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}
