The Corporate Tax Burden: Facts and Fiction by Aswath Damodaran, April 20, 2021. This article is an excellent data-driven overview of corporate tax rates in the United States and around the world: “The Biden Administration’s $ 2 trillion infrastructure plan, announced with fanfare a few weeks ago, has opened up a debate about not only what comprises infrastructure, but also about how to pay for it. Not surprisingly. it is corporate taxes that are the primary vehicle for delivering the revenues needed for the plan, with an increase in the federal corporate tax rate from 21% to 28% being the central proposal. I will leave the debate on what comprises infrastructure to others, and focus entirely on the corporate tax question in this post.” (Musings on Markets)

Greenlight Capital’s Q1 2021 Letter, April 15, 2021. David Einhorn’s Greenlight Capital letter is full of interesting observations on topics including the massive stimulus spending over the past year, the Federal Reserve’s monetary policy and prospects for inflation, recent action in GameStop and other meme stocks, and the crazy $100+ million valuation of Hometown International, a company that owns a single deli in New Jersey with sales of less than $14,000 in 2020. “The pastrami must be amazing.” (Greenlight Capital Letter posted on

A Failure of Texas-Size Proportions by Katherine Blunt and Russell Gold, April 16, 2021. A February cold snap crippled Texas with long blackouts that affected two-thirds of its residents and resulted in at least 111 deaths due to causes including hypothermia and carbon monoxide poisoning. The Texas electricity market has been deregulated for nearly two decades and has mostly seemed to achieve its objectives. However, failure to winterize equipment caused catastrophic fragility. Now the state government is pondering how to fix the grid. Berkshire Hathaway has proposed a $8.3 billion plan but seeks a 9.3% rate of return on the investment. However, critics have characterized a guaranteed rate of return as “anathema” to free market principles. This article provides a good overview of the situation. (WSJ)

long feedback loops by ava, April 16, 2021. This article will resonate with anyone who has experienced the addictive nature of social media. Platforms such as Twitter and Facebook provide very short feedback loops. You can post a random thought on these platforms and instantly get feedback especially if you have a large number of followers. Sometimes, short feedback loops are helpful for acquisition of basic skills and knowledge, but proficiency in any field requires deep work and longer feedback loops. For people addicted to the dopamine rush of instant feedback, adapting to activities with longer feedback loops can be a challenge. (bookbear express via Substack)

The Self Educating Child by Mr. Money Mustache, April 18, 2021. The pandemic has been a traumatic experience for children thrust into remote learning and isolated from friends. Although it doesn’t seem to be common, some kids have been able to actually accelerate their pace of learning by leveraging the limitless information available online. One such example appears to be the son of Mr. Money Mustache (MMM), a well-known personal finance blogger who generally lives a self-sufficient lifestyle. After a year of learning online, MMM’s son will not return to high school and may never pursue a college degree. I’m skeptical that this approach will work for most kids but I’m including the article in this week’s newsletter because it has a list of useful online resources for readers with children. (Mr. Money Mustache)

Markov Chains by 10-K Diver, April 17, 2021. This is a great Twitter thread on probability. It is not uncommon for the intuitive answer to a question involving probability to be dead wrong. Rather than trust our intuition, it is better to think through problems in a systematic way, as the author describes. It seems like Twitter threads are replacing blogs for many writers. 10-K Diver has a website linking to a many worthwhile Twitter threads. Since joining Twitter in April 2020, 10-K Diver has attracted over 123,000 followers. (Twitter)

Financial Bubbles of Historic Proportions, February 26, 2021. “The balance sheet of the Federal Reserve continues to surge at an unprecedented rate, up 83% y/y to a historic level, $7.59 trillion at the latest count. According to our Wealth Track podcast guest, financial historian, and long-time market observer James Grant, interest rates, the “central pricing mechanism for financial markets” have been pushed to artificially low levels by the Fed’s policies which have created numerous market bubbles. He cites Bitcoin as one of the most extreme examples.” (Consuelo Mack Wealth Track) h/t
