We present a model featuring irreversible investment, uncertain future demand and capital prices, and a regulator who sets the firm's output price at discrete intervals.

We show that regulators' price-setting, rate base, and allowed rate of return decisions are inextricably linked.

The Ultimatum game is simple and this facilitates its use in the study of predictions of game theory. Experimental evidence suggests that it does not predict individual behavior well, unless individuals gain welfare from fairness in transactions, or have expectations about some wider game. Our model excludes any notion of fairness by including (potential) rivalry in transactions. In this game the proposer's expectations yield outcomes that are consistent with experimental evidence. Offers can be large or small, with none in an intermediate range. The consequent distribution appears in Dictator game experiments. Our model explains how it is generated by expectations.

We show thast if cooperative's shares are priced at the present value of expected dividends and supplier entry and exit decesions are taken solely on the basis of profitability of membership then there is no ineffeciency and we describe a functioning example. Finally, our valuations show that there is no "time horizon" investment problem, at least from an industry prospective.

In this paper, we undertake a detailed analysis of the approach followed in LINES. We do so from the perspective of a referee who has been asked to provide a review of that report in order to assess its suitability for publication in an edited book or journal that adheres to conventional academic standards. Although LINES has not, of course, been submitted for publication or
review of this kind, its contents and recommendations should nevertheless meet minimum standards of accuracy, thoroughness and consistency. It is these criteria we use to assess LINES.

In this article we consider the tradeable property rights framework as a method of allocating water. Our objectives are to explain why such an approach can improve aspects of New Zealand's current water allocation framework, to establish the appropriate set of institutional arrangements for a tradeable rights framework to operate effectively, and to examine what may influence the value of tradeable water rights.

This paper considers the application of competition law and price regulation in
the very small, and isolated economy that is New Zealand. It argues that the total surplus (efficiency) criterion should be applied in tests of practices and actions where the competition threshold is not met or doubtful. Further, it argues that this criterion is admitted, if not required, under New Zealand statutes. The differential treatment of affected parties, including foreign investors, in measuring the surplus is considered.
