Working Papers

Seria wydawnicza WNE WORKING PAPERS prowadzona jest przez WNE UW od 2008 r. i jak dotąd opublikowano w niej ponad 400 prac.

Seria WNE Working Papers służy szybkiemu upowszechnianiu wyników badań prowadzonych na Wydziale Nauk Ekonomicznych UW. Publikowane tu teksty mają charakter wersji roboczych (pre-printów): mogą być uzupełniane lub poprawiane w miarę postępu prac nad tekstem i procesu wydawniczego. Prezentujemy aktualną wersję udostępnioną przez autorów, opatrzoną datą oraz identyfikatorami DOI/ISSN – co ułatwia jej cytowanie i śledzenie kolejnych iteracji. Każdy dokument zachowuje pełne prawa autorskie swoich twórców, a w przypadku późniejszych zmian, autorzy mogą w dowolnym momencie zamieścić zaktualizowany plik lub wskazać miejsce ostatecznego wydania.

Do serii WORKING PAPERS przyjmowane są artykuły pracowników naukowych WNE UW oraz publikacje z konferencji organizowanych na WNE UW. Artykuły powinny dotyczyć ekonomii, mieć charakter oryginalnych prac badawczych, nie być wcześniej publikowane. Przyjmowane są wyłącznie teksty w języku angielskim.

WP227. Gain and loss of money in a choice experiment. The impact of financial loss aversion and risk preferences on willingness to pay to avoid renewable energy extarnalities.

We examine how the direction of price changes affects the value people place on avoiding renewable energy externalities in Poland. Additionally, we investigate the influence of individuals' financial loss aversion and financial risk preferences on this valuation. In our study we conduct a choice experiment survey in which respondents' choices indicate the value they place on avoiding wind, solar, and biomass externalities. We combine this survey with a financial lottery choice task that elicits the respondents' risk preferences and degree of loss aversion. In the choice experiment we use both increases and decreases in electricity bills to depict the uncertain effect of new sources of energy generation on the current price level. This design allows us to investigate if obtained values are independent of the payment mechanism. In the analyzed context, our results indicate that marginal utility of money seems to be lower with a rebate on the energy bill than with a surcharge. Moreover, financial risk preferences affect people's choices in a case of a surcharge, while loss aversion for money affects them in the case of a rebate. We find that the more loss averse people are with regard to money, the more they require compensation before they accept externalities from renewable electricity production. In contrast, the more risk seeking people are in a financial domain, the less cost sensitive they are and the more willing they are to pay for proposed changes in renewable electricity generation.

WP125. Wildfires in Poland: the impact of risk preferences and loss aversion on environmental choices

 This paper examines how risk preferences and loss aversion affect choices over a risky environmental good, wildfire prevention in Poland. We collect data in a stated preference survey that allows us to calculate both risk aversion and loss aversion parameters from individual respondents in both the financial and environmental domains. In doing so, we are able to confirm that this behaviour is consistent with prospect theory and holds for the majority of respondents. Additionally, we find little evidence of domain specificity of risk: responses to the financial risk questions were good predictors of responses to the environmental risk questions.

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.
