Evaluating a Proposed Economic Standard
An isolated island community relies on a barter system, where goods are traded directly. This creates a major problem: it is difficult to agree on fair exchange rates (e.g., how many fish equal one hammer? How many coconuts equal one fish?). To simplify trade, a proposal is made to price every good and service in terms of 'shiny shells.' For example, a fish might be priced at 2 shells, a loaf of bread at 1 shell, and a hammer at 15 shells. Critically evaluate this proposal. In your answer, identify the specific economic function the 'shiny shells' are intended to serve and assess two potential challenges or weaknesses of using a physical commodity like shells for this role over the long term.

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?
