An announcement that is as personal as professional:
18 months ago, we started collecting online prices in real time to track how Liberation Day tariffs were feeding into inflation.
A lot has happened since. The BLS commissioner was fired. The longest government shutdown in US history meant CPI wasn’t published for the first time. And the case for an independent measure of inflation became much stronger.
What started as a tariff inflation tracker has since grown into something much bigger:
The Bloomberg Price Project (BPP), our attempt to build the US CPI from the ground up using alternative data.
Today, BPP covers 87% of the CPI basket, across both goods and services (more new data will be added in coming weeks). Every month, we collect millions of prices from card transactions, e-commerce sites, grocery stores, pharmacies, rental listings, corporate data, Bloomberg Terminal market prices and government records. And more data are coming.
The payoff is detail. Official CPI data let you drill down to categories such as “uncooked beef steaks.” BPP goes much deeper — breaking the CPI basket into almost 700 line items, compared with roughly 200 in the official data.
Brought to you by: myself, Troy Durie, Daniel Ripperger-Suhler, Joshua Danial and Scott Johnson from across Bloomberg Economics.
Explore the Bloomberg Price Project at BECO MODELS BPP <GO>, or download the data at ECAN US BPI <GO>.
I believe the paywall on Bloomberg.com is coming down briefly so you can read this without a subscription (but you should subscribe!)

New Anthropic research: How AI agents shape experts' judgment calls
When experts delegate work to an agent, do they still make the key decisions? We tested this in a randomized trial with 50 professional data analysts.
Northwestern’s RISEI Lab is hiring a postdoctoral economist to use administrative data to study the intersection of disability policy, labor, education, and technology. aeaweb.org/joe/listing.php?J…

Hago este hilo porque, pana, acá no se aprende. Ya están otra vez en modo "It's so over". Por más que se les advierta, solo saben asumir un optimismo jactancioso y panglossiano o una lloradera lastimera. Todo por no aceptar que no hay futuro seguro. xitter.cf/AAAD25/status/20719890…
Temo que cualquier opinión que se tenga sobre #Venezuela sin haber leído el famoso “biggest oil deal”, es apresurada y especulativa. Para empezar, USA no tendría ningún interés en cambios institucionales hasta que tengan una recompensa esperada. Hay mucho por ver.

Many people probably don't realize how high the bar is to complete a PhD in economics. But let me explain for their benefits.
A proper PhD program makes you work about 50 to 60 hours every week for a year before your start focusing almost all your time on research. If you clear all your classes, you get to take qualifying exams: 4 hours long exams on micro theory and macro theory, each covering the entirety of 3 graduate level courses. If you fail those exams, you're out.
And the exams are extremely hard to pass. The problems are not broken down, so you do not have any hints along the way and a mistake can rapidly snowball into cost you 20%. And you basically do not have any time to hesitate. It's so demanding that smart people who prepare for it routinely fail.
Have you ever seen the face of students who failed those exams? Because I have. These people were smart. I was around them for a year. Some of them studied physics and mathematics before falling in love with economics. And they really wanted to do an economics PhD. They showed up every weekend to study. But it wasn't enough -- and that's not Chicago or Harvard where it would be even harder.
So, I am going to say something many people will dislike: most people would fail to complete a PhD in economics even if they gave it their best shot. It's just that hard.
Paul Krugman and Joe Stiglitz ran circles around people who did this for years... I know it's tempting to call them names if you dislike their politics, but there is no question these are unusually smart people.
Fell in love with my new RA, Claude. It organized my folders, files, research, job market docs, created READ ME files, and even fixed code paths in files that are currently Schrodingering in-between folders. Can't stop thinking about The Measure of a Man.

broad support across latin america for us action in venezuela.
maduro was extremely unpopular, exported problems across the region, and security is a top concern for most everyone.
Last week I had the honor of representing Venezuela at the Korean Prime Minister Cup in Taebaek-si, securing 2 wins in 7 rounds in one of the toughest international Go events
Losing is rough, but I won against opponents 2-4 ranks above me, breaking through a long-lasting plateau

Fantastic debate about free trade at the University of Tennessee.
Earlier this week, economists @cowenconvos and @rodrikdani sparred over free trade @utknoxville, igniting bold ideas. At the Baker School, a #YouMightBeRight mindset fuels civil, solution-driven conversations. #FreeTrade #PolicyDebate #BePartoftheSolution

Join us on Thurs 4/10, 3:30PT in AL 660 or at sdsu.zoom.us/j/83130836835
Es posible que las deportaciones que estamos viendo sean prioritarias y "targeted" porque los deportados tengan prontuario. El Memorandum Mayorkas de 2021, exigió a ICE concentrar sus esfuerzos en deportar terroristas y criminales pero considera factores mitigantes.

Mayorkas pide concentrar las deportaciones en personas con prontuario. Pero agrega que incluso en esos casos deben hacerse excepciones dependiendo de la edad, salud mental, tiempo en USA, el impacto en familiares, etc.
