries have low real wages and more people working than machines because when real wages are low, it is cheaper to use people for labour than buying machines.
When real wages are high, more cost effective to buy machines instead of pay more people

Q

What does the labour demand curve represent/show?

Q

When firms are demanding less labour, real wages go:

A

down

24
Q

When firms are demanding more labour, real wages go:

A

up

25
Q

Real wage is the relative price of ___ in terms of ___ and the price of ___ in terms of ____

A

consumption ; leisure ; leisure ; consumption

26
Q

Are consumption and leisure considered goods?

A

Yes, increases utility

27
Q

What is the substitution affect from higher real wage?

A

Choose less of relatively higher price (leisure) - reduce leisure, work more
Choose more of relatively lower price (consumption) - increase consumption

28
Q

What is the income effect from higher real wage?

A

Working same number of hours = more consumption so prefer more leisure, work less

29
Q

When is the substitution effect stronger than the income effect from real wage increase?

A

When increased wage is temporary

30
Q

When is income effect stronger than the substitution effect from real wage increase?

A

When wage increase is permanent

31
Q

What is the main effect of a change in the real wage on the labour supply curve?

A

Changes in hours and number of workers

32
Q

When real wage goes up, labour supply goes:

A

Up

33
Q

What does the labour supply curve show?

A

Shows real wage and labour supply relationship / how the change in real wage affects the number of workers/hours

34
Q

What shifts the labour supply curve?

A

Wealth and tax rates

35
Q

What causes the labour supply curve to shift left?

A

Increased wealth

36
Q

How does a lower tax rate affect the labor supply for jobs where hours can be chosen? Does the marginal or average tax rate apply?

A

Has both income and substitution effects, lower tax rate = higher after tax income and consumption, but effect on labour supply depends on effects of income and substitution effects; based on marginal tax rate - worker decides whether to give up hour of leisure for hour of work

37
Q

How does a lower tax rate affect the labor supply for jobs where hours cannot be chosen? Does the marginal or average tax rate apply?

A

Only substitution affect; based on average tax rate - worker can only decide whether to work or not, choice depends on average tax, because worker decides to give up 2000 hours of leisure for work income net of average tax rate

38
Q

Where does the labour market equilibrium occur?

A

When real wage makes both supply and demand equal

39
Q

When there is excess supply of labour, what happens to real wage? What happens when there is excess demand?

A

Excess supply = real wage falls
Excess demand = real wage increases

40
Q

If real wage is below equilibrium, is there a labour or job shortage?

A

Labour shortage

41
Q

If real wage is above equilibrium, is there a labour or job shortage?

A

Job shortage

42
Q

If real wage is below equilibrium, what must happen to get back to equilibrium?

A

Wages must increase to attract workers, to increase real wage

43
Q

If real wage is above equilibrium, what must happen to get back to equilibrium?

A

Workers must accept lower wages, to decrease real wage

44
Q

Is supply or demand greater when there is a labour shortage?

A

Demand is greater than supply

45
Q

Is supply or demand greater when there is a job shortage?

A

Supply is greater than demand

46
Q

If labour demand shifts right, what happens to demand?

A

Excess demand is left at the old wage, real wage increases, work hours and employment increases

47
Q

If labour supply shift right, what happens to employment and wages?

A

Increase employment, lower real wage, lower wealth, less leisure to work more instead, shift supply curve right

48
Q

How is unemployment and employment measured?

A

Survey with three categories: employed, unemployed, and not in the labour force

49
Q

What is the labour force participation rate? What is it’s equation?

A

Proportion of adults working or looking for work
= labour force/adult population

50
Q

What is the employment rate and it’s equation? What is the unemployment rate and it’s equation

A

Proportion of adults employed
= Employed/adult population

Proportion of adults unemployed in the labour force
= Unemployed/labour force

51
Q

Labour force equation

A

employed + unemployed

52
Q

What does the unemployment rate not include?

A

People moving from “out of labour force” to unemployed (looking)
People moving from unemployment to not in labour force
Seasonal variation

53
Q

Did the pandemic increase unemployment? What did the pandemic do to participation rate and the employment rate?

A

The pandemic raised unemployment from the lowest it had been since 1976, to the highest
Reduced the participation rate and employment rates to lowest since 1976

54
Q

The derivative of the production function with respect to labour is equal to:

A

the marginal product of labour (W/P = MPL)

55
Q

Adult population vs labour force

A

adult population = labour force and out of labour force
labour force = employed and unemployed
