Transcribed Image Text:**8. Short-run and long-run effects of a shift in demand**
Suppose that the chicken industry is in long-run equilibrium at a price of $5 per pound of chicken and a quantity of 50 million pounds per year. Suppose that WebMD claims that a protein found in chicken will increase your expected lifespan by 3 years.
WebMD’s claim will cause consumers to demand more ▼ chicken at every price. In the short run, firms will respond by __________________________________________ ▼.

Transcribed Image Text:### Understanding Supply and Demand Shifts
The graph you see illustrates the short-run effects related to supply and demand. The goal is to understand how these curves can shift in response to external claims, such as those made by WebMD.
**Graph Explanation:**
- **Axes:**
- The horizontal axis represents Quantity (Millions of pounds).
- The vertical axis represents Price (Dollars per pound).
- **Curves:**
- The **Supply** curve is shown in orange, sloping upwards from left to right, indicating that as the price increases, the quantity supplied increases.
- The initial **Demand** curve, labeled as \(D_1\), is shown in blue. It slopes downwards, indicating that as the price decreases, the quantity demanded increases.
- The shifted **Demand** curve, labeled as \(D_2\), is also shown in blue. It represents a change in demand due to an external factor.
- **Equilibrium:**
- The initial equilibrium is indicated by the intersection of the supply curve and the initial demand curve \(D_1\).
- The black dashed lines at the new equilibrium show price and quantity adjustments as the demand curve shifts to \(D_2\).
**Short-run versus Long-run Adjustments:**
- In the **short run**, market adjustments may occur due to sudden changes in demand, such as those influenced by external claims impacting consumer behavior.
- In the **long run**, some firms may respond by:
- **Exiting the industry** if they can’t compete with changes.
- Adjusting output as **chicken populations grow large enough to support more firms**.
This graph exemplifies basic economic principles of supply and demand, emphasizing how external factors can lead to shifts and market responses over time.
