Price Elasticity
1. **Problem Statement:**
Given the price elasticity of demand (EOD) for various goods, we want to find the effect on quantity demanded if the price of Alcoholic drinks increases by 5%. Also, we need to suggest a price strategy for each product to increase revenue.
2. **Recall the formula for price elasticity of demand:**
$$EOD = \frac{\% \text{ change in quantity demanded}}{\% \text{ change in price}}$$
3. **Calculate the change in quantity demanded for Alcohol:**
Given:
- Price EOD for Alcohol = $-0.83$
- Price increase = $5\%$
Using the formula:
$$\% \text{ change in quantity demanded} = EOD \times \% \text{ change in price} = -0.83 \times 5 = -4.15\%$$
This means quantity demanded will decrease by 4.15% when price increases by 5%.
4. **Interpretation:**
Since the elasticity is negative (as expected), an increase in price leads to a decrease in quantity demanded.
5. **Price strategy to increase revenue:**
- For goods with $|EOD| < 1$ (inelastic demand), increasing price increases total revenue.
- For goods with $|EOD| > 1$ (elastic demand), decreasing price increases total revenue.
From the table:
- Fuel & Light: $EOD = -0.47$ (inelastic) → Increase price to increase revenue.
- Food: $EOD = -0.52$ (inelastic) → Increase price to increase revenue.
- Alcohol: $EOD = -0.83$ (inelastic) → Increase price to increase revenue.
- Dairy Produce: $EOD = -0.05$ (highly inelastic) → Increase price to increase revenue.
6. **Summary:**
- Quantity demanded for Alcohol decreases by 4.15% if price increases by 5%.
- For all goods listed, since demand is inelastic, raising prices will increase total revenue.
