Treasury Secretary John Whitehead has told MPs that it has done some work on why there are negative views about selling state-owned assets.
Mr Whitehead was appearing before the Finance and Expenditure Select Committee to discuss its work, following the Budget.
He said as the Government's position was for state assets to be held, it had not been asked to do any reports on privatisation.
But he said Treasury had to be prepared for options that might come up.
Mr Whitehead said this was similar to work Treasury undertook in 1999 on raising the top tax rate, before the the new Labour Government came in.
