In contingent valuation, despite the fact that many externalities manifest themselves as costs to some and benefits to others, most studies restrict willingness to pay to being non-negative. In this paper, we investigate the impact of allowing for negative, zero and positive preferences for...

This paper investigates the sensitivity of choice experiment values for ecosystem services to "attribute non-attendance". We consider three cases of attendance, namely that people may always, sometimes or never pay attention to a given attribute in making their choices. This allows a series of...

Integrated Conservation and Development Plans (ICDPs) have been put forward as means of reconciling wildlife conservation in developing countries with improvements in community incomes. In this paper, we use the Choice Experiment approach to quantify overseas tourists' willingness to pay for...

Stated choice models based on the random utility framework are becoming increasingly popular in the applied economics literature. The need to account for respondents' preference heterogeneity in such models has motivated researchers in agricultural, environmental, health and transport economics...

In this paper, we investigate whether people's knowledge of the past influences their preferences and values towards future landscape change. "Knowledge of the past" is one aspect of the information set held by individuals, and a well-established finding in economics is that changes in...

Recent work by Kahneman and others has led to a new focus in economics on a wellbeing-based approach to utility. This suggests that ‘experienced utility' is an alternative and more appropriate basis for the measurement of economic value compared with ‘decision utility'. In this paper, we...

A range of empirical approaches to representing preference heterogeneity have emerged in choice modelling. Researchers have been able to explore the differences which selection of a particular approach makes to welfare measures in a particular dataset, and indeed have been able to implement a...
