Upward Sloping Demand Curve

Veblen Goods

Price increase, then quantity demanded increase as well?? It is possible
It is argued that the attractiveness of some goods increases as their price increase.

Some people buy expensive things because they are expensive; the ownership of such goods puts them in a rather exclusive class.

For example: Expensive paintings, Vintage cars

When goods are purchased for ostentatious (show off) purposes and as their price rises so does their attractiveness because they provide a means of displaying superior wealth.

A fall in price might cause them to lose some of their appeal and the quantities demanded might fall because they will not be so effective as a means of displaying wealth.
