A: The common notation for the "intercept" term of an equation specified as Y = a + bX. Mathematically, the a-intercept term indicates the value of the Y variable when the value of the X variable is equal to zero. Theoretically, the a-intercept is frequently used to indicate exogenous or independent influences on the Y variable, that is, influences that are independent of the X variable. For example, if Y represents consumption and X represents national income, a measures autonomous consumption expenditures.

PARETO EFFICIENCY: A type of efficiency that results if one person can not be made better off without making someone else worse off. Named after Vilfredo Pareto, this criterion is the guiding theoretical notion of efficiency used in the study of economics, especially welfare economics. Pareto efficiency is generally not attained if some resources are idle or unemployed. By engaging idle resources in production, some people can have more production without reducing that available to others. A problem with Pareto efficiency, however, is that it is based on the existing distribution of income and wealth. This is one of two noted efficiency criteria used in economics. The other is Kaldor-Hicks efficiency.

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.

Today, you are likely to spend a great deal of time visiting every yard sale in a 30-mile radius hoping to buy either a tall storage cabinet with five shelves and a secure lock or a birthday greeting card for your grandmother. Be on the lookout for strangers with large satchels of used undergarments.
