Grain as a Unit of Account in the Marco-Julia Model
In the two-period model of intertemporal choice featuring Marco and Julia, grain is used as the unit of account. This means that all key economic quantities within the model—including assets, liabilities, net worth, consumption, and debt—are measured and expressed in terms of grain.

Evaluating a Proposed Economic Standard
In a small community that relies on bartering, a farmer trades chickens, a weaver trades cloth, and a potter trades clay pots. They find it difficult to agree on fair exchanges, such as how many pots are worth one chicken, or how much cloth is worth one pot. Which of the following economic problems would be most directly solved by establishing a common 'unit of account'?

The Value of a Common Measure
For an item to function effectively as a unit of account in an economy, it must also be the most commonly used medium for transactions.
An agricultural society uses 'baskets of ripe strawberries' as its official unit for pricing all goods, from tools to textiles. A farmer agrees in the spring to sell a plow for a price of 50 baskets, with payment due after the autumn harvest. Which of the following describes the most significant problem with using 'baskets of ripe strawberries' for this purpose?
An ancient society uses live cattle to price all other goods. A new tunic is priced at 1/10th of a cow, and a plot of land is priced at 20 cows. What is the primary difficulty this society would face by using live cattle as a standard for valuation?
In a barter economy, the following exchange rates are established: 1 bale of wool trades for 5 iron bars, and 1 iron bar trades for 10 loaves of bread. Based on these rates, what is the value of 1 bale of wool expressed in loaves of bread?
Evaluating Competing Valuation Standards
Learn After
In a simplified two-period economic model, Marco begins with an endowment of 100 bushels of grain. He lends 20 bushels to Julia, who agrees to repay the loan in the next period. Which statement accurately describes the financial standing of Marco and Julia immediately after this transaction, according to the model's measurement convention where grain is the standard for all valuation?
In a two-period economic model where all economic quantities are measured in terms of grain, consider the following situation: Marco owns a plow valued at 80 bushels of grain and has 20 bushels of grain in storage. He owes Julia 30 bushels of grain. A correct statement of Marco's net worth in this model would be '70 bushels of grain plus one plow'.
Calculating Net Worth with a Commodity Unit of Account
In a simplified economic model, all assets and liabilities on an individual's balance sheet are measured using grain as the single unit of account. Match each of the following situations to its correct representation within this model.

Calculating Net Worth in a Grain-Based Economy
In an economic model where all values are expressed in terms of grain, Julia has 50 bushels of grain in storage. She also owns a hoe valued at 15 bushels of grain and has a debt of 20 bushels of grain. Her total net worth, expressed in the model's unit of account, is ___ bushels of grain.
In a simplified economic model, all transactions and balances are measured in bushels of grain. In the first period, an individual borrows 100 bushels of grain, agreeing to repay 110 bushels in the second period. Between the first and second periods, a widespread crop failure significantly increases the effort required to produce one bushel of grain, effectively doubling its value relative to other goods like tools. Which statement best analyzes the financial implications of this loan from the perspective of the model's accounting system?
An economist is constructing a balance sheet for an individual in a simplified economic model where all value is measured in bushels of grain. Arrange the following steps in the correct logical sequence to determine the individual's net worth.
In a two-period economic model where all values are measured in bushels of grain, an individual starts with an income of 100 bushels. In the first period, they consume 60 bushels and use the remaining 40 bushels to acquire a productive asset (e.g., a plow). In the second period, this asset generates an output of 50 bushels, all of which is consumed. According to the model's accounting convention, this individual's total consumption over the two periods is 110 bushels of grain.
