Empirical investigation of channel reactions to brand introductions

摘要

We investigate how incumbent manufacturers and retailers alter their pricing behavior in response to new product introduction. In performing our analysis, we need to be cognizant of the fact that the observed price changes can be due to entry-induced changes in a) demand conditions or b) costs or, on the other hand, to the competitive behavior of c) manufacturers and/or d) the retailer. In order to separate these four changes, we posit that manufacturer and retailer pricing is an outcome of maximizing a combination of shares and profits. This enhanced objective function allows us to measure competitive conduct benchmarked as less or more competitive than under the Bertrand-Nash framework. Our empirical analysis is based on the toothpaste category for the time period January 1993-February 1995. During this period, there were three brand introductions in two rounds of entry. Using the estimates from the demand and the supply model, we compute the changes in the retail and wholesale prices that are attributable to changes in demand conditions, manufacturer and retailer competitive conduct, and cost changes. These results support our conjecture that inferring the change in conduct solely based on a change in observed prices is likely to be erroneous. For the first new brand entry, we find that the brand introduction did not significantly increase competition between manufacturers. As a result, the balance of channel power between the manufacturers and the retailers remained unaltered. Both retailer and manufacturer profit margins increased after the first entry. However, subsequent to the second entry, retailer share of channel profits increased at the expense of the manufacturers; manufacturers even saw a decline in their absolute profit margins. We believe that this research will provide insight for manufacturers and retailers regarding how the various channel participants are likely to react to new product introduction. Furthermore, policymakers interested in understanding competitive reactions to new product introduction should find this research useful.
