Abstract

Recent analyses have highlighted the fact that the richest people contribute disproportionately to the increase in CO2 emissions, and thus to global warming. So far, the literature has mainly provided descriptive analyses linking wealth inequality to carbon inequality, raising concerns about the identification of the relationship between the two variables. Against this background, this paper advances the issue by examining the effect of wealth accumulation on carbon emissions, thus providing robust econometric validity. Based on a large sample of 200 countries from 1990–2020, our regression estimates support the hypothesis that wealth concentration significantly increases carbon inequality and accounts for nearly 20% of the CO2 emissions of the richest people. Our findings also highlight some heterogeneity, confirming the prominent role of industrialized and newly emerging countries such as China and India in global carbon emissions. Finally, transmission channel analysis suggests that the effect of wealth inequality on inequality in CO2 emissions is channeled through deterioration in institutional quality, captured by the level of democracy and environmental legislation introduction, and the marginal propensity to emit, captured by global emissions per capita.
财富不平等和碳不平等
最近的分析强调了这样一个事实,即最富有的人对二氧化碳排放量的增加,进而对全球变暖做出了不成比例的贡献。迄今为止,文献主要提供的是将财富不平等与碳不平等联系起来的描述性分析,引起了人们对这两个变量之间关系识别的担忧。在此背景下,本文通过研究财富积累对碳排放的影响来推进这一问题,从而提供可靠的计量经济学有效性。基于 1990-2020 年间 200 个国家的大量样本,我们的回归估计支持这样的假设,即财富集中会显著增加碳不平等,并占最富有人群二氧化碳排放量的近 20%。我们的研究结果还凸显了一些异质性,证实了中国和印度等工业化国家和新兴国家在全球碳排放中的突出作用。最后,传导渠道分析表明,财富不平等对二氧化碳排放不平等的影响是通过制度质量的恶化和边际排放倾向传导的,前者通过民主水平和环境立法的引入来体现,后者通过全球人均排放量来体现。

期刊介绍: Ecological Economics is concerned with extending and integrating the understanding of the interfaces and interplay between "nature''s household" (ecosystems) and "humanity''s household" (the economy). Ecological economics is an interdisciplinary field defined by a set of concrete problems or challenges related to governing economic activity in a way that promotes human well-being, sustainability, and justice. The journal thus emphasizes critical work that draws on and integrates elements of ecological science, economics, and the analysis of values, behaviors, cultural practices, institutional structures, and societal dynamics. The journal is transdisciplinary in spirit and methodologically open, drawing on the insights offered by a variety of intellectual traditions, and appealing to a diverse readership. Specific research areas covered include: valuation of natural resources, sustainable agriculture and development, ecologically integrated technology, integrated ecologic-economic modelling at scales from local to regional to global, implications of thermodynamics for economics and ecology, renewable resource management and conservation, critical assessments of the basic assumptions underlying current economic and ecological paradigms and the implications of alternative assumptions, economic and ecological consequences of genetically engineered organisms, and gene pool inventory and management, alternative principles for valuing natural wealth, integrating natural resources and environmental services into national income and wealth accounts, methods of implementing efficient environmental policies, case studies of economic-ecologic conflict or harmony, etc. New issues in this area are rapidly emerging and will find a ready forum in Ecological Economics.
