Definition
The Marginal Propensity to Import (MPM) is defined as the change in imports resulting from a change in disposable income. In simpler terms, it measures how much more a country will import when its income increases—like when people get a raise and start planning their next beach holiday in Mexico!
Comparison Table
| MPM (Marginal Propensity to Import) | MPC (Marginal Propensity to Consume) |
|---|---|
| Measures the increase in imports with increasing income | Measures the increase in consumption with increasing income |
| Affects trade balances and foreign exchange dynamics | Influences domestic demand and economic growth |
| Commonly higher in developing economies | Generally high in most economies but influenced by local resources |
| Indicates the economy’s integration with global markets | Reflects the willingness to spend within the local economy |
Examples
-
Consumer Behavior: If a nation experiences a rise in household income by $1,000, and the MPM is 0.2, this implies that the country’s imports will increase by $200. It turns out Austrian strudel is more appealing at those higher income brackets!
-
Economic Impact: In countries like the U.S. where MPM might be higher due to various disposable goods, a booming tech sector can lead to a delightful influx of gadgets from around the world.
