Vertical Integration: Owning the Step That Decides the Product
Buying from specialists is usually cheaper, and sometimes it means you cannot be better than anyone else. The right boundary moves as an industry matures — and rarely gets revisited.

Metcalfe's Law: Why Second Place Is So Much Worse Than Second
Ten times the users gives roughly a hundred times the possible connections. The exact formula overstates things — the underlying point about compounding leads does not.
Creative Destruction: The Damage Is the Mechanism
New methods can only grow by taking resources from old ones. The productivity gain and the displacement are not cause and side effect — they are the same event seen from two sides.
Competitive Exclusion: Two Things Cannot Want Exactly the Same Thing
Species with identical needs cannot coexist — a small consistent advantage compounds until one is gone. Which means anything living side by side must differ, and finding how is informative.
Zero-Sum and Positive-Sum: Two Very Different Games
Two children share one cake and one child's gain is the other's loss. Two neighbours swap mangoes for apples and both end up better off, with no new fruit. Telling these apart changes what you should do.
Commoditize Your Complement: Why Companies Give Things Away
Profitable companies spend years building things and then hand them out for free. There's a clean piece of economics behind it — and it tells you where you sit in someone else's plan.
Two-Sided Markets: The Shopping Centre With No Shops
Retailers won't join without shoppers; shoppers won't come without retailers. Both are right to wait — and how you break that deadlock defines every marketplace business ever built.
Economic Moats: Hard Work Is Not an Advantage
Two shops on one street do everything right; one closes. Quality and effort are what you need to compete at all — a moat is what stops a rival matching you even when they genuinely try.
Natural Selection: The Algorithm That Needs No Designer
Your eye has a blind spot no engineer would design. That flaw reveals the process that built it — a process that governs markets and ideas as strictly as it governs retinas.
Aggregation Theory: How Free Distribution Rewrote the Rules of Monopoly
A newspaper needed presses and trucks to control its market. An aggregator controls a bigger one with neither — because the internet moved the choke point from distribution to attention.
Network Effects: The Only Moat That Deepens While You Sleep
A lone fax machine was a paperweight. The machines never improved — the network did. That distinction separates genuine network effects from the many businesses that merely have a lot of customers.
The Innovator's Dilemma: How Doing Everything Right Ends Companies
Incumbents rarely lose because they were careless. They lose because listening to their best customers, protecting margins, and ceding the unprofitable low end are each individually correct — and collectively fatal.
The Red Queen Hypothesis: Running Hard to Stay Exactly Where You Are
Species that have survived for ten million years go extinct at about the same rate as new ones. That surprising fact explains why your improvements so often buy you nothing.
The Prisoner's Dilemma: When Two Rational People Both Lose
Betraying your partner is the correct choice no matter what they do. So both of you betray, and both of you serve five years instead of one. No error was made — and that is exactly the problem.
Nash Equilibrium: Why Everyone Stays Somewhere Nobody Likes
Two petrol stations cut prices until neither can move without losing. Nobody wanted the result, everyone behaved sensibly, and it held anyway — because stable and good are different properties.
In a Fast-Moving Conflict, the Winner Is Whoever Decides Faster — Not Whoever Decides Best
A slightly worse decision made quickly and adjusted often beats a perfect decision made too slowly to matter.
Big Tech: The Companies That Own the Starting Point
None of these companies owns most of what it sells. They own the place people begin — and that turned out to be the most valuable position in the economy.
Startups: Most Advice Comes From the People It Worked For
Persistence and bold bets describe the founders who succeeded — and just as many who didn't, and aren't being interviewed. A structural view of these companies is more useful than the folklore.
Business Models: What Would You Give Up to Earn More?
How the money arrives is the least interesting part. Every model has a lever for growing revenue and a cost attached to pulling it — and where that cost falls predicts behaviour under pressure.
Competition: Better at What, Exactly?
Two firms selling something interchangeable can only compete on price, and every improvement gets matched. The useful question is not how hard to compete but what you are competing on.
Antitrust: The Test Was Built for Prices That Never Rose
A century of competition law detects monopoly by watching consumer prices. When the service is free, the test finds nothing — and the power sits somewhere it was never designed to look.
