This paper investigates competitive tension, or the strain between a focal firm and a given rival that is likely to result in the firm taking action against the rival. Drawing on the awareness-motivation-capability perspective, we show how perceived competitive tension, as constructed from managers' and industry stakeholders' competitor assessments, is influenced by the independent and interactive effects of three factors: relative scale, rival's attack volume, and rival's capability to contest. Our results provide a new avenue for studying competitors and the relationship between competitor analysis and interfirm rivalry.

This study examines how sibship characteristics affect educational attainment in Taiwan. Using a multilevel analysis of a sibling sample of 12,715 observations from 3,001 families drawn from a national survey, we investigate the effects of family size, sibship density, birth‐order rank, and sibship gender composition. The results support the argument that the effect of son preference on intrafamily educational inequality is conditional on family resources. We also find, however, that male firstborns, who are the ultimate inheritors of paternal authority in Chinese families, have additional leverage in the sibling competition for family resources. The privilege for firstborns does not extend to daughters. Therefore, we argue that culturally defined norms regarding seniority and gender help shape intrafamily resource allocation in Chinese society.
