In the modern economy, the value of every good and service is denominated in terms of the unit of currency. Without money, the price of every good or service would have to be expressed in terms of every other good or service. The availability of money leads to a tremendous reduction in the amount of price-related information that is required to be processed.

Take the case of a 100-good economy. In the absence of money, we would require ¹⁰⁰C₂ or 4,950 prices.² However, if a currency were to be available, we would require only 100 prices, a saving of almost 98% in terms of the required amount of information. Think of the saving for a modern economy, which has billions of goods.
