Aggregate MPC as an Average
The aggregate marginal propensity to consume (MPC) for an entire economy should be understood as an average value that reflects the varied consumption behaviors of all households. It consolidates the different MPCs of various groups, such as high-MPC, low-wealth households and low-MPC, wealthy households, into a single representative figure for the economy as a whole.

Assumption about the Range of the Marginal Propensity to Consume (MPC)
Example of a Marginal Propensity to Consume (MPC) of 0.6
An economy experiences a $200 billion increase in aggregate disposable income. As a result, aggregate consumption spending rises from $800 billion to $950 billion. Based on this information, what is the marginal propensity to consume (MPC) for this economy?
Two households, the Smith family and the Jones family, each receive an unexpected one-time bonus of $1,000. The Smith family's marginal propensity to consume is 0.9, while the Jones family's is 0.6. Which statement best analyzes the immediate effect of this bonus on their spending?
Economic Stimulus Policy Evaluation
A household earns a disposable income of $60,000 per year and spends $45,000 on consumption. Based on this information, the household's marginal propensity to consume is 0.75.
Calculating Change in Consumption
An unexpected, one-time government payment is distributed to all citizens. Which of the following individuals is most likely to have the highest marginal propensity to consume with respect to this payment?
Evaluating Economic Stimulus Policies
Consider two economies, A and B, with the following aggregate consumption functions where C is consumption and Yd is disposable income (both in billions of dollars):
- Economy A: C = 200 + 0.8Yd
- Economy B: C = 500 + 0.5Yd
If both economies experience an identical $100 billion increase in aggregate disposable income, which statement accurately compares the resulting change in consumption?
An economic report observes that for every additional dollar of disposable income households receive, they tend to increase their savings by $0.25. Based on this information, what is the implied marginal propensity to consume (MPC)?

Consider an economy where a new government policy results in a significant redistribution of income from the wealthiest 10% of households to the bottom 40% of households. Assuming no other changes, what is the most likely immediate impact on the economy's aggregate marginal propensity to consume (MPC)?
Explaining Changes in Aggregate Consumption Behavior
A government is considering two tax cut policies of the exact same total value. Policy A gives the entire tax cut to the wealthiest 1% of households, while Policy B distributes the same total amount evenly among the poorest 50% of households. Both policies will have an identical impact on total consumption in the economy.
