Impact of Credit Constraints on the Multiplier's Size Across the Business Cycle
The aggregate marginal propensity to consume (MPC) is determined by the relative shares of credit-constrained households, who have an MPC close to one, and unconstrained households, with an MPC near zero. During a recession, the proportion of credit-constrained households is expected to increase. This shift raises the economy-wide average MPC, which in turn increases the size of the multiplier.

Impact of Credit Constraints on the Multiplier's Size Across the Business Cycle
In a simplified economy, 60% of households are able to perfectly smooth their consumption over time, meaning they do not change their spending when their income temporarily changes. The remaining 40% of households are constrained and spend any additional income they receive immediately. What is the aggregate marginal propensity to consume (MPC) for this entire economy?
Comparing Consumption Behavior in Two Economies
Interpreting the Aggregate MPC
An economy consists of two types of households. Type A households can borrow and save freely, allowing them to keep their spending stable even when their income fluctuates. Type B households face borrowing difficulties and immediately spend any additional income they receive. If a new government policy makes it significantly easier for Type B households to access small loans, what is the most likely effect on the economy's aggregate marginal propensity to consume (MPC)?

Analyzing the Impact of an Economic Shock
Consider an economy with two types of households: those who can borrow and save to keep their consumption stable regardless of temporary income changes, and those who are unable to borrow and spend any income they receive immediately. If this economy experiences a severe recession, leading to widespread job losses, what is the most likely effect on the economy-wide average marginal propensity to consume (MPC) and the size of the spending multiplier?
The Multiplier's Behavior Over the Business Cycle
During an economic expansion, when incomes are rising and unemployment is low, the spending multiplier is at its largest because households have more disposable income to spend.
Arrange the following events in the correct logical sequence to explain how an economic downturn affects the spending multiplier.
The Multiplier's Sensitivity to Economic Conditions
Match each economic condition to the description of how it affects household borrowing, the average tendency to spend, and the overall economic response to a change in spending.
During an economic recession, as a larger share of the population finds it difficult to borrow money, the economy-wide average marginal propensity to consume tends to rise. Consequently, the overall spending multiplier is expected to ______.
A government is planning a fiscal stimulus package of a fixed amount. Economic advisors are debating whether to implement it during the current deep recession or wait until the economy enters a strong expansion phase next year. To maximize the stimulus's impact on total economic output, which scenario is preferable, and what is the underlying reason?
