Using a stylized model of endogenous product quality improvement and remanufacturing we find that the main driver of the contradicting results is the change in manufacturing costs caused by improving product quality. A strong increase in manufacturing costs due to product quality improvement may induce the firm to take up remanufacturing when introducing the new product. Conversely, a small impact of product quality improvement on manufacturing costs reverses this effect and may indeed lead the firm to cease remanufacturing when introducing the new product. We find that the latter outcome is never beneficial from an environmental point of view, while the former always is. With endogeneous product quality improvement we then characterize conditions where a remanufacturing manufacturer would take a different product quality improvement decision than a non-remanufacturing manufacturer. We observe that remanufacturing stifles (stimulates) product quality improvement when manufacturing cost of quality improved product are low (high). Neither of the two results are exclusively beneficial or detrimental from an environmental perspective and we characterize the conditions under which product quality improvement is preferable.
