2022-05-23 – 'Endogeneity and measurement bias of the indicator variables in hybrid choice models: A Monte Carlo investigation' forthcoming in Environmental and Resource Economics

We show that while hybrid choice models control for measurement error, dealing with endogeneity requires explicit accounting for in the model. We demonstrate the extent of the bias resulting from measurement error and endogeneity and propose new specifications of a hybrid model that account for different kinds of endogeneity.


2022-03-20 – 'Valuing externalities of outdoor advertising in an urban setting - the case of Warsaw' forthcoming in Journal of Urban Economics

We propose a theoretical model of positive and negative externalities associated with outdoor advertising and estimate the value of its reductions in Warsaw (1.7 to 4.1 million EUR per year for free-standing ads and 5.5 – 9.3 million EUR per year for advertising on buildings).


2022-03-09 – 'The relative performance of ex-ante and ex-post measures to mitigate hypothetical and strategic bias in a stated preference study' forthcoming in Journal of Agricultural Economics

We test the performance of ex-ante (cheap talk) and ex-post (option to modify responses) measures to account for hypothetical and/or strategic bias. The econometric analysis makes use of innovative semi-parametric logit-mixed logit in addition to the state-of-the-art mixed logit model.


2021-08-09 – 'Predicting uptake of a malignant catarrhal fever vaccine by pastoralists in northern Tanzania: opportunities for improving livelihoods and ecosystem health' forthcoming in Ecological Economics

We study Tanzania pastoralis' preferences and WTP for a new vaccine for MCF disease of their cattle. Vaccine's characteristics and price can be used to predict consumers' choices when the product is made available in the market, which we will verify in the near future.


2021-05-13 – 'Increasing the cost-effectiveness of nutrient reduction targets using different spatial scales' forthcoming in Science of The Total Environment

This multidisciplinary study investigates the potential gains in cost-effectiveness from changing the spatial scale at which nutrient reduction targets are set for the Baltic Sea, focusing on nutrient loadings associated with agriculture. A novel highly disaggregated model, which represents decreases in agricultural profits, changes in root zone N concentrations and transport to the Baltic Sea is proposed, and is then used to estimate the gains in cost-effectiveness from changing the spatial scale of nutrient reduction targets. The results have important implications for both domestic and international policy design for achieving water quality improvements where non-point pollution is a key stressor of water quality.


2021-05-10 – 'Information use and its effects on the valuation of agricultural genetic resources' forthcoming in Land Economics

This study looks at public preferences in Finland for conserving agricultural genetic resources. We investigate the demand for and the effects of information about unfamiliar public goods.


2020-12-01 – New book 'Environmental Valuation with Discrete Choice Experiments' published

This is our new textbook combining state-of-the-art guidance on design, implementation and data analysis for discrete choice experiments.
