Years of revisions later, I’m thrilled that “A Model of the Data Economy” with M. Farboodi is out in ReStud. Data is an asset, a by-product, fuel for AI predictions, and a means of payment. What does that change about macroeconomics? doi.org/10.1093/rest...

Super interesting! "Data-driven automation" by Maryam Farboodi, Andrew Koh, and Anchi Xia. drive.google.com/file/d/18Fm4...

Congratulations Helene and thank you to Hyun Song Shin for leading us all through turbulent times.

Some of Mamdani's estate tax plan makes sense. Moguls "exchange" one building for another and defer the tax. When they die, most deferred tax gets wiped out. This makes up for unpaid tax. If there's a billionaire exodus? To leave, they'd need to sell, rather than exchange, which would incur tax.

Thanks World Economic Forum for publishing my article on unbundling data and goods. It's a market-oriented approach to privacy policy. The goal is not to prevent using data, but to give consumers choices and get us a better deal. #dataprivacy www.weforum.org/stories/2026...

Federal Reserve Governor Lisa Cook has sued the Trump administration in an effort to overturn the president’s attempt to fire her, launching an unprecedented legal battle that could significantly reshape the Fed’s longstanding political independence. https://to.pbs.org/4lLn4iL

This is a monumental case for American democracy and the health of our country’s economy. The courts must rule in favor of Federal Reserve independence and against Trump’s authoritarian instincts. www.nbcnews.com/business/eco...

#CollectiveCourage: Hundreds of economists from across the country have signed an open letter calling on Congress to uphold Federal Reserve independence. If you’re an economist, you can still sign on: https://docs.google.com/document/d/1oGrUv-_CoeulsLZDt_lyNTPbm9wYCAfiTLm7KMiwgzA/edit?tab=t.0

Straub @JacksonHole2025: Looming debt crisis bc fewer workers, more retirees drive debt to 5xGDP. We can cut retirement, hike taxes. But we can also allow legal, young immigrants. The benefits of immigration are typically overlooked, but are worth years of Americans' income. #econsky

Emi Nakamura at Jackson Hole: Analyzing Taylor rule performance, she emphasizes -- Federal reserve reputation has been a powerful too for keeping inflation in check. "Reputation takes a long time to build up and is quick to destroy." An important warning in modern times. #econtwitter #JacksonHole

@Jackson Hole, Linda Tesar says: Americans moving from state-to-state is declining. But it's not unwillingness to move. Rather, the mix of jobs across states is becoming more similar. We don't move as much because other places don't have much better or worse labor markets. Homogenization. #Econsky

From Jackson Hole, Claudia Goldin says to gov't: If you want more American-born kids, then fund child care, don't deport the nannies and most of all, support gender equality. When men share the burdens, women have more babies. #JacksonHole #EconSky

Historic and well-crafted talk at a critical time in monetary policy history. The feeling in the room reflected the weight of the moment.

Chair Powell just signaled a willingness to cut rates. Bond markets responding strongly now. His argument is that tariffs represent only a one-time price increase, not a real threat of ongoing inflation. Time will tell. #JacksonHole #EconSky

Sitting in Jackson Hole this morning, curious about what Powell will say. The tension is palpable. #JacksonHole #EconSky

Politics and the Federal Reserve do not mix! It's not just bad for the Fed's reputation, it's also bad for the economy. Investors will be less willing to buy US assets if they can't trust the Federal Reserve to do its job without political interference.

NEW: I spoke to a dozen current and formers about low morale at ICE amid the Trump admin's relentless push for more and more arrests. Officers and agents aren't complaining or looking for sympathy but they're facing public anger & political pressure from above www.theatlantic.com/politics/arc...

The word "fringe" is very unfortunate. This short video clarifies why lives depend on these indirect costs cut from government health grants. zuckermaninstitute.columbia.edu/what-are-ind...

When I feel powerless amidst all the crazy, it's helpful to me to just do something. My something was taking the time to talk to NPR about why we should not cut federal data collection. I realize it won't change many minds. But it was something: www.marketplace.org/episode/2025... #econsky #dataecon

Similarly, uncertainty-related terms surged in April as well. Lots of mentions of pulling back on investment plans due to the uncertainty, highlighting the "business planning recession" idea @conorsen.bsky.social coined here: www.nytimes.com/2025/04/20/o...

Striking stat from @kellycnbc.bsky.social on this: The rise in treasury yields since Trump’s tariffs were announced leads to an increase in US debt interest payments that is larger than all the DOGE savings.

Finally some good news! ... Congratulations to Stefanie Stantcheva on the 2025 John Bates Clark award for best economist under 40! I'm humbled to have been part of her selection and inspired by what she has accomplished. #econsky @s-stantcheva.bsky.social www.aeaweb.org/about-aea/ho...

Thank you Steve Kerr! A reminder that we can all stand up in our own way to preserve the institutions we treasure.

How can one person have so much power that their tariff obsession can crash the global economy? How did checks and balances fail so catastrophically?

Tourism tanks, recession risk rises. #econsky

Market chaos: uncertainty cranked to #econsky

The lesson of the "China shock" isn't actually about trade. It's about how hard it is for workers and communities to adapt to rapid economic changes. Now Trump is trying to reshape the global economy overnight, with potentially devastating consequences. #EconSky www.nytimes.com/2025/04/11/b...

Foreigners are afraid to come to America, for fear they’ll be locked up in secret jails. This is going to cripple the U.S. tourism industry #EconSky

Pessimistic consumers cut back on spending. #EconSky #Recession

A thoughtful and inspirational article. A quick read and well worth it.

From the University of Michigan survey: Consumer expectations of future economic conditions among Republicans have dropped notably (though are above year-earlier levels). Independents are back to the low point of the Biden presidency.
