MARGINAL PROPENSITY FOR GOVERNMENT PURCHASES: The proportion of each additional dollar of national income that is used for government purchases. Or alternatively, this is the change in government purchases due to a change in national income. Abbreviated MPG, the marginal propensity for government purchases is the slope of the government purchases line used in the analysis of Keynesian economics. As such, it also plays a role in the slope of the aggregate expenditure line and the multiplier effect.

- At one end of the elasticity continuum is perfectly elastic:
- Perfectly elastic is an elasticity alternative in which infinitesimally small changes in one variable (price) cause infinitely large changes in another variable (quantity).
- This works for both the price elasticity of demand and the price elasticity of supply, because the negative value of the price elasticity of demand is ignored.
- Perfectly elastic demand and supply are represented by horizontal demand and supply curves.

PRIVATE GOODS Goods characterized by rival consumption and the ability to exclude nonpayers. Private goods are one of four types of goods differentiated by consumption rivalry and nonpayer excludability. The other three goods are public (nonrival consumption and nonpayers cannot be excluded), common-property (rival consumption and nonpayers cannot be excluded), and near-public (nonrival consumption and nonpayers can be excluded). Rival consumption and the ease of excluding of nonpayers means private goods can be efficiently exchanged through markets.
