I am trying to cite a reference using the informs2014 bibliography style, but I keep getting the Undefined control sequence error when there is more than one author in a citation. MWE:

main.tex:

documentclass{scrartcl}



usepackage{natbib}



begin{document}



cite{citationkey}



bibliographystyle{informs2014}

bibliography{references}



end{document}

references.bib:

@article{citationkey,

  title={Something important},

  author={Big Guy and Another Big Guy},

  journal={Prestigious Journal},

  volume={47},

  number={7},

  pages={966--978},

  year={2001},

  publisher={Institute}

}

Errors:

Undefined control sequence. cite{citationkey}

Undefined control sequence. ... protectBIBand{} Guy(2001)}]{citationkey}

What confuses me is that I have been using the bibliography style file for a while without encountering this issue before.

As the error says, the problem is in the undefined command BIBand to be used for multiple authors citation.

In the informs2014.bst file from here we can find

FUNCTION {bbl.and}

{ "protectBIBand{}"}

and so the command BIBand is in use. So it should be defined somewhere.

In the Management-Science-template.tex file (also from here) we can find

% Natbib setup for author-year style

usepackage{natbib}

 bibpunct[, ]{(}{)}{,}{a}{}{,}%

 defbibfont{small}%

 defbibsep{smallskipamount}%

 defbibhang{24pt}%

 defnewblock{ }%

 defBIBand{and}%?

So, if you are not going to use their template, you have to copy the commands above to your preamble and everything should work and formated as expected.
