KEYNESIAN CROSS: The standard diagram used in Keynesian economics to identify the equilibrium level of aggregate output (that is, gross domestic product), with aggregate expenditures measured on the vertical axis, and aggregate output measured on the horizontal axis. This diagram contains two key lines, the aggregate expenditure line and the 45-degree line. Intersection between these lines indicates equilibrium aggregate output. This intersection, or cross, is what gives rise to the name.

MARGINAL PROPENSITY TO INVEST The change in business investment expenditures induced by a change in income or production (national income or gross domestic product). The marginal propensity to invest (abbreviated MPI) is another term for the slope of the investment line and is calculated as the change in investment divided by the change in income or production. The MPI plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part to the multiplier process. A related marginal measure is the marginal propensity to consume.
