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]
If the substitution effect is greater than the income effect, an individual's supply of labour services will increase as the wage rate rises, which is represented by a positive slope in the labour supply curve (as at point E in the adjacent diagram, which exhibits a positive wage elasticity). This positive relationship is increasing until point ...
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 ...
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 life-cycle hypothesis argues that households base their consumption decisions on expected lifetime income and so they prefer to "smooth" consumption over time. They will thus save (and invest) in periods of high income and defer consumption of this to periods of low income. The other decision is the labor-leisure tradeoff.
The substitution effect is due to the effect of the relative price change while the income effect is due to the effect of income being freed up. The equation demonstrates that the change in the demand for a good, caused by a price change, is the result of two effects:
The Frisch elasticity of labor supply captures the elasticity of hours worked to the wage rate, given a constant marginal utility of wealth. Marginal utility is constant for risk-neutral individuals according to microeconomics. In other words, the Frisch elasticity measures the substitution effect of a change in the wage rate on labor supply. [1]
The added worker effect results when the income effect dominates the substitution effect in an individual's decision whether or not to participate in the labor market. The income and substitution effects are concepts in the consumer choice theory of microeconomics. For added workers to enter the labor market when earning power decreases, the ...
