Dear IJEP authors and readers, unfortunately due to a server and OJS
software failure our journal's website has fatally crashed. We are
trying to bring it back. Our website will be restored in a couple weeks.
We are terribly sorry for the inconvenience caused. Even though it has
some missing articles in it, Journal's
other web page is active and running.
Meanwhile you may find what you're looking for in there.
Thank you for your patience.
