@leecoppock and Charles Holt of @UVA, Cathleen Johnson of @WVUEcon, and Madison Smither of @Kennedy_School develop a classroom experiment that implements a transition from a “common field” with shared harvests to private parcels. #Jamestown #experiment https://t.co/gTKRDso1ZC

Japan is SO screwed. https://t.co/ZYse7t36uS

And S. Korea may be worse.

I hope Paul Ehrlich is enjoying the deepest circle of Hell.

Hey Jeremy, I am with you on this, it is a good point and data centers are definitely helping me. But I think you simplify too much here, even for twitter. Marginal analysis seems key, given the scale of the current buildup for AI. Many people believe that MB>MC for data centers in the past (which gets them all the luxuries you cite), but not for the current massive buildup.

Today the Trump administration finally begins returning more than $166 billion (plus interest) collected from the tariffs the President imposed starting last year.

The Supreme Court struck down those tariffs two months ago.

The dream of China surpassing the U.S. as the world’s largest economy is fading. In 2021, China’s GDP was about 78% of the U.S.; by 2024, that share had fallen to roughly 64%, back to around 2017 levels, with the gap between the two economies doubling in just a few years.

@UVAMensHoops @CarterLang_23 Carter is a great student, basketball player, and incredible young man. We are fortunate that he is on our team and that he is an Economics major.

milei putting up some extraordinary numbers: argentina's inflation went from nearly 300% to below 40%. gdp up 4.4%.

[Lee Coppock @leecoppock]

@PrestonBrashers You are probably right about that. But your initial point is silly when you do not account for inflation.

Paul Ehrlich wrote that “hundreds of millions of people are going to starve to death” during the 1970s.

The actual number of people who died in famines that decade: <4 million.

It was <2M in the 1980s, and <1M in the 2000s.

The average person today has more food than ever.

Hahaha “premature.”

[John Aziz @aziz0nomics]

Wrong.

His predictions proved wrong.

They were not premature.

They were wrong. His understanding of the world was wrong. Faulty. Unrealistic. False. Falsified.

Great visualization. I have not confirmed the accuracy but this passes the sniff test.

@byHeatherLong This may seem picky but it leads to confusion regarding the causes of inflation, which is the growth rate of the overall price level.

[Lee Coppock @leecoppock]

@byHeatherLong @byHeatherLong, you always do a nice job keeping up with and posting important macro data. But changes in relative prices are not the same thing as inflation. Inflation is the 2.4 number.
