Nonlinear pricing and tariff differentiation: evidence from the British electricity market
journal contribution
posted on 2014-07-22, 12:21 authored by Stephen Davies, Catherine Waddams Price, Christopher WilsonChristopher WilsonLiberalisation of the British household electricity market, in which previously
monopolised regional markets were exposed to large-scale entry, is used as a
natural experiment on oligopolistic nonlinear pricing. Each oligopolist offered a
single two-part electricity tariff, but inconsistent with current theory, the two-part
tariffs were heterogeneous in ways that cannot be attributed to explanations such
as asymmetric costs or variations in brand loyalty. Instead, the evidence suggests
that firms deliberately differentiated tbeir tariff structures, resulting in market
segmentation according to consumers' usage.
