Yes. On financial incentives, I suppose that if parties don't select a certain per cent of women candidates or candidates from other politically marginalized groups as well, you could have a threshold of 10%, or some wiggle room, so that if they don't select a certain per cent, then they don't receive a subsidy. That could be in safe seats or, if you wanted, all seats. That's up to you.
That would be a financial incentive. It's a way of framing it that makes it sound more positive than “quota”.
