GOVERNMENT PURCHASES OF GOODS AND SERVICES: Expenditures on final goods and services (that is, gross domestic product) undertaken by the government sector. The official entry for government purchases in the National Income and Product Accounts maintained by the Bureau of Economic Analysis is termed government consumption expenditures and gross investment. Government purchases are used to operate the government (administrative salaries, etc.) and to provide public goods (national defense, highways, etc.). Government purchases do not include other government spending for transfer payments. These are expenditures on final goods by all three levels of government: federal, state, and local governments.

SLOPE, INVESTMENT LINE: The positive slope of the investment line is also termed the marginal propensity to invest (MPI). This slope is greater than zero but less than one, reflecting induced investment. The slope of the investment line affects the slope of the aggregate expenditures line and thus also affects the magnitude of the multiplier process. Investment Line |
| The investment line, also termed propensity-to-invest line or investment function, shows the relation between investment expenditures by the business sector and the level of aggregate income or production. The income and production measures most commonly used are national income and gross domestic product.A representative investment line is presented in the exhibit to the right. This red line, labeled I in the exhibit, is positively sloped, indicating that greater levels of income or production generate greater investment expenditures by the business sector. This positive relation indicates that the business sector is inclined to divert higher profits generated by an expanding economy to investment expenditures on capital goods. The investment line graphically illustrates the investment-income relation for the business sector, which plays a key role in the aggregate expenditures line used in Keynesian economics to identify equilibrium income and production. The slope of the investment line presented here is positive, but less than one. In fact, the slope of the investment line is numerically equal to the marginal propensity to invest. In this case the slope is equal to 0.1. The positive slope reflects induced investment expenditures--more income means more investment. Click the [Slope] button to illustrate. To illustrate the equality between slope and the marginal propensity to invest, consider the equations for each. The slope of the investment line is specified as the "rise" over the "run." The rise is the change in investment measured on the vertical axis and the run is the change in income measured on the horizontal axis. slope | = | rise run | = | change in investment change in income |
The marginal propensity to invest (MPI) is the incremental change in investment resulting from an incremental change in income. MPI | = | change in investment change in income |
The slope of the investment line is the marginal propensity to invest, they are one and the same.The positive slope of the investment line reflects induced investment, which is investment that depends on the level of income. If the aggregate economy has more income, then the business sector is induced to undertake additional investment expenditures. Of course, a drop in aggregate income induces the business sector to reduce expenditures.
