Abstract:
This paper presents a model-based analysis of the development and diffusion of so-called ‘green’ products, i.e. those which are easily recyclable and which have a long lifetime. We address this problem by developing an evolutionary simulation model to identify the impact of the environmental R&D strategies of business firms on the economy and the environment. The simulation results show that R&D investment both in product recyclability and in product lifetime extension can be positive for the firm. Adopting such a strategy means that the firm can then market green products, which provides it with a competitive advantage on firms investing mainly in product recyclability whatever consumers' preferences. From an environmental point of view, the diffusion of green products will reduce both waste flows in the economy and pressure on virgin resources. However, diversifying R&D investment to develop both product recyclability and lifetime can mean slowing down the flow of recycled materials and may lead to even greater quantities of unrecycled waste. Our results suggest introducing regulation policies aiming at encouraging firms to invest both in product recyclability and lifetime in order to benefit from their complementarities. Furthermore, simulations show that it should be better to direct environmental policies on firms' environmental innovation strategies than on demand attributes because significant changes in these strategies would provide much more radical environmental changes.
