Artificial Intelligence: To Infinity & Beyond!

May 5, 2026 4 min read paid

Before the Age of AI, economists were taught that there are only three factors of production, namely, Land, Labor, and Capital. The job of economists is to optimize the allocation of these scarce resources to maximize output (i.e., real GDP). Now, economists should recognize that there is a fourth factor of production, namely, Data. This resource is unlimited. But until AI, it wasn't very useful because it

Today, the US launched Project Freedom, deploying 15,000 service members and over 100 aircraft to escort stranded commercial vessels through the Strait of Hormuz. The first two US-flagged merchant tankers were successfully escorted this morning. However, Iran struck the UAE's Fujairah energy hub and a UAE oil tanker and damaged residential areas in Oman. US forces destroyed six Iranian small boats and intercepted multiple missiles and drones.

The Roaring 2020s Express Train

Apr 30, 2026 5 min read

Why is the stock market continuing to make new highs? It's doing so because corporate earnings are doing the same, as the economy continues to speed along without stopping for a recession. The latest batch of data certainly drove the stock market higher today, confirming that we are still riding the rails on the Roaring 2020s Express. Nothing seems to stop or derail this train.

No More Mr. Nice Guy

Apr 29, 2026 4 min read paid

We will miss Jerome Powell's chairmanship of the Fed. He is a nice guy. He did the best that he could as Fed chair from February 5, 2018, through May 15, 2026, when his term as chair expires. Nevertheless, he said he intends to remain a Fed governor for now. He can do so until his term on the Board of Governors expires on January 31, 2028. President

Powell's Swan Song

Apr 28, 2026 4 min read paid

Tomorrow at 2:30 p.m., Jerome Powell will sing his swan song. That will be his last press conference after the latest FOMC meeting. The Senate Banking Committee is scheduled to confirm the nomination of Kevin Warsh to replace Powell tomorrow. The Senate could move to a final vote shortly thereafter. Powell will likely explain why the FOMC is unlikely to lower the federal funds rate any time soon.

Apr 23, 2026 4 min read paid

President Donald Trump may have to write a sequel to his 1987 book, "Trump: The Art of the Deal." It's hard to make a deal if you kill your opponent. He said that about Iran today again: "They’re all messed up. They have no idea who their leader is... We took out, really, three levels of leaders... So they have a hard time figuring

Warsh, Rinse, Repeat

Apr 22, 2026 5 min read paid

We are Fed Watchers. In his Senate Banking Committee hearing yesterday, Kevin Warsh suggested that under his leadership, we might have less to watch. He advocated ending current "forward guidance" practices, which means no more quarterly Summary of Economic Projections, including the Dot Plot (chart). He suggested that a press conference after FOMC meetings should only be held when there is "important news" to deliver, rather

Power Vacuum In Iran Isn't Fazing US Economy

Apr 21, 2026 4 min read

What if the US won the war, but Iran can't surrender because no one is in charge over there? To make a deal, President Donald Trump needs someone to deal with. He was hoping to strike a deal this week in Islamabad, but the Iranians declined to meet because they are too busy fighting among themselves. Indeed, Trump, today, said that he extended the ceasefire because "the

Happy days are here again! The S&P 500 and Nasdaq rose to record highs today, which just happens to be tax day. What's all the excitement about? The AI bubble hasn't burst, so far.

The S&P 500 is now up 1.3% since Friday, February 27, the day before Gulf War III started (chart). So as far as the stock market is concerned, the war is over until further notice.
