Description

This data frame contains 2787 rows and 10 columns. These data are pertinent to an investigation of the way that earnings changed, between 1974-1975 and 1978, in the absence of training. Data for the experimental treatment group in nswdemo are combined with the psid1 control data from the Panel Study of Income Dynamics (PSID) study.

Details

The cps1 and psid1 data sets are two non-experimental "control" groups, alternative to that in nswdemo, used in investigating whether use of such a non-experimental control group can be satisfactory. cps2 and cps3 are subsets of cps1, designed to be better matched to the experimental data than cps1. Similary psid2 and psid3 are subsets of psid1, designed to be better matched to the experimental data than psid1. nswpsid1 combines data for the experimental treatment group in nswdemo with the psid1 control data from the Panel Study of Income Dynamics (PSID) study.
