Supposing you had to come up with a definition of economics short enough to fit in a dictionary...what would it be? For myself, I would not start out by pretending its a science...certainly not merely because it involves numbers. Nor would I call it an art...although it does include an element of aesthetics. One can easily see how much of the value in things people want is devoted to appearance. Unless you want to live here: Please Register or Log in to view the hidden image! Its perfectly functional...just not particularly charming. So, I would simply define economics as a STUDY...what the Greek philosophers called a 'logos'. The study of exchanges quantified through the medium of money. Thats the most concise sentence I can manage at the moment.
