Value

Value has to do with the comparison of goods based on the classification and categorisation of characteristics that lead to a preference or choice. Goods can be compared based on price (currency value scale), uniqueness (cultural value scale), or looks (aesthetic value scale). 

As such, value is socially constructed, it is generated dynamically, it can be various, and variable, it depends on social conventions, and is influenced by information available to make the comparison.
