I am using biblatex with biber as backend and natbib loaded. What I am trying to achieve is appending an author's name with 's, e.g. in a situation like:
[...] as outlined in Krugman's (1989) early work
I could use \citeauthor{krugman89}'s (\citeyear{krugman89}), I suppose, but I was wondering whether there is a more direct way of appending the 's directly to the author's name. \citet[]['s]{krugman89} would not work, since this adds the 's after year in parenthesis, i.e. Krugman (1989, 's).
\newcommand\posscite[1]{\citeauthor{#1}'s (\citeyear{#1})}and a more complex and deep one which really fixes the problem. – ppr Apr 30 '14 at 15:03
