What job to do while still studying for a degree in economics?

I am currently studying part time in econs and management and would like to gain relevant job experience in economics while I am working and studying. So what type of jobs is relevant to this field?

None you can do. Jobs that require a degree in economics usually require a GRADUATE degree in economics. A possible exception is SAS programming, which you can do with an undergraduate degree.

Work as an intern or research associate at a market research firm (If you can find one -- they're not on every block).
