Problemistic search theory, with its roots in the Carnegie School tradition, describes a behaviorally plausible process by which firms learn from performance feedback. A firm's recognition of performance below aspirations leads to search for a solution to the problem, resulting in change intended to restore performance to the aspired level. The concept of problemistic search has diffused broadly in the management literature-it is a central theoretical concept in a broad variety of organizational theories, and an important explanation of a wide variety of organizational behaviors and outcomes. We review the literature and argue that the development of the theory has not kept pace with the breadth of the unfolding literature. We identify six critical issues with extant research that can be traced back to a continued (over) reliance on the initial conceptualization of problemistic search. To address these issues and to revitalize research, we propose a research agenda premised on a more central role for cognition in the theory and the need for greater emphasis on a process perspective of problemistic search.

A common justification for organizational change is that the circumstances in which the organization finds itself have changed, thereby eroding the value of utilizing existing knowledge. On the surface, the claim that organizations should adapt by generating new knowledge seems obvious and compelling. However, this standard wisdom overlooks the possibility that the reward to generating new knowledge may itself be eroded if change is an ongoing property of the environment. This observation in turn suggests that environmental change is not a self-evident call for strategies of greater exploration. Indeed, under some conditions the appropriate response to environmental change is a renewed focus on exploiting existing knowledge and opportunities. We develop a computational model based on the canonical multiarmed bandit formulation of exploration and exploitation. We endeavor to understand the mechanisms by which environmental change acts to make purposeful efforts at organizational adaptation less (or more) valuable.

Approximately 80–90 percent of new firms ultimately fail. The tendency is to think of this failure as wasteful. We, however, examine whether there are economic benefits to offset the waste. We characterize three potential mechanisms through which excess entry affects market structure, firm behavior, and efficiency, then test them in the banking industry. Results indicate that failed firms generate externalities that significantly and substantially reduce industry cost. On average these benefits exceed the private costs of the entrants. Thus failure appears to be good for the economy. Copyright © 2005 John Wiley & Sons, Ltd.

We examine the power and limitations of imitation. Naive intuition may hold that the efficacy of imitation would be diminished by imperfections in copying high‐performing firms. Employing a computational model, we study the dynamics of imitation when firms are subject to bounded rationality that limits their ability to copy the market leader. We find that imperfect imitation can generate unexpectedly good outcomes for follower firms—indeed, better than the outcomes achieved if they were perfect imitators. Moreover, imperfect imitation, from time to time, enables follower firms to surpass superior firms. These findings suggest there is an adaptive role to mechanisms, such as bounded rationality, that make perfect imitation difficult. Copyright © 2012 John Wiley & Sons, Ltd.
