Thank you for asking me how I am doing. I am not well. Here is why: ▪️The area affected by the Turkish/Syrian #earthquake is the size of the entire United Kingdom. ▪️ In #Türkiye alone, 16,000 people are dead and over 200,000 under rubbles, probably dead or dying. 👇🏻 – at Oxford, England

This is a great paper and well-executed study on the impact of antitrust intervention on platform complements. I recommend a) reading it, and b) taking ten seconds to vote for it at the link below

Honored to share that my paper with @rkatila1 on #platform #antitrust is a finalist in the Economics category at the #AntitrustWritingAwards. There is a Reader's Choice Award for which we would appreciate your support! You can vote for us here: bit.ly/ThatchenkeryKatilaAWA

Is there an economic reason billionaires end up owning sports teams, vs other (conglomerate) owners? Or any recommended reading on the economics of pro sports?

Thrilled to see our phenomenal 1st year PhD student Hilary Mahar crush it in her very first academic conference, delivering virtually to a packed (in-person) room at the @USASBE "Driven by Dreams" entrepreneurship conference @BUQuestrom

I love this story, as it highlights how even a simple change (it’s just a box!) can actually represent a radical reframing of an idea, and can generate controversy to match
Kate Raworth@KateRaworth30 Oct 2022
Replying to @KateRaworth
Such a radical redrawing meets a lot of resistance - as Daly discovered while working at the World Bank in the 1990s. Here's a great story he told about commenting on drafts of the WB's major 1992 report Development and Environment. Some pictures turn out to be too powerful...

While I design most of my own exercises, sometimes classics like the Marshmallow Challenge really are the best. This year, 16/17 teams ended up learning the hard way (and will remember) about failing to test hidden assumptions (spoiler: marshmallows are really heavy)

As some of you know, I started a major research program on pandemic-era grassroots innovation. I've got a talk this weekend - if you're in Boston, c'mon by for inspiring stories of folks who stepped up, and thoughts about how we can be ready for the future @BUQuestrom @BU_Tweets

Heyo! What a cool event. 9 amazing students turned out in the rain to make miniature dorm-room #corsirosenthalbox air purifiers, play with tape, and learn about user innovation. Thanks to the amazing @innovateBU BuildLab for hosting! @bu_tweets @jonlevyBU @BUQuestrom
