Individuals are widely believed to overstate their economic valuation of a good by a factor of two or three. This paper reports the results of a meta-analysis of hypothetical bias in 28 stated preference valuation studies that report monetary willingness-to-pay and that used the same mechanism...

Die Ertragskrise der Forstwirtschaft wirkt indirekt auf das Erholungsangebot des Waldes. Erholungsleistungen, die früher problemlos aus erwirtschafteten Überschüssen bereitgestellt werden konnten, werden in jüngerer Zeit mehr und mehr hinterfragt: Es ist daher naheliegend und von Interesse,...

The first essay developed a respondent model of Bayesian updating for a double-bound dichotomous choice (DB-DC) contingent valuation methodology. I demonstrated by way of data simulations that current DB-DC identifications of true willingness-to-pay (WTP) may often fail given this respondent...

In this paper an attempt is made to identify the socioeconomic characteristics of a community that influences the development and management of culture-based fisheries in village reservoirs of Sri Lanka. Socioeconomic data were collected from 46 agricultural farming communities associated with...

The thesis develops flexible Bayesian choice models and these models are often highly-parameterised. All inference is obtained from the posterior density and evaluated using computationally intensive Markov chain Monte Carlo (MCMC) estimation. The models are applied to health economics studies...

Based on hypothetical responses originating from a large-scale survey among about 6,000 German households, this study investigates the discrepancy in willingness-to-pay (WTP) estimates for green electricity across single-binary-choice and open-ended valuation formats. Recognizing that...

A contingent valuation method is applied to study subjects' willingness to pay for originals when illegal copies are freely available. The subjects consisted of 234 Swedish undergraduate students from the "computer generation". Only 2% of the "normal" (and 0% of the "elite") students were...

The primary objective of this study was to estimate the willingness to pay (WTP) for a new intervention at the workplace: wholesome canteen takeaways (CTA), i.e. a low fat meal with a large amount of vegetables prepared at the workplace canteen that only requires re-heating. The contingent...

The Value of a Statistical Life (VSL) is a widely used measure of the value of mortality risk reduction. Since VSL should reflect preferences and attitudes to risk, there are reasons to believe that it varies depending on the type of risk involved. It has been argued that cancer should be...

For the assessment of value of new therapies in healthcare, Health Technology Assessment (HTA) agencies often review the cost per Quality-Adjusted Life-Years (QALY) gained. Some HTAs accept a higher cost per QALY gained when treatment is aimed at prolonging survival for patients with a short...
