Wage indexation,migration, and unemployment

This article sets up a two-goods model with wage indexation and migrants. A dual labor market is introduced where the domestic workers receive an indexed wage while migrants receive a market-determined wage. The traded sector may be assumed to be unionized while the non-traded goods sector is non-unionized giving rise to flexible wages. This provides an example of segmentation and wage indexation. The wage indexation creates unemployment in the traded sector and the segmentation allows this unemployment to persist. The main results obtained are: sector-specific migration of labor may raise domestic welfare, while with capital accumulation such migration necessarily raises the relative price of the non-traded goods, leading to structural adjustment.
