The labour market Flashcards
Derived demand
when demand for labour is driven by demand for goods
marginal productivity theory
the demand for any factor of production depeneds on MRP
MRPL
Marginal revenue product of labour the extra revenue gained for employing one more worker
MRPL equation
MPPL(marginal physical product of labour) times by MR (Marginal revenue)
Marginal cost of labour
the cost of hiring one additional worker
MPPL and MRPL curve
Slope downwards because of law of dimishing returns which means as each worker is employed output falls
Cause of shifts in the demand curve of labour(MRPL Curve)
Changes in price- if price falls it will decrease firms demand for labour shifting MRPL to the left
changes in labour productivity-if theres new training and technology it will increase productivity shifting MRPL to the right
Changes to the cost of labour-if costs increase it will decrease demand and shift MRPL to the right
Elasticity of demand for labour
The change in demand when wage level changes
elasticity of demand for labour equation
changes in quantity demanded by change in wage rate
Factors influencing elasticity of demand for labour
the ability to replace labour it will be more elastic if they can replace labour
if labour can be subsituted it can be elastic
the proportion of wage in firms costs if theres a large proportion then it will be elastic
the PED of the product the more elastic it is then more elastic labour is
Individual labour supply
The total number of hours a person is willing to work at a given wage rate
Occupational labour supply
The number of workers willing to work in that occupation at a given wage rate
Occupational labour supply graph
As wage rate increases for an occupation quantity of labour increases
the supply curve slopes upwards
Subsitution effect
as wages rise the opportunity cost of leisure time increases which means workers have incentive to subsitute leisure time with work
Individual supply curve
if theres a higher wage rate workers work fewer hours
quantity of labour decreases as wages rise
Income effect
people choose to work less even through wage rate increases
Monetary benefits
the weflare a worker gains from the wage they recieve
