Hello, this is Kori Insight 😊
What Is Money: From today, our Economic Education Series will focus on the daily economy,
designed so even beginners can understand easily.
Economics isn’t just about charts in news reports or heated debates among experts.
It’s present in the coffee you buy in the morning, the bus you take,
and the groceries you shop for after work.
At the center of all these activities is one thing: money.
According to the Bank of Korea, money is defined as…
Daily economy is closely tied to global trends, as shown in OECD reports.

1. What Is Money: The Definition of Money – More Than Paper and Numbers
In economics, money is a medium of exchange, a store of value, and a unit of account.
While it may look like cash, coins, or just numbers in your bank account,
money is in fact a symbol of trust shared by society.
If that trust collapses, money becomes nothing more than worthless paper.
2. A Brief History of Money – Evolving with Civilization
The story of money is closely tied to the history of human civilization:
- Barter System: Goods like grain, livestock, and salt were used for trade.
- Metal Coins: Gold, silver, and copper coins improved portability and value storage.
- Paper Money: Enabled large-scale distribution and long-distance trade.
- Electronic Payments: Cards and online transfers drastically increased transaction speed.
- Digital Assets: Cryptocurrencies allow trustless transactions without central authorities.
3. The Three Core Functions of Money
1) Medium of Exchange
It removes the need for a “double coincidence of wants” found in barter systems.
When you buy coffee today, you don’t bring coffee beans—you use cash or a card.
2) Store of Value
It allows you to use today’s earnings in the future.
However, inflation erodes purchasing power over time.
3) Unit of Account
It lets you compare the value of different goods using a single standard.
Example: “This smartphone is $1,200, that laptop is $1,500.”
4. Daily Economy and Money
Understanding the daily economy means tracking the flow of money.
From your morning coffee to your subway ride, every activity involves money.
The key is how you use it.
The same $10 can disappear instantly through impulse spending,
or it can grow through saving and investing.
5. The Value of Money and Trust in Nations
Money holds value because it is backed by the trust in the issuing country and its central bank.
A $10 bill issued by a central bank represents a social agreement:
“This piece of paper is worth ten dollars.”
If that trust collapses, money’s value can crash overnight.
(Example: Hyperinflation in Zimbabwe and Venezuela)
6. Money and Psychology – Why the Same Amount Feels Different
People don’t judge money purely by numbers—they see it through psychological value.
Example: Winning $300 in a lottery feels different from earning $300 at work.
Sales promotions and “limited editions” exploit this psychology,
often leading to unnecessary spending.
7. Practical Money Management Tips – Start Today
Knowledge of money is meaningless without good habits:
- Track Spending: Use a daily expense log to see patterns.
- 50:30:20 Rule: 50% needs, 30% wants, 20% savings/investment.
- Reduce Spending Triggers: Lower card limits and turn off shopping app alerts.
- Set Clear Goals: E.g., “House purchase” or “Travel fund” keeps you motivated.
8. The Future of Money – Change Is Already Here
Technology is rapidly transforming money:
- Cashless Societies: Sweden and Norway have less than 10% cash usage.
- CBDCs: Central banks are testing digital currencies.
- Blockchain Payments: Peer-to-peer transfers without banks.
- Metaverse Economy: Virtual goods trading in online worlds.
In the future, the key will not just be “how much money you earn”
but “what type of money you hold and how you manage it.”
9. Attitude Toward Money – The First Step to Financial Freedom
Money is not just a spending tool; it’s a resource that grants time and choices.
Used wisely, it improves quality of life; misused, it creates debt and stress.
If you want financial freedom, understand money’s essence
and build healthy habits in your daily economy.
