Security, At What Cost? Quantifying People’s Trade-offs Across Liberty, Privacyand Security

This paper discusses a study that uses the stated preference method to measure and quantify trade-offs in the United Kingdom between security, on the one hand, and liberty and privacy, on the other. It also translates the results into economic units, by asking the survey respondents how much they would be willing to pay to satisfy their concerns. Three case studies are presented: applying for a passport, riding on the national rail network, and attending a public event. Survey respondents are asked questions that would shed light on the trade-offs in privacy and liberty they are willing to make, to increase security in these settings.
