[Summary]
Stocks, wages, interest rates, foreign exchange, and real estate prices all move our society through prices.
So who decides those prices?
Most economic news reports the outcome: stocks rose, wages increased, the yen weakened, or interest rates moved. What we should really look at is the power behind those prices.
"New Price Formation Theory" is a series that reads modern capitalism through the struggle among markets, companies, states, central banks, regulators, and platforms over the rules that form prices.
This series is not simply an explanation of prices.
It is about the rules of price formation, or the struggle for control.
This article is a general discussion of economic and market structures. It does not recommend any financial product, stock, real estate, loan, insurance, work style, or tax decision. For actual decisions, check the latest rules, contract terms, interest rates, tax treatment, and your own risk tolerance.
The Question Behind The Series
Prices look like neutral numbers.
But the distribution of wealth changes dramatically depending on who controls the rules that decide those prices.
Those who control the rules behind stock prices affect corporate financing power. Those who control wage-setting rules affect workers' lives. Those who control interest rates affect mortgages, corporate investment, and government bond markets.
A price is not just an exchange ratio.
It is also the control over capital, labor, credit, information, and regulation expressed as a number.
This series asks one question:
Who decides that price?And then it asks one level deeper:
Who controls the rules that decide that price?Part 1: Prices Decided By Markets
Part 1 covers capital markets, labor markets, financial markets, and foreign exchange markets.
It is easy to say that markets decide prices. In reality, market participants, institutions, liquidity, regulation, information asymmetry, and expectations all interact.
| Theme | Core question |
|---|---|
| Capital markets | Who decides stock prices? |
| Labor markets | Who decides wages and staffing fees? |
| Financial markets | Who decides interest rates? |
| Foreign exchange markets | Who decides the value of the yen? |
Capital Markets
Stock prices are not determined only by a company's past profits.
The market looks at how much future market share the company can capture, what kind of network it can control, how much value it can create above its cost of capital, and how much pricing power it can maintain.
The capital markets chapter reads capital markets as a mechanism that prices the future.
Labor Markets
Wages and staffing fees are also prices.
It is tempting to say that wages rise when labor is scarce. In practice, corporate competition, staffing fees, margins, regulation, minimum wages, and bargaining power are all intertwined.
The labor markets chapter uses the Japan Fair Trade Commission's inspection of major staffing agencies as an entry point into labor-market price formation.
Financial Markets
Interest is the price of money.
Short-term rates are strongly influenced by central bank policy, while long-term rates incorporate market expectations, inflation outlooks, government bond supply and demand, and overseas rates.
The financial markets chapter reads interest rates as a joint product created by central banks and markets.
Foreign Exchange Markets
Foreign exchange is the price at which a state's credibility is evaluated across borders.
Interest-rate differentials, capital flows, trade balances, monetary policy, and government intervention all matter. The price of the yen is not decided by markets alone, nor by the state alone.
The foreign exchange chapter reads the yen's value as a price formed by mutual constraint between state sovereignty and the economic rationality of global capital.
Part 2: Price Formation In The New World
Part 2 covers the price of data, AI, and knowledge.
This is where the problem becomes harder.
Who owns data? When AI can generate text, images, code, and analysis at scale, how are knowledge and creative work priced? When platforms control distribution, where does the pricing power over individual labor and creative output move?
| Theme | Core question |
|---|---|
| Data markets | Who decides the price of data? |
| AI markets | Does the price of knowledge disappear? |
| Overall thesis | Price is power |
Data Markets
Data is not an asset with a visible standalone market price like oil or gold.
In exchange for free services such as search, maps, social media, and video, users provide browsing histories, search terms, location data, and purchase histories. But the price formation process for that data is extremely hard to see.
The data markets chapter examines a structure in which the price is not attached to data itself, but to the probability of predicting attention.
In the AI era, it may not be work itself that disappears first.
The first thing to change may be the price of work.
Why Ask About Price Formation Now?
Inflation, wage growth, yen weakness, rising interest rates, AI investment, real estate prices, electricity bills, and medical costs.
The economic news of the 2020s looks like a story about prices.
But if we only follow the surface numbers, we miss the point.
Why did stock prices rise? Why are wages not rising? Who benefits when interest rates move, and who is squeezed? Why can companies profit from a weaker yen while households feel poorer?
The answer lies not in prices themselves, but in the rules that decide them.
This series is not for chasing price news.
It is for reading the power structure that decides prices.
Conclusion: To Look At Prices Is To Look At Society
Prices are numbers floating on the surface of society.
But underneath them are corporate bargaining power, state regulation, central bank policy, worker position, consumer burden, investor expectations, and platform control.
To look at prices is also to look at society.
Stocks, wages, interest rates, foreign exchange, and real estate.
Behind every price are someone's intent, someone's bargaining power, and someone's institutional design.
"New Price Formation Theory" is a series that peels back those hard-to-see structures one by one.
