The Border Study That Challenged Minimum-Wage Orthodoxy
Krueger recounts his study with David Card comparing fast-food employment in New Jersey and Pennsylvania after New Jersey increased its minimum wage. Contrary to their initial expectation, affected restaurants did not grow more slowly, helping redirect subsequent minimum-wage research.
- The researchers expected slower restaurant growth
- New Jersey restaurants grew at least as much as comparison restaurants
- Within-state comparisons produced a similar result
- Later studies using government records often reached the same conclusion
“and in fact we saw the opposite.”
“I think that study was a turning point in research on the minimum wage.”
