I'm not even going to bother reading the rest of the responses, so if this has been said already, forgive me:

Go for the one that, following graduation, will be the easiest to get a well-paying job in. Something that will allow you to immediately support yourself comfortably, therefore allowing you to continue education in another field. As you said, that's Economics.

If you plan on dual-majoring, which is the impression I get... well, that's tough. Normally, I would say whatever one shares the most classes with the other. However, Economics really isn't going to have anything in common with Philosophy or Psych. I would say go with Psych. Not because I think it's necessarily better, but because if you go for Philosophy, you will have to spend a lot of time around pretentious emo kids who love to hear their own voices but can't say anything of value.
