摘要：The paper analytically explores the optimal policy mix between mitigation and environmental
adaptation against climate change at a macroeconomic level. The constructed economicenvironmental
model is formulated as a social planner problem with the adaptation and abatement
investments as separate decision variables. The authors prove the existence of a unique steady state
and provide a comparative static analysis of the optimal investment. It leads to essential implications
for associated long-term environmental policies. In particular, the dependence of the optimal ratio
between abatement and adaptation investments on economic efficiency appears to have an inverted
U-shape. Data calibration and numerical simulation are provided to illustrate theoretical outcomes.
