"The market does not sleep. It dreams in price signals, and its dreams reshape the world."
The twin gravitational forces that shape every exchange, every negotiation, every silent act of choosing one thing over another. They are not laws written down; they are patterns that emerge from the collision of seven billion wills.
"each one an agent"
Every transaction is a conversation. Most of what is said is never heard.
In the space between cooperation and defection, civilizations rise and fall. The prisoner never knows whether the other prisoner has already confessed. The market never knows whether the other market has already priced in the catastrophe.
"Equilibrium is not a destination. It is the name we give to the place we have never been."
"the smallest possible preference"
The cost that no one agreed to pay. The benefit that no one intended to give. Every factory chimney is a vote cast on behalf of the atmosphere, counted by no ballot, recorded by no ledger -- until the ledger is the atmosphere itself.
Value is the ghost in the machine. You cannot weigh it, but it moves mountains.
The elegant proof that even the weakest participant has something to offer, and that isolation is always more expensive than exchange. Ricardo's insight, still radical after two centuries: trade is not zero-sum. The pie grows when the baker and the candlestick maker stop trying to do each other's work.
"purchasing power"
The interest rate is a price placed on patience. Those who cannot wait pay those who can.
When the consequences of failure are absorbed by someone else, the architecture of risk changes. Insurance creates the conditions for the very catastrophe it insures against. The safety net becomes the tightrope.
The road not taken is the true price of every road taken. Economics begins not with what you chose, but with what you gave up to choose it. Every yes contains an infinite lattice of nos, each one a phantom life unlived.
"Scarcity is the first word in the vocabulary of desire. Abundance is the last."
The hypothesis that agents, on average, get the future right. Not because they are wise, but because their errors cancel. The crowd is a calculating machine whose individual components do not know they are computing. Each mistake is a necessary input to collective accuracy.
Money is memory. Every coin is a compressed history of favors owed and debts forgiven.
Schumpeter's gale: the perennial storm of innovation that simultaneously creates and annihilates. The horse-drawn carriage gives way to the automobile, which gives way to the algorithm. Progress is a euphemism for the continuous extinction of the adequate by the superior.
The seller knows what the buyer does not. The borrower knows what the lender cannot see. In the gap between what is known and what is revealed, entire markets distort, premiums accumulate, and lemons drive out quality. Akerlof's insight: ignorance has a price, and someone always pays it.
Inflation is the slow confession that promises were made that could not be kept.
Non-rivalrous, non-excludable: the economist's description of a miracle. Clean air, national defense, the light from a lighthouse. Things that benefit all and can be withheld from none. The tragedy is that miracles are underfunded, because what belongs to everyone is maintained by no one.
"The invisible hand writes, and having writ, moves on. But the ink is made of consequence."
The first bite is ecstasy. The tenth is obligation. The hundredth is revulsion. Every input eventually yields less than the input before it. This is the fundamental melancholy of production: the universe charges increasing rent for decreasing wonder.
