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 45-degree line represents an aggregate supply curve which embodies the idea that, as long as the economy is operating at less than full employment, anything demanded will be supplied. Aggregate expenditure and aggregate income are measured by dividing the money value of all goods produced in the economy in a given year by a price index.
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 ...
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.
Finally, wages and prices are assumed to be elastic (they move up and down freely). The classical model assumes that traditional supply and demand analysis is the best approach to understanding the labor market. The functions that follow are aggregate functions that can be thought of as the summation of all the individual participants in the ...
Isocost v. isoquant graph. Each line segment is an isocost line representing one particular level of total input costs, denoted TC, with P L being the unit price of labor and P K the unit price of physical capital. The convex curves are isoquants, each showing various combinations of input usages that would give the particular output level ...
The markup reflects both the firm's degree of market power and the extent to which overhead costs have to be paid. Put another way, all else equal, M rises with the firm's power to set prices or with a rise of overhead costs relative to total costs. So pricing follows this equation: P = M × (unit labor cost) + (unit materials cost)
