Well, as I indicated earlier, things like a chancellor's majority in Germany would clearly achieve greater stability or constructive...as opposed to no confidence.
First of all, coalitions themselves are a key part of providing stability, and we don't have that right now. I think it's one of the misconceptions that if you adopt PR you're going to end up with coalitions. I suggest that coalitions arise when parties have to obtain the confidence of the House before they're sworn into government. We have the opposite here. In Canada, we choose either that the prime minister continues on as the government and swears in his new cabinet, or he resigns following the election and the second-most popular party takes power and is sworn in. It's only after that that we have a Speech from the Throne and the prime minister is in power for a period of time. Then finally, several months later, we test the confidence of the House.
By doing it in that fashion, you don't get coalition governments, and that's why we haven't had any. We're not going to naturally evolve into having coalition governments just because we adopt a system that creates more minority parliaments.
