Outline of Research at the Start |
1. provide new definitions of main equilibrium concepts: subgame perfect, perfect, sequential equilibrium, and quasi-perfect equilibrium that are suitable for the games without perfect recall; 2. formulate and prove series of theorems that describe properties of the newly define concepts: their existence and relationships among them; 3. investigate the implications of the theoretical findings for decision-making in situations when agents do not have perfect recall: what is the optimal way of making sequential strategic decisions when full information about the past is not available.

Outline of Annual Research Achievements |
The revised version of the second paper (Reexamination of the equivalence of strategies) was presented at the invited seminars at Cardiff Business School, Maastricht University, University of Lausanne and University of Zurich. It was also accepted for presentation at 18th European Conference on Game Theory (University of Messina). The revised version are to be soon submitted for review to Games and Economic Behaviour. The draft of the third paper (Backward Induction in Nonlinear Games, joint with Professor John Hillas, University of Auckland) was completed.

Current Status of Research Progress |
Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Dmitriy Kvasov is on sabbatical leave at University of Maastricht. Organizational issues due to temporary re-location to Europe slightly delayed the planned work on the project.
|
Strategy for Future Research Activity |
The second paper (Reexamination of the equivalence of strategies) to be prepared for publication (based on the results of peer review). The third paper (Backward Induction in Nonlinear Games) to be submitted for review at Games and Economic Behaviour.
