Question

One of the important functions of money is to assist the consumers in maximisation of utility. Explain.

Answer 1

Money helps consumers maximise utility by providing a common unit in which prices are expressed (unit of account) and by serving as a widely accepted medium of exchange and store of value. Because goods and services have money prices, a rational consumer can compare the marginal utility per dollar spent across alternatives and adjust spending until the marginal utility divided by price is equalized across all goods, the condition for maximum total utility under a budget constraint. Money also lowers transaction and search costs, enables saving and borrowing (so consumption can be smoothed over time), and broadens the set of feasible exchanges and specialized goods available, all of which increase the consumer’s attainable utility. Textbook treatments summarize this role of money in facilitating the equalisation of marginal utilities via price signals and in enabling intertemporal choice and liquidity.
