Seeking to allay businessmen's fears about President Carter's economic policies, two top administration official's yesterday promised that the President soon will make a major statement on the economy.

The pledge came from Commerce Secretary Juanita Kreps and special trade negotiator Robert Strauss after they met with the Business Councilman organization of corporate chief executives.

Hours earlier, the council had issued a pessimistic economic forecase, complaining that a major cause of pessimism in the business and financial community today is that the administration has not spelled out a consistent economic philisopy or program."

Meeting with reporters after they talkedwith the businessmen. Kreps andStrauss indicated that the President is aware of the needto clarify his stand on basic economic issues. "I would hope he would do it very soon." said Kreps.

As one Business Council member put it"The President needs to explain what he believes is the role of business in the society."

The council's chairman,John deButt, chairman of American Telephone & Telegraph, praised the Carter administration's responsiveness to business views in a speech in Richmond earlier this week. But deButts yesterday joined the lament over uncertainities caused by the lack of what thecouncil called "a definitive statement of the administration's long term economic game plan."

Among the uncertainties cited by deButts arethe administrative's tax plan, which has been in the works for months, and a strategy fordealing with foreign competition of troubled industries, particularly steel. Steel industry executives discussed that issue with Carter and other high-level administration officials, including Strauss, on Thursday.

Aslo unclear is the question ofwhether a tax cut is needed next yearto spur the economy. Themixed views of businessmen themselves on that issue were expressed here today.
