Riot assumes that when you duo with someone, your communication and teamwork are bound to be better than say, two random people thrown together by the gods, fates, and solo q. Therefore, there is an increase in your duo MMR to account for your increased communication, meaning you will be matched with people above your own personal MMR. I'm not entirely sure if duo q increases/decreases your LP gain, and someone else will have to confirm this, but I'm pretty sure that it doesn't affect your LP gain.
