Does economic development in the source countries diminish migration pressures? This does not
automatically follow from any assertion that differences in earnings opportunities contribute significantly
to migration pressures. Tighter labor markets do not always accompany more rapid economic growth,
though they are certainly positively correlated. Some have argued the opposite, that economic
development among the poorer nations may actually exacerbate migration pressures. Yet, if there is a
lower arm to a migration hump then any such hump seems to turn at very low incomes, and the evidence
to support such a turning point seems tenuous in recent migration patterns. Where a migration regime
permits movement of relatively unskilled workers, economic development at origin apparently does serve
to diminish migration pressures. This is particularly, and possibly only, true when the development
strategy chosen in the sending nations serves to tighten labor markets at home
