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.

Somewhat relatedly, GLP-1s are having positive “side effects” as a function of treating obesity on some mental health disorders. Also VA sample in Nature Medicine

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! 📉📈

Our paper is covered today in @washingtonpost.com by @crampell.bsky.social: ➡️ wapo.st/3BSKbXY

As always, comments are welcome!

🚨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.

Whoa, missed this paper when it originally came out last year.

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

The result? Evidence of a "Sales Gene"!

⛷️Ski season is open in Killington! ⛷️

Contemplating the economics of IKON/EPIC pass duopoly pricing and its impact on the distribution of skier welfare. Lot's of trade-offs —demand expansion & variety seeking on one side, congestion on the other.

Who is writing an IO paper about this? #econsky

Good question and hard to tell from the report, which indicates that at least 50% will be premium. Maybe the rest is about rearranging existing seats but that would be stretching the definition of “incremental”

Delta's product versioning and market segmentation approach is a masterclass in second-degree price discrimination under capacity constraints. 85% of new seat capacity will be in premium categories, which currently have 15% higher margins.

Congratulations! And thanks for the quasi-experimental evidence that even with 8x fewer followers, engagement where the sky is blue is amazing—though I’m pretty sure your next method will find a way to disprove my *casual* inference!

What determines the tipping point that triggers a switching cascade?

1️⃣ Network structure+strength of ties
2️⃣ Distributiion of individual thresholds (# of your connected nodes already switched and their centrality)
3️⃣ "Price"+perceived value

Looks like #2 and #3 just tipped for me🌀 #Bluesky #Econsky

Let’s try this! First #EconSky post 👍

Norway's (population 5.4m) sovereign fund is similar size to that of China's and owns a staggering 1.5% of the global stock market.
