# Make section and subsection titles similar to journal

I would like to make the titles of the sections of my paper and subtitles, have the same formatting as the American Economic Review. Here's an example:

The section titles should be centered, start with I, II, III, and subsections with A, B, C ...

While they do provide a .cls class, I cannot figure out which lines I should put in my preamble as I would like to avoid using the whole thing. Does anyone know which lines should suffice and modifications needed (if any?)

It is simple with titlesec:

\documentclass[12pt, twoside]{article}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}%
\usepackage{titlesec}%

\renewcommand{\thesection}{\Roman{section}}
\titleformat{\section}[block]{\normalsize\bfseries\filcenter}{\thesection.}{1em}{}
\titlespacing*{\section}{0pt}{11pt plus 2pt minus 2pt}{11pt plus 2pt minus 2pt}
\renewcommand{\thesubsection}{\Alph{subsection}}
\titleformat{\subsection}{\normalsize\itshape\filcenter}{\thesubsection.}{1em}{}
\titlespacing*{\subsection}{0pt}{11pt plus 2pt minus 2pt}{11pt plus 2pt minus 2pt}

\begin{document}

\section{A Delightful Section}
\lipsum[1]
\subsection{A Lovely Subsection}
\lipsum[2-3]

\end{document}


• Hi @Bernard, thanks for the reply. This is almost what I am looking for. The only thing is that if one adds another section and subsection to the text, the subsection indexing does not restart. I.e. a subsection of section II starts being numbered at B. How can I solve that? Jul 21, 2017 at 9:47
• @phdstudent: It's my fault: I copy-pasted the redefinition of \thesection to redefine \thesubsection, but forgot to change the name of the counter accordingly. The code has been fixed. Thank you for pointing it! Jul 21, 2017 at 9:58
