Answer:
This is the rest of the question:
Crystal: You really think households would change their saving behavior enough in response to this to make a difference? Because I don't.
The disagreement between these economists is most likely due to _____
Explanation:
The answer is that their disagreement is most likely due to differences in scientific judgments of normative statements.
Normative statements are those that tell us "what ought to be", that recommend something. In this case, Crystal and Brian disagree whether an income tax or a consumption tax influences saving behaviour more. They are economists who have differing scientifc views on the possible effects of both types of taxes.
