INDIVIDUAL BACKWARD BENDING SUPPLY CURVE FOR LABOUR
If W* is £10 per hour x 40 hours per week, monthly earnings are £400 If wage is doubled to £20 hours per hour one would work 20 hours to achieve their target level of income This is an individual curve so the shape varies depending on the strengths of the two effects From the diagram we can see that initially as the real wage offered increases the individual is willing to work more hours However once the target level of income (point A) has been achieved any further in the real wage will be met by less hours being worked This is due to the fact that after the target level of income has been achieved, the individual increasingly sees leisure as a luxury good If the real wage is doubled the individual would be willing to work half the time In order to fully appreciate the relationship we need to first appreciate the relationship between - the substitution effect and the concept on opportunity cost and the income effect and the target level of income
SUBSTITUTION EFFECT As real wage offered increases the opportunity cost of choosing leisure over work gets greater As such people will increasingly choose to work more hours at the expense of leisure Always POSITIVE INCOME EFFECT Initially as the wage offered is increased this acts as an incentive for the individual to work more hours as their ability to achieve their target level of income has increased There comes a point however where the income effect becomes negative but its insufficient to outweigh the positive substitution effect This occurs as an individuals income begins to approach their target level of income Once this level has been achieved the negative income effect outweighs the positive substitution effect and the supply curve goes backwards (once this level is achieved more value is placed on leisure and hours worked fall) If the wage doubled the individual would work half of the time whilst maintaining their target level of income
THE SUPPLY OF LABOUR FOR AN ECONOMYThe supply of labour available to an economy is influenced by the size of the population. However it would be wrong to suggest that the supply of kabour is the same sizeof the populationTHE ACTUAL LABOUR FORCE:- includes individuals who are employed and those individuals actively seeking employmentTHE POTENTIAL LABOUR FORCE:- includes the actual labour force and the economically inactiveTHE PARTICIPATION RATE:- the proportion of the working age population who are economically active and is calculated by using the following formula which is expressed as a percentage
MOVEMENTS ALONG A SUPPLY CURVE FOR LABOUR
At the increase from W to W1 there is an extension along SL, a decrease in W to W2 causes a contraction along SLA change in the real wage will cause a movement along the existing supply curve and that there is indeed a positive relationship between real wage and quantity supplied
SHIFTS IN THE SUPPLY CURVE FOR LABOUR
The real wage offered hasn't changed, however the number of people willing to work has increased; this may be due to the fact that:- A change in the value placed on leisure time, if more value is placed on leisure time than overtime supply to all industries would decrease A change in the working conditions/wage offered in an alternative industry (assuming occupational mobility - explain below diagram)
Artificial limits to an industries labour supply (eg through the introduction of minimum entry requirements or other legal barriers to entry) Increasing the size of the working population. As the supply of the labour increased due to the increase in population one would expect a corresponding increase in the supply of labour Changes in non-pecuniary benefits enjoyed by workers in the industry eg changes in job status/ changes in holiday entitlement PECUNIARY BENEFITS monetary benefits gained from employment eg wages, bonusNON-PECUNIARY BENEFITS non-monetary benefits gained from employment eg perceived job status, job satisfactionNET ADVANTAGES of an occupation include monetary benefits, quasi-pecuniary benefits, and non-monetary advantages and disadvantages of an occupationQUASI-PECUNIARY BENEFITS give workers a financial benefit without increasing wages eg staff discount, company car, private healthcare
