A curve connecting the tangency points is called the expansion path because it shows how the input usages expand as the chosen level of output expands. In economics , an expansion path (also called a scale line [ 1 ] ) is a path connecting optimal input combinations as the scale of production expands. [ 2 ]
In economics and particularly in consumer choice theory, the income-consumption curve (also called income expansion path and income offer curve) is a curve in a graph in which the quantities of two goods are plotted on the two axes; the curve is the locus of points showing the consumption bundles chosen at each of various levels of income.
The line connecting all points of tangency between the indifference curve and the budget constraint as the budget constraint changes is called the expansion path, [11] and correlates to shifts in demand. The line connecting all points of tangency between the indifference curve and budget constraint as the price of either good changes is the ...
An economic expansion is an upturn in the level of economic activity and of the goods and services available. It is a finite period of growth, often measured by a rise in real GDP , that marks a reversal from a previous period, for example, while recovering from a recession .
A range of periods rather than one fixed period is needed to capture business cycle fluctuations, which may be done by using a random or irregular source as in an econometric or statistical framework. The Kuznets infrastructural investment cycle of 15 to 25 years (after Simon Kuznets – also called "building cycle")
If the firm is a perfect competitor in all input markets, and thus the per-unit prices of all its inputs are unaffected by how much of the inputs the firm purchases, then it can be shown that at a particular level of output, the firm has economies of scale if and only if it has increasing returns to scale, has diseconomies of scale if and only ...
He distinguished between the temporary or market period (with output fixed), the short period, and the long period. "Classic" contemporary graphical and formal treatments include those of Jacob Viner (1931), [15] John Hicks (1939), [16] and Paul Samuelson (1947). [17] [18] The law is related to a positive slope of the short-run marginal-cost ...
Macroeconomics is traditionally divided into topics along different time frames: the analysis of short-term fluctuations over the business cycle, the determination of structural levels of variables like inflation and unemployment in the medium (i.e. unaffected by short-term deviations) term, and the study of long-term economic growth.
