"David M. Kennedy, the next Secretary of the U.S. Treasury, yesterday prescribed a ?ÛÏvery tight"" Federal budget as the cure for inflation?ÛÓa remedy that he concedes will produce ?ÛÏsomewhat higher"" unemployment in the Nation.</br></br>Kennedy, who will step down as board chairman Chicago's Continental Illinois National Bank and Trust Co. to join President-elect Nixon?Ûªs Cabinet, appeared before the Senate Finance Committee</br></br>Inflation, he said, is the central problem of the economy and ?ÛÏI think it's very important that we have a very tight budget on the expenditure side.?Û? ?ÛÏThe effort would be to take the inflationary steam out of the economy with a minimum of increase in unemployment,""</br></br>Kennedy said. But, yes, he added, unemployment would ""surely be somewhat higher than the present rate.""</br></br>How much higher is an impossible question at this point, the Secretary-designate said. ""I don't like to get into percentages because you?Ûªre dealing with human beings,?Û? he said."
