Better Together: Using Meta-Analysis to Explore Complementarities between Ecological and Institutional Theories of Organization:

Abstract: While sharing intellectual ancestry, organizational ecology and institutionalism are rarely used conjointly to explain population dynamics. A rapprochement would nevertheless be fruitful, as the parsimonious models developed by ecologists are better able to explain organizational founding and failure when enriched with institutional variables. We present a meta-analysis of density dependence theory, which predicts a non-monotonic relationship between population density and organizational vital events. We show that ecology and institutionalism are ‘better together’ by extending this ecological framework in four institutionalism-inspired ways. First, we show that the effects of density on organizational vital rates are moderated by two conceptions of time: ecological ‘clocks’ and institutional ‘eras’. Second, we argue that the socio-political legitimacy of organizational forms, a concept with strong institutional roots, exacerbates density-related founding while attenuating failure. Third, we illustrate how...

Systèmes de contrôle interactifs et théories de l'apprentissage : une relecture des travaux de R. Simons à l'aune des théories piagétiennes

Abstract: Resume Depuis ses articles fondateurs, les travaux de Simons ont ete largement cites dans la litterature en controle de gestion. Notamment, une litterature qui s’interesse aux liens entre strategie, controle et performance utilise comme cadre de reference la typologie des systemes de controle (diagnostique-interactif ). L’utilisation des travaux du chercheur nous semble toutefois limitee, car chez Simons, les systemes de controle sont structurants de l’apprentissage managerial. Nous nous appuyons sur une theorie structuraliste en psychologie cognitive, (Piaget, 1930, 1931, 1934, 1935, 1949, 1966, 1968), pour proposer une analyse de contenu des travaux de Simons (1987, 1990, 1991, 1994, 1995, 2000), organisee autour de quatre thematiques tirees de notre lecture de Piaget : le role du langage des outils de controle, l’interactivite des systemes de controle, le lien entre strategie et controle, et enfin l’integration de l’incertitude dans les systemes de controle. Au-dela, nous cherchons a mettre en avant les apports de la pensee piagetienne pour l’ensemble du champ du controle, en questionnant dans quelle mesure la disciplinarisation-structure du controle, et de ses outils, est aussi source d’emancipation, donc de production de connaissances.

Insiders-Outsiders, Transparency and the Value of the Ticker !

Abstract: We consider a multi-period rational expectations model in which risk-averse investors dier in their information on past transaction prices (the ticker). Some investors (insiders) observe prices in real-time whereas other investors (outsiders) observe prices with a delay. As prices are informative about the asset payo¤, insiders get a strictly larger expected utility than outsiders. Yet, information acquisition by one investor exerts a negative externality on other in- vestors. Thus, investors'average welfare is maximal when access to price infor- mation is rationed. We show that a market for price information can implement the fraction of insiders that maximizes investors'average welfare. This market features a high price to curb excessive acquisition of ticker information.We also show that informational e¢ ciency is greater when the dissemination of ticker information is broader and more timely.
