Q

what does ‘Uncovered sector’ absorbs displaced unskilled workers mean (possible reasons for employment not changing as much as theory suggests)

A

might have affected workers in one sector where firms employ unskilled workers its possible at aggregate economy level the workers who are displaced from one sector to be absorbed in other sectors (find work where minimum wage doesn’t apply)

Q

explain wage (=MC) = marginal revenue product (MRP) of labour (assumptions for standard model)

A

the marginal cost of getting another unit of labour is just the wage as all workers are paid the same and there is an infinite number of workers willing to work for the wage

36
Q

what are some examples of labour market frictions

A

imperfect information about job opportunities,
switching costs,
preferences for particular jobs (proximity flexibility)

37
Q

what does upward sloping labour supply curve mean

A

if a firm wants to employ more workers they have to offer more in order to overcome switching costs or preference costs

38
Q

what does the labour diagram look like for a wage setting firm

A

look on first lecture notes ever for micro

39
Q

why is MC to the left of labour supply for the wage setting firm

A

if employ 10 workers might have to offer £9 an hour and 11 workers £10 an hour so the marginal cost is greater than the wage offered to the 11th person (so to the left of the wage curve)

40
Q

where is equilibrium for the wage setting firm

A

where MC = MRP

41
Q

does a minimum wage affect the MC curve

A

yes, see back of first page of lectures

42
Q

how does minimum wage affect labour diagram

A

back of first page lecture notes

43
Q

up to a point a minimum wage _____ lead to lower employment

A

doesn’t (think about diagrams (on first page of lecture notes)

44
Q

what explains the labour discipline model

A

employment contracts are incomplete, effort responds to wage increases

45
Q

draw curves that represent labour discipline model

A

look at back of first page of lecture notes

46
Q

why does increase in wage affect effort for the labour discipline model

A

wages up so cost of losing job greater so they will put more effort in

47
Q

is firms having to pay more always a bad thing

A

no, firms reduce profit but some offset by increase in effort provided by the workers

48
Q

who are the losers from minimum wage legislation

A

firms have reduced profits when they use a lot of low skilled workers,
increased prices passed on due to higher costs for firms

49
Q

what does progressive mean

A

helps people from the poorer end of the income distribution

50
Q

what does regressive mean

A

primarily benefits people in rich part of income distribution

51
Q

why is it not as simple as wages increase due to minimum wage

A

other income needs to be taken into account not just labour,

possible increase in taxes paid (offset reduction of benefits received)

52
Q

whats an issue with minimum wage

A

doesn’t take into account household measures, might be poor worker within wealthy household so not representative

53
Q

what are some main reasons for minimum wage not being well-targeted on poor households *

A

many of the poorest don’t work,
many low paid individuals don’t live in poor households,
low paid low income households receive in work tax credits that are withdrawn if their incomes rise

54
Q

when testing evidence what do you need to do

A

internal validity, ‘ronseal test’ does the study identify the causal effect of the MW on employment,
external validity, can we apply results of study to other settings

55
Q

what does missing counterfactual mean

A

unobserved and unobservable (can’t see what it would have been like if not introduced)

56
Q

how does card and kreuger basically work

A

exploit state differences in minimum wage legislation so look at differences between New Jersey who had an increase in minimum wage and Pennsylvania who had no change in minimum wage

57
Q

why did they use fast food restaurants for card and kreuger

A

major employers of low-wage workers,
likely to comply with legislation,
homogenous (one burger king is like another

58
Q

what did they collect for card and kreuger

A

410 restaurants,

information on wages and number of people employed in each restaurant

59
Q

equation for DiD

A

(treatment group after - treatment before) - (control after - control before)

60
Q

where can you test for common trends

A

in the pre-period

61
Q

if something is statistically significant is that enough

A

no sometimes things are statistically significant but really small so doesn’t really justify

62
Q

what did card and kreuger find

A

found nothing that gave support to the predictions of the standard model

63
Q

has minimum wage decreased employment in the uk

A

minimum wage has largely been introduced without decreasing employment in the uk

64
Q

part time ____ are most affected negatively in terms of employment due to minimum wage in the uk

A

female

65
Q

talk about Mark Stewart (2004) uk minimum wage **

A

focused on introduction of minimum wage, showed that nmw increased wages but found no significant employment effects

66
Q

for the uk studies who was the treatment and control group

A

treatment those paid < nmw before reform,

control those paid just above nmw (+10%) before

67
Q

focus of interest for uk paper

A

what is the probability that treated workers stayed in employment after introduction/increase in nmw

68
Q

what did they find about nmw for treatment and control for uk

A

over whole nmw period, wages grew faster among the treatment group than the control group

69
Q

does the low pay commission take into account possible employment effects

A

yes they take into account possible negative effects on employment

70
Q

what is employment retention

A

ability of an organisation to retain its employees

71
Q

do low paid workers have a low or high employment retention

A

low

72
Q

what are the Hicks-Marshall laws of derived demand *

A

degree of substitutability with other factors (capital),
elasticity of demand for the final product (capital),
low-wage-labour share in total costs,
elasticity of demand for the final product

73
Q

what do you need to do

A

go over all different classes including min wage Hicks-marshall laws of derived demand

74
Q

what is the monopsony model of labour markets (imperfect competition) *

A

classic monopsony case - single employer with no competitors,
there are labour market frictions,
workers cannot move costlessly, firms have some market power

75
Q

what are the labour market frictions in the classic monopsony case with single employer no competitors

A

imperfect information about job opportunities,
switching costs,
preferences for particular jobs (proximity, flexibility),
workers cannot move costlessly firms have some market power

76
Q

when is the classic monopsony case unrealistic

A

unrealistic for many of the markets where MW bites - fast food, care homes, hairdressers etc (check 46/71)

77
Q

for labour discipline model what does the isocost line represent

A

isocost = constant cost per unit of effort

78
Q

what is a potential response to minimum wage from labour discipline model

A

workers respond to increase in wages by increasing their effort, shift in labour demand curve as labour is now more productive

79
Q

things to take into account for overall employment discussion

A

assumptions may be more or less relevant depending on sector, or depending on time-frame (short vs long),
longer term effects,
dynamic model that allows entry/exit of firms putty clay model

80
Q

what is the key feature of the putty-clay model

A

that potential entrants are able to pick a capital-labour ratio that is well-suited to the minimum wage while incumbents are not

81
Q

what is the putty clay model

A

dynamic model that allows for entry/exit of firms,
firms choose technology (capital/labour mix), costly to adjust,
in the short-run, little substitution (possible scale?),
in the longer term they are forced out by new entrants with a different (cheaper) technology

82
Q

what is a putty-putty model

A

costs are not fixed in a company,
intro of min wage firms just replace workers with capital,
increase in relative cost of labour –> proportionate fall in demand

83
Q

how does workers moving from the covered sector to the uncovered sector work when minimum wage introduced

A

intro of MW causes reduction of employment in covered sector,
displaced workers move from covered sector to uncovered sector

84
Q

what does the workers moving from covered sector to uncovered sector when minimum wage depend on

A

assume that workers can move between sectors,
depends on extent to which uncovered sector can absorb displaced workers from covered sector,
size of two sectors, mobility of workers between sectors, elasticity of demand in uncovered sector

85
Q

what does draca (2011) show

A

that profits in low-wage firms were negatively affected (compared to high-wage firms),
magnitude constant with full cost pass-through

86
Q

what does wadsworth (2010) show

A

that prices in low-wage industries in the UK (hospitality, cleaning etc) rose by more than RPI,
who consumes goods and services produced by low-wage workers

87
Q

what is a clay-clay model

A

firm’s production technologies are fixed even in the long run, increase in relative cost of labour –> no change in demand

88
Q

what is Hicks-Marshall laws of derived demand related to factor of substitution

A

elasticity of factor substitution is a key factor in determining the employment response to MW,
how do firms adjust factor inputs in response to changes in relative factor prices

89
Q

what is the uncovered sector

A

sectors where the minimum wage does not apply,
exempt sectors,
informal economy
