“…Regarding (2), while transitions towards both secondary and tertiary sectors could induce inflows of young workers, the relative effectiveness between the two sectors in attracting labour depends on two competing forces. First, per Mao and Xu (2015) and Koeber and Wright (2001), the demand for young workers is relatively higher in the secondary sector than in the tertiary sector, suggesting more young-worker inflows if the secondary sector expands relative to the tertiary sector.
