    • The economic multiplier effect is a concept that describes how an initial financial stimulus, particularly from government spending, can cause a more significant increase in national income. This is seen where, for example, a £1 billion boost results in a £1.7 billion increase in real GDP - signifying a multiplier value of 1.7. However, this can work inversely if government spending is reduced, potentially causing public sector job losses and a decrease in national income.

      The overall value of the economic multiplier is dependent on the amount of the new funds disposed of within the domestic economy, and is also impacted by the economy's spare capacity. If at full capacity, further fiscal inputs may merely result in inflation rather than economic expansion. Government tax cuts can also affect the multiplier effect as it directly influences consumer spending and investments.

      Additionally, the multiplier can be constrained by the crowding out effect - where increased government expenditure causes a reduction in private sector investments. However, from a Keynesian standpoint, during a recession this effect might be limited due to excessive unproductive savings in the private sector, which in turn could lead to a positive multiplier effect.
