For example, if an increase in German government spending by €100, with no change in tax rates, causes German GDP to increase by €150, then the spending multiplier is 1.5. Other types of fiscal multipliers can also be calculated, like multipliers that describe the effects of changing taxes (such as lump-sum taxes or proportional taxes).
Chapter 10 introduces the famous 'multiplier' through an example: if the marginal propensity to consume is 90%, then 'the multiplier k is 10; and the total employment caused by (e.g.) increased public works will be ten times the employment caused by the public works themselves' (pp. 116f). Formally Keynes writes the multiplier as k=1/S'(Y).
The multiplier–accelerator model can be stated for a closed economy as follows: [3] First, the market-clearing level of economic activity is defined as that at which production exactly matches the total of government spending intentions, households' consumption intentions and firms' investing intentions.
For example, an individual's reduction in spending reduces the incomes of others and their ability to spend. [1] In a broader global context, research has shown how monetary policy decisions, especially by major economies like the US, can create ripple effects impacting economies worldwide, emphasizing the interconnectedness of today's global ...
This example shows us how the multiplier is lessened by the existence of an automatic stabilizer and thus helping to lessen the fluctuations in real GDP as a result of changes in expenditure. Not only does this example work with changes in T, it would also work by changing the MPI while holding MPC and T constant as well.
The tableau économique is credited as the "first precise formulation" of interdependent systems in economics and the origin of the theory of the multiplier in economics. [5] An analogous table is used in the theory of money creation under fractional-reserve banking by relending of deposits, leading to the money multiplier.
The Regional Input–Output Modeling System (RIMS II) is a regional economic model developed and maintained by the US Bureau of Economic Analysis (BEA).. Regional input–output multipliers such as the RIMS II multipliers allow estimates of how a one-time or sustained increase in economic activity in a particular region will impact other industries located in the region—i.e., estimating ...
For example, (a) labor, hours worked (b) productivity, how effective firms use such capital or labor, (c) investment, amount of capital saved to help future endeavors, and (d) capital stock, value of machines, buildings and other equipment that help firms produce their goods.
