​Abstract: A large portion of the labor force in many large factories in developing countries consists of internal migrants from rural areas, who may have little information about the industry upon beginning work. We examine whether workers' lack of information affects working conditions in the garment industry in Bangladesh. We use a retrospective panel of the wages and working conditions of 991 garment workers (matched to the factories they work in) collected in 2009. We find that internal migrants work in factories with worse conditions, but move towards factories with better conditions as they gain experience. These facts are consistent with a model in which migrants are poorly informed about working conditions upon beginning work but do learn as they gain experience in the industry.
