COMMON-PROPERTY GOOD: A good that's difficult to keep nonpayers from consuming, but use of the good by one person prevents use by others. Examples include oceans, the atmosphere, many lakes and streams, and large tracts of wilderness area or public parks. The term "common property" aptly describes the situation here, it's commonly owned and thus everyone has access to it, but it can be easily used up or destroyed. Many of our pollution problems occur because common property becomes a convenient place to dump waste materials. For efficiency, government needs to take charge of common-property goods, private exchange through markets can't do the job.

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.
