"Some people left their economics notes on the plane. Can Martin Feldstein, Lawrence Summers, and Jeff Liebman please come to gate C10 to retrieve your economics notes?"

On Tuesday night, that announcement came over the loudspeakers at Dulles Airport in Washington, DC. The Harvard World Model UN team, on their way back from Sydney, Australia, heard it over the intercom while changing planes at Dulles.

"The entire team thought it was quite hilarious," said Damon Y. Meng '13. After hearing the announcement, Meng posted it on Facebook, where it received 159 "likes."

Alas, upon further investigation, the famed economics professors were not the ones to leave their notes on the plane. It turns out that the notes belonged to Joshua C. Zhang '14, a junior with the World MUN group enrolled in Harvard's Economics 1420: American Economic Policy, a class taught by all three professors.

So much for the future of economics being left on an airplane.
