演講摘要 : Limiting global warming requires immediate and substantial collective action to reduce carbon emissions, but concerns about economic impacts deter some countries from committing to such efforts. This paper examines how decarbonization policies generate unemployment along the transition path, using a dynamic quantitative general equilibrium model of international trade and environment that incorporates downward nominal wage rigidities as a source of unemployment. Our quantitative results, consistent with a simple theoretical model, show that uniform carbon reduction rates across countries lead to heterogeneous unemployment effects. Countries with more emission-intensive technologies or sectoral compositions experience deeper and more persistent transitional short-run unemployment. We also show that the Paris Agreement's proposed reductions are relatively fair in terms of unemployment; however, achieving meaningful climate goals requires active participation from more emission-intensive countries, emphasizing the need for stronger global cooperation to transition to a greener global economy.
