I have been trying to obtain Harsanyi (1967-68), but what I got is Harsanyi (7 68) which is last 4 digits of year item in bibliography except ''-''. Here is my MWP and bibitem, thanks for any help in advance.

\documentclass{article}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}

@article{harsanyi67,
title = {Games with Incomplete Information Played by Bayesian Players,{Parts I,II,III}},
author = {John C. Harsanyi},
year = {1967-68},
journal = {Management Science},
volume = {14},
pages = {159--182, 320--334, 486--502},
}

\end{filecontents}

\usepackage{natbib}

\begin{document}

\cite{harsanyi67}

\bibliographystyle{apalike}
\bibliography{\jobname}

\end{document}

• I don't think that it will help, but could you try year = {{1967-68}}? – Karlo Mar 14 '16 at 16:23
