Get your phone out of the drawer: revealed and stated preferences

Blass, Vered; Tchetchik, Anat; Nichols, Austin

With short life cycles and fast changes in technology, more and more cellphones arrive at the end-of-use stage while retaining economic value, and many are suitable for reuse and recycling. But consumers make privately optimal decisions disregarding social externalities, and we study both the determinants of their choices via a discrete-choice experiment, and the effect of an experimentally assigned informational intervention on those choices. We present results from a comprehensive survey of 308 consumers conducted in Israel in 2014 using advanced discrete choice modeling with an efficient Bayesian design, and find that the informational intervention reduced decisional inertia for some consumers, lowered the propensity to trash an old phone, and decreased the intrinsic value of storing an obsolete phone.
