Money vs Goods

The Core Relationship

Imagine an economy with 100 units of money and 100 units of goods. Each unit of goods costs 1 unit of money. Now double the money to 200 while keeping goods at 100. Each unit of goods now costs 2 units of money. The goods didn't change. The money did.

But it works both ways. If you keep money constant and double the goods, each unit of goods costs only 0.50. Prices fall — not because of a recession, but because of abundance. Try it yourself.

Why This Matters

In a productive economy with stable money, prices should naturally trend downward over time as technology, efficiency, and innovation create more goods and services. The fact that prices persistently rise tells you something important: the money supply is growing faster than real output.

This is a simplification — velocity, credit, and sectoral dynamics add complexity. But the core relationship holds across centuries of data: sustained, broad price increases require monetary expansion relative to real output.

From Tokens to Dollars

The demo above uses tokens and apples, but the same dynamic plays out in the real economy with dollars and everything you buy. Between January 2020 and January 2022, the U.S. M2 money supply grew from roughly $15.4 trillion to $21.6 trillion — a 40% increase in just two years. Real GDP, the actual goods and services produced, grew roughly 3% over the same period. More money chasing modestly more stuff. Prices responded exactly as the model predicts.

This wasn't unique. Every major episode of sustained price increases in recorded history — from third-century Rome to 1920s Germany to 1970s America to 2000s Zimbabwe — traces back to the same mechanism. The money supply expanded far beyond what the real economy could absorb.

Why It's Not Always Instant

If the relationship were this mechanical in real time, predicting inflation would be trivial. It isn't, because several factors create lag and noise between monetary expansion and price changes.

Velocity — money doesn't always circulate at the same speed. During recessions or crises, people and businesses hold onto cash rather than spending it. New money can sit in bank reserves or savings accounts for months before it enters the real economy. This is why the massive monetary expansion of 2008–2014 didn't immediately produce consumer price inflation — much of it stayed in the financial system.

Where the money goes first — new money doesn't enter the economy evenly. It flows through specific channels: bank lending, government spending, asset purchases. The first recipients benefit from pre-inflation prices. By the time the money reaches wages, grocery stores, and rent checks, prices have already adjusted. This is the Cantillon Effect, and it's one of the least understood dynamics in economics.

Measurement — the CPI captures a specific basket of consumer goods. It doesn't fully reflect housing costs, asset prices, education, or healthcare — categories where price increases have been most dramatic. The money shows up in prices. It just doesn't always show up where the official index is looking.

The Bottom Line

The tokens-and-apples model isn't a metaphor. It's the actual mechanism operating beneath every price tag in the economy. The complexity of modern banking, global trade, and financial markets adds noise and delay — but it doesn't change the fundamental arithmetic. When the supply of money grows faster than the supply of things money can buy, each unit of money buys less.

The next question is: where does all this new money actually come from? The answer is more surprising than most people expect.
