応用一般均衡モデルにおける限定合理性を考慮した家庭の低炭素機器導入評価手法の提案

摘要

This paper suggests the new measure to calculate economic impact of deploying low carbon appliances at household sector. We point out that traaitional economic models, such as CGE models can only calculate economic impact of low carbon technologies negatively, because base year equilibrium is considered as the result of perfectly rational decision. We rather claim human behavior to be "bounded rational" as is pointed out by psychologists and behavioral economists. Once we consider human behavior to be under "bounded rationality", low carbon technologies can be evaluated as the ones to result in economic benefit. We suggest the way to deal bounded rationality in the traditional CGE model structure, even though new model can no more be called CGE model. This suggest i on is very important because it can change the result of econometric calculation of policies for low carbon future.%本発表では，通常の経済モデル，特に完全合理性を前提とする応用一般均衡モデルにおいて，低炭素機器の導入が必ずコスト増と計算されることについて問題提起を行い，別の分析方法を提案することを目的としている.
