MARGINAL PROPENSITY TO CONSUME: The proportion of each additional dollar of household income that is used for consumption expenditures. Or alternatively, this is the change in consumption expenditures due to a change in disposable income. Abbreviated MPC, the marginal propensity to consume is the slope of the consumption or propensity-to-consume line that forms the foundation for Keynesian economics. As such, it also takes center stage for the slope of the aggregate expenditure line and the multiplier effect. The sum of the marginal propensity to consume and the related concept, the marginal propensity to save, is equal to one.

- Price and Marginal Cost: While monopolistic competition does not produce the quantity that equates price and marginal cost, the difference is often NOT very big.
- Different Preferences: Because monopolistic competition firms offer different products, buyers are able to satisfy different tastes and preferences.
- Monopolistic competition may actually be a BETTER market structure than perfect competition -- at least better for real world people who live in the real world.

The central feature of this short-run production analysis is the law of diminishing marginal returns, which results in the short run when larger amounts of a variable input, like labor, are added to a fixed input, like capital. A contrasting analysis is long-run production analysis.

[What's This?]
Today, you are likely to spend a great deal of time looking for a downtown retail store seeking to buy either a half-dozen helium filled balloons or a packet of address labels large enough for addresses of both the sender and the recipient. Be on the lookout for broken fingernail clippers.
