Abstract
Focusing on biodiversity risks, we perform an empirical asset pricing analysis and document three main results. First, the factor going long on low biodiversity intensity assets and short on high biodiversity intensity ones as well as the factors based on the biodiversity intensity subcomponents (land use, greenhouse gases—GHG, air pollution, and water pollution) have heterogeneous dynamics but are not spanned by the Fama and French (2015) and carbon factors. Second, the biodiversity factor excluding the GHG subcomponent (ex-GHG) commands a positive risk premium on realized returns and a negative one on expected returns in the sector highly exposed to the double materiality of biodiversity risks (i.e., physical and transition risks). Third, we show that the negative premium of both the biodiversity and the ex-GHG biodiversity factors on expected returns has materialized strongly from 2021 onward and that it amplifies with attention to biodiversity issues and risk aversion.
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.
