Effects of Limited and Heterogeneous Me...

Limited memory of decision-makers is often neglected in economic models, although it is reasonable to assume that it significantly influences the models’ outcomes. The hidden-action model introduced by Holmström also includes this assumption. In delegation relationships between a principal and an agent, this model provides the optimal sharing rule for the outcome that optimizes both parties’ utilities. This paper introduces an agent-based model of the hidden-action problem that includes limitations in the cognitive capacity of contracting parties. Our analysis mainly focuses on the sensitivity of the principal’s and the agent’s utilities to the relaxed assumptions. The results indicate that the agent’s utility drops with limitations in the principal’s cognitive capacity. Also, we find that the agent’s cognitive capacity limitations affect neither his nor the principal’s utility. Thus, the agent bears all adverse effects resulting from limitations in cognitive capacity.
