Economics PhD credentials

[shuu]

I've just got my bachelor in economics with a minor in math. I wanted to apply for Masters Econ first then PhD but my profs (also my recommenders) stongly suggested I applied directly to PhD, saying that I'm qualified already. However, I applied to 20 schools and got none acceptance. So I want to have some questions, hope you guys can answer. My qualifications are:

1. GRE quant 168, verbal 152, AW 4.5

2. Real analysis, diff. equations, linear algebra, probability stat, math econ, inter micro + macro, multivariate calculus

3. honors student with 4.0 GPA

4. award for "outstanding undergrad paper" in my uni (my thesis)

5. recommenders include a dean and a prof that has broad connection

No research experience as a research assistant, as I'm undergrad. No published paper. State school bachelor. But i believe no under students can publish paper or have research exp.

and a few more small things. I applied from top schools to less known programs like U Washington seattle, george washington U, penn state, U illinois urbana. Can you guys please help me point out what I lack seriously so that i got none acceptance? Am I that unqualified or others are too good?

Thanks a lot
