You are already familiar with the term “trade”

Trade is a tertiary economic activity involving the voluntary exchange of goods and services between two parties. One party sells, and the other purchases, making trade mutually beneficial. In some traditional societies, barter—the direct exchange of goods without money—is still practiced. For example, a potter needing plumbing services must find a plumber who needs pots to exchange goods directly. This system, however, has limitations such as the need for a double coincidence of wants. Trade occurs at two levels: national and international. International trade involves the exchange of goods and services across national boundaries. Countries engage in international trade to obtain commodities they cannot produce themselves or can buy more cheaply elsewhere. The barter system was the earliest form of trade in primitive societies, but it was replaced by money to overcome difficulties such as lack of a common measure of value and divisibility. Before the advent of paper and coin currency, rare objects with intrinsic value like flintstones, obsidian, cowrie shells, tiger's paws, whale's teeth, animal skins, cattle, rice, peppercorns, salt, small tools, copper, silver, and gold served as money. For instance, the word 'salary' comes from the Latin word 'Salarium,' meaning payment by salt, reflecting salt's high value in ancient times when it was rare and expensive.

Frequently asked questions

What is the primary difference between national trade and international trade?

Trade conducted within a country versus trade across national boundaries

Which of the following best describes the barter system?

Direct exchange of goods and services without using money

Why was salt historically used as a mode of payment, giving rise to the word 'salary'?

Salt was rare and expensive in ancient times because it could only be produced from rock salt, making it valuable as a medium of exchange. The Latin word 'Salarium' means payment by salt, which is the origin of the word 'salary'.

Explain the main difficulty of the barter system that led to the introduction of money.

The barter system required a double coincidence of wants, meaning both parties had to want what the other offered at the same time. This limitation made trade difficult and inefficient, leading to the introduction of money as a common medium of exchange to facilitate trade.
