Variables for employment
I am trying to understand what is the best variable to use in order to understand if a person is employed.
I found two variables that seem helpful, but I have a few questions about them:
1) The variable employ: this variable seems to be useful, but I don't understand what the "proxy" values (-7) are, and why in Wave 3 there are different interpretations for the values 1 and 2 (in the indresp datasets).
2) The second variable that seem to work is jbsemp (employee or self-employed), but can I be sure that if a person has a value of -8 (inapplicable) it necessarily means that he/she is unemployed?
One final question, can this information (employed/unemployed) be derived directly from variables for working hours or income (such as jbhrs or paygu_dv) using the inapplicable values (-8)?
Thank you very much!
