This missing analysis would not be an issue if the existing research results on OECD countries applied equally to non-OECD countries, but they may be different due to a different context. Moreover, the economic and policy context in which these immigrants integrate into the labour market is different. As an example, the share of informal employment3 tends to be more elevated in lower than in higher income countries. Both of these factors likely contribute to impacts of immigration that differ between developed and developing countries.
