Dual Economic Roles of Grain in the Simplified Marco-Julia Model
In the simplified Marco-Julia model, which features only one good and no formal money, grain takes on two fundamental economic roles. It functions as a unit of account, providing a standard measure for value, and also as a store of value, allowing wealth to be held over time. These are two of the three primary functions typically performed by money in a modern economy.

The Role of a Financial Intermediary
In a simple economic model, an individual with an initial endowment of a good can lend directly to an individual with no endowment. If a bank is introduced to act as an intermediary, where the first individual deposits the good and the bank then lends it to the second individual, how does the nature of the financial claim held by the original lender change?

Economic Functions of a Commodity
In an economic model where grain is the only good and there is no formal currency, one person agrees to lend 100 units of grain to another.

Dual Functions of a Commodity in a Simple Economy
In a simplified economic model where grain is the only good and there is no formal currency, grain can serve different economic functions. Match each scenario with the primary economic function of grain it illustrates.
Evaluating a Commodity's Economic Functions
In a simplified economic model where the only good is grain and no formal currency exists, the fact that individuals can hold onto their grain to consume or lend out at a later date means that grain is fulfilling all three primary functions of money.
In a simplified economic model where grain is the only good and no formal currency exists, an individual sets aside 20 units of grain from their harvest to consume during the winter. In this context, the grain is primarily fulfilling the role of a ____.
In a simplified economic model where grain is the only good and there is no formal currency, a loan transaction occurs. Arrange the following events in the logical order they would happen, from the initial agreement to the final settlement.
In an economy where grain is the only good and there is no currency, a farmer lends 50 bushels of grain to a neighbor, with the agreement that 55 bushels will be repaid next year. The farmer then stores an additional 100 bushels in a secure silo for her own future use. Which statement best analyzes the economic roles of grain in this scenario?
In a simple economy where apples are the only good and there is no currency, a farmer lends 100 apples to a baker, with the agreement that 110 apples will be repaid in one year. During that year, a severe blight drastically reduces the apple harvest, making each remaining apple much more valuable. Which statement provides the best analysis of the economic functions of apples in this situation?
