%%% Note: This is an unofficial style file that may not fully comply
%%% with the Formatting Instructions of the "Regional Studies" in every detail.

%%%
%%% This document class is based on the "scrartcl" class
%%% from the KOMA script bundle.
%%% Following additional packages are required:
%%% amsmath, babel, endfloat, endnotes, fontnec, geometry,
%%% ifthen, natbib, setspace, soul, titlesec, url, verbatim
%%%
%%% The corresponding BibTeX style file "regstud.bst" should be used
%%% for the bibliography: \bibliographystyle{regstud}
%%%
%%% The document class provides following options:
%%% noendfloat - don't move floats to the end of the paper
%%% hidefloats - hide all floats (figures and tables)
%%% author - show name(s) of authors(s)
%%% date - show date
%%%
%%% This document class provides 3 new commands:
%%% \keywords can be used to show keywors below the abstract
%%% \jelclass can be used to show JEL classifications below the abstract
%%% \affiliation can be used spefify the affiliation(s) of the author(s)
%%%
%%% If you use footnotes, add following line before the reference section:
%%%    \listofendnotes
%%%
%%% "Regional Studies" requires that you use single quotes
%%% you could do this with the ``csquotes'' package:
%%% \usepackage{csquotes}
%%% \MakeInnerQuote{<yourQuoteCharacter>}
%%%
%%% To prepare a manuscript without floats, you can use
%%% either option "hidefloats" to hide all floats
%%% or extract the pages that do not include the floats
%%% with "pdftk", e.g. "pdftk all.pdf cat 1-14 output main.pdf"
%%% The former has the drawback that references to the hidden floats
%%% with \ref{} are no longer possible.
%%% The figures and tables can be extracted as images, e.g. with kpdf.
