Exploration of these production communities reveals the deeply contingent processes of collective action that sustain them---processes that are innovative and powerful but sometimes fragile. As this shared body of digital infrastructure has grown, some crucial pieces have become neglected, leading to <i>underproduction</i>: the phenomenon of highly important, low-quality software packages. Underproduction is a form of what I will call a <i>social production failure</i>, and a substantial source of risk to digital infrastructure that today is used by billions of people. This dissertation is framed around a series of methodological and empirical projects. The first proposes a method for measuring underproduction risk in cross-section and demonstrates the application of that method to the Debian GNU/Linux community. Next, I examine the social and technical conditions of the Debian community and test hypotheses about how these conditions are associated with underproduction. I then develop a method to measure underproduction longitudinally, and apply this method to projects in Debian written using the Python programming language. I close by synthesizing these results with respect to my proposed theory of social production failures, and offer propositions and proposals for future work.application/pdfen-USCC BY-SAcollective actiondigital infrastructureopen source softwareorganizingpeer productionCommunicationInformation scienceComputer scienceCommunicationsThesis
