An econometric model is used to illustrate the strong connection of the immigrant workforce with production in the Thai economy, and therefore with levels of income. An empirical assessment of the impact of foreign-bom workers on income per capita cannot be made with certainty, but the high share of the employed in the foreign-bom population, together with the positive impact of foreign-bom workers on the Thai-bom paid employment rate, suggests this impact is positive. The labour market and broader economy would also benefit from the integration of foreign-bom workers in terms of the quality of work. Although foreign-bom workers are well-integrated in terms of access to employment, they remain concentrated in low-skill occupations.
