Budget Resolutions and Economic Situation

The Secretary of State is a most cerebral Minister, so I wonder whether he can help with a problem that I am grappling with. One way in which the north has competed with the south in the past has been through lower wages. I am not saying that that is right, but how will the living wage impact on it? When employers increase wages, they normally do so as a result of an increase in productivity. If there is a living wage imposed by the state, how will we avoid increased unemployment or lower productivity —or both?
