Take the following as truth: As shown in table 4.2, how much the couple's $4,000 annual contribution adds to national saving that year depends on (1) how much their IRA tax deduction costs the government and (2) whether their contributions represent new saving or were shifted from existing assets.
Then the following statement: "The table shows how national saving is impacted by the couple's contribution to their Roth IRA." is true, false, or inconclusive?
Answer: Inconclusive
