It is already done today. Academic panels, economists writing papers on impacts of various policies like rent control, monetary policy, and yes, taxes. Are some of them politically motivated or have academic disagreements? Sure, all people have personal politics and biases. But that is better than throwing up ones hands and saying we should accept all bad taxes because good ones also exist. By that logic, any tax I suggest should be accepted by you, because there is no way to tell if it's good or bad right?
