Q & A

What is the main purpose of money according to economists?

Money serves three main purposes: it acts as a medium of exchange, a store of value, and a unit of account.

Why is a barter system considered less efficient than using money?

The barter system is less efficient because it requires finding someone who has what you want and wants what you have, which takes time and energy. Money, on the other hand, is a universally accepted medium of exchange, making transactions quicker and easier.

How has the concept of money evolved over time?

Money has evolved from physical items like coins, cigarettes, and even mackerel in prisons, to digital forms like electronic deposits and cryptocurrencies like Bitcoin.

What is Bitcoin, and why do some people consider it money?

Bitcoin is a virtual currency that is not issued or regulated by any specific country. It is considered money by some economists because it is accepted as a medium of exchange by some people.

Why did the U.S. move off the gold standard, and what was the reaction?

The U.S. moved off the gold standard in the 1930s to have more flexibility in issuing money. Some people were concerned about not having tangible assets to back money, but many economists agree that money's value is based on confidence, not physical backing.

What are the two main groups involved in the financial system, and how do they interact?

The two main groups in the financial system are lenders (who want to save money for future use) and borrowers (who need money now and will repay it later). They interact through institutions like banks, bond markets, and stock markets.

How do banks function in the financial system?

Banks take deposits from lenders and loan that money to borrowers. The interest paid by borrowers is used to cover the bank's costs, with the remaining amount passed on to the depositors.

What is the difference between bonds and stocks?

Bonds are debt instruments where borrowers agree to pay back the loan with interest, while stocks are equity instruments where investors own a part of the company and may profit if the company does well.

Why do financial markets and instruments like stocks and bonds exist?

Financial markets allow borrowers to raise capital from many investors and spread the risk around. They also give lenders the ability to diversify their savings, reducing the risk of losing everything if a single borrower defaults.

How does the stock market differ from banks and bonds in terms of risk?

The stock market deals with equity, meaning that returns depend on the company's profitability, and shareholders may lose their investment if the company fails. In contrast, banks and bonds deal with debt, where repayment is typically guaranteed, making them less risky.
