The files below are recent draft papers. Most are being prepared for submission or are under review or have just been reviewed and are being prepared for final submission. I place these here to disseminate them quickly. Comments are welcome!

Please contact me before citing any of these drafts; in most cases, it will be OK to cite these as unpublished drafts. However, I may have improved versions, which I can make available.

Caveat: by its very nature, this is not a well-organized set of papers. You might notice that there are multiple versions of some papers, because I happened to drop them in here at different times and didn't come up with the same file name :-). Some papers may even have better versions among my accepted papers, which are linked in from my main papers page.
