If the substitution effect is stronger than the income effect then the labour supply slopes upward. If, beyond a certain wage rate, the income effect is stronger than the substitution effect, then the labour supply curve bends backward. Individual labor supply curves can be aggregated to derive the total labour supply of an economy. [1]
The labour supply curve shows how changes in real wage rates might affect the number of hours worked by employees.. In economics, a backward-bending supply curve of labour, or backward-bending labour supply curve, is a graphical device showing a situation in which as real (inflation-corrected) wages increase beyond a certain level, people will substitute time previously devoted for paid work ...
Supply is often plotted graphically as a supply curve, with the price per unit on the vertical axis and quantity supplied as a function of price on the horizontal axis. This reversal of the usual position of the dependent variable and the independent variable is an unfortunate but standard convention.
Labour demand is a derived demand; that is, hiring labour is not desired for its own sake but rather because it aids in producing output, which contributes to an employer's revenue and hence profits. The demand for an additional amount of labour depends on the Marginal Revenue Product (MRP) and the marginal cost (MC) of the worker.
The 45-degree line represents an aggregate supply curve which embodies the idea that, as long as the economy is operating at less than full employment, anything demanded will be supplied. Aggregate expenditure and aggregate income are measured by dividing the money value of all goods produced in the economy in a given year by a price index.
Part I of the book takes as its starting point a reformulation of the marginal productivity theory of wages as determined by supply and demand in full competitive equilibrium of a free market economy. Part II considers regulated labour markets resulting from labour disputes, trade unions and government action. The 2nd edition (1963) includes a ...
Keynes's simplified starting point is this: assuming that an increase in the money supply leads to a proportional increase in income in money terms (which is the quantity theory of money), it follows that for as long as there is unemployment wages will remain constant, the economy will move to the right along the marginal cost curve (which is ...
The supply and demand model describes how prices vary as a result of a balance between product availability and demand. The graph depicts an increase (that is, right-shift) in demand from D 1 to D 2 along with the consequent increase in price and quantity required to reach a new equilibrium point on the supply curve (S).
