[quote="Schema"][quote="Question"][quote="Schema"] Sorry, I don't know what you mean in highlighting the words.[/quote9] Giffen Good一定是Inferior Good呢？! So, inferior good itself may not imply negative sloping[/quote9] 您的意思是指，Inferior Good的需求曲線不一定是向右下傾斜？[/quote9] Inferior Good=have negative income efeect but it can greater than the substritution effect or not greater than that greater than the substritution effect -->giffen good not greater than that-->not giffen good but still both are inferior good

[quote="Question"]Giffen good is inferior good. It is impossible to exist two inferior good in the model. Therefore, either good X or good Y must be normal good. If the good is normal good, it is impossible for such good is Giffen.[/quote6] If Good X is an inferior good, what will be the shape of ordinary demand curve for Good Y in the demand diagram? I think it can be upward or downward sloping. If it is upward sloping and we know that Good X is an inferior, can we say that both Good X and Y are inferior in the indifference curve map? :roll: Advise me if I am incorrect.

If it is upward sloping and we know that Good X is an inferior, can we say that both Good X and Y are inferior in the indifference curve map? :roll: Advise me if I am incorrect.[/quote9] what is "ordinary demand curve"? In the simplicity world, two goods cannot be both inferior good. I=Pxx+Pyy you can see when good x is inferior , y must be normal good or others and vice versa

Ordinary demand curve: the demand curve is ordinary :lol: Along this curve, money income is constant but the real income is not constant. When Px falls, the real income will be increased. (You can see from playing budget lines and IC)

Good X is inferior. How can you know? You have to isolate/compensate the income effect when Px falls/increases. The (ordinary) demand curve for it should be downward sloping. The extreme case is a straight line, the very extreme case is upward sloping (Giffen) Suppose Good X is inferior and the demand curve is downward sloping, what will be that for Good Y? I just think that when Py (relative to Px) increases, Qy can also increases. Therefore, the demand curve is upward sloping. What is wrong with my logic? :roll:
