Your claim is quite incorrect. There is detailed documentation on
handling dates and your problem is included. The main help on dates
and times points you to the function -ym()- which can be used to
combine year and month values. For example,
. di %tm ym(2012,1)
2012m1
In your case you appear to need
. gen monthlydate = ym(var1, var2)
I don't understand what you mean by needing to use lags for this
problem. But note that in Stata "merging" overwhelmingly tends to mean
using -merge- to combine entire datasets.
