Regional informal institutions, local governance and internal migration in Vietnam
研究越南国内迁移受区域非正式制度与地方治理质量的影响，发现不同制度区域吸引不同类型的迁移，且跨制度迁移损害收入，而向治理更好地区迁移则提升收入。
Internal migration is an institutionalized process; it is affected not only by economic factors but also by institutional forces. This study thus employs institutional theory to investigate the importance of regional informal institutions and local governance quality on types of migration, as well as their impacts on migrants' earnings. Examining a set of national internal migration data in Vietnam, we find that pure socialist regions (the north) attract in-migration for job-seeking purposes, while pre-capitalist regions (the south) attract in-migration for business opportunity-seeking purposes. More importantly, migration across regions with dissimilar informal institutions yields adverse effects on migrants' earnings. Finally, migration from regions with a lower governance quality to regions with a higher governance quality improves migrants' earnings.
