AJAE standard references in Latex and Puthesis

The package economic has a bibliography style based on AJAE standards:
The package is at:
http://www.ctan.org/tex-archive/biblio/bibtex/contrib/economic/
and should be easy to install using mike/live tex standard installers.
To use it with puthesis, add this line to puthesis.cls (I added it where all the bib styles are defined, I do not know if that matters):
\DeclareOption{ajae}{\set@@optionbibstyle{ajae}}.
Then, declare it in the document class:
\documentclass[agecon,ajae,dissertation]{puthesis} (thanks Todd for this hint) and be sure to declare it as bib style in the bibliography section:
\bibliographystyle{ajae}.
