why mpc + mps = 1 ?
Since MPC+MPS=1 Then MPS=1-0.5=0.5 Tax Multiplier= -(MPC/MPS)=-0.5/0.5= -1
MPC is the Marginal Propensity to Consume. You can find the MPC by taking the change in consumption divided by the change in disposable income. Likewise, MPS is the Marginal Propensity to Save. You can find the MPS by taking the change in savings divided by the change in disposable income. It is useful to know when you want to find out what the multiplier is. Multiplier = 1/MPS or 1/(1-MPC)
MPC=0.75 As 500/125=4 Therefore MPS=0.25, as 1/0.25= 4 MPC= 1-MPS Therefore 1-0.25 =0.75
1/1-MPC or 1/MPS+MPT+MPM

Taxation Multiplier = - (MPC) / (1 - MPS) Where, MPC = marginal propensity to consume, and MPS = marginal propensity to save.
The formula for this simple tax multiplier. (m[tax]), is: m[tax] = - MPC x 1 ---- MPS = - MPC ---- MPS Where MPC is the marginal propensity to consume and MPS is the marginal propensity to save. This formula is almost identical to that for the simple expenditures multiplier. The only difference is the inclusion of the negative marginal propensity to consume (- MPC). If, for example, the MPC is 0.75 (and the MPS is 0.25), then an autonomous $1 trillion change in taxes results in an opposite change in aggregate production of $3 trillion.
MPC=0.75 As 500/125=4 Therefore MPS=0.25, as 1/0.25= 4 MPC= 1-MPS Therefore 1-0.25 =0.75

According to Keynes, if MPS = 1 then, in a closed system, MPC must be 0. The only alternative is to borrow - which defeats the purpose of saving all the marginal increase in income! Therefore, it is possible but most unlikely.
The marginal propensity to consume (MPC) is an economic concept to show the increase in personal consumer spending or consumption that occurs with an increase in disposable income. Here is the formula: MPC = change in consumption/change in disposable income A change in disposable income results in the new income either being spent or saved. This is the Marginal Propensity to Consume (MPC) or the Marginal Propensity to Save (MPS). MPC + MPS = 1
Multilplier is the ratio by which a given increase in investment brings about an increase in the national income. The extent of the increase in income ranges from 1 to infinity depending on the mariginal propensity to consume (MPC) and marginal propensity to save (MPS). Multiplier is symbolised by the aphabet "K" and its value is calculated as under:1 1K = ------------------------- = -----------------------1-MPC MPSIf MPC =1, K = infinity and if MPC = 0, K = 1 and in between there are numerous ratios, depending on the data in a question.Multiplier can also be defined as the reciprocal of marginal propensity to save because K = 1/MPS
Relationship if: MPC decreases, K (Multiplier) will be weaker MPC increases, K will be stronger MPC = o(zero), K = 1 MPC = 1, K= infinity in real life: K = more than 1 & less than infinity MPC = less than 1 & more than 0 Assumptions: K works better in a closed economy (no foreign trade) K works better in an economy which has not reached full employment level
