Williams College: Econ/Pysch Major or Econ/Math Major

So I am interested in pursuing management consulting or investment banking after undergrad. I just got accepted to Williams and am deciding to pair my economics major with psychology or math.

I think psychology is a subject that I would enjoy more while keeping my GPA higher than it would be if I pursued math. I fear that psychology is seen as a soft subject that adds little value to an economics degree (behavioral economics?), while math would potentially bolster my analytical skills. I've heard that you don't need high-level math for either of these careers so it may be a waste of time.

As a hypothetical employer, which combination would you find most valuable and why? Maybe the minor/concentration doesn't matter as long as I majored in economics? Please let me know. I'm having a very difficult weighing the pros and cons of each. Thanks!
