Through the business activities of private recruitment and employment agencies, it is clear that international migration is not simply the result of macro-structural forces, i.e. restructuring economies, governmental ethos, and the push-pull factors of wage differentials. It is not simply the outcome of micro-economic motivations either. For this category of migrant, as well as many migrant workers in Asia and elsewhere, it is also influenced by PREAs who serve as important shapers of global labour markets. Far from passive instruments merely responding to labour supply and demand, agencies actively search out new opportunities overseas, and establish linkages with local counterparts. To remain in business, they must keep the “pipelines” open and “inject a self-perpetuating dynamism into migration that continues longafter the original, usually economic, reasons for the flow may have been reduced” (Wee & Sim, 2004, p. 171).
