Here is an article in The Crimson, with many interesting bits, including about Raj Chetty. In turns out space is also a problem, even back in the mid-1980s I thought Littauer was not impressive. It has not improved:
Economics faculty also say that the kind laboratory work common in modern economics—and exemplified by Chetty’s work on government policy—require physical space that is lacking in Littauer and scattered around campus.
“You need infrastructure to run the types of projects he is running,” Antràs said.
Bernheim said Stanford was working “on much closer collaboration and integration” between its economics research buildings to provide adequate space because of Chetty’s arrival and other new hires. He would not comment on the specifics of Chetty’s hiring package, including any lab space he may receive.
And of course, Littauer is old. It hasn’t undergone a major renovation in decades and lacks a functioning air conditioning system.
Whether there are plans to renovate Littauer is uncertain. FAS Dean Michael D. Smith would not comment on any plans to add space to the building, though he noted that conversations about department space across FAS are ongoing.
Even more, the Fine Arts Library, which moved temporarily to Littauer in 2007 during the renovation of the Fogg Museum, compounds the problem of tight space in the building.
University professor Jerry R. Green said the move “pained” him and that now many books used by the Economics department are housed in the Harvard Depository.
