Informal employment is a critical source of income for both internal migrants and non-migrants. This study uses the Rural–Urban Migration in Indonesia (RUMiI) project data for 2008 and 2009 to investigate the role of informal employment in earnings among internal migrants and non-migrants in Indonesia while considering the broader nature of informal employment and remuneration. Results show that when using a detailed measure of informality, income consequences of more intensive informal employment are severe, which had not been recognised in the literature. Some of the largest earnings reductions resulting from moving to more informal employment were experienced by non-migrants.

移民和非移民的工作形式和收入差异：来自印度尼西亚四个城市的证据

非正规就业是国内移民和非移民的重要收入来源。本研究使用 2008 年和 2009 年印度尼西亚农村-城市移民 (RUMiI) 项目数据来调查非正规就业在印度尼西亚国内移民和非移民收入中的作用，同时考虑到非正规就业和薪酬的更广泛性质。结果表明，当使用详细的非正规性衡量标准时，更密集的非正规就业对收入的影响是严重的，这在文献中没有得到承认。非移民经历了由于转向更多非正规就业而导致的一些最大的收入减少。
