The lookup problem is one I often run into in Stata. That is, retrieving a value for a variable using a (unique!) identifier from another.

One solution I have used is to store the variable of interest in a matrix. If (!) your ID is a unique string, then you can

  mkmat education, matrix(E) rownames(ID)
  gen motheredu= el("E",rownumb("E",motherID),1)

Hello everyone.
I am dealing with a big household survey.
I am interested in child labor and education and my objective is to create variables for each children representing parents or household' characteristics.
In particular, for each children I created two variables specifying the IDs of mother and father. Now I would like to create a  variable that, for each children, specifies parents' education in the following way

motheredu_i=education[motherID_i]

where education is a variable already in the dataset

I know a way to do this, but it is extremely time consuming and I was wondering what would be the syntax to create the above "function".

Thanks.
