## History of the Term

The concept of a multiplier has been around since the early days of economics. In the late 19th century, economist Alfred Marshall developed the concept of a multiplier to measure the effect of an increase or decrease in spending on the overall economy. Marshall’s multiplier was based on the idea that an increase in spending would lead to an increase in production, which would then lead to an increase in employment and wages, which would then lead to an increase in spending, and so on. This concept was later refined by economist John Maynard Keynes, who developed the concept of the multiplier effect.
