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 ...
A firm's labour demand in the short run (D) and a horizontal supply curve (S) The marginal revenue product of labour can be used as the demand for labour curve for this firm in the short run. In competitive markets , a firm faces a perfectly elastic supply of labour which corresponds with the wage rate and the marginal resource cost of labour ...
Mathematically, the LM curve is defined by the equation / = (,), where the supply of money is represented as the real amount M/P (as opposed to the nominal amount M), with P representing the price level, and L being the real demand for money, which is some function of the interest rate and the level of real income.
New classical economics made its first attempt to model aggregate supply in Lucas and Leonard Rapping (1969). [2] In this earlier model, supply (specifically labor supply) is a direct function of real wages: more work will be done when real wages are high and less when they are low. Under this model, unemployment is "voluntary". [3]
The SAS (Surprise aggregate supply) curve is in the long run a vertical line called the EAS (Equilibrium aggregate Supply) curve. The short run SAS curve is given by the equation: π = π e + λ ( Y − Y ∗ ) {\displaystyle \pi =\pi ^{e}+\lambda (Y-Y*)}
The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...
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.
