متن کاملEnergy Efficiency and Directed Technical Change
I construct a putty-clay model of directed technical change and use it to analyze the effect of environmental policy on energy use in the United States. The model matches key data patterns that cannot be explained by the standard Cobb-Douglas approach used in climate change economics. In particular, the model captures both the shortand long-run elasticity of substitution between energy and non-...
متن کاملNatural Resource Wealth and Directed Technical Change
This paper analyses the e¤ect of endogenous directed technical change in a resource-rich economy, embedding a version of Acemoglus model of directed technical change in a three-by-three trade theory model. Technical progress depends on entrepreneurs who either produce or adopt technology, and who endogenously choose which sector to operate in. The static e¤ect of a resource discovery is de-ind...
متن کاملThe Environment and Directed Technical Change.
This paper introduces endogenous and directed technical change in a growth model with environmental constraints. The final good is produced from "dirty" and "clean" inputs. We show that: (i) when inputs are sufficiently substitutable, sustainable growth can be achieved with temporary taxes/subsidies that redirect innovation toward clean inputs; (ii) optimal policy involves both "carbon taxes" a...
متن کاملDirected Technical Change, Unilateral Actions, and Climate Change
In this paper, I investigate the implications of policy-induced technological change based on a multi-region variant of the directed technical change model developed by Acemoglu et al. (2012). On top of the pollution externality accompanied by carbon dioxide emission, different regions are connected through a global market where energy-related machine producing firms monopolistically compete wi...
