Your bibliography example doesn't contain any year data, but I'm assuming you're using the authortitle style (or one of its variants). Also note that shorttitle and shorthand are distinctive fields.
\documentclass{article}
\usepackage[style=authortitle]{biblatex}
\renewbibmacro*{finentry}{%
\finentry
\addspace
\mkbibemph{\printtext[brackets]{\usebibmacro{cite}}}%
}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{Bli74,
author = {Blinder, Alan S.},
year = {1974},
title = {The economics of brushing teeth},
shorttitle = {Brushing teeth},
journaltitle = {Journal of Political Economy},
volume = {82},
number = {4},
pages = {887--891},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\textheight=120pt% just for the example
\begin{document}
Some text \autocite{Bli74}.
\printbibliography
\end{document}
