Question 21: Take some simple object, a shoe or a rubber ball, and differentiate between its properties, its utility, and its use value.

[52] Stxian: Let's take a simple good as an example: a pair of shoes. The properties of a pair of shoes itself has none.

Hans: Yes it does. Its properties are porosity and elasticity, weight, the abrasion and friction properties of its soles, mechanism for fasten it to the foot (shoe laces).

Imagine a little green man from Mars who has never seen a human being but finds an old shoe somewhere in the ice near the south pole and writes a report about its properties.

[52] Stxian: It use value depends on the shoe's utility. There are three usefulness in which humans use. First one is that we can wear it on our foot, so it's easier for us to walk; the second is that sometimes, shoes are made to distinguish one's social statue, sexuality and personality. The last human use of a pair of shoes is we can use the shoes to throw it at someone we “dislike” or angry to. These three usefulness all determine the utility function of the shoes, because each represented a different degree of satisfaction. The use value of the shoe is depended on how each individual human beings'objective and purposeto acquire a pair of shoes. The most expensive use value in terms of money is to use shoe as a source of showing off, to distinguish you as a upper class in the society. The most common use value of the shoe is that people buy them to wear them so they can walk better outside of home.

Hans: Good.
