Lots of people think Pretty Woman is an unrealistic depiction of the American dream and I'm afraid I must agree.

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.

Once we acknowledge it, we can make progress toward understanding the role of context, endogenous responses, etc. One of my favorite papers to provide clarity of though in this way is this one.... www.jstor.org/stable/35901...

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.

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.

Delta airlines has been doubling down on premium passengers

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
