# Contested concept: coase theorem

_**What you are reading**: one contested-concept page in Deliberus's deliberation graph. Deliberus maps human reasoning — including claims that are contested, mistaken, or extreme — so that disagreement can be examined precisely. A claim's presence here is not an endorsement: the graph records that someone argued it, how it connects to other reasoning, and how far scrutiny has gotten. The metadata on this page describes the state of that scrutiny, not the truth of the claim._

---

- **Contestedness**: semantic
- **Diagnosis**: Critics and defenders often talk past each other. Empirical refutations attack the efficiency or invariance versions, while Coase himself intended a warning about costs. The reading of the theorem determines whether 'inapplicability' is a criticism or the point.
- **Canonical**: `/concept/coase theorem` (data: `/concept/coase theorem.json`)

## Senses in use
- **A lesson that transaction costs cannot be neglected, so the initial allocation matters and institutions must be compared. The theorem itself concerns only the zero-cost case.** — used in 5 claim(s)
- **Efficiency/invariance: with low transaction costs, bargaining yields an efficient outcome regardless of the initial allocation.** — used in 4 claim(s)
- **Equivalence: contracts, markets and taxes are equally capable of internalizing an externality, given bilateral spillovers and equivalent rights.** — used in 4 claim(s)
- **A comprehensive state-owned macroeconomic framework in which the state manages the nation as a single firm.** — used in 3 claim(s)
