Determination of Equilibrium Income

According to the Keynesian theory of employment, the state of underemployment is obtained only when the economy is in equilibrium. 

In an economy, $C = 300 + 0.8Y$ and $I = 500$ (where C = Consumption, Y = Income, I = Investment). Calculate the following: (a) Equilibrium level of income; (b) Consumption expenditure at equilibrium level of income.

If in an economy, C = $500 + 0.9Y$ and I = Rs. $1,000$ crores, where C = Consumption Expenditure, Y = National Income, I = Investment. Calculate the Equilibrium Level of Income.

If in an economy: (a) Consumption function is given by C = $100 + 0.75Y$, and (b) Autonomous Investment is Rs. $150$ crores. Estimate Equilibrium level of Income.

If in an economy: (a) Consumption function is given by C = $100 + 0.75Y$, and (b) Autonomous Investment is Rs. $150$ crores. Estimate Consumption and Savings at the Equilibrium Level of Income.

Given the following information, identify whether the economy is in equilibrium or not:

In an economy, C = $200 + 0.5Y$ is the consumption function where C is the consumption expenditure and Y is the national income. Investment expenditure is Rs. $400$ crores. Is the economy in equilibrium at an income level Rs. $1,500$ crores? Justify your answer.

In an economy the autonomous investment is Rs. $100$ and the consumption is C = $80 + 0.4Y.$ Is the economy in equilibrium at an income level Rs. $400$? Justify your answer.

Calculate the equilibrium level of income in the economy, if C = $500 + 0.9Y$; and Investment Expenditure = Rs. $3,000$.

From the following data calculate the equilibrium level of national income:

An economy is in equilibrium. Calculate national income from the following:

From the following data about an economy, calculate its equilibrium level of income:

Calculate equilibrium national income from the following:

Answer the following questions based on the data given below:

Planned level of investment = Rs $200$ crores $C = 100 + 0.8Y$ 

(a) Determine the Equilibrium Level of Income.

(b) Calculate the saving and consumption expenditure at equilibrium level of income.

The consumption function is given as $C = 75 + 0.75Y$ and autonomous investment is Rs $100$ crore. Derive the saving function and calculate the level of income at which saving is equal to investment.

In an economy, $C = 300 + 0.8Y$ and $I = 500$ (where C = Consumption, Y = Income, I = Investment). Calculate the following: (a) Equilibrium level of income; (b) Consumption expenditure at equilibrium level of income.

In an economy $S = -50 + 0.5Y$ is the saving function (where S = saving and Y = national income) and investment expenditure is Rs $7,000$. Calculate: (i) Equilibrium level of national income. (ii) Consumption expenditure at equilibrium level of national income.

In an economy, the consumption function is $C = 600 + 0.9Y$, where C is consumption expenditure and Y is income. Calculate the equilibrium level of income and consumption expenditure, when investment expenditure is $500$.

The consumption function of an economy is given as: $C = 200 + 0.75Y$, If planned investments are Rs $500$ crores, calculate equilibrium level of national income.

The consumption function is expressed as: $C = 100 + 0.25Y$ (where C = consumption expenditure and Y = National Income). Calculate saving if consumption expenditure at equilibrium level of national income is Rs $500$ crores.
