my lecturer ask to me. why the total mpc and mps equal to 1??? i don’t know how to answer. do you have any idea about the answer??

Alright, first you have to know what is MPC and MPS.

In the simplest form, MPC is how much money you tends to spend for consumption (C).

For example, if your income (Y) is RM 100 and your MPC is 0.6, it means you tends to spend RM 60 or 60% of your income to consumption (C) like buying stuff or services.

MPS on the other hand is how much money you tends to make saving (S) from your income.

Based on example above, if you already spent RM 60 on consumption, obviously you make saving what’s left of your money right?

In mathematical form, it can be explained as follows,

Income (Y) = RM 100

Consumption (C) = 0.6 or RM 60 or 60% of income

Savings (S) = 0.4 or RM 40 or 40% of income

Thus,

MPC + MPS = 0.6 + 0.4 = 1 or 100%

Consumption (C) and Saving (S) is COMPLEMENT to each other,

it means if your C is 0.6, then your S is 0.4.

If your C is 0.75, then your S would be 0.25

If you add both C and S, it always made up as 1.

Hope this help :)

The suntikan bocoran is J-W. W stands dor withdrawal and J stands for?

In Keynesian economics, the symbol for Injection is ‘J’ which has no meaning unlike ‘W’ for withdrawal. The reason why they didn’t use ‘I’ to signifies injection is due to the fact that it has been used to denote for investment (I). Therefore, they substitute it with ‘J’ instead.

Dalam pendekatan suntikan-bocoran, untuk kes III bagi 3 sektor

100+50=-200+0.25Y+(Ta+tY)

100+50=-200+0.25Y+100+0.2Y

In your example, you missed the Ta=100

Am i right?

Dalam kes ini, cukai sekali gus (Ta=100) dan cukai berkadar (tY=0.2) diasingkan. Sebab itu ada dua contoh pengiraan; satu untuk Ta=100 dan satu lagi untuk tY=0.2

Tapi memang betul dalam dunia sebenar, (Ta) perlu dicampurkan dengan (tY) untuk membentuk (T) dan Y-T = Yd
