Acquisition Games with Partial-Asymmetric Information
# 15
Abstract
We consider an example of stochastic games with partial, asymmetric and non-classical information. We obtain relevant equilibrium policies using a new approach which allows managing the belief updates in a structured manner. Agents have access only to partial information updates, and our approach is to consider optimal open loop control until the information update. The agents continuously control the rates of their Poisson search clocks to acquire the locks, the agent to get all the locks before others would get reward one. However, the agents have no information about the acquisition status of others and will incur a cost proportional to their rate process. We solved the problem for the case with two agents and many locks and conjectured the results for N-agents. We showed that a pair of (partial) state dependent time-threshold policies form a Nash equilibrium. We further obtained good structural properties of the thresholds.
