[> [> [> Subject: Re: ECON (MICRO) Author: Oldyof7A [ Edit | View ] Date Posted: 22:04:26 10/03/04 Sun That the D curve be downward sloping is an assertion of economics. Economists have confidence in the assertion because, if anyone succeeds in rejecting the assertion he will deserve the Nobel prize in Economics. The prize is such a good that many scientists are dreaming for it. That means, many economists are trying to reject the assertion but no one has succeded so far. Thus, the assertion has the status of a Law in social science.

[> Subject: Re: ECON (MICRO) Author: @@ [ Edit | View ] Date Posted: 00:41:25 10/08/04 Fri The Law of Demand states that the higher the price of a good, the lower its quantity demanded other things being constant(ceteris paribus) Giffen good exists when an inferior good which has its income effect overweights its subsitution effect Substitution effect is always negative, as a lower relative price always leads to an increase in the quantity demanded. For inferior good, the quantity demanded will decrease when consumer's real income increases. When this negative income effect is greater than the substituion effect, the quantity demanded will increase with price, the demand curve for giffen good is upward sloping. This doesn't follow the Law of Demand. The existence of a giffen good is a logical possibility, if giffen good is observed in the real world. The Law of demand will be refuted. Therefore, the law of demand is asserted rather than derived.
