OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
We study the quantitative effects of a carbon tax in a dynamic, general equilibrium model with production heterogeneity and technology adoption. The vintage technology available to a firm determines its emission rate. Adopting newer technology is
subject to a non-convex adjustment cost that leads firms to have (S,s) policy functions for technology and capital adjustment. We show that firm heterogeneity in emission rates determines the aggregate effects of a carbon tax in the short- and long- run. GDP losses from a representative firm model are more than double those with heterogeneous emission rates. Short-run effects depend on the policy implementation.
