%%% LaTeX class for manuscripts submitted to the
%%% European Review of Agricultural Economics (ERAE)
%%%
%%% author: Arne Henningsen
%%% version: 1.3 (18 November 2009)
%%% license: LaTeX Project Public License
%%%
%%% Note: This is an unofficial style file that may not fully comply
%%% with the ERAE Formatting Instructions in every detail.
%%% Please report any problems at
%%% http://sourceforge.net/projects/economtex/
%%% Further information is available at
%%% http://economtex.wiki.sourceforge.net/
%%%
%%% This document class is based on the "scrartcl" class
%%% from the KOMA script bundle.
%%% Following additional packages are required:
%%% amsmath, babel, courier, endfloat, geometry,
%%% helvet, ifthen, mathptmx, natbib, setspace, titlesec, url
%%%
%%% The class provides following options:
%%% noendfloat - don't move floats to the end of the paper
%%% author - show name(s) of authors(s)
%%% date - show date
%%%
%%% The ERAE requires that you use single quotes
%%% you could do this with the ``csquotes'' package:
%%% \usepackage{csquotes}
%%% \MakeInnerQuote{<yourQuoteCharacter>}
%%%
%%% The corresponding BibTeX style file "erae.bst" should be used
%%% for the bibliography: \bibliographystyle{erae}
%%%
%%% This document class provides 5 new commands:
%%% \keywords can be use to show keywors below the abstract
%%% \jelclass can be use to show JEL classifications below the abstract
%%% \affiliation can be used to add affiliation information
%%% \citetPage{page}{key} for citations like Author (Year: page)
%%% \citepPage{page}{key} for citations like (Author, year: page)
