Hi everybody. I have two files: "texfile.tex" and "references.bib". They are attached and also copied in the bottom of the email. There is one citation. The **problem** is: the citation appears correctly in the body of the text in the PDF, but the References list is empty. However, if one changes line 14 \subsection{Top trading procedures} to \subsubject{Top trading procedures} then everything works: the citation appears correctly *and* the reference appears in the References list. I don't know why. Any ideas? Here are the files: \\---------- texfile.tex ---------- \usemodule[bib] \setupbibtex[database={./references}] \setuppublications[ refcommand=authoryear, sort=auhor] \starttext Let $X = \{h_{1}, \ldots, h_{n} \}$ and $D$ be all the unitary subsets of $X$; $N = \{1, \ldots, n\}$ and preferences given by linear orders (complete and strict rankings) over $D$. This is the housing market introduced by \cite{shapley_cores_1974}. \section{Procedures} \subsection{Top trading procedures} % \subsubject{Top trading procedures} % If we use "subsection" instead of "subsubject", the References disappear. In the classic housing assignment problem, Gale's {\em top trade cycles} (TTC) algorithm yields an efficient allocation that is in the core. \completepublications \stoptext ---------------------------------// And the BibTeX file: \\---------- references.bib ---------- @article{shapley_cores_1974, title = {On cores and indivisibility}, volume = {1}, journal = {Journal of Mathematical Economics}, author = {Lloyd Shapley and Herbert Scarf}, month = mar, year = {1974}, pages = {23--37} } ------------------------------------// -- Guilherme P. de Freitas http://www.gpfreitas.com
