In this blog post, we will discuss how the economy and financial system works? What drives the economy and how it rewards a certain type of people?

I am using Dollar as a currency for example in this blog, but it can be any currency like Rupee, Euro, Yen, Pound etc.

To understand the economy, let’s first understand “transactions”.

Transactions

Transactions are the root or the building block of the economy.

Every time we buy something, we create a transaction.

Each transaction consists of a buyer, who is giving money/credit, and a seller who is giving value/goods/services/financial assets. Spending drives the economy. Every dollar we spend, someone else earns; every dollar we earn, someone spends; easy-peasy.



It’s not that hard to understand that, almost everything in the economy is driven by transactions. Transaction to the economy is like biological cells to the human body.

Now, this buyer and seller chain can continue hundreds or thousands of times. Means a buyer can be a seller for someone else and a seller can be a buyer for someone else. Just like a businessman sells his/her products to others and buys other products from some other businessmen.



“Price” comes into play here in every transaction. Now let’s see what’s the “price” and how it’s get decided?


Price

Price is what we pay in the form of money/credit to get value/goods/services/financial assets. Now, the question comes, who decides the price?

Not any one person/organization gets to decide the price(unless it’s the monopoly) of a product/service, it’s all the game of supply and demand. We may think that companies decide the price of their product themselves, but over time it will come near to what the company’s competitor or the whole market is pricing their products.

For example, Tesla can’t price a particular type of car at $100k or $150k. Because then not many people will buy it because other car manufactures are selling similar cars at $35k to $50k price range.

Now, who decides that $35k to $50k price? Well, there are many factors at play but the major factor is the balance between supply and demand.

The price of a product/service is a subjective thing. According to sellers, it can be of price A. For buyers, it can be of price B. So, who’s correct? To decide the correct price, we need to go for the supply and demand balance point of that product/service.

Supply and Demand

Price is decided by how much something is wanted(i.e. demand) by the public vs. the supply of that thing.



High supply, low demand -> lower the price.
Low supply, high demand -> higher the price.

Whole stock market works on this very principle. For people who don’t have much idea about what stock market is, it’s a market for stocks/shares. Where shares of public companies are traded. A share is basically part of a company. When we buy a share of a company, we own certain percentage of that company. Market valuations / market caps of companies are calculated based on the price of the share in the stock markets.

In a stock market, an investor decides what should be the ideal price of a share of a company, and try to bid at that price to buy the share. At the same time, thousands or millions of other people are doing that same work. And whatever the majority decided price is for that moment, will be the price of that share at that moment.

Above process is happening at every second. That’s why the price of shares fluctuates every second. The slope of the share price graph shows the general sentiment of the public about that share.

We believe that this price has to be correct as the majority of the people believe that. Now, if that price is not correct and the majority is wrong, eventually, the bubble will burst and it will saturate to its actual price.

That’s why some people believe that a share is overvalued(i.e. bear markets) or undervalued(i.e. bull markets). They make bets according to their beliefs, and eventually whoever made correct predictions will make money in the future.

Brands like Supreme, Apple use the same supply-demand principle. They generate limited products compared to demand so, prices will be higher and so as their profit margins. Profit margins will be higher in low supply, high demand because, fundamental building cost of the product is not changing, just the price of selling is going up.

The development cost of a $999 priced iPhone is far less than that at around $500 to $600. They can charge that much money because of comparatively high demand of the product.

A lot of other things outside of the economy also use this “supply and demand” in one way or the other. Bidding markets also work on supply and demand principles.

Now, let’s understand “markets”.


Markets

A market consists of all the buyers and all the sellers making transactions for the same thing. For example, the car market, oil market, gold market, stock market, etc.

Economy consists of all of these markets and all of its transactions. All the markets connectively make the economy.

Now, these buyers and sellers can be anyone like,

  • People like you and me
  • Businesses/organizations
  • Banks
  • Governments

All of the above engage in transactions in the same way we just saw, exchanging money/credit with value/goods/services/financial assets.

The biggest player in the economy is the government. Which consists of two entities.

  1. Central government: Collects taxes and spends money at various places.
  2. Central bank: Controls the amount of money/credits in the economy.
    • It does this by controlling/managing two things.
      • Interest rates
      • Printing money/cash

Now, let’s understand loan/debt which bank issues and how interest rates & printing money affects the whole economy.


Loan/debt

We take loans/debts from lenders(like bank) by giving collateral and a promise to pay this money with interest in the future.

Now, when interest rates are high, there will be less borrowing because it becomes expensive. When rates are low, borrowing increases because it becomes cheaper.

Debt is an asset to the lender and a liability to the borrower. When we get money from the lenders, we spend that at various places like buying a house/car or building a business! So, when we spend more, someone else earns more. So, increased income allows increased borrowing, which allows increased spending; and since one person’s spending is another person’s income, this cycle continues.


Role of the central bank in an economy

So, if you can see this, the central bank kind of controls the economy! When the central bank increases interest rates, borrowing decreases, so the in-flow of money stops, spending decreases, and since one person’s spending is another person’s earning, earning decreases.

And as you might have guessed, when the central bank decreases interest rates, borrowing increases, so the in-flow of money starts, spending increases and so income increases of another person.



Banks can print money by giving some amount of gold. Here comes the “inflation” part. Inflation is nothing but a decrease in “value” or the “buying power” of money over time. Why does the value of money decrease?

Because if you see, when the central bank prints money, more amount of cash comes to market, but the amount of goods is almost the same!

Money/cash itself doesn’t contain any value. It’s just a piece of paper. We all have agreed that “this particular piece of paper contains a value of $1 or $10”. So, when new money/cash comes, the amount of value hasn’t increased in a similar amount.

Think of the above fact this way, if someone gives $1 million to every person on this earth, it loses its value. Because the amount of value/goods/services in the market is the same. So, the amount of bread which we used to buy for $1, now has a price of $5 or $20. Because the obsolete value of a dollar has been decreased.


What’s the difference between money and credit?

We can see credit as a promise to give money in the future. Like we do in loan/debt.

Credit is good when it’s issued for efficiently allocating resources that produces income and it’s bad when it’s issued for things that don’t produce income. Let’s take an example of a businessman or an entrepreneur who manages a company.

Economy rewards people who solve big problems

Almost all the famous businessmen and entrepreneurs initially had nothing compared to what they have today. They take a big amount of money from lenders(like banks, investors) & allocate that money to hire talented people and to build products/services. Ultimately they earn money by selling those products/services.

And after several years, with that money from profit, they repay that money with interest or in form of equity to lenders & invest remaining money in the company to hire more people and to build more and better products which will make them even more money. This cycle can continue forever.

So they started with nothing but a loan from the lenders and using their skills to build products/services, now they are earning more and more! This skill of attracting great people to work for them and building great products which solve people’s problems is making them more and more money!



Are you getting it? After several years, that skill is now translated into a good amount of money. At first, they had nothing but that skill and now they have lots of money too!

They took a risk to take big loans and to hire people to build a product in which they believed. There were chances of a complete failure. But they took calculated risks with their abilities and the economy rewarded them.

So, the economy rewards these kinds of people with a lot of money. Who can take big risks and solve big problems.

Maybe I am over-simplifying all this above, but that skill is not easy to learn. Hundreds of hurdles come in starting a company, in hiring talented people & to make them build products & in selling those products. But whoever does that, the economy surely rewards them.

Bigger the impact, bigger the reward.


I used to explore basics of economy and finance in the free time. So, all the things we discussed above are from various sources like YouTube and Wikipedia.

Hope now you have got at least some idea of how the economy works and how its reward system works!

Have a happy life!
