This paper tackles the complex issue of how buyers and sellers within a domestic carbon credit system designed to include regenerating indigenous forest would optimally design contracts for trades of the new good, “carbon sink credits”. The paper begins by briefly defining the constraints...

Carbon sequestration in plantation forests provides the main means by which New Zealand will meet its international climate change obligations in the first commitment period of the Kyoto Protocol (2008–2012). However, without active policy, forests are unlikely to contribute as much in...

Hendy and Kerr (2005b) find that an emissions charge on agricultural methane and nitrous oxide of $25 per tonne of carbon dioxide (CO2) equivalent would be likely to reduce New Zealand’s net land-use related emissions for commitment period one in the order of 3%, with full accounting. The...

We give the reader a tour of good energy optimization models that explicitly deal with uncertainty. The uncertainty usually stems from unpredictability of demand and/or prices of energy, or from resource availability and prices. Since most energy investments or operations involve irreversible...

The periodical re-auction of a water monopoly concession causes the danger of underinvestment. If the life-time of specific assets such as water pipes exceeds the contract length and transferring the ownership of assets is difficult, the incumbent franchisee faces a hold-up problem. Using a...

Due to the increasing discussion about liberalisation in the piped water industry municipal authorities in several European countries consider modifications of their water utilities’ structure such as legal constitution, business objectives or private participation. The purpose of this paper...

This paper surveys water pricing models, highlighting some important results. Efficiency rquires marginal cost pricing. Intra-annual price changes or customer differentiation to reflect differences in marginal costs can enhance efficiency. A marginal cost pricing mechanism may signal the value...

As tradeable permit programmes mature, two inter-related issues are becoming more critical in creating viable responses to a long-term, highly uncertain environmental problem such as climate change. First, we need to update policies in response to new information; and second, we need to design...

Tropical forests are estimated to release approximately 1.7 PgC per year as a result of deforestation. Avoiding tropical deforestation could potentially play a significant role in carbon mitigation over the next 50 years if not longer. Many policymakers and negotiators are skeptical of our...

Policy enabling tropical forests to approach their potential contribution to global-climate-change mitigation requires forecasts of land use and carbon storage on a large scale over long periods. In this paper, we present an integrated modeling methodology that addresses these needs. We model...
