Multiplier Effect of Autonomous Demand on Equilibrium Output
A change in autonomous demand, which consists of autonomous consumption and investment , leads to a multiplied effect on the equilibrium output . Specifically, any change in autonomous demand will cause the equilibrium output to change by an amount equal to the multiplier times the initial change.

Multiplier Effect of Autonomous Demand on Equilibrium Output
Example Calculation of the Multiplier (k)
In a simplified economic model, the equilibrium output (Y) is determined by the equation Y = k(c₀ + I), where 'k' is a multiplier with a value greater than 1, 'c₀' represents spending that does not depend on income, and 'I' represents investment spending. If businesses suddenly become more pessimistic about the future and reduce their investment spending (I), while 'k' and 'c₀' remain unchanged, what will be the resulting effect on the equilibrium output (Y)?

Deconstructing the Equilibrium Output Equation
In the macroeconomic model where equilibrium output is represented by the equation
Y = k(c₀ + I), match each component of the equation to its correct economic description.Derivation of the Change in Equilibrium Output from an Investment Shock

Impact of an Autonomous Spending Shock
In a closed economy with no government sector, the marginal propensity to consume is 0.8. If autonomous investment spending increases by $100 billion, what will be the total change in the equilibrium level of output?
Calculating and Explaining the Multiplier Effect
An economy experiences a $100 million increase in autonomous investment spending. The marginal propensity to consume is 0.75. Arrange the following events to illustrate the first few rounds of the multiplier effect in the correct chronological order.
In an economy where households tend to save a larger portion of any additional income they receive, an initial increase in autonomous investment spending will lead to a larger overall increase in equilibrium output compared to an economy where households save less.
An economy is characterized by a marginal propensity to consume of 0.75. An external event causes autonomous investment to increase by $100 billion. Match each term on the left with its correct corresponding value or description on the right.
Evaluating Economic Stimulus Policies
In a simple closed economy with no government, the marginal propensity to consume is 0.6. If autonomous investment decreases by $50 billion, the total change in equilibrium output will be a decrease of $____ billion.
Two closed economies, A and B, have no government sector. In Economy A, households spend 90 cents of every extra dollar they earn. In Economy B, households spend 60 cents of every extra dollar they earn. If both economies experience an identical, positive shock to autonomous investment spending, which of the following statements accurately describes the resulting change in their respective equilibrium outputs?
In a closed economy with no government, a $20 billion decrease in autonomous investment leads to a $100 billion decrease in total equilibrium output. What is the marginal propensity to consume in this economy?
