digital downloads have the secondary effect of entirely cutting out the popular market for second-hand films and games — a plus for publishers, but a big negative for the consumer
It's a negative for publishers, too. Just as with cars and many other products, a healthy used market supports high prices for new products. Buyers are more willing to pay full price for new when they know they can trade it in or resell it for a substantial portion of the purchase price. Eliminating the secondary market reduces the overall demand for new products, reducing prices, unit sales, or both.
