It is derived from Aggregate Demand and supply approach in the following way: Aggregate Demand in a two sector economy is defined as the sum of consumption expenditure(c) and investment expenditure (I) i.e. AD = C + I, where as Aggregate Supply is defined as the sum of consumption (c) and savings (s) i.e. AS = C + S.
What is saving and investment approach?
Saving represents withdrawal of some money from the income stream. On the other hand, investment represents injection of money into the income stream. Now, if intended investment is greater than intended saving, it means that more money has been put into the income stream than has been taken out of it.
What is aggregate demand and aggregate supply approach?
Key points. The aggregate demand/aggregate supply model is a model that shows what determines total supply or total demand for the economy and how total demand and total supply interact at the macroeconomic level. Aggregate supply is the total quantity of output firms will produce and sell—in other words, the real GDP.
How the equilibrium level of income is determined under saving and investment approach?
According to this approach, the equilibrium level of income is determined at a level, when planned saving (S) is equal to planned investment (I). In Fig 8.2, Investment curve (I) is parallel to the X-axis because of the autonomous character of investments. … At point ‘E’, ex-ante saving is equal to ex-ante investment.
Why saving is equal to investment?
