“Despite the many advantages conferred by digital goods, comparable versions of physical goods are valued more. When a physical good such as a paper book, a printed photograph, or a DVD is digitized, it loses some of its value to buyers. Our experiments suggest that the key driver of this value loss is not the resale value of the good, or how much it costs to make, or how long it can be used, or whether it’s unique or popular. We find that the key difference is that digital goods do not facilitate the same feeling of ownership that physical goods do.”
