Ranking Advertising Intensity: A Dorfman-Steiner Model Analysis

According to the Dorfman-Steiner model, the expected intensity of advertising is directly proportional to the product of a product's advertising elasticity of demand and its price elasticity of demand. Let's analyze four industries and determine their expected advertising intensity ranking.

Industry Analysis:

• Industry 1: Advertising Elasticity of Demand: 0.8, Price Elasticity of Demand: 0.1
• Industry 2: Advertising Elasticity of Demand: 0.7, Price Elasticity of Demand: 0.4
• Industry 3: Advertising Elasticity of Demand: 0.4, Price Elasticity of Demand: 0.4
• Industry 4: Advertising Elasticity of Demand: 0.9, Price Elasticity of Demand: 0.2

Calculations:

To determine the expected advertising intensity, we'll calculate the product of advertising elasticity and price elasticity for each industry:

• Industry 1: 0.8 x 0.1 = 0.08
• Industry 2: 0.7 x 0.4 = 0.28
• Industry 3: 0.4 x 0.4 = 0.16
• Industry 4: 0.9 x 0.2 = 0.18

Ranking:

Based on these calculations, we can rank the industries in descending order of expected advertising intensity:

1. Industry 2 (0.28): Industry 2 emerges as the leader, suggesting that companies in this industry can significantly benefit from advertising due to the high product of advertising and price elasticity.

2. Industry 4 (0.18): Industry 4 secures the second position, indicating a moderate level of expected advertising intensity.

3. Industry 3 (0.16): Industry 3 follows closely, implying that advertising can still be beneficial, though potentially less impactful compared to Industries 2 and 4.

4. Industry 1 (0.08): Industry 1, with the lowest score, may not experience substantial benefits from advertising, given the low product of its advertising and price elasticity.

Conclusion:

The Dorfman-Steiner model provides valuable insights for businesses to strategize their advertising budgets. Industries with higher advertising and price elasticity combinations are likely to see greater returns on their advertising investments. However, it's crucial to remember that this model simplifies a complex reality. Other factors, such as market competition, consumer behavior, and advertising creativity, also play significant roles in determining the effectiveness of advertising campaigns.
