Professor Lijphart's book was one of those that I learned about in graduate school, so it's certainly influential.
We haven't come to firm conclusions in our projects. Some of the most interesting work we've done has actually been in Ontario. We ran a very interesting experiment, in which we gave voters different ballots to see what would happen. We were able to hold constant preferences but change the way in which people would cast votes.
More recently, we ran a study around the European Parliament's elections, where we created fictional ballots made using real people—real European MPs—and we gave them different options. This is what I spoke of in my notes. It was about letting people vote in an open list system. This is where we found that everyone, females and males, voted for more female candidates as lists became more open, for women at a greater rate, so nonetheless, it was increasing.
