This paper explores how two understudied characteristics of a firm's product portfolio, namely, aging of products and (non)innovativeness of products, affect firm survival. The influence of these product portfolio characteristics on organizational mortality can be observed both at the firm and at the industry levels. Paradoxically, the portfolio's influence at the firm and at the industry levels may go in opposite directions. Specifically, I predict that portfolios with aging products make their firms weaker competitors and survivors. However by weakening these firms, “aging” portfolios reduce competitive pressures at the industry level and, therefore, improve firm survival indirectly by changing industry vital rates. In contrast, firms with innovative product portfolios should be stronger survivors. At the same time, they are likely to intensify competition in the industry and, as a result, diminish survival chances of all firms, including those with innovative products. The analyses of all firms’ product portfolios in the worldwide optical disk drive industry, 1983–1999, support these predictions.

Recent years have seen an upsurge of interest in the study of emotions in organizations. Research, however, has been hampered by the ephemeral nature of emotions and a lack of an integrated multi-level model. This article therefore presents a five-level model of emotions in organizations. At the lowest level is within-person variation, defined in terms of affective events theory. Levels of the model then proceed through individual, dyadic relationship, group, and organization-wide perspectives. The article also outlines the neurophysiological processes that underlie the experience, perception, and communication of emotion; it concludes with a discussion of implications for research and practice.

The increasing pace of global competition has recast the balance between multinational corporations’ (MNCs’) needs to protect the knowledge that underlies their competitive advantages and their needs to continually create new knowledge. This essay will discuss MNCs’ knowledge-seeking strategies as industry-level phenomena. I will argue that knowledge-seeking strategies demand a concept of industries both as arenas for competition and as global knowledge networks within which firms collaborate to innovate. Contemporary MNCs face challenges to function not only as self-contained production systems that internationalize in the search for efficiency and markets, but also as open systems globally seeking knowledge and innovations. Metanational strategies and organizations represent a new response to these challenges. I present empirical evidence of distinctive metanational industry opportunities and organizational responses from the emergence of the global flat panel display industry. The essay concludes with a framework that outlines the characteristics of a global knowledge-driven generic strategy as an alternative and synthesis of generic product-driven strategies of cost-leadership and differentiation.
