NEW YORK, June 2 (Reuters) - Clinton-era Securities and Exchange Commission Chairman Arthur Levitt has signed on as an advisor to Goldman Sachs Group Inc (GS.N: Quote, Profile, Research), the Wall Street firm said on Tuesday.

The role, in which Levitt will provide Goldman with strategic advice in a number of areas, adds to other industry positions he has taken since leaving the SEC -- the U.S. securities industry watchdog -- in 2001.

Levitt, 78, also draws a paycheck from private equity group Carlyle [CYL.UL] and financial information provider Bloomberg. He declined a request for an interview.

"He will be a good source of advice," said Lawrence White, an economics professor at New York University's Stern School of Business. "He knows a lot of people in government, so it won't hurt on the lobbying side. Who knows what they are paying him? But I'm sure they are getting their money's worth."

Levitt was the longest-serving chairman of the SEC, having led the commission starting in 1993, regulating the industry during the froth of the Internet boom.
