Abstract: Understanding sources of sustained competitive advantage has become a major area of research in strategic management. Building on the assumptions that strategic resources are heterogeneously distributed across firms and that these differences are stable over time, this article examines the link between firm resources and sustained competitive advantage. Four empirical indicators of the potential of firm resources to generate sustained competitive advantage-value, rareness, imitability, and substitutability are discussed. The model is applied by analyzing the potential of several firm resources for generating sustained competitive advantages. The article concludes by examining implications of this firm resource model of sustained competitive advantage for other business disciplines.

Abstract: Self-reports figure prominently in organizational and management research, but there are several problems associated with their use. This article identifies six categories of self-reports and discusses such problems as common method variance, the consistency motif, and social desirability. Statistical and post hoc remedies and some procedural methods for dealing with artifactual bias are presented and evaluated. Recommendations for future research are also offered.

Abstract: Social exchange theory (SET) is one the most influential conceptual paradigms in organizational behavior. Despite its usefulness, theoretical ambiguities within SET remain. As a consequence, tests of the model, as well as its applications, tend to rely on an incompletely specified set of ideas. The authors address conceptual difficulties and highlight areas in need of additional research. In so doing, they pay special attention to four issues: (a) the roots of the conceptual ambiguities, (b) norms and rules of exchange, (c) nature of the resources being exchanged, and (d) social exchange relationships.

Abstract: The rapid growth of research on organizational citizenship behaviors (OCBs) has resulted in some conceptual confusion about the nature of the construct, and made it difficult for all but the most avid readers to keep up with developments in this domain. This paper critically examines the literature on organizational citizenship behavior and other, related constructs. More specifically, it: (a) explores the conceptual similarities and differences between the various forms of “citizenship” behavior constructs identified in the literature; (b) summarizes the empirical findings of both the antecedents and consequences of OCBs; and (c) identifies several interesting directions for future research.

Abstract: Previous organizational citizenship behavior (OCB) research (a) has not demonstrated that extra-role behaviors can be distinguished empirically from in-role activities, and (b) has not examined the relative contributions of components ofjob satisfaction a nd organizational commitment to the performance of OCBs. Factor analysis of survey data from 127 employees' supervisors supported the distinction between in-role behaviors and two forms of OCBs. Hierarchical regression analysis found two job cognitions variables (intrinsic and extrinsic) to be differentially related to the two types OCBs, but affective variables and organizational commitment were not significant predictors. The link between the present findings and previous research is discussed, as are directions forfuture research.
