My demand for money, is probably very mundane. I only wish to maintain money for what I need and the occasional purchase for goods and services that I want. I hold enough money in my pocket to purchase only small things here and there mostly in the form of essential goods like food. I keep enough money in my bank account in order to purchase bigger items every once in a while, and to cover emergencies when needed. My income is sporadic so maintaining a healthy demand for money can be hard. Money demand can be broken down into 3 different types.
