st: missing data?

Hi all,

would you mind giving me your suggestions about the following problem?

I have 2 different Db (it means also two different survey for the same years):
Db A) there are several variables on economic strain (i.e. do you have
a pc? yes/ no, I can't afford it/ no, other reasons).
Db B) there are the same variables, but different categories (i.e. do
you have a pc? yes/ no).

Both the two Db collect information for the same country and regions.

On the one hand I would use the second Db (B) because it is the only
one that allow me to use the regional information in the longitudinal
database (while in the Db A I have the regional information only in
the cross-sectional one).

On the other hand, I would like to be able to differentiate those that
have not a specific good because they can't affort it from those that
haven't a specific good for other reason.

Do you think that appending the two Db (A and B) I can estimate these
values for the Db B such as in a missing data case?

Hope it is clear.

Thanks a million,
