The economic cost of a 130 kph speed limit in Germany: Comment
Gössling et al. (2023) claim to calculate the welfare effect of a 130 kph speed limit in Germany. By ignoring tax revenues from gasoline and diesel, they overestimate the welfare gain by about 378 million Euros. A speed limit raises travel times. Gössling et al. (2023) calculate travel time increases with a simplistic approach that underestimates the costs with a magnitude of their complete (tax adjusted) welfare effect. A speed limit induces some traffic to switch mode or not to travel at all. The reduced costs of less car travel are decisive for their calculation, but the losses of consumer rent associated with reduced travel are ignored. Gössling et al. (2023) do not calculate a value that is related to the welfare changes of a highway speed limit of 130 kph for Germany.
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.
