Short Answer

Expert verified

The existence of money simplifies the buying and selling process by eliminating the need for a double coincidence of wants, providing a standardized measure of value, allowing easy storage and transfer of value, and facilitating credit transactions. This streamlines transactions and makes trading goods and services in an economy more efficient compared to the barter system.

Step by step solution

1. Understanding Barter System

Before the invention of money, people used the barter system for trading goods and services. In a barter system, people would exchange items of equal value directly without any medium of exchange, such as money.

2. Problems with Barter System

The barter system had several limitations, including the need for a "double coincidence of wants" (both parties must want what the other is offering), difficulty in measuring the relative value of items, and the lack of a common unit of account and storage of value (goods would deteriorate over time).

3. Introduction of Money

Money was introduced as a medium of exchange, unit of account, and store of value. When people started using money as a medium of exchange, the buying and selling process became less complicated, eliminating the need for a barter system.

4. Simplifying Buying and Selling with Money

The existence of money simplifies the buying and selling process in several ways: a. Eliminates the need for a double coincidence of wants: Money provides a common medium of exchange, and you can buy goods or services without finding someone who has a direct need for what you have to offer. b. Provides a standardized measure of value: Money acts as a unit of account, and it is easy to compare the value of different items. c. Allows easy storage and transfer of value: Unlike perishable goods, money can easily be stored and transferred from person to person. d. Facilitates credit transactions: The use of money also makes it easier to lend, borrow, and repay debts.

5. Conclusion

In conclusion, the existence of money simplifies the process of buying and selling by eliminating the need for a double coincidence of wants, providing a standardized measure of value, allowing easy storage and transfer of value, and facilitating credit transactions. Money acts as an efficient medium of exchange, streamlining transactions and making it easier to trade goods and services in an economy.
