The Border Study That Changed Minimum-Wage Research
Krueger recounts his study with David Card comparing fast-food employment in New Jersey and Pennsylvania after New Jersey raised its minimum wage. Contrary to their expectation, restaurants exposed to the increase did not grow more slowly, and subsequent studies using other data reached similar conclusions at historically modest wage levels.
- The researchers initially expected slower restaurant growth
- New Jersey restaurants grew at least as much as comparison restaurants
- Within-state evidence pointed in the same direction
- Later research broadly replicated the employment finding
“And in fact we saw the opposite.”
“minimum wage increases do not have an adverse effect on employment.”
