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.

WP312. Payment and policy consequentiality in dichotomous choice contingent valuation: Experimental design effects on self-reported perceptions

Although the contingent valuation literature emphasises the importance of controlling for respondents' consequentiality perceptions, this literature has rarely accounted for the difference between payment and policy consequentiality. We examine the influence of the randomly assigned tax amount on consequentiality self-reports and their potential endogeneity using data from a single dichotomous choice survey about reducing marine plastic pollution in Norway. Results show that consequentiality perceptions are a function of the tax amount, with payment consequentiality decreasing and policy consequentiality increasing with higher tax amounts. We discuss the challenge of finding valid instruments to address potential endogeneity of consequentiality perceptions.

WP260. Disentangling the effects of policy and payment consequentiality and risk attitudes on stated preferences

Incentivising respondents to truthfully reveal their preferences in stated preference surveys requires that they believe their survey responses can influence decisions related to the outcome in question (policy consequentiality) and that they will have to bear their share of coercive cost if the outcome is implemented (payment consequentiality). We investigate the effects of these two aspects of consequentiality on stated preferences in a field survey concerning renewable energy development in Poland. We find that beliefs in policy and payment consequentiality strengthen respondents' interest in having the project implemented, but policy consequentiality decreases, while payment consequentiality increases their sensitivity to the project cost, thus increasing or decreasing their willingness to pay, respectively. We conclude that the two components of consequentiality should be addressed separately in stated preference studies. Additionally, we inquire the theoretically speculated links between respondents' perceptions about policy and payment consequentiality and their risk attitudes, finding no significant relationship.

WP179. Addressing empirical challenges related to the incentive compatibility of stated preference methods

An emerging theoretical literature focused on the incentive compatibility of stated preference surveys offers a new lens through which to view extant evidence on external validity, and provides guidance for practitioners. However, critical theoretical assumptions rest on latent respondent beliefs, such as the belief that respondents view surveys as potentially influencing policy (i.e., policy consequentiality), which gives rise to pressing empirical challenges. In this study, we develop a Hybrid Mixed Logit model capable of integrating multiple latent beliefs, and subjective measures of these beliefs, into discrete choice models of stated preferences. Further, we provide a split-sample test of the effects of exogenous information signals related to policy consequentiality. Our results suggest some potential for researchers to induce desired beliefs through simple information signals and, importantly, that latent beliefs and information signals significantly influence elicited willingness to pay.
