When Migrants Mobilize against Labor Exploitation: Evidence from the Italian Farmlands

Migrant labor exploitation is widespread in developed countries, which host growing populations of undocumented migrants. While denouncing by migrants is essential to prosecute exploitative employers, an undocumented community actively hiding from the state is unlikely to whistleblow. I consider an intervention providing migrant farmworkers in Italy information and incentives to report on their racketeers. I leverage the staggered rollout of the intervention to study its effects in a difference-in-differences framework. The intervention empowered migrants to whistleblow, increased the prosecution of criminal organizations responsible for racketeering migrants, and raised awareness among natives, who became more favorable toward immigration and parties supporting it. These findings highlight the conditions under which undocumented migrants can take political action for their socioeconomic advancement. Unlike other integration policies which have been shown to backlash, highlighting migrants’ vulnerability to exploitation might foster solidarity and more liberal immigration attitudes among natives.
