HC Deb 20 March 1996 vol 274 c193W
Mr. MacShane

To ask the Chancellor of the Exchequer what is the average annual cost to the Treasury in lost taxes for every 100,000 additional persons unemployed. [21439]

Mr. Jack

No accurate estimate can be made of the cost to the Treasury in lost taxes for every 100,000 additional persons unemployed. Any such calculation is highly sensitive to the assumptions on which it would have to be based.
