Considerable research explores advertising’s role in influencing consumer perceptions and behavior. However, advertising’s impact on another key audience—the sales force—has been largely overlooked. Drawing from social identity and expectancy theories, and using survey and objective performance data across multiple wholesalers, the authors demonstrate that a salesperson’s perception of brand advertising has a significant effect on salesperson effort and performance by positively influencing the extent to which the salesperson identifies with the brand and his or her expectancy that such effort will generate results. These effects are moderated by internal communications and brand size. Model results suggest that advertising’s role may extend beyond “pull” to “push” by motivating salespeople to exert more effort on behalf of a brand. As a result, firms should take steps to proactively manage salesperson perceptions of brand advertising while also considering this dual role when assessing advertising effectiveness and efficiency.
