Takeaway

  • The economy is the sum of all transactions made in a society.
  • Someone’s spending is someone else’s income -> spending drives the economy.
  • The economy is governed by two cycles.
  • The first cycle is the short-term debt cycle. It lasts roughly eight years.
  • The long cycle is the long-term debt cycle. It lasts roughly 75 years.
  • These cycles govern the expansion and the recession of an economy.

What How the Economic Machine Works Talks About

How the Economic Machine Works is a video made by Ray Dalio. It explains how the economy works in a capitalist system. I learned that the economy is governed by two cycles: the long-term debt cycle and the short-term debt cycle. These cycles depend on the amount of credit in the economy and the interest rates.

Summary of How the Economic Machine Works, by Ray Dalio

The economy is the sum of all the transactions made.

A transaction is made when one provides a good or a service against money.

Transactions are made by different actors: people, businesses, banks, and the government.

People, businesses, banks, and the government.

The government is the biggest spender.

It is composed of two parts:

  1. The central bank, which controls the amount of money in the economy and the interest rate of the debt
  2. The central government, which collects taxes and spends them.

The government is made out of the central government and the central bank.

Money can be obtained from two sources: income (salary) and credit (borrowing money).

image 9
You get money through a salary, or by borrowing from the bank.

Your income depends on your productivity.

The more productive you are, the more money you will earn, the more money you will be able to borrow because lenders lend money to those that can pay it back.

You can’t borrow money without earning money. The borrower must have an income that will let him repay, or he must possess a collateral that will be sold to repay the debt in case he cannot.

If the collateral loses value or if the borrower’s salary decreases, the borrower becomes less creditworthy.

It’s important to understand that the way the economy is structured is that one man’s spending is another man’s income.

One man’s spending is another man’s income.

When you spend to buy a beer, you enable the bartender to make a living.

If you increase your productivity, your salary will increase, so you are more likely to spend more at the bar, and the bartender will earn more money, so he will spend more at the butchery and the butcher will earn more money, etc -> the economy grows and produces more.

However, it doesn’t matter much in the short term because productivity stays mostly flat and doesn’t really fluctuate (understand: people rarely increase their salary), so it doesn’t influence the economy much.

What influences it though, is credit.


The Short-Term Debt Cycle

Credit allows borrowers to get money now, and repay it later.

If you get money now, you will have more to spend.

When you spend more at the bar, the bartender increases his salary etc.

-> credit enables the economy to grow. Good!

But we don’t want too much of it.

When the money spent in the economy grows faster than the economy produces goods and services, prices rise and when prices rise, we call this inflation.

image 12

Eg: if the butcher is selling 10 steaks and there are 11 buyers, he will raise his prices.

The central bank does not like inflation.

So, it will prevent people from borrowing. To do so, it increases interest rates.

Since borrowing becomes more expensive, people borrow less.

If they borrow less, they spend less, so the economy contracts a little.

But it’s not all.

At some point, debt has to be repaid.

To do so, borrowers need to decrease the amount of money they spend.

No more drinks at the bar! So the bartender will earn less money, which will make the butcher earn less money, etc. The productivity of everyone decreases, which drives the income down.

image 13
When people spend less, everyone is earning less.

People buy less, so prices go down. This is called deflation.

Economic activity decreases and we have a recession.

If the recession becomes too severe (understand: people are not buying enough) and inflation disappears, the central bank will lower interest rates again to get people to borrow and consume again.

When interest rates decrease, borrowers have to repay less debt. Spending increases and the economy expands again.

As you can see, spending is constrained only by the capacity of lenders and borrowers to lend and borrow.

When credit is easily available, the economy expands. When credit isn’t easily available, the economy shrinks.

Notice how this cycle is controlled primarily by the central bank.

This short-term debt cycle lasts five to eight years and happens over and over.

The level of debt as the cycles go.

Notice that at the end of each cycle, we finish with more growth, but also with more debt.

Why?

Because people love spending (and many of them never repay).

They have an inclination to borrow and spend more instead of paying back debt, it’s human nature

Because of this, over long periods of time, debts rise faster than income, creating the long-term debt cycle.


The Long-Term Debt Cycle

Despite people becoming more indebted, lenders are always happy to extend credit. Why?

Because people only take into account short-term data: rising salaries and rising asset values (homes) help borrowers remain creditworthy.

Everyone is buying stuff (goods, services, assets) with borrowed money.

When people do that, prices reach heights they shouldn’t.

We call it a bubble.

As long as salaries continue to rise, debt can be repaid, so asset value increases.

People borrow ever bigger amounts of money to buy these assets as investments causing their prices to rise even higher.

But this obviously cannot continue forever. And it doesn’t.

At some point, the need to repay debt grows faster than salaries, forcing people to spend less.

Since one man’s spending is another man’s income, incomes decrease.

This makes people less creditworthy, causing borrowing to go down.

Debt repayments continue to rise, which makes spending drop even further and the cycle reverses.

Scrambling to repay debt, borrowers must sell assets.

The rush to sell assets floods the market while at the same time, spending falls.

The stock market collapses, the real estate market tanks and banks get into trouble because they lent too much money.

As asset prices drop, the value of the collateral borrowers can put up drops which makes borrowers even less creditworthy.

People feel poor, credit rapidly disappears.

Less spending -> less income -> less wealth -> less credit -> less borrowing, and so on.

It’s called a deleveraging.

image 16

In a deleveraging, people cut spending, incomes fall, credit disappears, asset prices drop, banks get squeezed, the stock market crashes, social tensions rise and the whole thing starts to feed on itself the other way.

This appears similar to a recession but the difference here is that interest rates can’t be lowered for two reasons: first, they are already low.

Second, borrowers don’t want any more debt anyway because the debt burden is too big and they won’t be able to repay.

The lenders realize they have to stop lending.

The economy has become not creditworthy.

So, what do you do about a deleveraging?

You must decrease the debt burden and there are four ways to do that:

1. Businesses and governments cut their spending

This is called austerity.

While we might expect the debt burden to decrease, the opposite happens.

Since everyone stops spending, everyone stops earning. Salaries fall faster than debt repayment, which makes the debt/income ratio worse.

When a borrower doesn’t repay the bank, people rush to the bank to withdraw money, banks get squeezed and people, businesses and banks default on their debts.

This severe economic contraction is a depression and a big part of a depression is people discovering much of what they’ve thought was their wealth is not there anymore.

Debt burden must therefore be lightened, which leads to the second point.

2. Debts are reduced through defaults and restructuring.

Many lenders don’t want their assets to disappear and agree to debt restructuring (changing the terms of the debt. Eg: paying less, paying more slowly, etc).

Even though debt disappears, debt restructuring causes income and asset values to disappear faster (because people are refunding their debt slower), so the debt burden continues to get worse.

All of this impacts the central government because lower incomes and less employment means the government collects fewer taxes, but it also means it needs to increase spending to care for the unemployed, to conduct daily business, and to create a stimulus plan.

Governments’ budget deficits explode. They need to find money somewhere, which leads to the third point.

3. Wealth redistribution

Since governments need more money, they increase taxes on the rich and redistribute the money to the less fortunate. These resent the rich for being rich, while the rich resent the poor for having to give them their money.

Social disorder can break out, tensions can arise in and between countries.

Since most of what people thought was money was actually credit, when credit disappears, people don’t have enough money and are desperate for it.

Since the interest rate is already low, and no one wants to borrow money, we need to go to the last point.

4. The central bank prints new money.

Unlike cut in spending, debt reduction and wealth redistribution, printing money is inflationary and stimulative.

Inevitably, the central bank prints new money out of thin air and uses it to buy financial assets and government bonds, which drives asset prices up and makes people (that own assets) more worthy of credit.

With that money, governments can pay for social security and launch their stimulus plan.

While this increases people’s income and lowers the economy’s total debt burden, it increases the country’s debt.

This is very risky (especially for countries that import a lot from abroad).

Policymakers must balance the four ways that debt burdens come down.

The deflationary ways (austerity) need to balance with the inflationary ways (printing) in order to maintain stability.

If balanced correctly, there can be a beautiful deleveraging where debts decline relative to income, real economic growth is positive and inflation isn’t a problem.

It is achieved by having the right balance which requires a certain mix of cuts of these four methods.

But will printing money not trigger inflation? It won’t if it offsets falling credit (understand: as long as you don’t print more than the level of debt).

Remember, spending is what matters. A dollar of spending from a salary is the same as a dollar of spending from a credit card.

By printing money, the central bank can make up for the disappearance of credit with an increase in the amount of money.

In order to turn things around, the central bank needs to not only pump up income growth but get the rate of income growth higher than the rate of interest on the accumulated debt (income needs to grow faster than debt grows).

You need to print enough money to get the rate of income growth above the rate of interest.

However, printing money could easily be abused because it’s so easy to do and people prefer it to the alternatives.

The key is to avoid printing too much money and causing unacceptably high inflation.

If policymakers achieve the right balance, a deleveraging isn’t so dramatic, growth is slow but debt burdens go down. That’s a beautiful deleveraging.

When incomes begin to rise, borrowers begin to appear more creditworthy, and when borrowers appear more creditworthy, lenders begin to lend money again.

Debt burdens finally begin to fall, people can spend more and the economy begins to grow again, leading to the reflation phase of the long-term debt cycle.

Deleveraging takes roughly a decade or more for debt burdens to fall and economic activity to get back to normal, hence the term “lost decade”.


Conclusion

So, in summary, there are three rules of thumb.

First, don’t have debt rise faster than income because your debt burdens will eventually crush you.

Second, don’t have income rise faster than productivity because you’ll eventually become uncompetitive (don’t pay people higher than the value they produce).

And third, do all that you can to raise your productivity because in the long run, that’s what matters most.
