AbstractTechnology-rich Integrated assessment models (IAMs) and Environmentally-Extended Input–Output Analysis (EEIOA) are widely employed for sustainability analysis, each offering unique strengths. IAMs focus on forward-looking scenarios, exploring technological shifts and climate change mitigation costs. EEIOA provides more comprehensive but static assessments of environmental and socio-economic impacts throughout supply chains, adopting a lifecycle perspective. I conduct a literature review to assess the current state of IAM-IO integration, paving the way for future research opportunities with advanced models. Existing studies have loosely linked IAM and IO models to improve one field or the other. This perspective highlights the potential for more advanced IAM-IO model linking and identifies three domains within sustainability scenarios research where IAM-IO integration could play a crucial role: the energy-industry nexus in decarbonization pathways, multi-dimensional sustainability impact assessment and demand-side solutions and post-growth climate mitigation scenarios. The expected research insights may be pivotal to design effective sustainable policies.KEYWORDS: Integrated Assessment ModelsInput–output analysismodel linkingsustainabilityclimate mitigation scenarios Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1 Including integrated assessment model, energy model, scenarios, input–output, lifecycle assessment.2 For constructing the core literature review which is focused on IO, I have only retained hybrid LCA-IO studies that include an explicit IO component.

摘要技术含量高的综合评价模型(IAMs)和环境扩展投入产出分析(EEIOA)在可持续发展分析中应用广泛,各有其独特的优势。iam侧重于前瞻性情景,探索技术转变和减缓气候变化的成本。EEIOA采用生命周期的观点,对整个供应链的环境和社会经济影响提供了更全面但静态的评估。我进行了文献综述,以评估IAM-IO集成的现状,为未来使用先进模型的研究机会铺平道路。现有的研究将IAM和IO模型松散地联系起来,以改进一个领域或另一个领域。这一观点强调了更先进的IAM-IO模型联系的潜力,并确定了可持续性情景研究中IAM-IO一体化可发挥关键作用的三个领域:脱碳途径中的能源-工业联系、多维可持续性影响评估和需求侧解决方案以及增长后气候缓解情景。预期的研究见解可能对设计有效的可持续政策至关重要。关键词:综合评估模型投入产出分析模型链接可持续性气候减缓情景披露声明作者未报告潜在的利益冲突。注1包括综合评价模型、能量模型、情景、投入产出、生命周期评价为了构建专注于IO的核心文献综述,我只保留了包含显式IO组件的混合LCA-IO研究。然而,我也考虑了其他一些更专注于LCA方法的论文,以正确看待IO方法,并强调LCA方法与IO相比的特定优势。

Anticipated increase in future river flood risk highlights the need for effective flood insurance, as it enables hedging against this risk. However, its design varies significantly across countries. This study contributes to the debate on designing flood insurance mechanisms from an economy-wide perspective, considering both socioeconomic and climate changes. We apply a multi-regional computable general equilibrium (CGE) model for 2050 and find that, under current insurance market systems, flood risk causes regional GDP losses of up to −0.5%, societal welfare losses of up to −1%, and private and public consumption losses of up to −0.5% and −2.4%, respectively. These estimates are all relative to a scenario without flood risk. Our results indicate that flood risk intensifies pressure on public budgets. We find that insurance market reforms, including a higher degree of risk-sharing, mandatory purchase requirements, and public reinsurance, can alleviate adverse welfare effects and the burden on public budgets.
预计未来河流洪水风险的增加凸显了有效的洪水保险的必要性,因为它可以对冲这种风险。然而,不同国家的设计差异很大。本研究有助于从经济角度设计洪水保险机制的讨论,同时考虑社会经济和气候变化。我们应用2050年的多区域可计算一般均衡(CGE)模型发现,在当前的保险市场体系下,洪水风险导致地区GDP损失高达- 0.5%,社会福利损失高达- 1%,私人和公共消费损失分别高达- 0.5%和- 2.4%。这些估计都是相对于没有洪水风险的情况。我们的研究结果表明,洪水风险加剧了公共预算的压力。我们发现,保险市场改革,包括更高程度的风险分担、强制性购买要求和公共再保险,可以减轻不利的福利影响和公共预算负担。

Empirical evidence increasingly indicates that to achieve sufficiently rapid decarbonisation, high-income economies may need to adopt degrowth policies, scaling down less-necessary forms of production and demand, in addition to rapid deployment of renewables. Calls have been made for degrowth climate mitigation scenarios. However, so far these have not been modelled within the established Integrated Assessment Models (IAMs) for future scenario analysis of the energy-economy-emission nexus, partly because the architecture of these IAMs has growth ‘baked in’. In this work, we modify one of the common IAMs – MESSAGEix – to make it compatible with degrowth scenarios. We simulate scenarios featuring low and negative growth in a high-income economy (Australia). We achieve this by detaching MESSAGEix from its monotonically growing utility function, and by formulating an alternative utility function based on non-monotonic preferences. The outcomes from such modified scenarios reflect some characteristics of degrowth futures, including reduced aggregate production and declining energy and emissions. However, further work is needed to explore other key degrowth fea-turessuchassectoraldifferentiation,redistribution,andprovisioningsystemtransformation.
越来越多的经验证据表明,要实现足够快的脱碳,除了快速部署可再生能源外,高收入经济体可能需要采取去增长政策,缩减不太必要的生产和需求形式。已经有人呼吁制定减少生长的气候减缓情景。然而,到目前为止,这些还没有在已建立的综合评估模型(iam)中建模,用于能源-经济-排放关系的未来情景分析,部分原因是这些iam的架构已经“烘烤”了增长。在这项工作中,我们修改了一个常见的iam—MESSAGEix—使其与去生长场景兼容。我们模拟了高收入经济体(澳大利亚)的低增长和负增长情景。我们通过将MESSAGEix与其单调增长的效用函数分离,并根据非单调偏好制定替代效用函数来实现这一点。这种修正情景的结果反映了去增长未来的一些特征,包括总产量减少、能源和排放下降。然而,需要进一步的工作来探索其他关键的去增长特征,如部门分化、再分配和供应系统转型。

We extend the regional input-output model for the economic impact assessment of Covid-19 lockdowns in Italy proposed in Reissl et al. (2021) by incorporating the effects of changes in mobility on the level and composition of consumption demand. We estimate the model on sectoral data for 2020 and perform an out-of-sample validation exercise for the first half of 2021, finding that the model performs well. We then evaluate the relative importance of demandand supply-side factors in determining our simulation results. During the national lockdown of spring 2020 the impacts of supply-side (labor) shocks can account for the vast majority of output losses. In the following stages of the epidemic income and mobility-related effects on final demand play pivotal roles at the aggregate and regional levels, as well as for most sectors. While policies supporting demand may hence be appropriate, their effectiveness may be hampered when demand is chiefly restrained by the mobilityrelated effect, and not by income.
我们扩展了Reissl等人(2021)提出的意大利新冠肺炎封锁经济影响评估的区域投入产出模型,纳入了流动性变化对消费需求水平和构成的影响。我们根据2020年的部门数据估计了该模型,并在2021年上半年进行了样本外验证,发现该模型表现良好。然后,我们评估了需求和供应方因素在确定模拟结果中的相对重要性。在2020年春季的全国封锁期间,供应侧(劳动力)冲击的影响可以解释绝大多数产出损失。在疫情的以下阶段,收入和流动性对最终需求的影响在总体和区域层面以及大多数部门发挥着关键作用。因此,虽然支持需求的政策可能是适当的,但当需求主要受到流动性相关效应而非收入的限制时,其有效性可能会受到阻碍。

AbstractThe input-output network of an industrial chain provides a channel for risk transmission. Using Smooth-Transition Vector Autoregression model (STVAR) and Diebold-Yilmaz directional connectedness measures, we explore tail risk (extreme risk) contagion across China’s automotive industrial chain. We find significant spillover effects that are asymmetric in different phases of China’s business cycle, monetary cycle, and policy uncertainty. When China’s economy is in a recession, under a monetary expansion, or at a high level of policy uncertainty, the total risk spillover across the chain is higher. We also find apparent risk spillover from the financial services industries to the automotive industrial chain as China’s economy is in a recession or a monetary expansion period. Still, a reverse spillover is found as policy uncertainty is at a high level. Meanwhile, the direction of risk propagation across the automotive industrial chain may change with the transition in the economic state or policy uncertainty state.KEYWORDS: Tail riskinput–output linkageasymmetric contagionChina’s automotive industrial chainJEL Classifications: C34E32E42F13L62 Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1 The data for some variables in our research, such as the manufacturing PMI index, is only available from January 2005.2 The stock index of China’s insurance industry starts from January 2007, so we set its CoVaRs between January 2005 and November 2006 constant, equaling the CoVaR of January 2007.3 We collect data on China’s manufacturing PMI, CCI, MSR, and IOR from the WIND database of China.4 The Trade Policy Uncertainty Index (based on mainland newspapers) was made by Davis et al.

【摘要】产业链的投入产出网络为风险传递提供了渠道。本文采用平滑过渡向量自回归模型(STVAR)和Diebold-Yilmaz定向连通性测度,探讨了尾部风险(极端风险)在中国汽车产业链上的传染。我们发现,在中国经济周期、货币周期和政策不确定性的不同阶段,溢出效应是不对称的。当中国经济处于衰退、货币扩张或政策高度不确定性时,整个链条的总风险溢出更高。我们还发现,当中国经济处于衰退或货币扩张时期时,金融服务业的风险会明显溢出到汽车产业链。然而,由于政策不确定性较高,出现了反向溢出效应。同时,在经济状态或政策不确定状态下,汽车产业链的风险传播方向可能会随着转型而发生变化。关键词:尾部风险投入产出关联不对称传染中国汽车产业链分类:C34E32E42F13L62披露声明作者未报告潜在利益冲突。注1在我们的研究中,一些变量的数据,如制造业PMI指数,只有2005年1月的数据。5.2中国保险业股票指数从2007年1月开始,因此我们将其2005年1月至2006年11月的CoVaR设为常数,等于2007年1月的CoVaR。4贸易政策不确定性指数(基于大陆报纸)由Davis等人(Citation2019)编制。可以在www.policyuncertainty.com上找到。Huang和Luk (Citation2019)构建的汇率和资本项目政策不确定性指数(基于114家大陆报纸的完整样本)可在http://economicpolicyuncertaintyinchina.weebly.com.9上获得。我们使用两个复合指标来检验经济陷入衰退的概率是否与中国经济的衰退日期相匹配。一种是中国国家统计局发布的宏观经济景气指数(MCI)。另一个指标是由经合组织设计的综合领先指标(CLI)。基于MCI,我们发现有77个月处于衰退状态,占样本周期的38.9%。基于CLI,我们发现样本周期中的76个月被确定为衰退日期,占198个样本月总数的38.4%。在我们的研究结果中,PMI或CCI的过渡函数F(zt)小于0.5的月数为74个,约占总数的37.4%。根据MCI和CLI,经济陷入衰退的可能性大致与中国经济的衰退日期相对应在国家经济研究局衡量衰退持续时间的惯例中,衰退的第一个月是高峰之后的一个月,最后一个月是低谷的一个月基于Schwarz信息准则,我们选择了两个滞后点。估计的平滑参数γ和阈值参数c,定义在公式8中,PMI分别为7.7和- 0.4,CCI分别为6.3和-0.6我们检查关于不同顺序的内生变量的结果的稳健性。在我们的STVAR模型中,有9个内生变量,所以有9!= 362880种可能的顺序。出于计算上的考虑,我们根据状态变量的位置将所有排序分为三个子组,即状态变量分别放在第一、中间和最后。然后,从每个子组中随机选择10个不同的排序。在整个过程中,我们发现“从一个行业到另一个行业的风险溢出”、“总风险溢出”和“净风险溢出”完全没有变化基于Schwarz信息准则,我们选择了两个滞后点。公式8中定义的估计平滑参数γ和阈值参数c的MSR分别为5.4和0.7,IOR分别为6.6和-0.4基于Schwarz信息准则,我们选择了两个滞后点。估计的平滑参数γ和阈值参数c,定义在式8中,TPU分别为3.7和0.2,ECPU为5.2和0.9。本研究由国家自然科学基金资助:[批准号:72171100];教育部人文社科基金项目:[批准号:18YJA790037]。
