Details

The data were originally analyzed by Cornwell and Rupert (1988) and employed for assessing various instrumental-variable estimators for panel models (including the Hausman-Taylor model). Baltagi and Khanti-Akom (1990) reanalyzed the data, made corrections to the data and also suggest modeling with a different set of instruments.

PSID7682 is the version of the data as provided by Baltagi (2005), or Greene (2008).

Baltagi (2002) just uses the cross-section for the year 1982, i.e., subset(PSID7682, year == "1982"). This is also available as a standalone data set PSID1982 because it was included in AER prior to the availability of the full PSID7682 panel version.
