IAM_COMPACT_Study_6_Interest_rates

This dataset contains the underling raw data of IAM COMPACT "Study 6 - Interest rates". Models used to assess decarbonisation pathways typically assume a uniform cost of capital; such assumption, however, does not do justice to real-world conditions and may therefore lead to inaccurate policy recommendations. The study aims to explore how non-uniform weighted average cost of capital (WACC), i.e., the discount rate a company uses to estimate its net present value, could influence global decarbonisation pathways. The study builds on empirically calibrated WACC values by region and technology in global IAMs and expands the modelling analysis by exploring stakeholder-driven pathways of de-risking clean energy technologies and risking fossil fuels. As one of the largest uncertainties lies in the way WACC values are expected to evolve over time, the empirical estimates of baseline WACC values are combined with an expert-based approach to produce forward-looking scenarios of evolving WACCs over time. The study also attempts to incorporate a corrective justice dimension in its narratives, by assessing the impacts of risk underwriting for low-carbon investments through taxing corporate windfall profits for 2022 and distributing the revenue as subsidies towards high-risk regions. Results of the study have been documented in D5.6 - Behaviour, social and disruptive innovation (DOI 10.5281/zenodo.12751959)本数据集涵盖IAM COMPACT“研究6——利率”的底层原始数据。 用于评估脱碳路径的模型通常假设统一的资本成本，但该假设并未贴合现实情境，或因此得出不准确的政策建议。本研究旨在探究非统一加权平均资本成本（Weighted Average Cost of Capital, WACC，即企业用于估算自身净现值的折现率）对全球脱碳路径的影响。 本研究以全球集成评估模型（Integrated Assessment Models, IAM）中分区域、分技术的经实证校准的WACC数值为基础，通过探究利益相关者主导的清洁能源技术降险、化石燃料增险路径，拓展了建模分析范畴。鉴于WACC数值随时间演进的路径是核心不确定性来源之一，本研究将基准WACC数值的实证估算结果与专家经验法相结合，生成了WACC随时间变化的前瞻性情景。本研究还尝试在分析框架中纳入矫正正义维度：通过对2022年企业超额利润征税，并将所得收入作为补贴发放至高风险区域，评估低碳投资风险承保所产生的影响。 本研究的相关成果已收录于D5.6——《行为、社会与颠覆性创新》（DOI：10.5281/zenodo.12751959）
