Enterprise for Rewards
• Enterprising
behavior – Actions
taken to achieve a
reward.
Two Persons Dynamic Game of
Incomplete Information
•
The person himself/herself is one of the
players. The other is his/her
environment.
• Objectives:
1. Expectation maximization.
2. Risk minimization.
• Open question – are (1) and (2) mutually
independent?
