Can Labour Supply Explain the Rise in Unemployment and Inter-Group Wage Inequality in the OECD?

This paper investigates the consequences of labour supply changes in the OECD countries in the last decades. It is argued that changes in supply cannot be thought as homogenous: these changes involve more young and more adult female workers, that are complement with skilled men and substitute with low-wage groups (young, unskilled). Logically, these labour supply trends since the 50's increased competition between women, the young workers and the low skilled workers in some segments of the labour force.
