The Significance and Insignificance of Demand Analysis in Evaluating Promotion Programs


  • George C. Davis


The estimated effects of promotion on demand are often small and insignificant. Yet, the estimated effects of promotion on industry profit are often positive and large. This puzzle is explained by demonstrating that (in)significance of promotion in a demand equation does not imply, and is not implied by, (in)significance of promotion in an industry profit equation. A Monte Carlo example is provided. The econometric modeling implications are discussed. The short-run marginal effect of a dollar of generic beef promotion on slaughter cattle industry profit is estimated to be about $9.84 with a standard error of 3.77 for 1997.
