GDP (output) growth in any country comes from either or both increases in inputs (primarily land, labour and capital) or the productivity of those inputs. As noted first in Lee Tsao Yuan’s 1982 Harvard PhD economics dissertation, and continuing to the present day, Singapore’s GDP growth has depended more on input than on productivity increases, as reflected in the high dependence on foreign labour.
This has had the unintended (but predictable) consequence of discouraging increased labour productivity.
Employers could increase output more readily and cheaply by recruiting foreign workers, particularly from lower-income countries, than by investing in capital-labour substitution and upgrading the skills of the domestic labour force. This was and is an entirely rational decision for profit-maximising private enterprises. Full story
