Question

Discuss the working of the adjustment mechanism in the following situation:

Ex Ante Investments are lesser than Ex Ante Savings. 

Explain the adjustment mechanism in case ex-ante savings are greater than ex-ante investments.

Discuss the working of the adjustment mechanism in the following situation:

If Ex-Ante Investments are less than Ex-Ante Savings.

Answer 1

When Ex Ante Investments are less than Ex Ante Savings.
The situation when S exceeds I, i.e., when withdrawal from the income is greater than injections into the circular flow of income, then it implies that total consumption expenditure is less than what is required to purchase the available supply of goods and services. In other words, we can understand this as high saving implies low consumption, which means that the required output is less than the planned output. Thus, a portion of the supply remains unsold, which leads to unplanned inventory accumulation. In response to this situation, to clear this unsold stock, the producers plan a cut in production in the next period. Therefore, reduce the employment of labourers. The reduced employment leads to a fall in aggregate income in the economy, consequently, lesser aggregate savings. The savings will continue to fall until it becomes equal to the investment. At the point where saving and investment are equal, equilibrium is achieved.

This process of athe djustment mechanism is explained below graphically.

In the figure, S and I represent the Saving and Investment curves. Let us suppose that the equilibrium is facing a situation where saving (TY’) exceeds investment (KY’). Consequently, the aggregate consumption expenditure is lower than what is required to buy all the goods and services. Therefore, there exists unplanned inventory accumulation of unsold stock equal to TK (i.e. TY’ – KY’), and the producers respond by reducing production and employment. Due to reduced employment, the income of the factors of production (of the people) falls. Subsequently, the savings will fall due to reduced income. Hence, the savings will continue to fall until savings equate investment at point E. The economy achieves equilibrium at point E, with saving equal to investment and the OY level of national income (or output).

Answer 2

Ex-ante savings, or planned savings, exceed ex-ante investments, or planned investments, indicating that families want to save more than businesses want to invest. As a result, the economy is in a state of low demand.

1. Excess Supply: The whole supply (C + S) exceeds the total demand (C + I). Producers discover that their inventory levels are rising above what they would want.
2. Reduced Production: Producers lower production to get rid of excess inventory.
3. Decreased Income: Savings decline along with income. Until projected savings and planned investments are in balance, the process remains ongoing.
4. Equilibrium Restoration: At a lower income level, where expected savings and planned investments are equal, the equilibrium is restored.
