What happens to the demand of a good when consumer's income changes? Explain.
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.
A consumer consumes only two goods. Explain consumer's equilibrium with the help of utility analysis.
Market of a commodity is in equilibrium. Demand for the commodity 'increases'. Explain the chain of effects of this change till the market again reaches equilibrium. Use diagram.
