Work Group Competition and Performance Dynamics.

Besides consultants and practitioners, some contributions in the organizational economics literature have advocated substituting internal firms' bureaucracies with markets to regulate internal transactions. However, usually the effects of competition on performance are considered in terms competition across firms or industries. By contrast, other contributions point out that competition is pervasive inside firms as well.

Nonlinear dynamics in work groups with Bion's basic assumptions.

According to several authors Bion's contribution has been a landmark in the thought and conceptualization of the unconscious functioning of human beings in groups. We provide a mathematical model of group behavior in which heterogeneous members may behave as if shared to different degrees what in Bion's theory is a common basic assumption. Our formalization combines both individual characteristics and group dynamics.

Personnel turnover in organizations: an agent-based simulation model.

We study how personnel turnover policies may affect the global behavior of a simple model of organization. In the model we propose, heterogeneous agents interact dynamically, adapting their effort level. Effort equilibria in populations consisting of both perfectly rational and bounded-rational agents are considered.
