Shared Information Goods

open access: yesSSRN Electronic Journal, 1998
Once purchased, information goods are often shared among groups of consumers. Computer software, for example, can be duplicated and passed from one user to the next. Journal articles can be copied. Music can be dubbed. In this paper, we ask whether these various forms of sharing undermine seller profit.
