Minimum Wages and Employment:
A
Case Study of the Fast-Food Industry
in New Jersey and Pennsylvania
On April 1, 1992, New Jersey's minimum wage rose from $4.25 to$5.05 per
hour. To evaluate the impact of the law we surveyed 410 fast-food restaurants in
New Jersey and eastern Pennsylvania before and after the rise. Comparisons of
employment growth at stores in New Jersey and Pennsylvania (where the
minimum wage was constant) provide simple estimates of the effect of the higher
minimum wage. We also compare employment changes at stores in New Jersey
that were initially paying high wages (above $5) to the changes at lower-wage stores. We find no indication that the rise in the minimum wage reduced employment. (JEL 530, 523) How do employers in a low-wage labor cent studies that rely on a similar compara- market respond to an increase in the mini- tive methodology have failed to detect a mum wage? The prediction from conven- negative employment effect of higher mini- tional economic theory is unambiguous: a mum wages. Analyses of the 1990-1991 in- rise in the minimum wage leads perfectly creases in the federal minimum wage competitive employers to cut employment (Lawrence F. Katz and Krueger, 1992; Card, (George J. Stigler, 1946). Although studies 1992a) and of an earlier increase in the in the 1970's based on aggregate teenage minimum wage in California (Card, 1992b) employment rates usually confirmed this find no adverse employment impact.
