An elicitation format prevalently applied in discrete choice experiments (DCEs) offers each respondent a sequence of choice tasks. Each choice task contains more than two choice options. Empirical evidence shows, however, that repeated choice tasks influence choice behaviour through...

The key tasks in the design of a choice modelling (CM) experiment are to define the scope, scale and frame of the tradeoffs presented to respondents. This study explores the scale and scope of choice tasks and then develops definitions of these terms. The scope of a good in a stated preference...

Choice experiments (CE) are increasingly used as a stated preference technique to value changes in non-market goods. Respondents to a CE survey are asked to make repeated choices between alternatives. Each alternative is described by a number of attributes – the attributes levels vary across...

To elicit household willingness to pay (WTP) for improvements in environmental quality in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean), a choice modelling (CM) study was conducted. This report presents results of research designed to investigate variations in WTP across different...

This report compares evaluation frameworks for selecting landholder proposals to improve water quality. A water quality tender performed in the Burdekin region in Northern Australia in 2007/2008 was used as a case study. Tender bids can be assessed using an inputs-based best management practice...

Invasive species create particular challenges for policy makers .Some deliberately introduced species contribute significantly to agricultural production and other purposes. However, many invasive weed and animal pests generate substantial costs through impacts on agricultural production,...

This report presents results of research designed to investigate variations in willingness to pay (WTP) estimates across different scales and scopes of environmental investments. The goal is to help catchment management authorities better prioritise their natural resource management actions at...

The survey was designed to estimate environmental values suitable for integration into MOSAIC, a bio-economic model for catchment and farm level planning. Local residents, as well as distant rural and distant urban communities, were surveyed in three NSW catchments (Lachlan, Namoi and...

To determine whether the collection mode affects sample characteristics and value estimates, paper-based (using drop-off/pick-up) and web-based (using an internet panel) modes were tested. The exercise elicited values from Brisbane respondents for future environmental improvement of the Great...

There is demand for qualitative and quantitative economic analysis on the optimum degree of climate change mitigation and adaptation, the optimal timing of such actions, and their optimum distribution between countries and sectors. This paper discusses what is, as well as what is not, possible...
