Ambiguity vs. mixed strategies in multi-agent ambiguous contracts

Determine whether, in multi-agent settings, allowing agents to play mixed strategies still eliminates the principal’s advantage from employing ambiguous contracts.

Background

The survey establishes that in single-agent settings, mixed strategies completely remove the power of ambiguity. It explicitly raises the question of whether this phenomenon persists in multi-agent environments, where ambiguity interacts with strategic complexity.

A resolution would clarify the role of ambiguity in multi-agent contracting and guide the design of commitment mechanisms in richer strategic contexts.
