AbstractThis paper attempts to uncover the effects of a UK welfare‐to‐work programme on individual wage growth by exploiting an expansion to this welfare programme. The conventional wisdom is that such programmes trap recipients into low‐wage, low‐quality work – this comes from the simple argument that the ‘poverty trap’, which a wage subsidy for low‐income workers induces, reduces thebenefitsto investments, such as on‐the‐job training, and so reduces wage growth. In fact, a wage subsidy will also reduce thecostsof, at least, general training because we would normally expect workers to pay for their own general training in the form of lower gross wages. So a wage subsidy is a way of sharing these costs with the taxpayer. Thus, the net effect on wage progression depends on whether it reduces costs by more or less than it reduces the benefits.
