Describe the market failures that could have led to the problem nowadays and which market failures the policy you proposed addressed. If you still believe that your proposed policy change is the best way to improve societal outcomes in the realm of your original topic, describe how you would design an evaluation to test the effectiveness of the policy change you described. If, on the other hand, you no longer believe that the policy change you described would be the best thing to do, describe what has changed in your understanding of this topic and what you would now suggest doing to improve policy around your original topic and why, as well as how you would evaluate the new policy or program you are suggesting.
