Explain the geometric method of measuring price elasticity of demand.

Explanation

In geometric method we measure elasticity of demand at different points on demand curve. In this method elasticity of demand at any point on straight line demand curve is ratio of lower segment and upper segment of demand curve.

It is represented as:

Equation = Equation

State the law of demand and show it with the help of schedule.

Explanation

Law of demand states that all other factors being equal, as the price of a commodity increases, quantity demanded falls, likewise, as the price of a product falls, quantity demanded increases. There is a negative relationship between price and quantity demanded.

Example is given below:

Describe in Detail

In an economy, aggregate demand is less than aggregate supply. Is the economy in equilibrium? If not, explain the changes that will bring the economy in equilibrium.

Explanation

If aggregate demand (AD) is less than aggregate supply (AS) then economy is not in equilibrium because an economy is in equilibrium when AS = AD. When AD < AS, flow of goods and services in the economy exceed their demand. Some of the goods would remain unsold. So, unnecessary

Describe in Detail

From the following information about economy, calculate (I) its equilibrium level of national income and (ii) saving at equilibrium level of national income.

Consumption function: C = 200 + 0.9 Y

(Where C = consumption expenditure and Y = national income)

Investment expenditure: I = 3000.

Explanation

(i) its equilibrium level of national income

Y = C + I

Y = 200 + 0.9Y + 3000

Y-0.9Y = 3200

Y= Equation =32000

(ii) saving at equilibrium level of national income

Y = C + I

32000 = C + 3000

C = 32000 – 3000

C =
