PSID1982 is the cross-section for the year 1982 taken from a larger panel data set
PSID7682 for the years 1976–1982, originating from Cornwell and Rupert (1988).
Baltagi (2002) just uses the 1982 cross-section; hence PSID1982 is available as a
standalone data set because it was included in AER prior to the availability of the
full PSID7682 panel version.
The data is from Baltagi (2002).
