Thailand revealed that in 1987 56% of all tourism income leaked out of the economy
(Maurer, 1992). Leakage in fully import dependent countries such as Mauritius is reported
to reach 70% to 90% (Forschungsinstitut für Fremdenverkehr, 1982 cited in Maurer,
1992). While the data is clearly outdated, the claims of leakage rates in contemporary
literature are not less inconsistent.
