Why the 'bliss point' of circle indifferent curves always in the center of circles? Anyone can prove that with mathematic function?
Our observations in the real world tell us that a commodity can be good only up to a point called the point of satiation and becomes bad for a consumer if he is forced to increase his consumption beyond that point. There is a combination or bundle of the commodities which contains the optimal or most preferred quantities of the commodities for a consumer and any increase in the quantity of each of them beyond that best or optimal quantity will make the consumer worse off (that is, reduce his satisfaction), quantities of other commodities remaining the same. Too much of everything is bad. Reference: http://www.economicsdiscussion.net/notes/indifference-curves-between-goods-bads-and-neuters-with-curve-diagram/996
