The string "Absent" cannot be converted to an integer, obviously.

It doesn't work because it isn't written in the correct mode.
You have to write in the right mode as this way:

select case when economics ='-1' then 'Absent'
else Economics end as Economics
from tblCOM

or in you case
select replace(economics,'-1','Absent') as Economics
from tblCOM
