The Unassuming Economist

From a new paper by Nicholas Apergis and Hany Fahmy:

“This paper explores the link between geopolitical risks and energy prices crash risk. Studying energy price crashes is important given the sharp fall in oil prices in 2008 and 2014. The analysis focuses on three energy markets: natural gas, oil, and coal, while it employs two measures: the negative coefficient of skewness and the down-to-up volatility, to construct proxies for crash risks. The period of examination is January 2000 to December 2023, whereas that for coal is January 2010 to December 2023. The study employs a modified version of the smooth transition autoregressive model. The results show that, within the modelling framework, coal and oil crash risks are driven by the cyclical behavior of geopolitical acts, whereas natural gas crash risks by geopolitical threats. Causality tests confirm the prediction that geopolitical tensions cause crash risks in energy markets. The results also confirm that the “Economic Activity Channel” is only valid for energy markets driven by geopolitical threats. Energy market regulators should be concerned about crash risks, given that the energy supply shows cyclical boom and bust cycles in prices and production. Crash risks could also potentially cause a fall in investments required to enhance energy efficiency.”

From a paper by Jeisson Riveros and Muhammad Shahbaz:

“Nowadays, nobody can deny the relationship between economic growth and sustainability; however, the tendency to un-match a linear relationship between those two has acquired the name of “decoupling” economy, which means that the consumption of energy not necessarily has to rise at the same rate of gross domestic product, in order to reduce carbon emissions in a country or certain area. Then this document aims to study the Colombian decoupling, analyzing the economic structure and energy consumption between 1975 to 2021, applying the TAPIO model and the logarithmic mean Divisa index (LMDI) using the KAYA identity as a conversion factor (TAPIO+KAYA+LMDI) to analyze the trends per economical sector. Finding that, the Colombian economy has a predominant status of weak decoupling with randomly switches to strong decoupling, positioning it as a sustainable economy; although this condition is environmentally favorable, under a comprehensive public policy, energy consumption by economic sector can be increased to improve economic productivity and achieve better production levels on the sectors of agriculture, mines, and commerce whose energy consumption according to the data is substantially low.”

“The explosive growth of Bitcoin and other cryptocurrencies has opened up a new front in the broader climate crisis by threatening to offset the progress made in recent years toward decarbonization. For the technology to gain wider adoption over the long term, its proponents will have to get serious about reducing its energy usage“, writes Marion Laboure of Harvard University.

The extensive power requirements in the cryptocurrency mining process, especially of those currencies limited in supply like Bitcoin, have generated a global debate on the sustainability of the process. While China banned the mining of cryptocurrency in September 2021 amidst an already debilitating energy crisis, other countries like El Salvador have adopted other methods like establishing a crypto mining city near a volcano to power the process using geothermal energy. Clearly, the world is divided on the matter. This article explores the issue in greater detail, charts out the environment-revenue trade-off before economies, and explores potential solutions.

From Mark Perry (AEI):

“Tomorrow is Earth Day 2022 and marks the 52nd anniversary of Earth Day, so it’s time for my annual CD post on the spectacularly wrong predictions that were made around the time of the first Earth Day in 1970…..

In the May 2000 issue of Reason Magazine, award-winning science correspondent Ronald Bailey wrote an excellent article titled “Earth Day, Then and Now: The planet’s future has never looked better. Here’s why” to provide some historical perspective on the 30th anniversary of Earth Day. In that article, Bailey noted that around the time of the first Earth Day in 1970, and in the years following, there was a “torrent of apocalyptic predictions” and many of those predictions were featured in his Reason article. Well, it’s now the 51st anniversary of Earth Day, and a good time to ask the question again that Bailey asked 21 years ago: How accurate were the predictions made around the time of the first Earth Day in 1970? The answer: “The prophets of doom were not simply wrong, but spectacularly wrong,” according to Bailey. Here are 18 examples of the spectacularly wrong predictions made around 1970 when the “green holy day” (aka Earth Day) started:

1. Harvard biologist George Wald estimated that “civilization will end within 15 or 30 years [by 1985 or 2000] unless immediate action is taken against problems facing mankind.”

2. “We are in an environmental crisis that threatens the survival of this nation, and of the world as a suitable place of human habitation,” wrote Washington University biologist Barry Commoner in the Earth Day issue of the scholarly journal Environment.

3. The day after the first Earth Day, the New York Times editorial page warned, “Man must stop pollution and conserve his resources, not merely to enhance existence but to save the race from intolerable deterioration and possible extinction.”

4. “Population will inevitably and completely outstrip whatever small increases in food supplies we make,” Paul Ehrlich confidently declared in the April 1970 issue of Mademoiselle. “The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years [by 1980].”

5. “Most of the people who are going to die in the greatest cataclysm in the history of man have already been born,” wrote Paul Ehrlich in a 1969 essay titled “Eco-Catastrophe! “By…[1975] some experts feel that food shortages will have escalated the present level of world hunger and starvation into famines of unbelievable proportions. Other experts, more optimistic, think the ultimate food-population collision will not occur until the decade of the 1980s.”
