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.

WP33. Testing sensitivity of willingness to pay for mortality risk reduction

Contingent valuation method was used in this study to elicit willingness to pay for risk reduction of dying because of cardiovascular or respiratory diseases. The survey was conducted on a sample of 408 citizens of Warsaw between 50 and 80 years of age. Obtained results did not pass external scope test, even in its weak form. The magnitude of risk reduction did not have statistical influence on the probability of accepting the bid.

WP3. How to 'Sell' an Environmental Good: Using Labels to Investigate Scope Effects

Insufficient sensitivity to scope remains one of the pivots of criticism addressed at validity of stated preference methods. Many studies demonstrate failure of a scope test of some sort, while many others show that WTP responses are sensitive to the scope of environmental change. Despite some existing explanations and reasons for insensitivity to scope (embedding, warm glow, uncertainty over supply of a public good, awareness of all options) there seems to exist no clear conclusion on how to deal with it. The paper provides an alternative explanation for insufficient sensitivity to scope, based on redefinition of value drivers of environmental goods. In the proposed framework respondents' WTP need not depend only on physical characteristics of a valued good but may also partly be a function of a 'label' under which the environmental good is 'sold'. To investigate this problem and empirically test the hypothesis and its implications, a CE study in a biodiversity valuation setting is designed and conducted. The conceptual framework and empirical evidence provide an alternative explanation for problems with the insufficient sensitivity to scope observed in many studies. Finally, we set out some implications of the nature of labels as value drivers for the design of future valuation studies.
