Well, one way is to look at shocks to reselling or buying used (new regulation, DRM, etc.) and see how much demand for new products decreases because of the de facto price increase.
Another way might be to think of reselling as a subsidy to buying new—a rebate, if you will. If you can estimate how much a discount would increase sales and the producers’ profits, then you can take the average resell price times probability someone will resell and treat that as a discount and figure out from there.
I know I’ve read economics research on this topic in the past, so you can probably google up some good papers.
