VON THUNEN MODEL: A model of land use develop by Johann von Thunen that illustrates the trade off between land values and the distance from a central point of attraction. While originally applied to agricultural land use, the von Thunen model is commonly used to explain urban land use patterns. Two primary conclusions from the model are (1) that land values decrease as distance from the central point of attraction increases and (2) that different land use activities are contained in concentric rings equal distance from the central point of attraction based on the weight (or transportation cost) of the activity.

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.

A related marginal measure is the marginal propensity to consume.
