Leadership & Organizational Behavior

Firms are increasingly seeking to harness the potential of social networks for marketing purposes. Therefore, marketers are interested in understanding the antecedents and consequences of relationship formation within networks and in predicting interactivity among users. The authors develop an integrated statistical framework for simultaneously modeling the connectivity structure of multiple relationships of different types on a common set of actors.

Power and choice represent two fundamental forces that govern human behavior. Scholars have largely treated power as an interpersonal construct involving control over other individuals, whereas choice has largely been treated as an intrapersonal construct that concerns the ability to select a preferred course of action. Although these constructs have historically been studied separately, we propose that they share a common foundation — that both are rooted in an individual's sense of personal control.

The ability of humans to display bodily expressions that contradict mental states is an important developmental adaptation. The authors propose that mind-body dissonance, which occurs when bodily displayed expressions contradict mentally experienced states, signals that the environment is unusual and that boundaries of cognitive categories should be expanded to embrace atypical exemplars. Four experiments found that mind-body dissonance increases a sense of incoherence and leads to category expansion.

Theories of visionary leadership propose that groups bestow leadership on exceptional group members. In contrast, social identity perspectives claim that leadership arises, in part, from a person's ability to be seen as representative of the group. Integrating these perspectives, the authors propose that effective leaders often share group members' perspectives concerning the present, yet offer a unique and compelling vision for the group's future.

Scarcity has long been known to impact consumers' choices. Yet, the impact of shelf-based scarcity in retail environments, created by stocking level depletion, has received almost no attention in the literature. Indeed, little research to date has even examined if consumers will attend to shelf-based scarcity in retail environments, much less how this cue can impact choice. A priori, given the inherently noisy and cue-filled nature of retail environments, it is quite reasonable to expect that shelf-based scarcity would play little to no role in consumers' choices.

Contingent capital, a regulatory debt that must convert into common equity when a bank's equity value falls below a specified threshold (a trigger), does not in general lead to a unique equilibrium in the prices of the bank's equity and contingent capital. Multiplicity or absence of equilibrium arises because economic agents are not allowed to choose a conversion policy in their best interests. The lack of unique equilibrium introduces the potential for price manipulation, market uncertainty, inefficient capital allocation, and unreliability of conversion.

Extant research recognizes that firms exploit regulatory variations to their advantage but depicts such regulatory arbitrage as a dyadic process between firms and regulators. We extend this account by including the political rivals of a firm and suggest that firms view regulatory differences as part of a corporate political opportunity structure, and exploit regulatory variations to disadvantage their rivals. Empirically, we focus on variations in right-to-work (RTW) laws which signal the pro-business climate in a state and exist in twenty-two of the 50 American states.

Historical studies reveal how organizational markets supplied artifacts that became fashionable because they met not only consumers' cultural tastes, but also their technological preferences. This article calls such artifacts cultural-technological fusions. The digital mode of production tends to generate more types of fashionable fusions, which replace each other at a growing rate, and travel increasingly swiftly across consumers globally.

Research examining both the organizing and activating effects of testosterone in one-shot bargaining contexts has been vexed by inconsistencies. Some research finds that high-testosterone men are more likely to reject unfair offers in an ultimatum game and exogenous administration of testosterone to men leads to less generous offers. In contrast, other research finds that higher prenatal exposure to testosterone predicts more generous dictator game offers and administering testosterone to women leads to more generous ultimatum game offers.
