Abstract

We appraise the theoretical basis and the consequent empirical work of Frank Wolak in his study of the New Zealand Electricity market in a report to the New Zealand Commerce Commission released in March 2009. The report found no multilateral actions, but concluded there was evidence of market power. We find that the theoretical and empirical methodologies employed do not imply the existence of unilateral market power in oligopoly electricity markets.

Keywords: electricity markets, market power
