% AER.STY (for LaTeX2e)
%
LaTeX style file for typesetting papers in the style of the American Economic Review
% By Martin J. Osborne (osborne@chass.utoronto.ca)
% 97/10/16; revised 99/5/10
% load after article.cls
% load also amstex package, with leqno option
% Close to AER journal style (but not 2 column!!)
% Difference with MJOARTI.STY: Theorems, lemmas etc. are numbered separately
% and are in AER style. Use Atheorem, Aproposition, etc. for theorems etc.
% in the Appendix (so that they will be numbered A1, A2, and so on.
% At start of Appendix, put
% \renewcommand{\theequation}{A\arabic{equation}}\setcounter{equation}{0}%
% (so that equations are numbered (A1), (A2), ...
% (Could put this as part of an \appendix macro.)
% Sections are numbered differently and their titles formatted differently.
