by means of the amounts sent by emigrants and the corresponding foreign currency
income. This factor had an important influence on the Spanish take-off of
the 1960s, thanks to two million (more than 10% of the work force) emigrants
(Tamames, 1986). Foreign currency allowed the acquisition of industrial equipment.
In Mexico, emigration today comprises 1.7% of the GDP and in Morocco is
the main source of foreign currency. On the other hand, emigration also means –
because of the emigrants that return temporarily or permanently home – a flow
of new ideas of all sorts that might help in the economic, social and political
transformation.
