The use of dichotomous choice questions (Are you willing to pay $x?) has been advocated as superior to open ended questions (What would you be willing to pay?) in contingent valuation studies of non-market goods. A supplementary dichotomous choice question, raising or lowering the bid price...

This paper explores alternative techniques for the selection of conservation contracts under competitive tendering programs. Under these programs, purchasing decisions are often based on the benefits score and cost for proposed projects. The optimisation problem is to maximise the aggregate...

Duration Analysis, which allows the timing of an event to be explored in a dynamic framework, is used to model the adoption of organic horticultural technology in the UK. The influence of a range of economic and non-economic determinants is explored using discrete time models. The empirical...

Best-worst scaling (BWS) is an increasingly popular method to assess preferences in environmental management. BWS provides more information per choice task, because respondents provide information about their best and worst choices. An important assumption is that their utility function is the...

The economic value of irrigation water to horticultural producers in southern Spain is examined using a choice experiment. Marginal water values are found to be typically above those currently paid and to increase with holding size. Potential gains from trade are identified but this would entail...

Up to 60 per cent of potable water supplied to Perth, Western Australia, is extracted from the groundwater system that lies below the northern part of the metropolitan area. Many of the urban wetlands are groundwater-dependent and excessive groundwater extraction and climate change have resulted...
