We show that a dynamic general equilibrium model with efficiency wages and endogenous capital accumulation in both the formal and (non-agricultural) informal sectors can explain the full range of confounding stylized facts associated with minimum wage laws in less developed countries.
I am actually surprised that minimum wage laws have any bite in countries where the informal sector is substantial and easy to access.
