Money is a vital tool in our lives today. Without money, we will not be able to meet the needs and desires in life. Money is one object among many objects in the economic sense. Each object has a value, although the value of a single object with other objects is not the same. Society gives value to a thing, because it provides benefits to the community concerned. Only objects that have value to her request. So as for why people give value to something that matter, is because it was requested by the communities concerned, in other words because it gives benefits or to meet the specific needs of the communities concerned. The greater the benefits or needs can be met by something object, the higher the value of the object in question. Conversely the less the benefits provided by some things, the lower the value assigned by society to him.
Why does money have value? This question is not difficult to answer if it was accepted that the money that too is an object. Money as an object can not be separated from the description mentioned above. Clearly the money has value, because the public making a request to it. Furthermore, that money has value because it can meet the needs of the community in many ways. Indeed it is only as an intermediary tool alone, but because the money was to benefit as an intermediary tool then that money has value. Thus did the changes the value of money is closely linked to demand changes to it.
Whenever such a rising demand for money, then the value of money rises, the opposite if the demand for money is a little money and even then the value will decline. Rise and fall of demand for money we can see from the speed of the velocity of money. The faster the velocity of money means less demand for money, meaning money fled to the goods. Conversely, the slower velocity of money, the greater the demand for money, in other words the more people want to save some of his wealth in the form of money. In the circumstances the velocity of money very fast which means lower demand for money, value for money will fall. Furthermore, in a state of very slow turnover, which means rising demand for money, value for money will rise.
