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.
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] It is often represented as a curve in a graph with quantities of two inputs, typically physical capital and labor , plotted on the axes.
In a model where competitive consumers optimize homothetic utility functions subject to a budget constraint, the ratios of goods demanded by consumers will depend only on relative prices, not on income or scale. This translates to a linear expansion path in income: the slope of indifference curves is constant along rays beginning at the origin.
The consumer's demand is always to get the goods in constant ratios determined by the weights, i.e. the consumer demands a bundle (, …,) where is determined by the income: = / (+ +). [1] Since the Marshallian demand function of every good is increasing in income, all goods are normal goods .
As the target level of output is increased, the relevant isoquant becomes farther and farther out from the origin, and still it is optimal in a cost-minimization sense to operate at the tangency point of the relevant isoquant with an isocost curve. The set of all such tangency points is called the firm's expansion path.
When measured from the income side, the economy grew at a 2.1% rate last quarter, lowered from the initially estimated 2.2% pace. Gross domestic income (GDI) increased at a 2.0% rate in the second ...
If you need a little nudge, just think of the passive income you stand to earn by taking the leap. “Most target 15%-30% total returns and many of those investments include a 4%-10% income yield ...
