Suppose that Nick, an economist from a university in Arizona, and Rosa, an economist from a public television program, are arguing over saving incentives. The following dialogue shows an excerpt from their debate: Rosa: I think it's safe to say that, in general, the savings rate of households in today's economy is much lower than it really needs to be to sustain an improvement in living standards.
Nick: I think a switch from the income tax to a consumption tax would bring growth in living standards.
Rosa: You really think households would change their saving behavior enough in response to this to make a difference.

1.The disagreement between these economists is most likely due to (differences in values, differences in perception versus reality, differences in scientific judgments) .
2. Despite their differences, with which proposition are two economists chosen at random most likely to agree?

a. Lawyers make up an excessive percentage of elected officials.
b. Minimum wage laws do more to harm low-skilled workers than help them.
