What were the limitations of the barter system?
The barter system had several major limitations.
First, it required double coincidence of wants, meaning both parties had to want exactly what the other person was offering, which was difficult to find.
Second, there was no common standard measure of value, making it hard to compare the value of different goods and decide fair exchange proportions.
Third, the problem of divisibility arose because some goods like cattle could not be divided for smaller exchanges.
Fourth, there was the problem of portability, as carrying large or heavy goods for exchange was inconvenient.
Fifth, the problem of durability existed because many goods like wheat could rot or be destroyed over time, making them unsuitable for storing value.
These limitations made the barter system inefficient for everyday transactions.
Explanation
The chapter discusses these limitations through the farmer's story. The farmer with an ox faced the problem of double coincidence of wants—finding someone who needed an ox and could offer what he needed. The chapter states 'there is no common standard measure of value' when discussing exchange proportions. The divisibility problem is explained: 'you cannot exchange only a part of the ox for a sweater.' Portability is addressed: 'Taking the ox everywhere is a problem.' Durability is discussed: 'you cannot store the wheat for long; it would rot or get eaten by rats!'
Solution Steps
Double coincidence of wants - both parties must want exactly what the other offers
No common standard measure of value - difficult to compare values of different goods
Problem of divisibility - some goods cannot be divided for smaller exchanges
Problem of portability - large or heavy goods are inconvenient to transport
Problem of durability - perishable goods cannot store value over time
