You might find something useful here: Is there a standard model for market impact? And Here's a decent paper about the cost impact on equities: http://www.cims.nyu.edu/~almgren/papers/costestim.pdf I would have added this as a comment but I don't have enough reputation
To start with the simplest model maybe you could start by googling "Kyle's Lambda" and proceed from there.
This is probably a nice paper you should refer to: Yogo, Koijen (2015) (link). They estimate an asset pricing model which endogenizes the price impact of large trades. It is a quite hard paper to grasp, so probably you do not want to start here, but is still one of the main references.
