The Economics of Privacy at a Crossroads

Abstract

By several accounts, the economics of privacy has grown into a remarkably successful field of research. As the means of collecting and using individuals’ data have expanded, so has the body of work investigating trade-offs associated with those data flows. The number of scholars working in the area has grown, much like the breadth of topics investigated. References to the economic value of personal data have become common in policy and regulation, and so have mentions of economic dimensions of privacy problems. Thinly veiled underneath those successes, however, lies a less encouraging trend. In this manuscript, I argue that the very success of the economics of privacy has laid the foundation for a potentially adverse effect on the public debate around privacy. Economic arguments have become central to the debate around privacy. When used as complements to considerations less amenable to economic quantification, those arguments are valuable tools: they capture a portion of the multiform implications of evolving privacy boundaries. When, instead, economic arguments crowd out those other noneconomic considerations from the public discourse around privacy, problematic scenarios arise. In one scenario, the economic analysis of privacy will keep growing in influence, but its overly narrow conception of privacy will impoverish rather than augment the depth of the debate around privacy. In a second scenario, less likely but equally problematic, the economics of privacy will progressively undermine its own relevance by failing to account for the complexity and nuance of modern privacy problems. There is a third scenario—one this manuscript explores. The economics of privacy may expand its horizons and relevance both by considering economic dimensions and research questions that have so far received limited attention, and by accounting for the broader scholarship on privacy coming from other disciplines. As a complement to the contributions of other fields, rather than a substitute for them, the economics of privacy may keep thriving and remain a useful tool for debate and policymaking.
