Milton Friedman's Cherished Theory - The permanent income hypothesis - Is Laid to Rest Noah Smith

 A new study by Peter Ganong and Pascal Noel shows that consumer behavior is more short term than almost any mainstream model predicts.

 Even the greatest scientists can be wrong. The measure of a science is how quickly it comes to grips with the mistakes its heroes make.

 Noah Smith, Bloomberg 12 January 2017

Pfizer in 2019 sold $20 billion of drugs in the U.S. Its federal tax bill? Zero; Ireland

Trump has already singled out pharma companies and countries like Ireland that reap the benefits of tax-avoidance moves.  Despite its small size, Ireland ran an $87 billion trade surplus with the U.S. last year—larger than any country except China, Mexico and Vietnam. https://www.wsj.com/health/pharma/how-trumps-tariffs-could-upend-pharmas-overseas-tax-strategy-5b8ca758 Is Ireland vulnerable again as the world’s vast shadow banking system starts to crack? Shadow banking is the dog that has not barked during the latest global spasm of financial stress. This is very fortunate, especially for small countries such as Ireland that have bet the farm on this industry. https://englundmacro.blogspot.com/2023/04/is-ireland-vulnerable-again-as-worlds.html Cayman Islands https://en.wikipedia.org/wiki/Cayman_Islands What the heck is happening in the Cayman Islands?
