  • This article examines whether diversification destroys value by using recent econometric techniques for causal inference. It is argued that assessing whether diversification creates or destroys value is a particular case of the "treatment effects" literature that seeks to establish causation from non-experimental data. To address the diversification question, 3 different treatment effects estimators are used: the matching estimators of Dehejia and Wahba, Abadie and Imbens, and Heckman's 2-stage method. Their performance is compared in this setting. The value effect of diversification is estimated by matching diversifying and single-segment firms on their propensity score - the predicted values from a probit model of the propensity to diversify. It is found that on average, diversificati...

  • The present study examines the application of Resource Dependence Theory and Institutional Theory relative to company involvement in an important voluntary, governmentally sanctioned employee safety program that goes by the acronym VPP. Utilizing this combined theory approach, the study empirically demonstrates, through a design incorporating correlation and multiple regression analysis, that Institutional Theory is useful for predicting program prevalence within a given industry, though Resource Dependence Theory complements the former by offering an accounting of strategic firm behavior. Companies consider adoption of beyond compliance safety programs as a strategy to manage the expression of resource control power on the part of powerful stakeholders, while Institutional Theory helps...

  • The federal rules of civil procedure were intended by their drafters to be a model for states to adopt, thereby promoting national procedural uniformity. This Article proposes that the next great wave of procedural reform in American civil justice emanate from the states themselves in the form of a national code of state civil procedure. The willingness of states to chart their own paths toward civil justice reform presents both a problem and an opportunity. A central thesis of the Article is that national procedural uniformity among state courts remains a desirable, viable, and achievable goal despite the failure of the top-down federal-rules-model approach to achieve that goal. The momentum for developing uniform state procedural rules must, however, originate with the states themselv...

  • Trust at the interpersonal level in organizational settings has been researched extensively, yet little has been learned about the process through which trust affects cooperation and of the role of the social context in this process. Further, the models most often cited are complex and difficult to operationalize. This study investigates the effects of trust, subjective norms, and intent to cooperate on cooperative behavior using a simplified model. The findings demonstrate that the simplified model is useful for understanding the link between trust and cooperation and underscore the importance of perceived norms in the process. Implications for management are discussed.
