What is the primary implication of the 'Baumol-Tobin Model' of money demand?

A. Transaction demand for money exhibits economies of scale with respect to income and varies inversely with the interest rate.✓ Correct Answer
B. Money demand is entirely independent of interest rates and depends solely on the velocity of money.
C. Precautionary savings decrease when banking transaction costs rise.
D. Speculative demand for money drives asset market bubbles.

💡 Solution & Explanation

The Baumol-Tobin model demonstrates that the transaction demand for money exhibits economies of scale with respect to income and varies inversely with the prevailing market interest rate by treating cash holding like inventory management. Alternative models focus on speculative motives or precautionary cash buffers without applying inventory-theoretic cost minimization. This model treats trips to the bank as a transactional cost.
