Thank you. It's a very good question.
I think the committee shouldn't be too hopeful that changing an electoral system is going to have a large number of effects, either positive or negative, on things like macroeconomic outcomes or budget management. It seems to me that these things are largely baked in, depending on a country's place in the global economy, on the nature of its resources, and on the democratic dynamics of its population. When we look at studies that extract cross-national differences and then attribute causality to the electoral system, I think we should view them with a fair amount of skepticism.
By the way, I could probably, with some ease, point you to some studies that would show that majoritarian countries have some better outcomes as well on some of these measures. For the most part, I think those things are pretty far down the chain, and they're probably not affected by electoral systems too much.
The things that will be affected in a beneficial way by changing the electoral system are probably a bit more with regard to voter turnout, and, as you say, a better sense of fairness with the election outcome. Those are good, right? We'll likely have more women in Parliament, which is good, but they trade off against other things.
