In many countries current water-pricing policies are dictated by the sole objective of breaking-even in each period. This results in large withdrawals which are not sustainable in the long-run hence not optimal. In this paper I derive the optimal dynamic water resource management policy of a...

Generators supplying electricity markets are subject to volatile input and output prices and uncertain fuel availability. Price-risk may be hedged to a considerable extent but fuel-risk - water flows in the case of hydro and gas availability in the case of thermal plants - may not be. We show...

This paper uses an equilibrium model of multipart nonlinear pricing to determine the magnitude of foregone profits due to the implementation of simple tariff options. I then use the available information from a cross-section of independent cellular telephone markets to study how these foregone...

Policy organizations such as the OECD and the EU have placed much emphasis on the role of local loop unbundling as a regulatory tool in stimulating the rollout and uptake of broadband technologies and consequently promoting the accrual of economic benefits from electronic commerce.

If New Zealand's EFTPOS networks receive stronger use than similar networks overseas because of differences in price structures what motivations lie behind the structures each has chosen? An analysis of the economic history of networks in New Zealand and a number of other developed countries...

The paper analyses more than ten thousand observations on prices charged for air travel on 1001 flights on eight New Zealand and twenty one trans-Tasman flights observed in 2004 and 2005. The main findings are (i) that routes on which Qantas competes with Air New Zealand tend to have air fares...

The Internet and associated networks and devices are intruding throughout social and commercial activity. They are improving information exchange storage and utilisation to an extent that is re-shaping the structure and institutions of society that have evolved over centuries inresponse to...

The Ultimatum game is simple and this facilitates its use in the study of predictions of game theory. Experimental evidence suggests that it doesnot predict individual behavior well unless individuals gain welfarefrom fairness in transactions or have expectations about some widergame. Our model...
