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.

WP527. Does the messenger matter? Scenario credibility and information source in valuing health risk reductions from air pollution

Perceived realism of the policy scenario presented in stated preference (SP) valuation depends on trust in the scientific soundness of the projected policy outcomes (epistemic credibility) and in policymakers' capability to deliver them (implementation credibility). Using a discrete choice experiment (DCE) with 1,100 Polish urban residents, we examine how policy scenario credibility shapes preferences for air pollution mitigation reducing risks from chronic obstructive pulmonary disease (COPD). We contrast domain experts and artificial intelligence (AI) with no-source control as information sources on policy outcome projections. We find that epistemic and implementation credibility are strongly correlated; thus, we treat credibility as a single variable affecting preferences. Using a hybrid mixed logit (HMXL) model, we demonstrate that higher perceived credibility increases programme support, lowers cost sensitivity, and thus elevates willingness to pay (WTP) for the programme and morbidity risk reduction. We find no evidence that the information source influences preferences or scenario credibility.

WP433. The impact of justice attitudes on air quality valuation: a study combining factorial survey and choice experiment data

In this paper, we investigate the effect of respondents’ attitudes concerning distributive justice in payments on their stated preferences for programmes reducing ambient air pollution in four cities in Poland. By combining two multi-factorial survey experiments, we propose a novel approach of incorporating justice attitudes into non-market valuation. In the first experiment – a factorial survey experiment (FSE) – we record justice attitudes towards payments. In the second experiment – a choice experiment (CE) – we elicit stated preferences for air pollution reduction programmes. As a modelling framework, we employ a hybrid choice model. The same respondents undertook both experiments in separate surveys one to two weeks apart, minimising the likelihood of biased estimates of the effect of justice attitudes on stated preferences. The results indicate a substantial effect of the justice attitude on the stated willingness to pay. The proposed approach could be used for joint modelling of justice attitudes and preferences in a wide range of fields, contributing further insights into their interactions.

WP82. Did people "buy" what was "sold"? A qualitative evaluation a Contingent Valuation survey information set for gains in life expectancy

A number of stated preferences studies have quantified the value of gains in life expectancy from pollution control and use a Value of a Life Year (VOLY) approach to calculate the value placed on avoiding premature mortality following exposure to such pollution. However, life expectancy gains are a complex concept and no attempt has been made, to date, to investigate peoples' understanding of what it is they are being asked to value. This paper uses a structured debriefing exercise to qualitatively investigate an approach which explicitly emphasises how this gain is delivered. We find that, for the majority of respondents, the approach is effective in communicating the ongoing nature of the gain and reduces the use of the (incorrect) heuristic that it is an 'add-on' at the end of life, in poor health. Further refinements are required, however, to communicate the cumulative nature of these risk reductions and the lack of impact on quality of life.
