1961

etc...

I would like to get the data so it looks like:

yr     country   series(exports)    series(imports)
1960   1             (value)            (value)
1961   1              ""                      ""
1960   2             ""                        ""
1961  2                ""                      ""


I am new to Stata and completely at a loss as to how to accomplish this.  Any
help would be greatly appreciated.

Thanks,

This is not a case for transpose or -xpose-.

It looks as if you need to do two -reshape- steps.

-reshape- this to long form with only one content variable: what you show as value. Thus, you would end up with data looking something like this:

yr country series value
1960 1 imports (value)
1960 1 exports (value)
1960 2 imports (value)
1960 2 exports (value)
1960 3 imports (value)
1960 3 exports (value)

Then -reshape- it a second time to wide form, splitting the imports from the exports.

This is a sketchy description. You need to fill in the details, which depend on your particular variable names and types. It may help to have series as numerically coded. See -help reshape-.

Good luck.
