Abstract We investigate incumbent brands’ response to entry and increased competition in a large retail setting. We extend the nonprice competition and manufacturer stocking literatures by examining if incumbent brands increase quality, specifically increasing the number of varieties (product-line length), in response to entry of a new local brand in the ice cream market. We use the entry of a new, local, super-premium ice cream brand in a large supermarket chain as a quasi-natural experiment and empirically examine if incumbent ice cream brands increased the product-line length in stores carrying the new brand. Using Poisson difference-in-differences estimators, we find that incumbent brands increased the number of varieties offered by 0.9 (3 percent) after the new brand's entry, with most of the responses coming from super-premium ice cream, which increased the number of varieties offered by 2.9 (12 percent) product choices. These findings contribute new insights into quality changes, manufacturer stocking decisions, and nonprice competition associated with entry of a local brand into the food retail sector.

Processing Mechanisms

The role of top-down processing on the horizontal-vertical line length illusion was examined by means of an ambiguous room with dual visual verticals. In one of the test conditions, the subjects were cued to one of the two verticals and were instructed to cognitively reassign the apparent vertical to the cued orientation. When they have mentally adjusted their perception, two lines in a plus sign configuration appeared and the subjects had to evaluate which line was longer. The results showed that the line length appeared longer when it was aligned with the direction of the vertical currently perceived by the subject. This study provides a demonstration that top-down processing influences lower level visual processing mechanisms. In another test condition, the subjects had all perceptual cues available and the influence was even stronger.
