The Baumol-Tobin model of money demand states that individuals hold money to minimize three types of costs: transaction costs, precautionary costs, and speculative costs. Transaction costs are the costs of making transactions, precautionary costs are the costs of holding too little money, and speculative costs are the costs of holding too much money.

The demand for money is directly proportional to the level of economic activity. This means that as the level of economic activity increases, the demand for money increases, and vice versa. This is because individuals and businesses need more money to facilitate transactions when the economy is growing.
