is the measure economically efficient, or is there a better alternative policy?
This question depends on the specific measure being discussed. In general, determining the economic efficiency of a policy measure involves assessing whether it helps to achieve the desired outcome at the lowest cost possible.
If the measure is deemed to be economically efficient, then there may not be a better alternative policy. However, if the measure is considered to be economically inefficient, then it is worth exploring alternative policies that could achieve the same goal more cost-effectively.
Ultimately, the best alternative policy will depend on the specific context and goals of the measure in question. It may be helpful to conduct a cost-benefit analysis or seek input from experts in the field to determine the most economically efficient approach.
