The ESRI has withdrawn a paper which showed that 4 out of 10 working families would be financially better off on the dole.
The Government think tank has said the document was a "work in progress document" and represented un-refereed work by researchers who are solely responsible for the content and the views expressed.
It has taken the unprecedented step of withdrawing the paper because the underlying analysis in it needs major revision and overstates the numbers of people who would be better off on social welfare.
The ESRI has said that it is concerned that the public could be misled by the content of the paper.
