Income elasticity of demand

Let's take an inferior good.

This will have begative income elasticity of demand.

Thus as income falls, demand rises.

Equally as income rises, demand falls.

OK....

If the price of the inferior good rises then real income falls.

Thus as per above, more is demanded.

So, the price of inferior godos rises and so does demand. So all retailers who sell cheap and tacky goods have to do is...raise the price!

Yeah?

Now let's deal with some of the comments:

If the price for inferior good rises the difference between inferior good and normal good will get less and because of that more people will switch to the normal good.

Yes but not everyone. I am referring to the people that do NOT switch!

In addition to that if the price of an inferior good rises it doesn't mean that the real income of all people becomes less. It will become less only for those who buy only that good.

I am referring to the people who buy the good. So, do you agree that to make more profit all the retailer has to do is raise the price?

I think the answer could be :

If the real income falls because of people spent more on inferior goods, therefore the inferior goods wont be demanded more because they bought inferior goods already.


But if the good is a consumer non-durable then there may be regular puchases

Rise in price of inferior goods will depend on how much demand response to the change in prise, it does not depend on the YED.

The rise in price depends on the reaction of demand?????

Not agree,about inferior goods,we're not considering about the price

So if price goes up - no problem?

Income and demand

Let's take a normal demand curve.

Income increases so the demand curve shifts to the right.

Now let's talk about elasticity.

One of the factors that affects elasticity is...income.

Therefore if income rises the SLOPE (gradient) of the demand curve changes...to the right.

Yeah?

Elastic supply



The above shows elastic supply.

If the curve was steeper but still going through the vertical axis would it still be elastic?

If the curve was flatter but going through the horizontal axis would the curve be inelastic?
