I’m attempting to measure job attrition from 2015 to 2016 using the variables JTOCC (occupation in 2015) and JTSAME (have you changed jobs since last year?). I get identical results for all JTOCC categories except “0000” (NA) when I switch JTSAME from “01” (not doing same job as in 2015) to “02” (doing same job). I’m unsure what to make of this.
I am not entirely certain of what you are explaining here. In any case, I can note the following. For the January 2016 sample, all observations with JTSAME==2 have JTOCC==0. Observations with JTSAME==1, JTOCC takes on all of the available occupation categories.
