Çoklu ajanlı ortamlarda iletişim ve karar haklarının dağıtımı

In many economic environments such as multidivisional organizations, principals have to resolve the conflict between coordinating the decisions of self interested agents and successfully adapting to local conditions. We model the interdependencies that require coordination as complementarities (or substitutabilities) and (positive or negative) externalities between actions taken by these agents. Also, each agent has private knowledge of local conditions that the organization should adapt to. We consider centralization and decentralization as two alternative regimes of communication and decision making. Under centralization, agents send simultaneous signals about their private information to the principal who then decides on actions, while under decentralization, agents communicate with each other prior to taking actions on their own. In this paper we provide an analysis of strategic communication in these two regimes. We also investigate which regime is optimal (efficient) in different organizations. In both regimes, the quality of communication varies with the nature of the interaction between complementarities and externalities. In the decentralized regime, the extent of informative communication is very limited, while the centralized one allows for more informative communication. In particular, complementarities and positive externalities result in no information being transmitted under decentralization. We also show how the informativeness of communication influences the e fficiency of diff erent regimes.Keywords: Cheap Talk, Decision Rights, Incomplete Contracts, Organizational Strategy, Strategic Complements, Strategic Substitutes, Externalities.
