Short Answer TypeDefine an indifference curve. Explain why an indifference curve is downward sloping from left to right.
When price of good is Rs 7 per unit a consumer buys 12 units. When price falls to Rs6 per unit he spends Rs 72 on the good. Calculate price elasticity of demand by using the percentage method. Comment on the likely shape of demand curve based on this measure of elasticity.
What does the Law of variable Proportions show? State the behaviour of total product according to this law.
Explain how changes in prices of other products influence the supply of a given product.
Explain how the following influence demand for a good:
Rise in income of the consumer.
Rise in income of the consumer:
Income of consumer is an important determinant of demand. The rise and fall of the demand for a good as per the rise in income of consumers depends upon the nature of good. Normal goods have a positive income elasticity of demand, so as consumers' income rises, more will be the demand. A rise in the income of the consumer will increase the demand for the good. In the case of Luxury goods and services, demand rises more than proportionate to a change in income. Inferior goods have a negative income elasticity of demand meaning that demand falls as income rises.
