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 ]
A firm's production function could exhibit different types of returns to scale in different ranges of output. Typically, there could be increasing returns at relatively low output levels, decreasing returns at relatively high output levels, and constant returns at some range of output levels between those extremes.
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.
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 business cycle may be defined as the period between two consecutive peaks. [1] [2] The period of the business cycle in which real GDP is increasing is called the expansion, in which the real GDP moves from the trough towards the peak. [3]
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 ...
Shortly after, Mason Haire was among the initial researchers [13] who suggested that organisations may adhere to a certain path of uniformity in their course of expansion. [ 14 ] Subsequently, research has been done on the organizational life cycle for more than 120 years [ 10 ] and can be found in various literature on organizations . [ 15 ]
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 ...
