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.

WP519. Biodiversity-oriented forest management aligns with societal preferences across Europe

Forests across Europe are undergoing rapid transformation as biodiversity loss and climate change reshape priorities for forest management. Strategies that promote biodiverse and structurally complex forests are increasingly advocated to enhance ecological resilience, yet they are often assumed to conflict with societal preferences, potentially limiting public support for conservation and restoration. We examined whether forest characteristics associated with biodiversity conservation and climate adaptation are consistently valued by society across Europe. We combined a visual discrete choice experiment involving 11,622 respondents from twelve European countries with a travel cost model to evaluate whether stated societal preferences were reflected in observed recreational behaviour. We then integrated harmonized preference estimates with continental forest inventory and remote-sensing data to map the spatial distribution of societal values associated with forest ecosystem condition. Across all countries, respondents consistently preferred forests characterized by taller canopies, greater tree-species richness, heterogeneous age structures, and more deadwood. These preferences closely aligned with observed visitation behaviour despite substantial differences in geography, accessibility, and recreational traditions. Spatial analyses further showed that forests with greater structural complexity consistently exhibited higher societal value. Our findings demonstrate that biodiversity-oriented forest management and societal values largely converge across Europe, suggesting that many interventions promoting ecological resilience can simultaneously strengthen public support for forest conservation and restoration, providing a stronger foundation for adaptive, multifunctional forest governance under global environmental change.

WP516. When Risk Information Changes the Trip: Evidence from a Randomized Panel Combining Discrete Choice and Travel Cost Methods

Coastal bathing delivers large welfare benefits but exposes recreationists to low-probability, high-salience microbial risks that are likely to become more frequent under climate change. Because these risks are largely invisible, behaviour and welfare depend on beliefs and the effectiveness of risk communication. We provide causal evidence on how pathogen-risk information affects preferences and recreation demand using a three-wave panel survey of users of the Gulf of Gdańsk and the Vistula Lagoon (Poland). A stratified national sample identified 3,312 active coastal users in Wave 1 (spring 2024); 2,588 respondents returned in Wave 2 (summer 2024), where they were randomly assigned to receive either minimal information or increasingly detailed pathogen-risk scripts, and then completed a repeated beach-site discrete choice experiment. Approximately one year later (spring 2025), 1,507 users completed a policy-referendum discrete choice experiment on programs combining water-quality improvements, monitoring frequency, and household costs, alongside a repeated travel-cost module capturing multi-day trips and beach outings. Information treatments significantly increased objective and self-assessed knowledge and selectively raised willingness to travel/pay for risk-relevant attributes – especially frequent water-quality monitoring and water-quality improvements – while leaving unrelated attributes largely unchanged. Travel-cost models indicate that information affects trip-taking behaviour, yet the marginal travel-cost sensitivity remains stable, consistent with a demand shift rather than a change in the “price” slope. The results imply that welfare estimates are information-dependent and that credible risk communication can function as a scalable, low-cost complement to traditional coastal health-risk management.

WP77. The economic value of a White Stork nesting colony: a case of 'stork village' in Poland

In this paper we estimate the economic value of selected ecosystem services provided by White Storks in a Polish 'stork village'. A stork village is a common name for a village with a White Stork breeding colony, often inhabited by more storks than people. Zywkowo, the best known stork village in Poland, receives 2000-5000 tourists annually, many of whom come from abroad. The village has about 20-40 White Stork nests and several amenities aiming at improving its recreational attractiveness. To estimate the economic benefits provided by the stork village we apply the travel cost method. This is the first study of this kind for a stork village, and the first study related to the value of birds in Poland. Our results provide a useful input into policy and decision making, indicating that nature has economic value. It also serves as a clear illustration that degradation of nature may entail economic losses.
