When Are Impedance Choices Irrelevant? Equivalence Conditions for Hansen-Style Access Metrics
Abstract
Access indices often differ only by the impedance function f that downweights opportunities by travel cost. We give conditions under which different impedances (i) yield the same percentage responses in a standard planar benchmark, (ii) give levels that differ only by a multiplicative constant, and (iii) preserve cross-place rankings. We work fully in discrete form, so results apply to finite opportunity sets without measure notation.
