2. A temporary change in the price of oil can affect an economy in many ways. Here we will model a decrease in the price of oil using the aggregate demand-aggregate supply model. Our shock in this question will be: the price of oil temporarily declines, holding all else constant. Let's start with assuming the US was producing at the full- employment level of output (Yp) with an arbitrary price level (P) before the decline in oil prices. a. Represent the US economy at this point with an aggregate demand-aggregate supply graph. Label this initial equilibrium as point A.

### Temporary Change in Oil Prices and Economic Impact

**2.** A temporary change in the price of oil can affect an economy in many ways. Here, we will model a decrease in the price of oil using the aggregate demand-aggregate supply model. Our shock in this question will be: **the price of oil temporarily declines, holding all else constant.**

Let's start by assuming the US was producing at the full-employment level of output (Yp) with an arbitrary price level (P) before the decline in oil prices.

**a.** Represent the US economy at this point with an aggregate demand-aggregate supply graph. Label this initial equilibrium as **point A**.

**b.** The price of oil decreases as mentioned above. Assuming this was the only change in the economy, show how this affects the short-run equilibrium in your diagram in part **a**. Label this new point as **point B**.

**c.** According to your diagram, is this economy in an expansion or a recession? Explain.

**d.** Is the economy experiencing stagflation? Why or why not?

### Explanation of the Diagram:

- The diagram mentioned would typically include:
  - **Aggregate Demand (AD) Curve**: Downward sloping, representing the demand for total goods and services in the economy at different price levels.
  - **Aggregate Supply (AS) Curve**: Upward sloping in the short run, representing the total goods and services that firms are willing to produce at different price levels.
  - **Initial Equilibrium (Point A)**: The intersection of the initial AD and AS curves, indicating the full-employment level of output (Yp) and initial price level (P).
  - After the fall in oil prices, the **AS Curve** would shift right as production costs decrease, leading to a new equilibrium at **Point B**.
  
- **Point B**: This represents the new short-run equilibrium with a potentially higher output and lower price level due to the decrease in oil prices, assuming all other factors remain constant.
