I like math, technology, data, all things digital, finance, world cultures and education. Join the discussion!

Why is education the only purchase where we’ve decided it’s okay for the provider to demand full income and net worth info in order to execute on a price discrimination strategy?

@bgurley I don’t think auditors lowered rates with the advent of spreadsheets. The per-employee productivity increased, and they started taking on more scope. This also coincided with the growth of their advisory and consulting practices. In aggregate the firms got bigger.

@adamtirapelle Is there a path that doesn’t require an individual writing an 8 figure check? I’d love to see UCLA or Cal Berk pick up the program, though maybe it’s another way? What are SF State, SLO and Humboldt doing right that we can replicate?

Not smiling cause I had just tried to choke him but his neck arm barred me.

@CardWrestling @aden_andstill That’s one way to say “You got my seed wrong”

Never forget when Sugar Shane Griffith put 11 @GoStanford sports on his back and won a National Title and 5 years ago today and they were all saved! #NationalTreasure

@EconTalker They make my Mondays. I appreciate how you made the most of the format, while not staying narrowly constrained to any one niche.

[Michael Rosen @DataAndMath]

@rockreax @accnetwork @shawnkenney59 Your enthusiasm is contagious, and it’s clear you’ve done your homework. Really appreciate what you’re doing for wrestling and the ACC.

@adamtirapelle This is just boys? What are the totals just for wrestling? I’d guess 800 schools have boys team and 600 girls, with 25000 boys and 8000 girls wrestling?

Tight funnel!

[Michael Rosen @DataAndMath]

@adamtirapelle Big shame. A cursory look suggests it was under $400K/yr.

Cignetti looks like the substitute teacher who actually made you work. “Aw, shit, we got Mr. Cignetti!” Then, 20 years later, you realize he was better than your regular teacher.
