Ecological breakdown: What are externalities external to?

The 2018 Bank of Sweden Prize (falsely known as the Economics Nobel Prize) winner William Nordhaus opens the revised version of his Prize lecture as follows: “I begin with the fundamental problem posed by climate change – that is a public good or externality. Such activities are ones whose costs or benefits will spill outside the market and are not captured in market prices.”

The concept of externalities is a catch-all term, or, an empty box to capture the so-called spillover effects. Under the presumption that the market mechanism brings about the efficient allocation of resources, mainstream economic theory as well as many of its heterodox critiques argue for internalizing these spillovers by determining their costs (or benefits) and including it in the price of the commodity. In other words, the spillover effect itself must be turned into a commodity so that the market can efficiently handle it through the price mechanism.

Insofar as human-induced global warming has not been priced, so the story goes, it is an externality. In fact, it is today “the most significant of all environmental externalities” even in Nordhaus’ wisdom. Make no mistake – Nordhaus fiercely advocated inaction for over three decades, and portrayed projected levels of global warming, which are defined as devastating, or even catastrophic by scientists, as optimal.

Is Degrowth an Alternative to Capitalism?


The newest book by Giorgos Kallis, one of the most prolific degrowth advocates is entitled Limits: Why Malthus Was Wrong and Why Environmentalists Should Care. It is a short and accessible read which contains some important and unconventional arguments. In what follows, I will first briefly summarize the core arguments of the book, which promises to provoke important discussions on the matter of limits and subjects. Then I will reflect on the fuzziness of the primarily cultural conceptualization of capitalism, and argue that neither self-limitation nor degrowth qualifies as a mode of production, such that they could constitute an alternative to capitalism.Read More »

The Green New Deal: Whither Capitalism?


By Güney Işıkara and Ying Chen

The Green New Deal resolution by Alexandria Ocasio-Cortez and Ed Markey sparked an immense amount of discussion on all layers of political discourse, national and international. The way Ocasio-Cortez, Sanders and many others phrase the problem in the broader context of social, economic, and environmental grievances caused by capitalism is crucial for setting the terms of debate and struggle. This opens up space the left can use to address such issues in a systematic way rather than being content with symptomal healing. In fact, countless contributions have already been made on theoretical and tactical grounds. In this piece, we build on those contributions, and unpack the dynamics inherent to the capitalist system that would need to be addressed in the ongoing discussions. We also shed light on the limitations of a market-based and growth-centered approach to tackling climate destabilization, while offering other domains of political intervention such as property relations and demarketization of subsistence.Read More »
