Q. What is Demand for money?

Demand for money

As for any type of goods, there is a demand for money and a supply of money. Remember that demand for an arbitrary good is the amount an individual wants to purchase (and pay for with money) under numerous conditions. Demand for an arbitrary good is always associated to money. Though the demand for money can't relate to money itself - how much money we want to 'buy' with money becomes a pretty useless definition. 

Instead, we define demand for money as the amount out of your wealth that you wish to hold as money. We use the symbol M_D to demand for money. In IS-LM model, there is just one alternative to money and that's bonds. 

If your total wealth is 1.000 euro and you want to keep 100 euro in cash or in an account connected to a credit or debit card and the rest in government bonds then your demand for money is indeed 100 euro. It's the amount which you want to have easily accessible for immediate payments. It is noteworthy that having a low demand for money doesn't mean that you don't want money. In its place, it means that you prefer to hold most of your wealth in other sorts of assets.
