Components of the Modern Money Supply

The Origin of Modern Money

In a small, isolated community, several items are used in trade. Freshly caught fish are often exchanged for other foods but must be consumed within a day. Unique, handcrafted sculptures are highly valued and held as family treasures, but rarely traded. Iron nails, which are durable and uniform, are frequently traded, but their value fluctuates wildly depending on the arrival of supply ships. Finally, seashells of a specific type are consistently accepted by everyone in exchange for any good or service, and all items in the local market have their prices listed in number of shells. Which of these items best fulfills the primary roles of money in this community?

In an ancient society, large, immovable, and uniquely carved stone wheels are considered the primary measure of wealth. Families are judged by the number and quality of wheels they own, and these wheels retain their value across generations. However, for daily purchases like food and tools, people trade in smaller, more common items like shells. Based on this scenario, why do the stone wheels fail to function fully as money for this society?

Consider an economy where the real wage is at a level where workers' wage demands are consistent with firms' price-setting decisions, resulting in no upward or downward pressure on inflation.
