The effect is important if you have text and equations.
This is an example of latex code:

\documentclass{article}\pagestyle{empty}
\textwidth 6 cm
\begin{document}
\noindent
In the stationary regime:
$\sum_j J_{j\to i}^{st}=0$
\end{document}

The \texwidth option determines the location of the equation with respect to
the text. The reason is that the text is always left-justified, whereas the
equation is centred with respect to \textwidth. If you increase \textwidth
the equation moves to the right.
