Econ relationship between the multiplier and the MPC - The Student Room

That is Below Potential. Marginal Propensity to Save: Formula & Relationship to MPC. Multiplier in Economics: Definition, Effect & Formula. The terms "marginal propensity to save" and "marginal propensity to consume" are economic terms used to discuss how an entity deals with surplus income. The marginal propensity to consume (MPC) is equal to ΔC / ΔY, where ΔC is change in consumption, and ΔY is change in income. If consumption increases by.

So we have this kind of increase in spending that's going on.

Investment Multiplier - MPC & MPS (HINDI)

So he's going to spend, and the only person he can spend it with is the farmer. Somehow the economy seems to be picking up. He bought that much more food. I have a marginal propensity to consume of 0.

So it will be I'll write it as a decimal-- it'll be 0. So he's going to spend 0. I don't know, I could get a calculator to figure out what that is exactly. So let's say that I have 0. Or let's just write that-- 0. And I think you see where this is going. So it's going to be-- I'll write it here-- it's going to be 0.

Investment Multiplier and Income: Meaning and Relationship with MPC, MPS

So you're going to have 0. That's going to be 0. And I'll just calculated it. And it goes on and on and on. So the way to think about that, so the total-- and we could view it either way. Remember, you could view kind of the GDP. You could view that as the aggregate output.

You could view that as the aggregate income, aggregate expenditure. These are all views because really the economy is a very circular thing. One person's expenditure turns into another person's income. But we could say total output here, measured in our agreed upon currency, which is let's say dollars. So that was 0. And that gave us that 0. And then the last one we did, it would keep going on and on forever, theoretically, is you're going to have plus 0.

The Relationship Between Marginal Propensity to Consume & Marginal Propensity to Save |

And this would keep going on and on forever. We could then would be plus 0. Keep going on and on forever. And one of the fascinating things about mathematics, and maybe the next video, I'll reprove this.

I've proven this in multiple playlists, is that you can actually sum up because this value right over here is less than 1, this actually ends up being a finite sum.

Investment Multiplier and Income: Meaning and Relationship with MPC, MPS

You can actually take this infinite sum and get a finite number. And we are left with-- well if we factor of 1, there you get 1 plus 0. And in the next video, maybe I'll prove it, just for fun. It is a measure of change in national income caused by change in investment. Thus, it explains the relationship between increase in investment and the resultant increase in income. This equals increase in income divided by increase in investment. Investment multiplier indicates the multiplying effect of investment on income.

Remember, the value of multiplier determines the rate of growth in the economy A higher value of multiplier will attain a higher level of income and growth. This can be further clarified with the help of an example. Mind, multiplier works through consumption. Suppose, government invests Rs crore in establishment of a fertilizer factory. The first impact of this new investment will be that the income of employees engaged in this factory will go up by Rs crore. This is not the end of the story.

The producers of these goods will have an extra income of Rs 75 crore. The process of increase in income stops when change in income becomes equal to change in saving. The process of working of multiplier is further illustrated in the following table. The above table clearly shows that Initial increase in investment of Rs crore has resulted in an increase of additional income of Rs crore, i.
