Have you considered tax? I graduated two years ago with a Major in Managerial Economics and a minor in Accounting and was able to find a job in Multistate Tax. A lot of the issue we work on (unity, instant unity, nexus) straddle the IB hemisphere. I have applied for a few jobs that focused on tax. However, I have not really had any tax-related coursework other than what is normal for finance majors, which was mainly managing taxes throughout a project when calculating NVP. I really do not know if my interests lie within that field without doing more research about it.
