This paper is the first in a symposium of papers that examine the 2009 report by Frank Wolak into the New Zealand electricity market. The Wolak report concluded that there had been a cumulative total of NZ$4.3 billion of overcharging in the New Zealand wholesale market over a period of seven...

This paper is the second in a symposium of papers that examine the 2009 report by Frank Wolak into the New Zealand electricity market. In this paper, we discuss the Report's measures of the ability and incentives of generators to exercise unilateral market power. We show that the construction...

The recent Wolak report on the New Zealand electricity market found evidence of substantial market power. The report, an empirical one, was heavily criticised on several aspects of its methodology. We investigate market power in the New Zealand Electricity Market during 2006 and 2008 using an...

Modelling price formation in electricity markets is a notoriously difficult process, due to physical constraints on electricity generation and transmission, and the potential for market power. This difficulty has inspired the recent development of bottom-up agent-based algorithmic learning...

New technologies allow perfect detection of environmental violations at near-zero marginal cost, but take-up is low. We conducted a field experiment to evaluate enforcement of water conservation rules with smart meters in Fresno, CA. Households were randomly assigned combinations of enforcement...

The fixed-price-offer (FPO) mechanism in <italic>Trade Me</italic> auctions allows sellers to make a take-it-or-leave-it offer at the conclusion of an unsuccessful auction. Weinvestigate the effects of the FPO option on strategies and outcomes in independent-value auctions. The FPO option induces some bidders...

This article is concerned with models in which an agent faces a lottery with <italic>j</italic> other agents for a prize, so that the probability of winning the prize is 1/(<italic>j</italic> + 1), and where <italic>j</italic> is stochastic. After describing four different situations where such a lottery is present, we construct the expected...
