Climate change - environmental and technology policies in a strategic context
Environmental and Resource Economics, 37, 159-180, 2007
There are a number of features of climate change which make it one of the most challenging problems confronting policy makers and policy analysts. In this paper we consider three such features: (i) climate change is a global pollutant so there are strategic interactions between governments over climate policy; (ii) cutting greenhouse gas emissions can have significant cost effects across a number of sectors of the economy, raising concerns about the implications of climate change policy on competitive advantage; (iii) the long-time scales on which climate change operates means that an important dimension of climate change policy is policy towards R&D to cut the costs of dealing with climate change. In Ulph and Ulph (1996) [Ulph A, Ulph D (1996) In: Carraro C, Katsoulacos Y, Xepapadeas A (eds) Environmental policy and market structure. Kluwer, Dordrecht, pp 181–208] we presented a model to analyse these issues, but considered only environmental policies. In this paper we extend that analysis to allow for both a richer set of policy instruments (environmental and technology policies) and a richer strategic context.
