DISCUSSION: Roughly speaking, the authors believe that:
- People migrate when their expected earnings gains exceeds the costs of migrating (lines 25-29)
- The Great Migration followed this pattern
The right answer will be consistent with this. Three of the wrong answers contradict this.
___________
- CORRECT. The authors agree with this. They think migration costs are also important. See lines 26-29.
- The authors seem to treat early migrations as unimportant. They only mention them in passing in lines 4-6, as “While there was some African American migration”.
- This contradicts the passage. In paragraph 3, the authors lay out a model of migration accepted by mosts economists: “people migrate if their expected earnings increase is large enough to compensate for the costs of migration”. (lines 26-29) Paragraph 4 shows that the Great Migration followed this pattern.
- The authors don’t believe this. Lines 23-25 show that the authors think that migration cost was also an important factor.
- This is crazy. The authors aren’t saying that the Great Migration was the first migration in world history! In fact, lines 10-11 implicitly contradict this answer by hinting that there previously had been a great migration of Europeans to the US North.
