Obsolescence of durable goods and optimal purchase timing

Ennio Stacchetti, Dmitriy Stolyarov

    Research output: Contribution to journalArticlepeer-review


    We study a model with a durable good subject to periodic obsolescence and analytically characterize the optimal purchasing policy. The key result is that consumers optimally synchronize new purchases with the innovation cycle. The model simultaneously explains coordinated adoption without invoking network effects and provides a theoretical underpinning for a diffusion curve that features a temporary adoption slowdown.
