This Essay offers a framework to explain large-scale effective practices of sharing private, excludable goods. It starts with case studies of carpooling and distributed computing as motivating problems. It then suggests a definition for shareable goods as goods that are "lumpy" and "mid-grained" in size, and explains why goods with these characteristics will have systematic overcapacity relative to the requirements of their owners. The Essay next uses comparative transaction costs analysis, focused on information characteristics in particular, combined with an analysis of diversity of motivations, to suggest when social sharing will be better that secondary markets at reallocating this overcapacity to nonowners who require the functionality. The Essay concludes with broader observations about the attractiveness of sharing as a modality of economic production as compared to markets and to hierarchies such as firms and government. These observations include a particular emphasis on sharing practices among individuals who are strangers or weakly related; sharing's relationship to technological change; and some implications for contemporary policy choices regarding wireless regulation, intellectual property, and communications network design.
