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.


2016-02-02 – 'Valuing the benefits of improved marine environmental quality under multiple stressors' forthcoming in Science of the Total Environment.

We estimate the benefits to people in Estonia resulting from reductions in pressure from multiple stressors in the Baltic Sea. The main results show that, (1) respondents have a positive WTP to reduce each of the stressors analysed, (2) the average WTP for achieving Good Environmental Status is around 65 euro per household per year, and (3) the greatest share of value of this total economic benefit is derived from the reductions in the risk of large scale oil and chemical spills.


2015-12-30 – 'Marine trade-offs: comparing the benefits of off-shore wind farms and marine protected areas' forthcoming in Energy Economics.

We use choice modelling to investigate the relative gains and losses from siting new windfarms off the coast of Estonia, relative to the option of creating a new marine protected area. The paper also presents the first use of the latent class mixed logit model in willingness-to-pay space for environmental goods.


2015-10-11 – 'How Much do Switching Costs and Local Network Effects Contribute to Consumer Lock-in in Mobile Telephony?' forthcoming in Telecommunications Policy.

We aim at identification and measurement of switching costs and local network effects which lead to consumer lock-in in mobile telecommunications. Switching costs continue to affect consumer behavior despite the introduction of number portability. Local network effects represent a smaller, albeit significant, component of consumer lock-in.


2015-08-21 'Social norms, morals and self-interest as determinants of pro-environment behaviours: the case of household recycling' forthcoming in Environmental and Resource Economics.

We look at the role which selfish, moral and social incentives and pressures play in explaining the extent to which stated choices over pro-environment behaviours (household recycling) vary across individuals. A substantial share of the public prefer to sort their waste at home rather than in a central sorting facility. This preference is associated with a moral/intrinsic motivation, involving a belief that sorting at home is more thorough than central sorting.


2015-07-29 A function allowing for calculating the Minimum Tolerance Level.

The Maltab function calculates the MTL (error rate) allowing for a conclusion that two empirical distributions (e.g., distributions of WTP or measures of WTP estimated with uncertainty) are 'equivalent' at the 5% significance level. Particularly useful for Benefit Transfer.


2015-07-27 'Choice experiment assessment of public preferences for forest structural attributes' forthcoming in Ecological Economics.

The study investigates public preferences for recreational forests characteristics. The results indicate that respondents prefer older stands with vertical layering, irregularly spaced trees and a greater number of tree species. Forests that are managed (or left unmanaged) for biodiversity are also found more attractive. These results are much different from what much of the forestry management literature appear to think is preferred.
