Optimal Environmental Taxation With Pre-Commitment And Green R&D, Stuart Mcdonald
Optimal Environmental Taxation With Pre-Commitment And Green R&D, Stuart Mcdonald
Stuart McDonald
Two approaches for modelling investment in R\&D have been developed by d'Aspremont and Jacquemin (AJ, 1988) and Kamien, Muller and Zang (KMZ, 1992), when there are spillovers associated with R\&D effort. This paper examines how these two approaches predict investment in green technology, when environmental policy takes the form of an optimal emission tax. The results show that the two models are equivalent when there are no R\&D spillovers; but when R\&D spillovers are present, significant differences in their predictions are observed. Specifically, the KMZ model predicts higher emission tax rates, higher level of R\&D expenditures and higher levels of …

Using a data set spanning the period 1899-2000, we construct a network of RJVs and track the pattern of growth of this network over time. The resulting R&D network is emergent in the sense that RJVs are contained within it, connected to other RJVs by the existence of firms sharing membership with multiple RJVs. This paper shows that the largest growth in the R&D networks occurred during the last three decades of the Twentieth Century. During this growth period, the R&D network has a pattern of collaboration that can be characterised as having the “small world” property. This has implications …
