### Model the uncertain impact of a proposed policy by expected utility or other probabilistic approach

The impact of a proposed policy is often uncertain and subjected to randomness. As such, it seems natural to use probabilistic models. How to model the policy impact using the expected utility ...

### Could Allais Paradox and similar experiments be harmonized with expected utility theory by noting additional counterparty risks?

My answers to the initial formulations of Allais Paradox are 1B and 2B, but only for setups where I have a high degree of confidence in the method of randomness being employed. In many if not most ...
