Abstract
Estimates of the union wage premium for US workers are presented based on longitudinal data from the 1979 cohort of the National Longitudinal Survey of Youth. Our results indicate that the long-term private-sector union wage premium for men has remained fairly steady at nearly 22% over the period 1990 to 2010. For women, the wage premium exhibits greater volatility, although no clear downward trend, and is approximately one-half of the male premium.
Notes
1 The percentage wage effect of union status is calculated as: . To avoid the specification problems discussed in Booth (Citation1995), our wage model does not correct for the endogeniety of union status.
2 For males, the union coefficient was positive, and significant at the 1% level, in all 11 wage regressions. For females, the coefficient was positive in all regressions, and significant at the 5% level, in 9 of 11 regressions. The full regression estimates are available from the authors.
