The Minimum Wage and the Employment of Youth Evidence from the NLSY
利用美国青年纵向调查的面板数据，发现1979和1980年联邦最低工资上调后，受影响的在职者一年后就业概率降低约3%，即使考虑了不可观测的个体差异。
Using panel data on individuals from the National Longitudinal Survey of Youth, we find that employed individuals who were affected by the increases in the federal minimum wage in 1979 and 1980 were about 3 percent less likely to be employed a year later, even after accounting for the fact that workers employed at the minimum wage may differ from their peers in unobserved ways.
