From Barter to Money | Class 7 Social Science Notes

Before money was invented, people exchanged goods and services directly through a system called barter. In this system, people traded items they had for items they needed without using any common medium like money. For example, if someone had extra erasers but needed pencils, and another person had extra pencils but needed erasers, they could exchange these goods directly.

Money came into existence to solve the problems faced in the barter system. The barter system required a double coincidence of wants, which was difficult to find. It was also hard to determine the value of goods relative to each other, and some goods were not easily divisible or portable. Money provided a common standard of value, was divisible, portable, and widely accepted, making trade easier and more efficient.

Money has transformed from barter goods like cowrie shells, salt, and cattle to metal coins and then to paper notes. Over time, money has also taken the form of electronic money used in mobile phones and computers. Different societies used different items as money, such as Rai stones in Micronesia, copper knives in Central America, and feather coils in the Solomon Islands. This evolution reflects the need for money to be portable, divisible, and widely accepted.

The difficulties encountered include: 1) Finding someone who wants the exact item you have to offer (double coincidence of wants). 2) Difficulty in determining the fair value or proportion in which goods should be exchanged (lack of common standard measure of value). 3) Problems with divisibility, as some goods cannot be divided (e.g., an ox). 4) Portability issues, as some goods are difficult to carry around (e.g., bags of wheat). 5) Storage problems for goods that are not durable or easy to st
