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 ...
An advertisement for labour from Sabah and Sarawak, seen in Jalan Petaling, Kuala Lumpur. In mainstream economic theories, the labour supply is the total hours (adjusted for intensity of effort) that workers wish to work at a given real wage rate. It is frequently represented graphically by a labour supply curve, which shows hypothetical wage ...
The direction of the slope may change more than once for some individuals, and the labour supply curve is different for different individuals. Other variables that affect the labour supply decision, and can be readily incorporated into the model, include taxation, welfare, work environment, and income as a signal of ability or social contribution.
In the original formulation of Keynesian economics in the General Theory, Keynes abandoned the classical concept that the demand and supply of labor are always equal and instead, he simply dropped the labor supply curve from his analysis. [4]
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 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 Dual Sector model, or the Lewis model, is a model in developmental economics that explains the growth of a developing economy in terms of a labour transition between two sectors, the subsistence or traditional agricultural sector and the capitalist or modern industrial sector.
The Phillips curve equation can be derived from the (short-run) Lucas aggregate supply function. The Lucas approach is very different from that of the traditional view. Instead of starting with empirical data, he started with a classical economic model following very simple economic principles. Start with the aggregate supply function:
