What is ex ante policy analysis?
Ex-ante Policy Impact Assessment (hereafter PIA)1 is an analytical process, conducted at the early stages of policy-making exercise.

How do you calculate ex-ante?
Ex ante variance calculation:
- The expected return is subtracted from the return within each state of nature; this difference is then squared.
- Each squared difference is multiplied by the probability of the state of nature.
- These weighted squared terms are then summed together.
What is the difference between ex post and ex-ante?
