Motu is currently developing a dataset of production costs relating to different rural land uses, which we can use to help explain historical land-use trends at a Territorial Authority level. The Meat and Wool Economic Service farm survey provides a rich database containing physical and...

The 2003 reform of the European Union's Common Agricultural Policy (CAP) replaced the coupled direct support schemes by a Single Farm Payment (SFP), which will be mainly delivered to farmers irrespective of what they produce (hence 'decoupled' from production). The level of decoupling differs...

In an idealised model the costs of capital and maintenance and the resulting flow of income benefits over a period of years enables the analyst to produce computations of present values and internal rates of return that summarise the whole investment process in a micro environment. In...

In New Zealand, the demand for nitrogen fertiliser has increased markedly since the early 1980s. Potentially, this trend has significant environmental and climate change implications. While many factors could contribute to this trend, little work has been done to examine the drivers of increased...

This article explores long-term land improvement (lime application) under land tenure insecurity on leased land. The dynamic optimisation problem is solved by a stochastic dynamic programming routine with known parameters for one-period returns and transition equations. The model parameters...

This paper assesses the distributional and economic impacts resulting from a hypothetical individual quota management system in the Gal�pagos spiny lobster fishery. Using data from the Fisheries Monitoring Programme, an implicit function is derived and evaluated at a total allowable catch to...

The greatest friction in trade and fishery between Japan and New Zealand was the Total Economic Relationship, which was insisted by the PM of NZ. NZ wanted to export dairy foods in exchange for admitting fishing. Both governments experienced a long and tough negotiation. Recently frictions have...

Lakes Taupo and Rotorua are important to New Zealand, but declining lake water quality is increasingly becoming a problem. Primary producers are said to be impacting heavily on the lakes' water quality through discharges that reach them through streams and ground water. The paper discusses the...

There are at least five general reasons why market-based policies fail to address some of the most basic environmental objectives. This study evaluates the available biophysical and economic data against these criteria and concludes that market-based approaches should be employed cautiously in...
