The willingness to sell personal data

Abstract

We elicit the willingness to sell personal data (contact information, Facebook details, preferences) in laboratory experiments, using a BDM and take-it-or-leave-it offers. Our experiments are novel in that (i) the experiments are incentivized, (ii) the focus on privacy issues is salient, and (iii) the use of the data - marketing purposes - is transparent and unambiguous. We find that only a minority of about 10% to 20% of the participants are unwilling to sell personal data, a share which is roughly constant across both the type of personal data and elicitation method. Subjects willing to sell request about € 15 for their contact details and € 19 for Facebook details.
