GIFFEN GOOD: A rare type of good seldom seen in the real world, in which a change in price causes quantity demanded to change in the same direction (in violation of the law of demand). In other words, an increase in the price of a Giffen good results in an increase in the quantity demanded. The existence of a Giffen good requires the existence of special circumstances. First, the good must be an inferior good. Second, the income effect triggered by a change in price must overwhelm the substitution effect. A Giffen good is most likely to result when the good is a significant share of the consumer's budget.

MARGINAL PROPENSITY TO SAVE The proportion of each additional dollar of household income that is used for saving. The marginal propensity to save (abbreviated MPS) is another term for the slope of the saving line and is calculated as the change in saving divided by the change in income. The MPS plays a central role in Keynesian economics. It quantifies the saving-income relation, which is the flip side of the consumption-income relation, and thus it reflects the fundamental psychological law. It is also a critical to the multiplier process. A related saving measure is the average propensity to save.
