Readers Question How do economist use the theory of income elasticity to distinguish between different types of goods?
Income elasticity of demand measures the responsiveness of demand to a change in income.
Definition Inferior Good: An inferior good means an increase in income causes a fall in demand. It has a negative YED. An example, of an inferior good is Tesco value bread. When your income rises you buy less Tesco value bread and more high quality, organic bread.
Definition Normal Good. This means an increase in income causes an increase in demand. It has a positive YED. Note a normal good can be income elastic or income inelastic.
Definition Luxury Good. A luxury good means an increase in income causes a bigger % increase in demand. It means that the YED is greater than one. For example, high Definition TV’s would be luxury. When income rises, people spend a higher % of their income on the luxury good.
(Note: a luxury good is also a normal good, but a normal good isn’t necessarily a luxury good)

What are the definitions for Giffen,Bads and Complement Goods?
what are the effects elasticity on consumer goods and capital gods giving examples of the consumer and the capital goods?
where is others types
Speculative demand – potential buyers are interested not just in the satisfaction they may get from consuming the product, but also the potential rise in market price leading to a capital gain or profit
Giffen Goods – special type of inferior good may exist, which disobeys the “law of demand”. When the price of a Giffen Good decreases, the demand for that good decreases. This would have to be a good that is such a large proportion of a person or market’s consumption that the income effect of a price increase would produce, effectively, more demand. The observed demand curve would slope upward, indicating positive elasticity.
Complementary goods – are said to be in joint demand e.g. fish and chips, DVD players and DVDs, iron ore and steel. People generally purchase both goods together therefore a rise in the price of a complement to Good X should cause a fall in the demand for X and therefore good Y- A change in the demand for these goods will directly affect the demand for their complementary goods.
The extent to which a change in the price of one good leads to a change in the demand for a complement is determined by the cross-price elasticity of demand.
most people like me for instance…tend to find a problem on how other countries have a good economic growth while others stragle alot. i believed that the course of that is when a country exports more than it imports. Argumentatively, is well known fact that all the resources are scarce but what accually is scarce about them regardless of the nature because is never enough for humans. is it possible for all the countries to have the stable economic growth to monotor and innovate a common currency hance poverty reduced???????
