## What is equilibrium investment equilibrium saving?

The classicists held that if saving and investment are equal at a time, they will be soon brought into equilibrium by **automatic changes in the rate of interest**. Given the rate of investment, if saving increases, then the rate of interest will fall. With the decline in the rate of interest, investment demand will rise.

## How is equilibrium level of income determine by saving and investment?

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.

## What changes will take place in an economy if investment and savings are not equal?

(ii) When planned saving is not equal to planned investment, i.e., when planned spending is not equal to planned output, then output will tend to adjust up or down until the two are equal again. **Adjustment Mechanism** (when planned saving is not equal to planned investment).

## How do you calculate equilibrium level of savings?

Most simply, the formula for the equilibrium level of income is when **aggregate supply (AS) is equal to aggregate demand (AD), where AS = AD**. Adding a little complexity, the formula becomes Y = C + I + G, where Y is aggregate income, C is consumption, I is investment expenditure, and G is government expenditure.

## How will a 100% increase in government spending affect equilibrium output?

A change of, for example, $100 in government expenditures will have an **effect of more than $100 on** the equilibrium level of real GDP. … This is called the multiplier effect: An initial increase in spending, cycles repeatedly through the economy and has a larger impact than the initial dollar amount spent.
