NORMATIVE ECONOMICS: The branch of economics that states the way the economy should operate. A normative statement is based on values and can be proved neither right or wrong. While positive economics seeks to explain the way it is, normative economics, the policy side of economics, seeks to prescribe the way it should be. Normative economics is used to recommend ways to change the world, to improve it, and to make it a better place for both man and beast.

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.
