I added a brand new glossary merchandise this morning, on the multiplier effect. I add such entries each time I can or after I want them for one thing else I’m writing.
This entry says:
A multiplier impact is a measure of the quantity by which revenue is elevated or decreased on account of extra spending inside an financial system. If a multiplier impact is bigger than one then the extra spending produced a rise in revenue of larger than its personal quantity, and vice versa. The biggest multiplier results are often related to healthcare spending and capital funding, the place returns which can be a number of occasions the scale of the sum initially expended may end up. In distinction, defence spending has very low multiplier results. Some multiplier results e.g. these ensuing from spending on schooling are laborious to measure due to the prolonged time intervals concerned.
