labor-force status, level of education, or marital status? Given that race and gender are themselves social constructs, at least in theory they could also change over time.

I am just curious -- why would you need to take lags of anything
produced by -xi-? I usually think of the categorical variables as
something fixed, like one's race or gender.

I have created a set of vars using xi command that has resulted in
_IstXab_1 _IstXab_2, etc.

The following reference to the varlist works:

regress y _IstXab*

However, I cannot use lag or difference operators:

regress y l._IstXab*

results in error of:

_IstXab* ambiguous abbreviation
