Carbon Taxes, Path Dependency and Directed Technical Change: Evidence from the Auto Industry

Aghion, Philippe; Dechezleprêtre, Antoine; Hemous, David; … - C.E.P.R. Discussion Papers - 2012

innovation distinguishing between "dirty" (internal combustion engine) and "clean" (e.g. electric and hybrid) patents across 80 … tax-inclusive fuel prices. Furthermore, there is path dependence in the type of innovation both from aggregate spillovers … and from the firm's own innovation history. Using our model we simulate the increases in carbon taxes needed to allow …
