Consumption is an affine function of income, C = a + bY where the slope coefficient b is called the marginal propensity to consume. If any of the components of aggregate demand, a, I p or G rises, for a given level of income, Y, the aggregate demand curve shifts up and the intersection of the AD curve with the 45-degree line shifts right ...
Price-consumption curves are constructed by taking the intersection points between a series of indifference curves and their corresponding budget lines as the price of one of the two goods changes. [1] Price-consumption curves are used to connect concepts of utility, indifference curves, and budget lines to supply-demand models. [1]
A set of graphs shows the relationship between demand and revenue (PQ) for the specific case of a linear demand curve. As price decreases in the elastic range, the revenue increases, but in the inelastic range, revenue falls. Revenue is highest at the quantity where the elasticity equals 1.
The line at 45 degrees thus represents perfect equality of incomes. The Gini coefficient can then be thought of as the ratio of the area that lies between the line of equality and the Lorenz curve (marked A in the diagram) over the total area under the line of equality (marked A and B in the diagram); i.e., G = A/(A + B).
A common and specific example is the supply-and-demand graph shown at right. This graph shows supply and demand as opposing curves, and the intersection between those curves determines the equilibrium price. An alteration of either supply or demand is shown by displacing the curve to either the left (a decrease in quantity demanded or supplied ...
The statistics may suggest going for it on fourth-and-2, but if the third-string left guard is being manhandled by the all-pro defensive tackle, the analytics – with input from "ideal ...

Its simplest form is the linear consumption function used frequently in simple Keynesian models: [4] C = a + b ⋅ Y d {\displaystyle C=a+b\cdot Y_{d}} where a {\displaystyle a} is the autonomous consumption that is independent of disposable income; in other words, consumption when disposable income is zero.
