Andrew Gelman links a paper by Christian Grose and Carrie Russell I am discussant for at SPSA in three weeks. (Incidentally, it’s the only paper for the panel I’ve received so far—but since I’m not exactly on-schedule with my paper, I can’t really throw many stones about it.)

The paper looks at the effect of being required to vote publicly (for example, in a caucus setting) on voters’ willingness to participate based on a novel experiment conducted during the 2008 Iowa Democratic caucuses. Their research may be some implications for the current debate over card check, although what those implications might be I leave to others, at least until SPSA.
