Theories of orbitofrontal cortex (OFC) function have evolved substantially over the last few decades. There is now a general consensus that the OFC is important for predicting aspects of future events and for using these predictions to guide behavior. Yet the precise content of these predictions and the degree to which OFC contributes to agency contingent upon them has become contentious, with several plausible theories advocating different answers to these questions. In this review we will focus on three of these ideas - the economic value, credit assignment, and cognitive map hypotheses – describing both their successes and failures. We will propose that these failures hint at a more nuanced role for the OFC in supporting the proposed functions when an underlying model or map of the causal structures in the environment must be constructed or updated.

Firms receive profits and losses, while individuals and initiatives generally only receive awards as mediated by an organization’s accounting system and reward structure. In that sense, a firm can be considered to be a credit assignment mechanism. Three basic challenges are considered: the problem of diversity of selection criteria, the challenge of the timing of selection relative to developmental processes, and the issue of units of aggregation and selection. Selection inevitably must be made on the basis of various imperfect indicators of broader objectives. The diversity of these selection criteria is argued to be an under-appreciated facet of diversity as prior work has tended to focus attention on the degree of diversity of underlying initiatives and activities. Further, it is recognized that the environment, or contexts, in which the organization operates, is itself an object of selection, which in turn influences the feedback processes the organization experiences.
