When is saving equal to actual investment?
Therefore, we observe that actual (ex-post) saving is always equal to actual (ex-post) investment. But planned or desired (ex-ante) saving is equal to planned or desired (ex-ante) investment only when national income is in equilibrium.
What is the relationship between intended saving and planned investment?
At a higher level of income, more is saved and therefore intended saving becomes equal to intended investment. On the other hand, when planned saving is greater than planned investment in a period, the level of income will fall. At a lower level of income, less will be saved and therefore planned saving will become equal to planned investment.
Why are Investments defined as saving and consumption?
Because people's totoal real income equal total actual goods and products produced that year, since people and the government only consume the Consumption and Government Purchases, the rest, the investment, is therefore defined as saving. I hope this can help a bit. Thanks for contributing an answer to Economics Stack Exchange!
How does the level of income affect the amount of saving?
As a result of this, level of income will rise and at higher levels of income more will be saved. It will be seen that with the rise in income to OY 2, saving rises and becomes equal to investment.
Why does savings equal investment in a closed economy?
Because people's totoal real income equal total actual goods and products produced that year, since people and the government only consume the Consumption and Government Purchases, the rest, the investment, is therefore defined as saving.
Why ex post saving is always equal to ex post investment?
Ex-post or actual investment is the sum total of planned investment and unplanned investment. It must be noted that ex-post saving and ex-post investment are equal at all levels of income. This equality between the two is brought by fluctuations in income.
How is saving related to investment?
When you save, you are usually able to pull that money out when you need it (or after a period of time). When you invest, you have the potential for better long-term gains or rewards, but also the potential for loss. You risk more in investing for a larger return, but your potential loss can be large as well.
Do savings and investment mean the same?
The biggest difference between saving and investing is the level of risk taken. Saving typically results in you earning a lower return but with virtually no risk. In contrast, investing allows you the opportunity to earn a higher return, but you take on the risk of loss in order to do so.
Why must planned savings of households be equal to planned investment of firms at the equilibrium level of income and output explain with the help of a diagram?
At the equilibrium point, planned savings by the households will always be equal to planned investment by the firms. This is because any deviation from the equilibrium level of income and output, will correct itself with the help of the Automatic Adjustment Mechanism.
What is the relationship between actual investment planned investment and saving in an economy?
In fact, it boils down to a simple formula: Actual investment is equal to planned investment plus unplanned changes in inventory. Actual and planned investments play a key role in the Keynesian economic theory, which focuses on total economic spending and how it affects both output and inflation.
WHO stated that savings and investment are equal but they are not always in equilibrium?
Keynes put forth two views with regard to the saving-investment equality.

What do you understand by ex-post saving and investment?
Ex-post is another word for actual returns and is Latin for "after the fact." The use of historical returns has customarily been the most well-known approach to forecast the probability of incurring a loss on investment on any given day. Ex-post is the opposite of ex-ante, which means "before the event."
What does it mean when S and I are equal?
It only means that S and I are and can be, equal at less than full employment (popularly called underemployment equilibrium). Classicals would call is a disequilibrium situation of the short period. But Keynes called it an equilibrium of the economy at a point of less than full employment.
What is the difference between saving schedule and investment schedule?
In this manner, saving schedule indicates various amounts of saving corresponding to different levels of national income and the investment schedule represents the various amounts of investment corresponding to different levels of national income. However, there is some unique level (equilibrium level) of national income at which savings calculated from the saving schedule are equal to investment calculated from the investment schedule. This is known as the functional equality of saving and investment and this is shown in the table and diagram as follows.
What is the difference between investment and saving?
This equality between saving and investment can be expressed in another way also: for example, Keynes defined savings as the excess of income over consumption, i.e., S Y C. Further, investment is the name given to expenditures other than the consumption expenditures, it is nothing but income minus consumption or I= Y- C. Hence S= I (because both are = Y – C).
What is Keynes's theory of saving and investment?
Keynes defined saving and investment in such a way that in his theory, saving always equals investment. This is called accounting equality. Accounting equality between saving and investment is also called logical identity. The logic behind this equality is as under.
What is income change?
Thus, income change is the mechanism through which the equality between saving and investment is established. Further, the novelty of Keynes’s approach to saving and investment equality lies in the belief that they can be equal at less than full employment.
How does Keynes explain the equality between saving and investment?
Keynes made it known clearly that the equality between saving and investment is brought about by the changes in the national income (and not by the rate of interest as stressed by the classicals). Let us see what happens when investment exceeds saving (by Rs. 20 crores) at a certain level of income (say Rs. 100 crores). This will increase national income through multiplier to such an extent that savings out of the increased income would be equal to the investment (or the excess of investment, i.e., Rs. 20 crores).
What was the most important print of the controversy between Keynes and Classics?
An important print of the controversy between Keynes and classics was the saving investment equality.
When any discrepancy between the plans to save and invest occurs a change in the level of income?
When any discrepancy between the plans to save and invest occurs a change in the level of income brings about a state of disequilibrium, and as income continues to change so do these plans get readjusted until a level of income is reached where planned saving and investment are once more equal to each other.
Why is the desired investment function horizontal?
The desired investment function is horizontal because in Keynes’ model all investment is autonomous, i.e., is assumed to be independent of national income. National income equilibrium occurs at point E where the desired saving function intersects the desired investment function.
Why do businesses hold inventories?
Some of the inventories business firms hold is planned (desired), because businesses require inventories to survive (i.e., because production and sales do not coincide). Some of it is unplanned (undesired) — business may be surprised by a brief recession that spoils their sales forecasts.
What is the equation for output and income?
As aggregate output and income are always equal and consumption is identical in both places, the rest of the equation must also be equal or Y = C + I and Q = GNP = C + S and if Y = Q, C + S = C + I or S = I.
How is the economic system in equilibrium?
Incomes are generated by production and the economic system is said to be in equilibrium when all the incomes earned are returned to the income flow through spending. Keynes’ income-expenditure analysis focuses on the relationship between aggregate expenditures and income.
How to understand the identity of firms?
The simplest way to understand this identity is to think of firms as producing a certain amount of goods, the value of which is just equal to the income received by all individuals in the economy (here the entire sales revenue of firms is paid out as income to factor-suppliers). That portion of national income which is not spend on consumption goods is saved. On the output side, firms either sell the goods they produce or put them into inventory, for future sale.

Why are ex post and ex post investments always equal?
For instance, when more investment is undertaken by the entrepreneurs how actual saving becomes equal to this larger investment and if the saving falls how investment will become equal to smaller savings.
When is planned investment equal to planned investment?
At a lower level of income, less will be saved and therefore planned saving will become equal to planned investment. We thus see that planned or ex-ante saving and planned or ex-ante investment are brought to equality through changes in the level of income. When ex-ante saving and ex-ante investment are equal, level of income is in equilibrium i.e., it has no tendency to rise or fall.
