Primary members (86)¶

Primes whose canonical origin is Economics & Finance.

Access Friction — An entry-asymmetric cost paid only by those crossing a membership boundary, shaping who is present rather than who is qualified.
Adverse Selection — Hidden pre-contractual types make participation under uniform terms systematically more attractive to the types worst for the uninformed side, degrading or unraveling the pool.
Agency Problem — Misaligned incentives.
Anti-Coordination Game — Each player's payoff is higher when its action differs from the others', so the best-response correspondence is anti-aligned, pure equilibria are asymmetric, and the hard problem becomes who plays which role — the formal dual of a coordination game.
Antifragility — A system that gains capability from stressors and volatility, not merely withstands them.
Arbitrage (Finance) — Exploits mismatches.
Arbitrage (Generalized) — Exploiting a discrepancy in price, value, or perception across a boundary that friction keeps from equilibrating, extracting the spread until it closes.
Auction Theory — Auction behavior analysis.
Black Swan (High-Impact, Low-Probability Events) — High-impact unexpected events.
Common Knowledge — A fact is common knowledge when everyone knows it, everyone knows that everyone knows it, and so on without limit — the infinite-tower condition that enables coordination.
Comparative Advantage — Efficient specialization.
Cooperation — Agents bear individual costs to produce a shared benefit.
Cost–Benefit Analysis — Evaluate decisions.
Creative Destruction — Replacement through innovation.
Deadweight Loss — Lost surplus.

Diseconomies of Scale — Rising per-unit cost once scale grows past a point.
Distributional Effects — An aggregate outcome conceals systematically heterogeneous, unit-level changes.
Division of Labor — Partition a joint activity into specialized sub-tasks assigned to distinct performers whose outputs are then re-integrated.
Economies of Scale — Cost reduction with scale.
Economies Of Scope — Cost savings from producing varied outputs together.
Efficient Market Hypothesis (EMH) — Prices reflect info.
Evolutionarily Stable Strategy — A population strategy is stable if, once dominant, no rare mutant can invade — equilibrium defined by what survives perturbation, not by ex-ante agreement.
Expected Utility — Ranking risky options by their probability-weighted utility.
Externality — Spillover effects.
First Mover Advantage — When a contest rewards early arrival, the same move yields a different return depending on when in the sequence it is taken.
Free Riding — The systematic under-provision that results when individuals can enjoy a non-excludable shared good without contributing proportionately to producing it.
Gains from Trade — Mutual benefit exchange.
Goodhart's Law — When a proxy is placed under binding optimization pressure, its correlation with the construct it was meant to indicate collapses.
Incentive Compatibility — Align incentives.
Indifference Curves — Equal satisfaction sets.
Information Asymmetry — Parties to an interaction hold unequal private knowledge.
Keynesian Beauty Contest — The rational choice is not what you most prefer, nor what you think others prefer, but what you think others believe others will choose.
Liquidity — Ease of conversion.
Lock-In — Forward-looking cost of switching exceeds the forward-looking cost of staying, even when a superior alternative exists.
Marginal Analysis — Incremental effects.
Marginal Utility — Additional satisfaction.
Market Equilibrium
Maturity Mismatch — A system holds two-sided commitments whose durations differ — a short side that must be repeatedly refreshed against a long side that cannot accelerate — so it fails when refreshing stops, not because it lacks resources but because they are locked in durations longer than the moment requires.
Mechanism Design — Rule engineering.
Moral Hazard — Risk-taking under protection.
Network Effect — Value increases with users.
Opportunity Asymmetry — Agents possess unequal access to actions and favorable outcomes.
Opportunity Cost — Value of best alternative.
Optimal Stopping Rule — A rule maps a sequence of observations to a halt decision, trading the cost of stopping too early against stopping too late.
Optionality — The asymmetric value of having a choice—bounded downside, unbounded upside—without obligation to act.
Overton Window — A mobile range of positions that are currently sayable without social cost, with boundaries shifted by repeated exposure rather than argument.
Pareto Effect (80/20 Rule) — 80/20 distribution.
Pareto Efficiency — Optimal allocation.
Parkinson's Law — An elastic activity expands to fill its allocated resource container up to the binding constraint when no counter-pressure calls a stop short of the wall.
Path Dependence — Outcomes are shaped by the specific historical sequence of past choices, which lock in consequences and foreclose alternatives that persist despite present incentives to change.
Pivotality — An element whose participation is necessary for a collective outcome owns the marginal contribution and acquires leverage beyond its nominal share.
Preference — Agent's ordering over a choice set on some evaluative dimension.
Price Discrimination — Variable pricing.
Price Elasticity — Sensitivity to price changes.
Price Mechanism — Supply-demand pricing.
Property Rights — An enforceable bundle of exclusive entitlements over a resource.
Public Goods — Non-excludable goods.
Rent Seeking — Expending real resources to capture a larger share of existing value by working the rules that govern allocation, rather than to produce new value.
Resource Curse
Reversibility Horizon — Temporal threshold where reversal cost exceeds forward commitment.
Risk Aversion — Preference for certainty.
Risk Pooling — Aggregating many independent or weakly correlated exposures so that the variance of the pooled outcome shrinks below the sum of individual variances, letting participants share a more predictable collective risk.
Risk–Return Tradeoff — Risk vs reward.
Scarcity — A finite resource is insufficient to satisfy all competing wants.
Screening — Inducing self-revelation.
Shadow Of The Future — Expectations of continued interaction plus observability of past behaviour convert one-shot dilemmas into self-sustaining cooperation without contracts or altruism.
Signaling — Revealing hidden information.
Social Choice — Aggregate many agents' preferences into one collective outcome under a stated rule.
Specialization — Agents concentrate on a narrow range of tasks for efficiency.
Speculative Bubble — Self-reinforcing price rise detached from fundamental value.
Strategic Complementarity — One actor's action raises the marginal benefit of others taking the same action.
Strategic Substitute — One actor's action lowers the marginal benefit of others taking the same action.
Systemic Risk — Risk that local failures propagate into system-wide collapse.
Time Preference (Discounting Future) — Present vs future value.
Time Value of Money — Present vs future value.
Trade-offs — Balancing competing priorities.
Tragedy of the Commons — Resource depletion from self-interest.
Transaction Costs — Frictions in exchange.
Two Sided Market — A platform mediates two distinct user groups whose participation creates value for each other, so each side's marginal value rises with the other side's size and the two demand schedules must be balanced together.
Two-Sided Matching — Forming stable pairings between two sides of a market under each side's preferences.
War Of Attrition — A contest decided by who pays continuously the longest, with all paid cost sunk and the prize dissipated in the paying.
Wisdom of the Crowds — Many independent noisy signals combine into an estimate better than any individual (information aggregation).
Zero Sum Game — The total payoff across participants is fixed, so one party's gain is necessarily another's equal loss and the only strategic question is distribution.
