Working Papers

The WNE Working Papers series has been published by the Faculty of Economic Sciences at the University of Warsaw since 2008.

The WNE Working Papers series provides a fast, open channel for disseminating research conducted at the Faculty of Economic Sciences, University of Warsaw. The papers hosted here are working versions (pre-prints) and may evolve as authors refine their analyses, incorporate feedback, or progress through formal peer-review. What you read is the current version released by the authors, timestamped and assigned DOI/ISSN identifiers to ensure precise citation and version tracking. Copyright remains with the authors, who may, at any time, upload a revised file or add a note directing readers to a later, peer-reviewed publication.

The Working Papers series accepts articles by research employees of the Faculty and publications from conferences organised at the Faculty of Economic Sciences at the University of Warsaw. Articles should be original research papers which have not been previously published, on the subject of economics.

WP292. Role of information in the valuation of unfamiliar goods—the case of genetic resources in agriculture

The paper uses data from a discrete choice experiment to examine information effects on stated preferences for an unfamiliar environmental good, i.e. agricultural genetic resources. We define two groups of respondents based on their use of additional information provided in an internet survey, and model information use and its effect on individual preferences and scale using the logit and mixed logit models. Our findings indicate that both sociodemographic and attitudinal variables affect the use of information, with the respondent's age, gender, familiarity and perceptions of stakeholder responsibilities having a significant effect. The results show individual preference heterogeneity, but no significant differences in scale between the information groups after allowing the mean coefficients for the attributes to differ. Those who have used the additional information derive higher utility from the changes in the protection of agricultural genetic resources. Our results highlight the importance of genetic resource conservation and controlling for the effects of information use in choice experiment models for unfamiliar goods.

WP76. More random or more deterministic choices? The effects of information on preferences for biodiversity conservation

For many years, stated preference researchers have been interested in the effects of information on willingness to pay for environmental goods. Within the random utility model, information about an environmental good might impact on preferences and on scale (error variance), both between and within samples of choices. In this paper, we extend the G-MNL model to investigate the effects of different information sets on choices over the management of biodiversity in the UK, looking specifically at moorlands managed for red grouse shooting. Specifically, we make the individual scale parameter a function of observable (dataset-specific) characteristics. Our results show that changing information sets results in significant differences in the mean scale between datasets, and in the variance of scale. Respondents are more deterministic in their choices and show lower within-sample scale heterogeneity in the alternative information treatment. Changes in information provision also effect willingness to pay estimates, reducing the value people place on the conservation of two iconic birds of prey. The methods used will also be of interest to researchers who need to combine choice experiment data sets.
