I've had negative reputation in my village for a while and finally unlocked the last trades for a villager. Completing trades in the Master category is supposed to give you +1 reputation. My reputation couldn't have been lower than -14, because at -15, iron golems will target the player, and the ones that have spawned in my village are not. I did over 15 trades, 18 specifically, and the prices for all the villagers are still raised as if I had negative reputation. I don't know what else I'm supposed to do. Additionally, when I was killing iron golems and villagers (which caused my reputation to drop), the golems did not attempt to attack me, both when hitting villagers and the golems themselves.
