While competitive dynamics scholars have been keenly interested in what drives competitive action, the cognitive and psychological antecedents to action are far from clearly understood. We explore the role of a specific psychological antecedent - status, in impacting firms’ motivations to launch competitive moves against rivals. The key question, which extant literature does not seem fully equipped to answer, is when and under exactly what circumstances lower- status firms become motivated to launch action against higher-status ones and vice-versa. We use the stimulus-response model in social cognition to build theory which helps to answer the question by considering structural properties of market engagement. We test theory through a field study on gourmet food trucks in an American college town. Three consequences follow from our study – that high-status firms are likely to come under attack from lower-status firms with whom they do not compete in markets, that they are unlikely to be paying attention to those lower-status firms when first attacked, and that they are likely to become aware of and motivated to act against those lower-status firms only after the lower-status firms have occupied key markets.
