Wooldridge Source: F. Vella and M. Verbeek (1998), “Whose Wages Do Unions Raise? A Dynamic Model of Unionism and Wage Rate Determination for Young Men,” Journal of Applied Econometrics 13, 163-183. I obtained the data from the Journal of Applied Econometrics data archive at http://qed.econ.queensu.ca/jae/. This is generally a nice resource for undergraduates looking to replicate or extend a published study. Data loads lazily.
