Technical Report
Full-text available
Choice experiments using route choice and social choice formats were used in a survey of over 7,000 individuals to derive monetary values for saved lives, reduced injuries, travel time and reliability of travel time. The study included private and public transport modes.
Technical Report

This report examines whether there are practical constraints to New Zealand achieving ambitious goals for the adoption of electric vehicles, from limits either to supply or demand. It includes constraints in the short run, to 2025, and the longer run, from 2030.

Benefit analysis of the New Zealand Government's policy proposals to restore and protect freshwater.
Technical Report

This research project examined whether a single new survey, and analysis of the data, could be used to obtain robust values for the monetary value of statistical life, prevented injuries, travel time savings, trip reliability and congestion. A review of approaches used elsewhere was followed by the design of a choice modelling survey and two rounds...
Research
Full-text available
This report gives guidance for empirical ex-post evaluation of projects, policies, and other interventions in the transport sector. We focus on statistical methods that are designed to estimate the effects caused by an intervention, known as methods of ‘causal inference’. There are many causal inference methods and we provide guidance for selecting...
Technical Report
Full-text available
This report explores options for market oversight of the New Zealand emissions trading scheme (ETS). It addresses whether there is a need for regulation of the market in a similar way to regulation of financial markets, to address potential or actual problems which include poor investment advice, limited market entry and market abuse.
Technical Report
Full-text available
This project aimed to identify the best approach for determining and monitoring the contribution that government regulatory interventions in New Zealand make to mitigate the major risks associated with the land transport system. It analysed the safety and environmental risks in the New Zealand road transport sector, and reviewed the local and inter...
Article
We analyze the household energy use impacts of a large-scale, universally available, subsidized retrofit insulation and clean heat scheme. Theory shows that the energy-saving effects of such schemes are ambiguous. Our difference-in-difference model of energy impacts resulting from each of insulation and clean heat treatment uses a sample of more th...
Conference Paper
Full-text available
Cities are complex. In the words of Edward Glaeser, cities are the absence of physical space between people and companies. Consequently, the actions of individuals and organisations in cities have (positive and negative) repercussions for people around them. Urban complexity therefore creates the potential for various market failures and regulatory...
Technical Report
Full-text available
We examined whether the charges for waste disposal in New Zealand reflect the full social, environmental and economic costs. Landfills are operated in New Zealand on a fully commercial basis, by local authorities, or under a private/public partnership. Generally charges are used to recover costs, but some landfills operated by councils include rate...
Technical Report
Full-text available
This report has a narrow scope for analysis; it examines the impacts on the industry supplying insulation and clean heating. It assesses:  the producer surplus associated with production and installation of insulation and clean heating;  additional employment in production and installation; and the  wider effects on employment elsewhere in the e...
Technical Report
Full-text available
This report examined appropriate discount rates for biodiversity offsets. Due to what is being replaced by the offset, the report recommends very low discount rates be applied for time discounting.
Technical Report
Full-text available
Bespoke pricing signals are one of the options identified within the Transmission pricing review (TPR). Covec has been asked by the Electricity Commission to explore this option and report on 1. Its background and rationale; 2. The nature and potential scale of benefits; 3. Implementation options; 4. The likely costs and benefits of these options r...
Technical Report
Full-text available
The purpose of this report is to provide the Parliamentary Commissioner for the Environment (PCE) with a set of “best guess” estimates for the carbon price in 2020 and 2030 for three climate policy scenarios that reflect a range of anticipated levels of global ambition in reducing emissions. The report is based on a review of projected prices in ex...
Technical Report
Full-text available
This report examines the current and expected future prices of coal in New Zealand for domestic and export markets. It is produced to provide data as input to forecasting and other modelling work by MED and other government agencies. The work has been based on industry interviews and analysis of published price data. Interviews have been held with...
Article
The inclusion of sinks in an emissions trading regime presents a number of challenges as the decisions under the Kyoto Protocol are clarified. However, because assigned amounts are defined in terms of an aggregate of six greenhouse gases and the contribution of absorption from sinks, it is not possible to eliminate its influence on permit price and...
Article
This paper questions whether current control of the pasture weed nassella tussock (Nassella trichotoma (Nees) Hack. ex Arech) is worthwhile, and how management can be improved. A computer model is developed to simulate nassella tussock population growth, and to provide a basis for calculating economic effects. The existing policy objective of eradi...

Sphagnum inhabits wet nutrient-poor mires usually in relatively open areas with short vegetation. The moss is harvested by hand pulling and dried before use. In New Zealand there are markets for little more than 5 t.p.a. The major markets are horticultural companies in Japan and 110 tonnes of dried product were exported in 1982 worth approximatly $...

Article
Phosphate rock is a strategic material upon which pastoral agriculture and all New Zealanders depend. Phosphate fertilizer has no close substitute, and is, therefore an important limiting factor to agricultural productivity. The future wellbeing of the country depends on its efficient acquisition, manufacture, distribution and use. This report is p...
