Interesting new paper by Dinkelman and Ranchhod on the Journal of Development Economics (ungated version here).  Here’s the abstract:

What happens when a previously uncovered labor market is regulated? We exploit the introduction of a minimum wage in South Africa and variation in the intensity of this law to identify increases in wages and no statistically significant effects on employment on the intensive or extensive margins for domestic workers. These large, partial responses to the law are somewhat surprising, given the lack of monitoring and enforcement in this informal sector. We interpret these changes as evidence that strong external sanctions are not necessary for new labor legislation to have a significant impact on informal sectors of developing countries, at least in the short-run.
