Climate Policy and Trade: Dynamics and the Steady-State Assumption in a multi-regional Framework
Katrin Springer
Abstract: Most dynamic trade models assume steady state or balanced
growth. This paper argues while this can be done in a single region model
or a model without trade, the steady state assumption is problematic in a
multi-regional setting with trade interactions. This paper shows the
consequences of assuming a balanced growth path and discusses several
problems which are connected to the calibration of recursive dynamic
multi-regional trade models. Furthermore, it is demonstrated how different
dynamic specifications of the base run path affect the results of a policy
scenario by imposing the Kyoto Protocol. The simulations illustrate that a
balanced growth path can not be maintained in a multi-regional trade model
due to international trade spill-overs. It is shown that the model results
and thus the assessment of climate policy options depend substantially on
the dynamic specification.
