Use the Baumol–Tobin model to explain how each of the following events would change the demand for money:
War breaks out, making it dangerous and more costly to travel.
The rate of inflation increases and is expected to continue to increase.
The Baumol–Tobin real demand for money can be expressed as -
where -
1. P is price.
2. Y is real output
3. Md is nominal demand for money
4. is transaction cost
5. i is interest rate (or opportunity cost of holding money)
a. If war breaks out, then they will want to hold more cash and hence transaction cost ( ) will increase as people will find it dangerous and more costly to travel.
b. If rate of inflation increases then people will need more money to buy the same quantity of good. Hence the demand for money will increase as Price level (P) will increase.
