Calculating the Multiplier in the Investment Shock Example

Analyzing an Economic Downturn

An economy experiences a sudden, autonomous decrease in investment spending of €15 billion. In this economy, households tend to spend 60% of any change in their income. Which statement best describes the immediate impact and the subsequent process?

An economy experiences a sudden €15 billion decrease in investment. Given that households in this economy spend 60% of any change in their income, arrange the following events to correctly describe the initial stages of the resulting economic contraction.

An economy experiences an autonomous reduction in investment of €15 billion, which leads to an initial €15 billion fall in aggregate income. Given that the marginal propensity to consume is 0.6, the second-round reduction in consumption spending caused by this initial income drop will be €____ billion.

True or False: In an economy where households spend 60% of any change in their income, a €15 billion autonomous reduction in investment will ultimately cause the economy's total output to fall by exactly €15 billion.

Explaining the Multiplier Effect in a Downturn

Analysis of a Negative Demand Shock

An economy experiences an initial €15 billion reduction in investment. This leads to a fall in income, and households react by reducing their spending by 60 cents for every euro of lost income, triggering further rounds of falling income and spending. Match each concept from this scenario to its correct description or value.

An economy experiences an autonomous €15 billion decrease in investment spending. If households in this economy consistently reduce their spending by 60 cents for every one-euro decrease in their income, what will be the total resulting decrease in the economy's output once all rounds of spending adjustments are complete?

An economy experiences an autonomous reduction in investment of €15 billion. In this economy, the marginal propensity to consume is 0.6, leading to a significant total decrease in output. If an otherwise identical economy with a marginal propensity to consume of 0.4 experienced the same €15 billion reduction in investment, what would be the comparative effect on its total output?
