Controlling for endogeneity with instrumental variables in strategic management research


Strategic Organization

août 2008, vol. 6, n°3, pp.285-327

Départements : Stratégie et Politique d’Entreprise

Mots clés : Causal relations, Endogeneity, Instrumental variables

This article offers a framework to understand how endogeneity arises and how to control for it with instrumental variables to estimate causal relations with observational data. It builds on the state-of-the-art research in applied and theoretical econometrics to highlight the importance of endogeneity and review the methods that can be used to address it with instrumental variables,The article also discusses when the Heckman two-step procedure can be used, as well as the tests, methods and assumptions that researchers should check when using instrumental variables. To ease implementation of the instrumental variables techniques, the author offers the STATA commands of the exposed tests and methods. Further, an empirical example is provided along with the utilized STATA codes. In the end, this article serves as a 'toolkit' allowing scholars not only to understand whether endogeneity is present in their empirical setting, but also to assess the empirical validity of their work when using instrumental variables

Creativity and E-Advertising: A Qualitative Study of Art Directors' Creative Processes

Mots clés : Créativité, Publicité, Création publicitaire

An interpretive analysis of qualitative interviews with 33 creators of advertising banners for the Internet, combined with retrospective protocols on the creation process, reveals that they hold implicit theories about the potential impact of their work on different audiences. These audiences intervene in the form of intraindividual imaginary dialogue partners who, throughout the creative process, give their reactions to the message being created. Creation and evaluation are therefore intertwined and not, as the literature on creativity has suggested, two sequential steps of the creative process

Critical Practices in Organizations

Départements : Comptabilité et Contrôle de Gestion

This article deals with the phenomenon of criticism in organizations. Existing organizational literature, where it has addressed criticism, mostly tends to see it as an extraordinary phenomenon. By contrast, in this article, the authors argue that criticism may also originate from strongly embedded and more ordinary practices. Thus, there is a theoretical need for considering those critical practices that are structurally and/or formally institutionalized within the organization. They reflect the organizational status quo and promote a reproduction of existing structures of power/knowledge. Drawing on ideas from practice theory, institutional theory, and Foucault's analytics of power/knowledge regimes, the authors introduce a typology that distinguishes forms of criticism according to the degree to which they are coupled with particular organizational practices, their rationalities, and corresponding power relations. They then focus on those forms of criticism that are strongly linked to organizational practices and illustrate the ambiguous effects of such an "organization of criticism."

Cross-cultural adjustment of expatriates in Japan


The International Journal of Human Resource Management

septembre 2008, vol. 19, n°9, pp.1588-1606

Départements : Management et Ressources Humaines

This study examines determinants of expatriate cross-cultural adjustment related to non- work (interaction and general living adjustment) and work (work adjustment and job satisfaction) aspects in Japan. It was hypothesized that cultural distance and expatriate gender, language proficiency, type (organizational or self-initiated expatriates), and stable personality traits (social initiative, emotional stability, cultural empathy, flexibility, and open-mindedness) have an influence on both non-work- and work-related adjustment. Hierarchical regression analyses, performed on data from 110 expatriates, indicate that expatriate language proficiency, type, and the personality traits of emotional stability and cultural empathy have a positive influence on both types of adjustment. Implications of these findings for practice are discussed. Keywords: Cross-Cultural Adjustment; Japan; Job Satisfaction; Multicultural Personality Questionnaire; Organizational Expatriates; Self-Initiated Expatriates

Older adults constitute a rapidly growing demographic segment, but stereotypes persist about their consumer behavior. Thus, a more considered understanding of age-associated changes in decision making and choices is required. Our underlying theoretical model suggests that age-associated changes in cognition, affect, and goals interact to differentiate older consumers' decision-making processes, brand choices, and habits from those of younger adults. We first review literature on stereotypes about the elderly and then turn to an analysis of age differences in the inputs (cognition, affect, and goals) and outputs (decisions, brand choices, and habits) of the choice process. Keywords: older consumers, decision making, choice

Discounted and finitely repeated minority games with public signals

We consider a repeated game where at each stage players simultaneously choose one of the two rooms. The players who choose the less crowded room are rewarded with one euro. The players in the same room do not recognize each other, and between the stages only the current majority room is publicly announced, hence the game has imperfect public monitoring. An undiscounted version of this game was considered by Renault et al. [Renault, J., Scarlatti, S., Scarsini, M., 2005. A folk theorem for minority games. Games Econom. Behav. 53 (2), 208–230], who proved a folk theorem. Here we consider a discounted version and a finitely repeated version of the game, and we strengthen our previous result by showing that the set of equilibrium payoffs Hausdorff-converges to the feasible set as either the discount factor goes to one or the number of repetition goes to infinity. We show that the set of public equilibria for this game is strictly smaller than the set of private equilibria
