Liberalisation of the British electricity market, in which previously monopolised regional markets were exposed to large-scale entry, is used to test the propositions of several recent theoretical papers on oligopolistic nonlinear pricing. Consistent with those theories, each oligopolist offered...

Despite the existence of two vast literatures, very little is known about the potential differences or interactions between search and switching costs. This paper demonstrates the benefits of examining the two frictions in unison. First, the paper shows how subtle distinctions between the two...

This paper demonstrates the incentives for an oligopolist to obfuscate by deliberately increasing the cost with which consumers can locate its product and price.  Consumers are allowed to choose the optimal order in which to search firms and firms are able to influence this order through their...

We report evidence of three types of consumer switching decision errors within the UK electricity market. We identify consumers who do not switch despite substantial available savings, consumers who switch from a cheaper to a more expensive supplier and consumers who switch to a cheaper, but not...

Within a one-shot, duopoly game, we show that firms cannot use false in- store price comparisons to deter rational consumers from further beneficial price search in an effort to create market power. However, by introducing a consumer protection authority that monitors price comparisons, we...

It is well known that search costs and switching costs can create market power by constraining the ability of consumers to change suppliers. While previous research has examined each cost in isolation, this paper demonstrates the benefits of examining the two types of friction in unison. The...

We develop a decision framework with imperfect information to analyze the effects of transaction costs on the tendency for individuals to remain with a default option. We demonstrate how transaction costs can be a more important source of such default effects than commonly thought. A further,...

This paper demonstrates that the ability of consumers to choose the best alternative supplier is limited even in a relatively simple and transparent market. Across two independent datasets from the UK electricity market we find, on aggregate, that those consumers switching exclusively for price...

This paper demonstrates the incentives for an oligopolist to obfuscate by deliberately increasing the cost with which consumers can locate its product and price. Consumers are allowed to choose the optimal order in which to search firms and firms are able to influence this order through their...
