We propose a new approach, in which the VTTS is based on a stated-preference component of a travel cost survey. We find what people are willing to pay for time savings is largely unrelated to their hourly wage (or it's 1/3, as commonly assumed in revealed preference studies).
The article examines the role of Stated Preference valuation methods in the environmental economist’s toolbox. We make the case for using SP methods in a wide range of settings, showing how the approach can be used to both inform policy and gain a better understanding of people’s choices and preferences.
2019-04-18 – 'Farmers' preferences for nutrient and climate related agri-environmental contracts - a cross country comparison' forthcoming in AMBIO
We study farmers preferences for agri-environmental schemes related to nutrient loadings reductions and climate change mitigation in five countries around the Baltic Sea.
We investigate the extent of the simulation bias resulting from using different types and number of draws. We find that the number of the best-performing Sobol draws required for the desired precision exceeds 2,000 in some of the 5-attribute settings, and 20,000 in the case of some 10-attribute settings considered.
We propose a new specification of the MNL model that avoids the problems with standard error of the WTP calculated as a ratio of estimated variables (the problem manifests itself in small samples).
2018-12-20 – 'Personality and Economic Choices' forthcoming in Journal of Environmental Economics and Management
Do preferences for environmental goods depend on people's personality types? We test psychological theory predictions using data from three different empirical studies.
We study public preferences for various attributes of alternative fuel vehicles and selected policies to promote their uptake.
We point to different effects of policy and payment consequentiality in stated preferene surveys.
The paper reports on a neat experiment, in which we exogeously vary the amount of information provided to people with various levels of a priori information, in the context of flood protection in Scotland.
In this paper we investigate, if presenting the effects of policy options as uncertain influences people's preferences. It does, and the effects depend on whether gains or loses are considered.
