A major limitation to the effectiveness of benefit-cost analyses of proposals involving natural ecosystems is the assertion of existence demand. Not only has confusion arisen regarding its exact definition but little has been done to establish its magnitude. Existence benefits are defined and an...

Choice experiments (CE) have become widespread as an approach to environmental valuation in both Australia and overseas. However, there are few valuation studies that have addressed natural resource management (NRM) changes in Tasmania. Furthermore, few studies have focussed on the estimation of...

Threshold Value Analysis (TVA) may be a useful input into natural resource decision making when non-market values are involved. The decision rule under a TVA is to protect a natural resource if the (non-marketed and unquantified) benefits so arising are deemed to be greater than a threshold...

What are the benefits of biodiversity protection? Why should those benefits be estimated? When should they be estimated … now or across future generations? Where should the benefits be estimated … locally, nationally or internationally? And, of course, how can they be estimated, if at all?...

The populist view of economic development and the environment is that advances in one will necessarily result in a decline in the other. Evidence in the Australian context is that the dual goals can be achieved simultaneously. As economic development progresses, the increasing levels of income...

This report proposes an extension to existing models of non-expected utility (NEU) in the stated preference (SP) literature. The extension incorporates the impact of multiple sources of ambiguity in individual decision making behaviour. Empirical testing of the proposed decision model was...

This study aims to show how Australian households perceive climate change and what they are prepared to do to reduce the harmful effects of climate change. A web-based survey in November 2008 asked approximately 600 New South Wales households about their willingness to pay additional household...

The extent of the benefits of improved river health remain uncertain. Quantifying these benefits is useful in prioritising policy investments. This study uses the Choice Modelling technique to estimate the value that households attach to attributes of improved river health. Data from a choice...

The lack of appropriate incentives through conventional markets is a major cause of deterioration of biodiversity on private land. In response, governments often intervene through changing the incentives faced by landholders. There are, however, potentially many ways that the incentives to...
