shooting for a phd in business

[gregoryhouse]

I could really use some help here, I'm having quite a headache in making choices.

So I studied psych for undegrad with a specialization in stat. Now the new plan is, instead of going to one of the psych phd programs I've been accepted, to get into a phd program in business - psych related fields such as management or marketing. Reasons including: likely more money; more flexible career options. I have been accepted to applied math, applied stat, and a masters in econ as well, so the questions are:

1) would applied stat/math be more useful in getting me admitted AND laying a good foundation to complete PhD degree in biz than the ma degree in econ?

2) but which one, applied stat or applied math? as far as I know (after checking out a couple b-school phd course requirments and hearing from ppl in some of those programs), it seems phd in management/marketing requires mostly stat not math, while operation research/finance(/maybe acc?) requires more math. So in my case, I should be going to applied stat undoubtedly?

3) which is harder? I personally found 100-200 undergrad math more comprehensible than 200 or up stat (don't have 100 level stat here), but maybe that's a result of not taking theoretical courses on stat and jumping to the applied part (which makes stat no more meaningful than bunch of tests)? Never taken anything higher than 200 in math and no higher than 300 in stat so don't know what the trend is gonna be like for me. But most ppl I asked went for "the higher, math is harder for sure".

4) do anyone know anything about phd in biz? i heard there's shortage of biz professors in these years but more and more ppl are going in for phd in biz and there's at least 5 yrs ahead before I'll be on the market, maybe then there's gonna be a surplus?

I appreciate any inputs/insights !! Enlighten me!

Just realized we actually have a biz forum here right after I finished posting. I probably should've checked there before I ask in here. But still, you guys know the math and stat stuff!
