MARGINAL PROPENSITY TO IMPORT: The proportion of each additional dollar of household income that is used for imports. Or alternatively, this is the change in imports due to a change in disposable income. Abbreviated MPI, the marginal propensity to import plays a minor role in modifying the aggregate expenditure line and the multiplier effect.

                           AGGREGATE DEMAND AND MARKET DEMAND: The aggregate demand curve, or AD curve, has similarities to, but differences from, the standard market demand curve. Both are negatively sloped. Both relate price and quantity. However, the market demand curve is negatively sloped because of the income and substitution effects and the aggregate demand curve is negatively sloped because of the real-balance, interest-rate, and net-export effects. | Two Similar Curves |

To illustrate the specific aggregate demand and market demand curve similarities and differences consider the graph of a negatively sloped curve displayed here. Is this a market demand curve or an aggregate demand curve? A cursory look suggests that it could be either.To reveal the similarities between the both curves, click the [Market Demand] and [Aggregate Demand] buttons. Doing so illustrates that both curves are negatively sloped, with each virtually overlaying the other. Consider the differences between these two curves. - First, note that for the market demand curve, the vertical axis measures demand price and the horizontal axis measures quantity demanded. For aggregate demand curve, however, the vertical axis measures the price level (GDP price deflator) and the horizontal axis measures real production (real GDP).
- Second, the negative slope of the market curve reflects the law of demand and is attributable to the income effect and the substitution effect. In contrast, the negative slope of the aggregate demand curve is based the real-balance effect, interest-rate effect, and net-export effect. Similar, but different.
Most notable, the differences between market demand and aggregate demand mean that it is not possible to merely add up, or aggregate, the market demand curves for the thousands of goods produced in the economy to derive the aggregate demand curve. The aggregate demand curve dances to its own music and plays be its own set of rules.
