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 ...
The short-run supply curve for a perfectly competitive firm is the marginal cost curve at and above the shutdown point. Portions of the marginal cost curve below the shutdown point are not part of the SR {\displaystyle {\text{SR}}} supply curve because the firm is not producing any positive quantity in that range.
Economists distinguish between short-run and long-run supply curve. Short run refers to a time period during which one or more inputs are fixed (typically physical capital), and the number of firms in the industry is also fixed (if it is a market supply curve). Long run refers to a time period during which new firms enter or existing firms exit ...
The AD–AS or aggregate demand–aggregate supply model (also known as the aggregate supply–aggregate demand or AS–AD model) is a widely used macroeconomic model that explains short-run and long-run economic changes through the relationship of aggregate demand (AD) and aggregate supply (AS) in a diagram.
A firm's short-run supply curve is the marginal cost curve above the shutdown point—the short-run marginal cost curve (SRMC) above the minimum average variable cost. The portion of the SRMC below the shutdown point is not part of the supply curve because the firm is not producing any output. [13]
Relatively elastic supply: This is when the E s formula gives a result above one, meaning that when there is a change in price, the percentage change in supply is higher than the percentage change in price. Using the above example to show an elastic supply, when there is a 10% increase in price there will be more than a 10% increase in supply.
