GOVERNMENT PURCHASES LINE: A graphical depiction of the relation between government purchases and national income (or gross domestic product) that plays a role in Keynesian economics and the Keynesian cross. The slope of this line is positive, greater than zero, less than one, and goes by the name marginal propensity for government purchases. The vertical intercept of this line is autonomous government purchases. The aggregate expenditures line used in the Keynesian cross is obtained by adding this government purchases line, as well as, investment expenditures and net exports, to the consumption line. The government purchases line is also combined with investment expenditures for the Keynesian saving-investment model.

GROSS DOMESTIC PRODUCT The total market value of all final goods and services produced within the political boundaries of an economy during a given period of time, usually one year. This is the official measure of the aggregate output produced by the economy. It is tabulated and reported by the National Income and Product Accounts maintained by the Bureau of Economic Analysis, which is part of the U. S. Department of Commerce. Gross domestic product, often abbreviated simply as GDP, is one of several measures reported regularly (quarterly and annually) by the number crunchers at the Bureau of Economic Analysis. Other common measures include net domestic product, national income, personal income, and disposable income. GDP has replaced gross national product (GNP), in most official discussion of aggregate economic production.
