Example of Grain as a Medium of Exchange in the Extended Marco-Julia Model
In the extended Marco-Julia model, the function of grain as commodity money is demonstrated by its use as a medium of exchange. For example, rather than consuming their grain directly, characters like Marco can use it to buy other products. He could exchange five units of grain at a supermarket for groceries of the same value.

Example of Grain as a Medium of Exchange in the Extended Marco-Julia Model
An economist initially models a simple economy with only two individuals who trade their single, respective products directly with each other. To better understand the development of a system of exchange, the economist then expands the model to include a large marketplace with many different individuals producing and selling a wide variety of goods. What is the primary economic problem that this expansion from a two-good to a multi-good economy is intended to demonstrate?
An economist wants to construct a model to demonstrate the fundamental reasons why a common medium of exchange (money) becomes essential in an economy. Which of the following scenarios provides the most effective foundation for this model?

Selecting an Appropriate Economic Model
Expanding an economic model from a simple two-person, two-good framework to a multi-good 'supermarket' scenario is primarily done to demonstrate how efficiently direct trade (barter) can operate in a more complex economy.
Evaluating Economic Models for the Study of Money
An economist develops two models to study the origins of a medium of exchange. Model A depicts a simple economy with only two individuals who produce and trade a single good each (e.g., one grows wheat, the other raises chickens). Model B depicts a complex economy with many specialized producers offering hundreds of different goods and services. What is the most significant challenge to direct trade that emerges when moving from Model A to Model B?
Transactional Challenges in a Growing Economy
An economist is building a model to illustrate the emergence of a medium of exchange. Arrange the following steps in the logical sequence an economist would use to construct this model and demonstrate the problem it solves.

Functions of Goods in an Economy
In a small, isolated community, a weaver produces high-quality blankets but needs vegetables from a farmer. The farmer, however, already has enough blankets and will not trade vegetables for them. The weaver knows that the community's blacksmith highly values blankets and always needs them. The weaver trades a blanket to the blacksmith for several standardized iron ingots. The weaver then takes the iron ingots to the farmer, who readily accepts them in exchange for vegetables, knowing they can use the ingots later to buy other goods. In this economic system, which item is serving as the medium of exchange?
Consequences of a Supply Shock on Commodity Money
In an economy where grain is widely used to purchase various goods, a shoemaker who accepts grain in payment for shoes does so primarily because they intend to use the grain for their own family's consumption.
Evaluating Commodity Money
In an economy where a specific good, such as grain, is used for both personal use and for trade, match each scenario with the primary function the grain is serving.

Impact of Scarcity on a Commodity Medium of Exchange
A farmer has harvested 100 bushels of wheat. They need 50 bushels for their family's food for the year. They also want to acquire a new plow from the blacksmith, which costs the equivalent of 50 bushels of wheat. Which of the following actions best demonstrates the farmer using wheat as a medium of exchange?
