biblatex citation styles

Question

I'm using the biblatex-chicago package to get my references in the author-year format, but I'm struggling with the citation styles. I'm using \autocite{cite key} modified using \renewcommand*{\nameyeardelim}{\addcomma\addspace} to be able to have a citation in parenthesis after providing a data figure (e.g. "increased by 5% (UNESCO, 2012)"). But I would also like to use \textcite{cite key} to cite a paper in the fashion 'according to Nash (1950)". Instead, I'm getting 'according to Nash1950" (the cite key in bold letters).

Is \textcite not compatible with biblatex-chicago? This citation style is supposed to look like Nash (1950). I've tried removing -chicago and running again, or using the harvard style. I also found a bibliography style (a .bst file) specific to the economics field that is a customized way to achieve citations in the format Nash (1950) so I tried using \bibliographystyle{econ_aer.bst} but that didn't work either.

Please help

MWE:

\documentclass{article}

\usepackage[backend=biber]{biblatex-chicago}
\renewcommand*{\nameyeardelim}{\addcomma\addspace}
\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{UNESCO2001,
  author = {UNESCO.},
  year = {2001},
  title = {Alpha},
}

@misc{Nash1950,
  author = {Nash, D.},
  year = {1950},
  title = {Game Theory},
}

\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

According to \textcite{Nash1950}. data figure \autocite{UNESCO2001}.

\printbibliography

\end{document}

To get a author-year format just add option authordate to the call of package biblatex-chicago. If you need some (not all!) functions used in package natbib add the option natbib to the call of biblatex-chicago. Do not use option natbib=true (see manual, page 3 for explanation)! You can't use package natbib and biblatex-chicago together.

More informations to biblatex-chicago you will find in the package documentation.

With the following MWE (with a little bit pretty printing) you should get what you want:

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@misc{UNESCO2001,
  author = {UNESCO},
  year   = {2001},
  title  = {Alpha},
}
@misc{Nash1950,
  author = {Nash, D.},
  year   = {1950},
  title  = {Game Theory},
}
\end{filecontents*}


\documentclass{article}

\usepackage[%
  backend=biber
 ,authordate     % returns Nash (1950)
%,natbib         % make some functions of package natbib available
]{biblatex-chicago} % http://www.ctan.org/pkg/biblatex-chicago
\renewcommand*{\nameyeardelim}{\addcomma\addspace}
\addbibresource{\jobname.bib}


\begin{document}

According to \textcite{Nash1950}. data figure \autocite{UNESCO2001}.

\printbibliography

\end{document}

This will gave you the result:
