Economist Steve Keen explores the origins of energy blindness in modern economic theory, discussing how the massive carbon surplus has been overlooked in describing wealth and productivity. The podcast also delves into the history of economics and the role of physiocrats, the flaws in neoclassical economics, and the neglect of energy in production. The speakers analyze the relationship between energy, technology, and human creativity, and criticize economists' approach to energy and climate change.
Mainstream economic theories have neglected the role of energy in production, hindering accurate analysis of real-world situations.
Energy plays a crucial role in driving economic productivity and human welfare.
A more comprehensive approach that incorporates energy into economic theories is necessary to address current challenges and shape a sustainable future.
Deep dives
The Evolution of Economic Theories
The podcast episode explores the evolution of economic theories and their treatment of energy in production. It starts with the physiocrats, who recognized the importance of energy, particularly from land, in generating wealth. However, Adam Smith's work shifted the focus to labor as the source of value. Neoclassical economists continued this understanding, assuming labor and capital as the drivers of production and largely ignoring the role of energy. The Cobb-Douglas production function solidified this perspective, creating a false sense of the contributions of labor, capital, and technology while entirely neglecting energy. Neoclassical economists still adhere to this outdated view, despite its flaws and contradictions with empirical evidence.
The Role of Energy in Production
Energy plays a crucial role in production, necessary for both labor and capital to function. While laborers require energy for physical work, capital relies on energy to power machinery and perform tasks more efficiently. The amount of work that can be done by humans has remained relatively constant over time, while machines have significantly increased their energy consumption and output capacity. This growth in energy consumption has been instrumental in driving economic productivity and human welfare.
The Failure to Incorporate Energy into Economic Theories
Mainstream economic theories, such as the Cobb-Douglas production function, have failed to properly account for the role of energy in production. By excluding energy as an independent factor and treating it as an additional input alongside labor and capital, these theories overlook its critical significance. Neoclassical economists have not recognized that energy is a fundamental input, and instead have relied on outdated assumptions about the contributions of labor and capital to output. This oversight undermines their understanding of economic dynamics and hinders accurate analysis of real-world situations.
The Need for a New Approach
A more comprehensive approach is necessary to incorporate energy into economic theories. This requires recognizing that labor and capital critically depend on energy for their functioning and productivity. By embracing an energy-centric perspective, economists can gain a deeper understanding of the complex interactions between energy, labor, capital, and output. This new approach would not only provide more accurate economic analysis, but also enable informed decision-making to address current challenges and shape a sustainable future.
The Role of Energy in the Production Function
The podcast episode discusses the importance of energy in the production function. It challenges the traditional neoclassical economic view that labor and capital are the main drivers of wealth, arguing that energy is the fundamental input that transforms into useful work. The speaker emphasizes that humans have significantly advanced due to their ability to exploit energy, particularly from fossil fuels. The episode highlights the blindspot of economists who neglect the role of energy and its direct correlation to GDP growth. Additionally, it explores the implications of this oversight on climate change and the urgent need to shift towards alternative energy sources.
The Blindness of Neoclassical Economists and the Implications for Society
The podcast challenges the credibility of neoclassical economists and their failure to acknowledge the significance of energy in the production function. It criticizes their belief that economic growth is driven primarily by labor and capital, disregarding the vital role of energy. The episode argues that economists' negligence of energy has led to distortions in economic models and inadequate understanding of climate change. It highlights the importance of engineers in addressing the energy crisis and developing alternative technologies. The speaker concludes by urging young people to challenge the current economic paradigm and focus on the role of energy in shaping our civilization's future.
On this episode, economist Steve Keen offers a deep forensic history of why modern economic theory has neglected the role of energy in productivity - and why this “Energy Blindness” is now a major blindspot in how our culture views the present - and the future. The massive, temporary carbon surplus we’ve extracted over the last few centuries has resulted in an exponential increase in the standard of living for many. This explosion of global economic growth also happened to coincide with the development of all modern economic theories and formulas, leading to a core misunderstanding in the way our economies are powered. How have technology and innovation been used to cover up the role of a growing energy supply in the last century of rising prosperity? In the midst of discussions between value and labor, where does energy really fit into the equation? Where do we go once we understand the true role of energy in our economy - and will we have the ability to reshape economic policies to be in line with our energy realities?
About Steve Keen
Steve Keen is an economist, author of Debunking Economics and The New Economics: A Manifesto. His new book, Rebuilding Economics from the Top Down, will be released in 2024. He is a Research Fellow at the Institute for Strategy, Resilience, and Security at University College in London. Steve was one of the handful of economists to realize that a serious economic crisis was imminent, and to publicly warn of it from as early as December 2005. This, and his pioneering work on modeling debt-deflation, resulted in him winning the Revere Award from the Real World Economics Review.
