Where is aggregate expenditures, is autonomous expenditures , is the marginal propensity to spend (the fraction of additional income spent), and is national income (or economic output). Since b < 1 {\displaystyle b<1} the angle of this line will always be less than 45 degrees.
For oil-export-dependent economies, there could be substantial differences between real GDP and real GDI, due the effect of oil price volatility on the purchasing power in those countries. [1] [2] In the United States National Income and product accounts, the word GDI is use to define GDP calculated with income data rather than expenditure data ...
