I am curious if there is any sort of quantifiable difference between the prevalence of planned obsolescence of products in worker cooperatives versus capitalist businesses. It is clear that there is a difference at least between markets and planning if you look at products like long-lasting light bulbs and refrigerators in the centrally-planned economies of places like East Germany. Do you know if there is any literature or studies that have been performed on this topic? Perhaps there is an incentive in worker cooperatives to produce longer-lasting quality products or perhaps an incentive even to make MORE regularly-replaced disposable products? I would assume the answer is probably "no difference", but I would like to know if anyone has ever actually endeavored to investigate this topic.
