Abstract: The European Union has implemented demand push and technology pull policies to foster innovation on the energy and resource efficiency of capital goods. The state of the art of general equilibrium modelling applied to environmental policy rarely treats product and process innovation separately and product quality is, in the best case, exogenous. We develop a dynamic multi-sector CGE model that distinguishes between R&D-based process innovation for all firms, endogenous product innovation in the capital goods sector and adoption decisions with respect to the installation of new capital vintages in the rest of the economy. Our results support the previous literature in finding that aggregate innovation declines following an energy tax but whereas process innovation is reduced, product innovation actually rises. We find that demand pull policies are less effective than product-related R&D subsidies to reduce aggregate energy intensity.
