Labour Training Evaluation Data
These data are pertinent to an investigation of the way that
earnings changed, between 1974-1975 and 1978, in the absence
of training. The data frame combines data for the experimental treatment
group (NSW, 185 observations), using as control data results from the PSID
(Panel Study of Income Dynamics) study (128 observations). The latter
were chosen to mimic the characteristics of the NSW training
and control groups. These are a subset of the nsw74psid1 data.
