2017-04-23 – 'Gain and loss of money in a choice experiment. The impact of financial loss aversion and risk preferences on willingness to pay to avoid renewable energy externalities.' forthcoming in Energy Economics

We test if marginal utility of money is constant with respect to gains and loses and explore the extent to which they are affected by loss and risk aversion of an individual.


2017-04-19 – 'Re-examining empirical evidence on stated preferences: Importance of incentive compatibility.' forthcoming in Journal of Environmental Economics and Policy

We review empirical studies devoted to testing validity of stated preference methods. We find that studies that satisfy the necessary conditions for incentive compatibility (coercive payment mechanism, consequentiality, etc.) consistently show that stated preference methods can provide valid estimates of preferences and willingness to pay.


2017-03-15 – 'Designing a Socially Efficient Cultural Policy: The case of municipal theaters in Warsaw.' forthcoming in The International Journal of Cultural Policy

We investigate socially preferred ways of allocating public resources in the context of the types of performances offered by municipal theaters in Warsaw. We find that willingness to pay for introducing a program of highly discounted tickets exceeds the costs. We also find that the cost-benefit relationship varies across theaters with different types of plays in their repertories. Our results imply a different level of socially efficient support for experimental, drama, children’s and entertainment theaters.


2017-03-10 – 'Are bilateral conservation policies for the Białowieża Forest unattainable? Analysis of stated preferences of Polish and Belarusian public' forthcoming in Journal of Forest Economics

We are trying to find out and compare preferences towards increased protection of domestic and foreign segments of the Białowieża Forest, stated by samples of Polish and Belarusian citizens. Whilst Poles on average are willing to pay for an increased passive protection, on their side of the border, most Belarusians seem to be satisfied with the status quo. There is even an apparent mutual disutility derived from the perspective of co-financing bilateral passive protection programmes in the Białowieża Forest.


2017-01-15 – 'Understanding the distribution of economic benefits from improving coastal and marine ecosystems' forthcoming in Science of the Total Environment

We show how to use hybrid choice models framework to account for respondents' preference heterogeneity which can be linked to their socio-demographic characteristics. The application looks at value of reaching Good Ecological Status of Latvian marine waters.


2017-01-07 – 'Choosing a functional form for an international benefit transfer: Evidence from a nine-country valuation experiment' forthcoming in Ecological Economics

We point to choosing a particular functional form as an important factor influencing the performance of benefit transfer. The fact that using value transfers adjusted for income elasticity outperforms function transfers in our and a few other studies is an indication that function transfers do not typically pay necessary attention to mathematical functional form and there is currently no theory available to guide researchers in deciding what the relationship is between two sites based on data observed within one site only, particularly if the sites differ in income or other characteristics.


2016-10-13 – 'Public Acceptability of Climate Change Mitigation Policies: A Discrete Choice Experiment' forthcoming in Climate Policy

We examine the public acceptability of the EU’s future climate change mitigation policies looking at emission reduction targets, burden sharing across the EU Member States, the distribution of costs within each country, and cost to households. Our results reveal stark differences in preferences between the analysed countries.


2016-10-05 – '5’th Workshop on Discrete Choice Modelling, Warsaw, 2016'

We are organizing the next event in this series at the University of Warsaw. You can acsess the program and the presentations from here.


2016-06-19 – 'Preference and WTP stability for public forest management' forthcoming in Forest Policy and Economics

We test for the stability of preferences and WTP for attributes of forest management both within one survey and between two different moments of time. We reject the strictest test of the equivalence of WTP distributions. However, we also find that respondents' mean WTP is fairly stable and differences are mainly driven by the changes in variances and imperfect correlations of individual-specific WTP.


2016-06-17 – 'Sad or Happy? The effects of emotions on stated preferences for environmental goods' forthcoming in Environmental and Resource Economics

Do experimentally inducied incidental emotions affect human choices and values observed in discrete choice experiments? We find – not so much.


2016-06-11 – 'Spatial heterogeneity of willingness to pay for forest management' forthcoming in Environmental and Resource Economics.

What is the spatial heterogeneity of public’s preferences for the implementation of a new country-wide forest management and protection program in Poland? We use spatial econometric methods and high resolution GIS data related to forest characteristics in respondents' locations to find out how they influence individual-specific WTP values, derived from a DCE study.


2016-05-31 – 'Is the income elasticity of the willingness to pay for pollution control constant?' forthcoming in Environmental and Resource Economics.

The paper explores both theoretically and empirically whether or not the willingness to pay for pollution control varies with income. Our model indicates that the income elasticity of the marginal WTP for pollution reduction is only constant under very restrictive conditions. Our empirical analysis employs a multi-country contingent valuation study of eutrophication reduction in the Baltic Sea and finds that the elasticity is not constant. This has implications for how Benefits Transfer exercises, and for theoretical explanations of the Environmental Kuznets Curve.
