Authors also supplement empirical analysis w/some interviews of key scientists. Will interrupt my recapping to also plug this excellent new yorker article on same topic (and here's a graph of the key productivity effect!) newyorker.com/news/news-desk…

1/ Recently finished "The Genesis of Technoscientific Revolutions" by Narayanmurti and Tsao. The book lives up to its grand name! It feels like a (fuzzy) image of the elephant that is "how research works" where everybody else is feeling a snake or a tree. BOOK REPORT THREAD🧵

Can't believe this paper is finally out!😍 It has been six years in the works - almost spanning my entire career😅 Phew. What did we do? Why did it take so long? And is it worth the read? 🙏A personal (long) thread below👇🧵 1/10

The Review of Economic Studies @RevEconStudies

@TTorslov, @LudvigWier and @gabriel_zucman estimate that 36% of multinational profits are shifted to tax havens globally. U.S. multinationals shift twice as much profit as other multinationals relative to the size of their foreign earnings. https://t.co/XrXjdw2vfq https://t.co/fkvTo38XbN

New working paper about ghost firms! While this sounds like Halloween, it's actually about a sophisticated form of tax evasion common in many countries: use of fake receipt from fake firms, with which firms claim false deductions to lower their taxes. Short summary thread: 1/n

NBER @nberpubs

Around the world, “ghost firms” sell fake receipts to real firms to enable fraudulent tax deductions: how they work and how Ecuador found an effective policy against their use, from Paul Carrillo, Dave Donaldson, @DinaPomeranz, and Monica Singhal https://t.co/pkhjXNd5DC https://t.co/yzhwNiPimY
