I use the natbib package for my work and all my citations are working fine, except this one:

author    = {Tobin, James},
title     = {Liquidity Preference as Behavior Toward Risk},
journal   = {Review of Economic Studies},
volume   = {25},
number   = {2},
pages    = {pp. 65--86},
year      = {1958}

In the bbl this translates to:

Tobin, J.  \harvardyearleft 1958\harvardyearright , `Liquidity preference as
behavior toward risk', {\em Review of Economic Studies} {\bf 25}(2),~pp.

And the error I receive:

Package Natbib warning: citation 'tobin58' on page 5 undefined on input line 196

I think the the setting of the environment is correct as other citations do work, nevertheless I also receive 2 errors:

File ended while scanning use of \harvarditem

I get this error on line \bibliography{BibTeX1}

LaTeX Error: \begin{thebibliography} on input line 1 ended by \end{document}

I get this error on line \end{document}


\section{First Appendix}

The syntax of my citation is identical to the working ones, I really can't find any syntax errors.

Could you help me please? Do I need to provide you more information?

    A full MWE would be of great help. Of especial interest would be: How do you call natbib (options etc.)? Is there any other package that might interfere with natbib? What cite commands do you use? For what it's worth, you might want to have a look at natbib: use the harvard referencing system and har2nat.

    On another note, you should not put pp. or p. manually into the pages field, BibTeX and the like can do that for you automatically. Unfortunately, agsm uses obsolete font commands (\bf, \em), so it might not be the best choice after all.

    Welcome to TeX.SE! Given that you're using the agsm bibliography style, are you also loading the harvard citation management package? If you prefer to use the natbib citation management package instead, you should load the har2nat package as well -- and not load the harvard package at all. This point is also addressed in @moewe's comment.

It's not clear to me what the source of the error is that you're getting. Maybe it's the fact that you're using the natbib citation management package along with agsm, which is a bibliography style provide by the harvard citation management system. It's best not to mix-and-match citation management packages and bibliography styles. If you do need to use natbib and agsm, you should also load the har2nat package (but not the harvard package as well!).

Anyway, assuming that the tobin58 bibliographic entry is stored in a file called tobin58.bib, the following MWE






produces this output:

enter image description here

If you prefer, comment out the natbib-related instructions and uncomment the two harvard-related instructions. By the way, if you remove the "pp. " from the pages field of the bibliographic entry, it will also disappear from the typeset output.

Incidentally, this is what the .bbl file produced by the MWE looks like:


Tobin, J.  \harvardyearleft 1958\harvardyearright , `Liquidity preference as
  behavior toward risk', {\em Review of Economic Studies} {\bf 25}(2),~pp.
