Asst prof of strategy & innovation @BUQuestrom. I like building things, and I study how people build things. On another site at

My resolution last semester was to make my course materials free for students. Here's what I did.

[Douglas Hannah @dphannah]

Heyo Twitter friends. Ping me if you're interested in joining another site - I've got extra invites I'm happy to share. And/or find me at https://t.co/JfCWlvtp6E

[Pinar Ozcan @profpinar]

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.

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

[Sruthi Thatchenkery @thatchenkery]

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: https://t.co/khgwKbjR3y

@paulgreenjunior That's even more interesting! To promote long-term stewardship? To signal that this isn't just about $$?

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?

Jeff Bezos has said he would sell the Washington Post to buy the NFL Team the Commanders

[Douglas Hannah @dphannah]

@k_mcelheran Oh my goodness yes. The new PC fan / LED combos are so space age (and quiet, and awesome).

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

[Douglas Hannah @dphannah]

@mah_kaa @k_mcelheran @InnovateBU @BU_Tweets @jonlevyBU @BUQuestrom @klakhani @mah_kaa The technology is the same as a commercial unit, but cheaper and typically far higher throughput. The last part makes the use case slightly different; the logical application here is in crowded social spaces like classes where a small unit would have little impact

[Douglas Hannah @dphannah]

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

[Douglas Hannah @dphannah]

@k_mcelheran @InnovateBU @BU_Tweets @jonlevyBU @BUQuestrom @klakhani The current movement was launched by two air quality experts re-inventing or rediscovering this approach early in the pandemic (hence "Corsi-Rosenthal box"). It then scaled through the community. So overall, I think its a bit "user", a bit "low cost", and some "grassoots" :-)

[Douglas Hannah @dphannah]

@k_mcelheran @InnovateBU @BU_Tweets @jonlevyBU @BUQuestrom @klakhani So folks have been making filter boxes for years for use in wood shops, smoke zones, etc. I see this as a classic "users innovate to meet own needs b/c existing products don't work" a la von Hippel, etc. 1/2

[Douglas Hannah @dphannah]

@CorsIAQ 95 made for @YWCACambMA @BayCoveMA @URM @OnTheRiseInc and other recipients in MA and CA, w/ @teetwochan

[Douglas Hannah @dphannah]

@thatchenkery @rkatila1 Congratulations both! This is a wonderful paper.

[Douglas Hannah @dphannah]

This is very cool. I’m honored to be included in @PoetsandQuants’ Best Undergrad Professors list. Thank you to all of my students, mentors, and colleagues who nominated me and supported me along the way. I'm grateful to do what I do.

[Questrom School of Business, Boston University @BUQuestrom]

BU Questrom Professor Douglas Hannah is one of @PoetsAndQuants top 50 undergraduate professors of 2022. Congrats on a well-deserved honor! https://t.co/vDhGx9LcWC @dphannah

[Douglas Hannah @dphannah]

@Ao_JingNing Congratulations! This is wonderful.

[Douglas Hannah @dphannah]

@abhishekn That would actually be a very fun exercise

[Douglas Hannah @dphannah]

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 @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...

[Douglas Hannah @dphannah]

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)

[Douglas Hannah @dphannah]

@k_mcelheran @BUQuestrom @BU_Tweets Link to talk! https://t.co/VcHqFDFwP3

[Douglas Hannah @dphannah]

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

[Douglas Hannah @dphannah]

@k_mcelheran @BUQuestrom @BU_Tweets Yes - I COMPLETELY agree. This is not live but it will be recorded; will follow up with a link.
