Bernanke seeks data, spurns Greenspan quick fix

Alan Greenspan trusted his instincts. Ben Bernanke trusts the MAQS.

For the past several days, the MAQS - a group of analysts in the Federal Reserve's Macroeconomic and Quantitative Studies unit -- have run a series of what-if scenarios on the US economy that will play a critical role in next week's interest-rate decision, according to a report on the website of Bloomberg.

"The simulations will supplement the forecast handed to policy makers at the start of their September 18 meeting, and may determine the size of the rate cut almost universally predicted by Wall Street economists," the report said.

Bernanke has championed the team's work since becoming Fed chairman in 2006 because he wants to sift through models, projections and anecdotes before coming to conclusions. His approach contrasts with that of predecessor Alan Greenspan who relied more on his own reading of conditions, and as a result probably would have cut rates to insure against a recession long before the Federal Open Market Committee (FOMC) gathering.

The FOMC will next week lower the overnight lending rate between banks to 5% from 5.25%, according to the median forecast of economists surveyed by Bloomberg. The reduction would be Bernanke's first and may be followed by at least two more before year-end, the report said.
