‘Accommodation’ is chosen to show how the multiplier concept operates, but should be similarly imple-
mented for ‘food’, ‘transport’ and ‘Games tickets’. The three direct recipients of the injected money, after
allowing for leakages, subsequently spend this money in the same four ways, generating the indirect effect.
Leakages occur because some money could be spent outside the host economy. Moreover, some of the house-
hold income could leak out of the economy by the purchase of products from outside, or would not stimu-
