There is a heated debate in many European countries about a move towards a welfare system that increases the incentives for lone mothers to move off welfare and into work. We analyze the consequences of a major Norwegian workfare reform of the generous welfare system for lone mothers. Our...

We analyze short and long-term effects of worker displacement. Our focus is on prime-age male workers displaced from Norwegian manufacturing plants. We find that displacement increases the probability of exiting the labor force by about 5 percentage points. This indicates that studies using data...
