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.

WP95. Controlling for overlap in matching

The overlap problem is crucial in propensity score matching. Recently, Crump et al. (2009) showed that trimming provides a simple and robust solution to the overlap problem. In this study, we use a simulation approach to show that trimming is inferior to the caliper mechanism. We show that in most cases, both techniques provide unbiased estimates, but trimming is less efficient.

WP94. The Impact of Individual Risk Preferences on Valuing Preservation of Threatened Species: an Application to Lynx Populations in Poland

A recent innovation in environmental valuation surveys has been to acknowledge the inherent uncertainties surrounding the provision of environmental goods and services and to incorporate it into non-market survey designs. So far, little is known about how people assimilate and respond to such uncertainty, particularly in terms of how it affects their stated valuations. In this paper we focus on the impact of risk preferences on people's investments in environment. Individual risk preferences are elicited through a standard, incentivized multiple price list mechanism and used as a independent variable in the analysis of a choice experiment valuing the preservation of two threatened lynx populations in Poland. We find that risk-seeking respondents were more likely to choose the status quo option, which was the riskiest option in terms of the survival of the two distinct lynx populations. Risk seekers revealed also a significantly lower willingness to pay for lynx preservations.
