Captive market¶
A market in which buyers have severely restricted practical alternatives because of monopoly, switching costs, location, compatibility, contracts, regulation, or control of access.
Core Idea¶
Captive-market power arises when a supplier controls a gate to demand and buyers cannot readily substitute, exit, defer, self-supply, or reach competing sellers, enabling price or quality terms above competitive levels. The constraint narrows the feasible supplier set, shifts bargaining surplus toward the gatekeeper, and can persist through lock-in, tie-ins, aftermarket dependence, or institutional placement. The abstraction is therefore identified by a declared carrier, a transformation or constraint over that carrier, and an invariant that tells an analyst whether the named structure is genuinely present.
Scope of Application¶
Captive market belongs to industrial organization and is useful where the analyst can specify the typed industrial organization carrier, defining objects and relations, parameters, conventions, evidence, boundary cases, and comparison targets, then evaluate product and geographic market, buyer group, alternatives, switching and exit costs, gatekeeper, constraint duration, price or quality effect, and counterfactual competition are explicit. The scope is broad within that domain but bounded by the need for product and geographic market, buyer group, alternatives, switching and exit costs, gatekeeper, constraint duration, price or quality effect, and counterfactual competition are explicit. The entry records a descriptive analytical identity; practical use requires the governing domain's evidence, standards, and safety obligations.
Clarity¶
The abstraction clarifies a crowded vocabulary by making product and geographic market, buyer group, alternatives, switching and exit costs, gatekeeper, constraint duration, price or quality effect, and counterfactual competition are explicit the center of the account. A claim should name the carrier, the governing operation or relation, the applicable assumptions, and the recognition test. A bare label is insufficient because the name Captive market can be used for a formal identity, an implementation, or a neighboring result unless carrier and convention are stated.
Manages Complexity¶
Without the abstraction, an analyst must reason directly over many local details: the carrier roles, admissibility assumptions, competing conventions, derived invariants, boundary cases, and proof or validation obligations specific to Captive market. Captive market compresses them into the roles in the structural signature. That compression permits comparison across instances without erasing the variables that determine validity. It also exposes which details may be varied safely and which are constitutive.
Abstract Reasoning¶
- Identify the carrier. State what the elements, states, objects, or observations are: the typed industrial organization carrier, defining objects and relations, parameters, conventions, evidence, boundary cases, and comparison targets. Reject examples whose alleged carrier belongs to a different problem. 2. Lock the constitutive rule. Express product and geographic market, buyer group, alternatives, switching and exit costs, gatekeeper, constraint duration, price or quality effect, and counterfactual competition are explicit independently of one notation or implementation.
Knowledge Transfer¶
Knowledge transfers strongly among subfields of industrial organization because they reuse the typed industrial organization carrier, defining objects and relations, parameters, conventions, evidence, boundary cases, and comparison targets, The constraint narrows the feasible supplier set, shifts bargaining surplus toward the gatekeeper, and can persist through lock-in, tie-ins, aftermarket dependence, or institutional placement., and type the carrier, state every parameter and convention in the definition, test that product and geographic market, buyer group, alternatives, switching and exit costs, gatekeeper, constraint duration, price or quality effect, and counterfactual competition are explicit, compare the nearest accepted identity, and report counterexamples, uncertainty, and limiting cases.

Neighborhood in Abstraction Space¶
Captive market sits in a crowded region of the domain-specific corpus (37th percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
