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 rates plotted vertically and the amount of labour that an individual or group of ...
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 ...
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.
Joan Robinson, who herself was considered an expert on the writings of Karl Marx, [73] wrote that the labor theory of value was largely a tautology and "a typical example of the way metaphysical ideas operate". [74] In ecological economics, the labor theory of value has been criticized, where it is argued that labor is in fact energy over time ...
Without referring explicitly to Marx's work on the labour theory of value of David Ricardo, the marginal utility theorist William Stanley Jevons clearly stated the main criticism of the concept of abstract labour in his 1871 treatise: "Labour affects supply, and supply affects the degree of utility, which governs value, or the ratio of exchange.
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 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.
Mirowski (1989) for example accuses Marx of vacillating between a field theory (labour-time currently socially necessary) and a substance theory of value (embodied labour-time). This kind of criticism is due to a confusion of the process of labour in general (adding use to a product, which under capitalism equates adding value to a commodity ...
