Effects of Remanufacturable Product Design on Market Segmentation and the Environmen

Despite documented benefits of remanufacturing, many manufacturers have yet to embrace the idea of tapping into remanufactured-goods markets. In this article, we explore this dichotomy and analyze the effect of remanufacturable product design on market segmentation and product and trade-in prices by studying a two-stage profit-maximization problem in which a price-setting manufacturer can choose whether or not to open a remanufactured-goods market for its product. Our results suggest that it is optimal for a manufacturer to design a remanufacturable product when the value-added from remanufacturing is relatively high but product durability is relatively low and innovation is nominal. In addition, we find that entering a remanufactured-goods market in and of itself does not necessarily translate into environmental friendliness. On the one hand, the optimal trade-in program could result in low return and/or remanufacturing rates. On the other hand, a low price for remanufactured products could attract higher demand and thereby potentially result in more damage to the environment. Meanwhile, external restrictions imposed on total greenhouse gas emissions draw criticism in their own right because they risk stifling growth or reducing overall consumer welfare. Given these trade-offs, we therefore develop and compare several measures of environmental efficiency and conclude that emissions per revenue can serve as the best proxy for emissions as a metric for measuring overall environmental stewardship.

Quality design and environmental implications of green consumerism in remanufacturing

We study quality design and the environmental consequences of green consumerism in a remanufacturing context. Specifically, a firm has the option to design a non-remanufacturable or a remanufacturable product and to specify a corresponding quality, and the design choices affect both the production costs and consumer valuations associated with the product. On the cost side, remanufacturable products cost more to produce originally, but less to remanufacture, than non-remanufacturable products cost to produce. Analogously, on the consumer side, remanufacturable products are valued more, but remanufactured products are valued less, than non-remanufacturable products are valued. Given this, we investigate the environmental consequences of designing for remanufacturability by first defining a measure of environmental impact that ultimately is a function of what is produced and how much is produced, and then applying that measure to assess the environmental impact associated with the firm׳s optimal strategy relative to the environmental impact associated with the firm׳s otherwise optimal strategy if a non-remanufacturable product were designed and produced.
