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...

The research programme on multiple job holding identified substantial discrepancies between the Census and HLFS series regarding the increasing level of rural multiple job holding 1981 to 2001. Furthermore, evidence from the Time Use Survey suggests that the distribution of second job...

This paper addresses the two main problems that Regional Fishery Management Organizations face. First, how to induce independent nations to reduce their fishing efforts from the competitive equilibrium to prevent the fish stock from extinction or to increase profits. We argue that adjustment...

The dependency of small island economies on natural resources coupled with the pubic nature of these resources means that sustainability is a topical issue especially when development projects offer opportunities for "better living" for communities. For a mangrove dependent community of...

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...

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...

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...
