The proudest moment of my life was my admission to
Harvard in 1976. Today I am deeply ashamed. @harvard.edu must revoke Summers' University Professorship. His holding the school's highest honor debases the university and is an insult to every woman and person of color in the academic community.

A senior academic using mentoring as leverage to obtain sex is a contemptible abuser of power.
Summers conferred with Epstein frequently about how to extract sexual favors from a Harvard econ grad (AB '04, PhD '09)

The grad is from China

Epstein and Summers referred to her by the codename "Peril"

Racism and sexual exploitation in one efficient package

The Crimson is doing great work with this story. Heckuva kicker here:
"The final messages, dated July 5, 2019, show Summers still in regular contact with Epstein....
The thread ends at 1:27 p.m.
Epstein was arrested the next day."

Else they'd still be emailing!

Maybe, just maybe, don't treat women in your profession, especially women in a mentor/protege or supervisor/employee relationship, as part of your potential dating pool?
If women are underrepresented in STEM, it's at least partly because men like this offer mentoring, then embarrass themselves by assuming their mentees must be into them, then decide the best solution is to cut ties, which sends the signal to other faculty that the mentee must not be good enough.
The emails have Summers reporting to Epstein about his attempts to date a Harvard economics student & to hit on her during a seminar she was giving.

If Marshall's interpretation is right, this is a grave departure from the professional standards of Economics. I have written to the relevant Harvard administrators. #EconSky

During Jim Crow, everything from restaraunts to stores to hotels to pharmacies to gas stations required making safe choices. They shaped every trip a Black person made. We document that history, and you can add your story to it here #CommunityMap: greenbookproject.osu.edu #GreenBookProject #EconSky

The most typical car loan went from 3 or 4 years to 6 or 7 over the time car durability approximately doubled.

Perhaps too long: First-owner holding periods are significantly shorter than that. Still, a reasonable expectation that the collateral will be there if there is a default.

Never thought of using classes. As Director of Undergraduate Studies, I had a lonely-hearts advice practice for young men (True rumor circulated that I had married before graduation.) Most common and most obvious advice: "Have you considered asking her out?"
Coupling this, fertility that.

Why don't you academics actually do something about it?!? 😂
