この論文は、統合評価モデルDICEにケインズ型の投資乗数を導入し、脱炭素化投資が雇用と生産を促進する可能性を示す。標準的なDICEよりも迅速な脱炭素化が必要であり、乗数が0.75以上で1.5°C～2°Cの経路が支持される。また、迅速な脱炭素化が経済成長を加速する可能性を示唆している。
English
This paper incorporates Keynesian investment multipliers into the DICE model, showing that climate investments can increase employment and output. Results support faster decarbonization than standard DICE recommends, with pathways consistent with 1.5°C–2°C for multipliers of 0.75 or greater, and suggest rapid decarbonization can lead to faster economic growth.

📄 Abstract（原文）
Abstract Integrated assessment models (IAMs) assume that economies operate on the efficiency frontier, resulting in hard tradeoffs between decarbonization, consumption, and investment. Meanwhile, Keynesian models recognize that climate investments can increase employment and output today. This paper attempts to bridge these literatures through a simple modification of the most well-known IAM. We review the neoclassical economic assumptions underpinning dynamic integrated climate-economy model (DICE) and incorporate a range of investment multipliers into DICE that reflect economists’ uncertainty about how climate investments affect output. Our results suggest that decarbonization should be undertaken more rapidly than standard DICE recommends and provides support for pathways within the range of 1.5 °C–2 °C for investment multipliers of 0.75 or greater. The addition of an investment multiplier also suggests that rapid decarbonization can lead to faster economic growth.
