Optimal contracting with predecision information: Communication problems under pure asymmetry of information

The purpose of this dissertation is to extend the communication model to a situation where the agent searches for pre-decision information with effort in his own self-interest. We first introduce the agency model that involves the agent's information-searching behavior, the choice of information system, in the economic setting of pure asymmetric information where the principal cannot observe either the agent's information system or information-searching effort.
