The multiplier is a basic concept of economics. If you come across some money and spend it, the person you spend it with then spends a proportion of it again, the recipient of which also spends some of it.

Plus, the commonly held assumption that if money starts circulating too quickly then it’ll assume less value. And what about those who want to accumulate wealth – do they stop the multiplier working?
