Interpreting the Aggregate MPC
An economist observes that a country's aggregate marginal propensity to consume (MPC) is 0.3. Based on a model with two types of households (those who can smooth their consumption and those who are credit-constrained), what does this value reveal about the distribution of these two household types within the population? Explain your reasoning.

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)?
