What's new?

2019-06-09 –  'The Individual Travel Cost Method with Consumer-Specific Values of Travel Time Savings' forthcoming in Environmental and Resource Economics

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).


2019-05-07 –  'The Role of Stated Preference Valuation Methods in Understanding Choices and Informing Policy' forthcoming in Review of Environmental Economics and Policy

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.


2019-04-02 – 'Simulation error in maximum likelihood estimation of discrete choice models' forthcoming in Journal of Choice Modelling

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.


2019-03-09 – 'A new baseline model for estimating willingness to pay from discrete choice models' forthcoming in Journal of Environmental Economics and Management

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.


2018-12-02 – our Science Advances paper 'Baltic Sea as a time machine ...' covered in a popular article by the Washington Post


2018-11-12 – 'Electric, Plug-in Hybrid, Hybrid or Conventional? Polish Consumers’ Preferences for Electric Vehicles' forthcoming in Energy Efficiency

We study public preferences for various attributes of alternative fuel vehicles and selected policies to promote their uptake.


2018-11-10 – 'Disentangling the effects of policy and payment consequentiality and risk attitudes on stated preferences' forthcoming in Journal of Environmental Economics and Management

We point to different effects of policy and payment consequentiality in stated preferene surveys.


2018-09-03 – 'What is the Causal Impact of Information and Knowledge in Stated Preference Studies?' forthcoming in Resource and Energy Economics

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.


2018-06-22 – 'Stated Preferences for Conservation Policies under Uncertainty: Insights on the Effect of Individuals' Risk Attitudes in the Environmental Domain.' forthcoming in Environmental and Resource Economics

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.
