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.

Aggregate Supply
In much the same way that the market supply lesson parallels the market demand lesson, this lesson on aggregate supply parallels the aggregate demand lesson. Aggregate supply however, is somewhat more involved that market supply, in particular, because aggregate supply is separated into two relations -- on for the short run and one for the long run. This lesson examines the relation between the price level and real production and the determinants that cause a change in aggregate supply, with a close eye on the differences between aggregate supply in the short run and the long run. - This lesson begins with an introduction to the aggregate supply half of the aggregate market in the first unit.
- The second unit then explores the different aggregate supply relations that exist between the price level and real production in the short run and the long run.
- The third unit introduces the short run aggregate supply curve and the long run aggregate supply curve which capture these two alternative relations.
- We think pick up the keep curve shifting determinants of aggregate supply in the fourth unit, especially the resource quantity, resource quality, and resource prices.
- The fifth unit wraps up this lesson with a discussion of the self-correction mechanism that relies on changes in the aggregate supply and how this relates to business cycle stabilization.

SCIENCE A discipline, or topic of study, that uses the scientific method to investigate and explain the operation of the world by testing and verifying hypothesized relations. Science is commonly divided into physical sciences (including chemistry, physics, and biology) and social sciences (including economics, sociology, and political science). Science is not just a subject, but a method of investigation using the scientific method.
