The responses the newspaper got were not very helpful:
"We are currently in the process of reviewing the IBO's assertions as to the economic benefits of Atlantic Yards," said Bruce Bender, an executive vice president of governmental affairs for Ratner.
"We will not comment further until we have had sufficient time to review them."
Note that Bender called the IBO's conclusions "assertions" but Forest City Ratner calls the previous report by the IBO a "study."
NYC EDC response
As for the New York City Economic Development Corporation, it repeated the argument it made to WNYC:
...by only analyzing the arena - and not the 16 residential and commercial towers also proposed for the site - the IBO had released inconclusive information.
"In light of new conditions, the city is updating a cost-benefit analysis, and any decisions related to the project will be informed by this revised analysis with the goal of ensuring a significant net positive fiscal impact to the city," said EDC spokesman David Lombino.
Well, there's little evidence the rest of the project will be built in a timely fashion, if ever, so the arena is a legitimate, if incomplete, subset, even though Lombino is correct in suggesting there should be a full analysis.
