Compared to barter, money increases efficiency primarily by resolving which issue?

• A. The double coincidence of wants
• B. The need for a central broker
• C. The requirement of bartering only goods for services
• D. The inability to price goods

Answer: (A)

The main idea here is that money boosts efficiency by removing the need for a double coincidence of wants. In a barter system, a trade only happens if each party simultaneously wants what the other has, which drastically limits and slows exchanges. Money serves as a widely accepted medium of exchange, so you can sell your item for money and then use that money to buy whatever you want from anyone else. This separation—selling for money and buying with money— Enables many more trades and makes markets work more smoothly. Other statements miss the central point. Money isn’t primarily about needing a central broker, and barter allows many kinds of exchanges beyond goods-for-services. While money does provide a convenient unit of account and can simplify pricing, the core efficiency gain comes from eliminating the need to find someone who exactly wants your particular item at the same time you want theirs.
