If the autonomous consumption is given as 100 and the tendency of the people to increase consumption for an increase in income is only 20%, then derive the savings function.

Machines produced in an economy in a given year are a part of ................

The algebraic expression of aggregate demand for final goods can be written as:

If all people in the economy increase the proportion of income they save, then total savings in the economy will not increase; it will either decline or remain unchanged. This phenomenon is known as_____.

If there is an increase in investment by Rs100 in an economy, MPC = 0.9, choose the correct sequence with reference to the working of the investment multiplier.

(A) Producers increase their planned output further by (0.9)10, the income of the economy goes up by (0.9)10 and consumption demand increases further by (0.9)² 10.

(B) This process goes on, round after round.

(C) Income increases by 100, Consumption expenditure increases by 90 and therefore, aggregate demand goes up by 90.

(D) The total increment in the income will be 1000.

Choose the correct answer from the options given below:

__________ refers to that level of aggregate demand, which can be met by the corresponding supply in the economy.

Assume that in an economy increased consumption is equal to increased saving, how many times will the national income increase in such an economy with an increase in investment?
