2. Estimating the impact of advertising for a typical product in a typical market Please answer the following question. Caution: In the past, few people could provide reasonable answers. You work for a typical firm selling a typical product in a typical market in the U.S. Last year’s sales were 50,000 units, which was typical for the firm. Last year’s advertising budget was $1 million, which was typical for the firm. You plan to spend $1.1 million on advertising this coming year by using typical advertising. How many units do you expect to sell this coming year. ___________________ units? Do your analysis and write your answer before going to the next slide. Adapted from AdPrin.com

3. Information about the products What would you estimate the unit sales if the product was: BMW cars?_______ cars Bud Light beer? _______ truck-loads Adapted from AdPrin.com

4. Elasticity method Use the elasticity method in cases where an existing product has been advertised. Advertising elasticity (or “sensitivity to advertising”) expresses the percentage change in unit sales given a one percent change in advertising expenditures. Given an estimated elasticity of 0.1, if advertising expenditure were raised by 10%, unit sales would go up by 1%. Adapted from AdPrin.com

5. Average advertising elasticities Many studies have been done to estimate the elasticity of products for various media. On average the elasticity is about 0.1 So what is the answer for the first question at the start of this exercise? 50,500 Sethuraman & Tellis (1991), "An analysis of the tradeoff between advertising and price discounting,” Journal of Marketing Research, 28, 160-174. Assmus, G, J. U. Farley & D. R. Lehmann (1984), "How advertising affects sales: Meta-analysis of econometric results," Journal of Marketing Research, 21, 65-74. Adapted from AdPrin.com

6. Elasticity by type of product Product type Durable0.23 Nondurable0.09 So what is your new answer to BMWs versus Bud Lite? BMWs more responsive to advertising. Why? More news, more information, more attention by viewers as it is high-involvement. Adapted from AdPrin.com

7. Elasticity averages by media Media Print0.13 TV0.03 Why the difference? Print has more information, and can explain news. Used more for new high-involvement products Adapted from AdPrin.com

8. Wright’s Rule Given estimates of advertising elasticity, how much should you spend on advertising? Ad expenditure = (Elasticity) x (Gross margin per unit) x (forecasted unit sales) Wright, Malcolm (2009), “A new theorem for optimizing the advertising budget,” Journal of Advertising Research, 49 (2), 164- 169.
