🚨Closing out 2024 with a new paper with @hristakeva.bsky.social and @leofeler.com: How GLP-1 medications like Ozempic are reshaping food demand and changing the rules of the game for the food industry.
My colleagues at Cornell simulated various tariff and retaliation scenarios proposed by Trump on China, Canada, Mexico, and the rest of the world, analyzing impacts on trade flows, sectoral output, real GDP, etc.

Pepsi facing an FTC lawsuit shows the impact of big-box retailers like Walmart shaping supplier contracts. My colleague’s @hristakeva.bsky.social research shows that smaller retailers, without this leverage use product selection and supplier replacement threats as tools to negotiate terms.

Feeling a bit surreal—just heard that JP Morgan and Morgan Stanley issued equity research notes on our paper with
@hristakeva.bsky.social and @leofeler.com
This is probably the closest my research will ever come to influencing markets! 📉📈

Do I know any researchers who have done research on biomarker data in the HRS survey, ideally blood-based biomarkers, e.g. of ageing?
If so, very curious about sample size issues, particularly in case of running similar analyses in smaller countries.

While this has happened many times before with automation and productivity gains, it makes me think about the shape of the marginal rate of substitution between labor and leisure—as getting more leisure gets cheaper, we might not actually want all of it, even at the price of zero.
82% became less happy w job, including those who became more productive
This highlights inconvenient possibility: productivity gains may be welfare reducing even w/o mass displacement
I'm not first to say this, but meaning needs to be more central to research on labor market implications of AI

When it comes to Russia, always listen to the Baltics (and Poles)…
The Syrian example shows that Russia can be kicked out and will go home. The Baltics were right – the West is strong enough to win. We don't need to fear "the Bear" in Ukraine or anywhere else he is causing chaos.

This paper studied 117 salespeople, linking DNA with key performance metrics like revenue, opportunity recognition, and effort.
