An interesting paper (in PDF format):
The Economic Thought of Abu Hamid al-Ghazali and St. Thomas Aquinas: Some Comparative Parallels and Links, from the
History of Political Economy journal. It's a worthwhile read, although philosophically trained readers will experience the usual frustrations with papers on the history of philosophy written by historians: the odd tendency to cite extensively what other historians say about the texts, the failure to analyze arguments into their component parts, etc. But patience pays off here as elsewhere. I'm not really sure what the author was thinking citing Durant as a source on scholasticism, though.
