Card and Krueger show a positive correlation between an increased minimum wage and employment in New Jersey. Many others have thoroughly debunked this study and it is significant that the original authors eventually retracted their claims. 详见:

Researchers from the Employment Policies Institute also reported finding data errors in the Card and Krueger sample. In one Wendy’s in New Jersey, for example, there were no full-time workers and 30 part-time workers in February 1992. By November 1992, the restaurant had added 35 full-time workers with no change in part-timers. See David R. Henderson, “The Squabble over the Minimum Wage,” Fortune, July 8, 1996, pp. 28ff.
