Question
The following graph shows the aggregate demand curve (AD₁) for this economy before the change in government spending. 

Use the green line (triangle symbol) to plot the new aggregate demand curve (AD₂) after the multiplier effect takes place. For simplicity, assume that there is no "crowding out."

Hint: Be sure that the new aggregate demand curve (AD₂) is parallel to the initial aggregate demand curve (AD₁). You can see the slope of AD₁ by selecting it on the graph.

**Graph Explanation:**

- **X-Axis (Horizontal):** Represents the Output in Trillions of dollars, ranging from 0 to 8.
- **Y-Axis (Vertical):** Represents the Price Level, ranging from 100 to 140.
- **Blue Line (AD₁):** Indicates the initial aggregate demand curve, sloping downward from a price level of 140 at output 0 to a price level of 100 at output 8.
- **Green Line:** Instructions suggest plotting the new aggregate demand curve (AD₂) parallel to AD₁ using the green line with a triangle symbol.

1. The multiplier effect of a change in government purchases

Consider a hypothetical closed economy in which households spend $0.60 of each additional dollar they earn and save the remaining $0.40.

The marginal propensity to consume (MPC) for this economy is **0.6**, and the expenditure multiplier for this economy is ____.

Suppose the government in this economy decides to **increase** government purchases by $400 billion. The increase in government purchases will lead to an increase in income, generating an initial change in consumption equal to _____________. This increases income yet again, causing a second change in consumption equal to ________________. The total change in demand resulting from the initial change in government spending is ________________.
