There's also the anchoring theory, where the discussion centres around the first number that any party says out loud. So in the case where the company goes first they might offer a low number (for them) which may be reasonable for you but not what you want.

So the way to use that to your advantage is to say a number first, but make sure it is far more than what you think you can get, but not absurdly high. That way if they accept you'll be pleasantly surprised, but if they negotiate down it will be around that figure.

Of course if you're not confident in that, just let them put out the first number and go from there. But NEVER tell them what you are currently getting, that will anchor your salary to what it is now plus a small increase.
