Proton transfer reaction-mass spectrometry (PTR-MS) is a spectrometric technique that allows direct injection and analysis of mixtures of volatile compounds. Its coupling with data mining techniques provides a reliable and fast method for the automatic characterization of agroindustrial p w d t d c ©

Many transport policies and innovations are liable to have implications for human health and safety. How should such implications be weighed against the other costs and benefits? In particular, when policy makers are undertaking social cost-benefit analysis, what monetary value should be attached to any health or safety components? Standard welfare economics suggests that the answer should refl...

In the current study, we investigated the effects of several factors on the user’s willingness to pay (WTP) on hedonic social network sites (HSNSs), which includes WTP for HSNSs and WTP online contacts on HSNSs. Integrating the hedonic system use perspective with the social capital based view, we find that a user’s WTP for HSNSs is significantly positively influenced by the user’s perceived val...

Private provision of public goods has been investigated by many theoretical frameworks and experiments, most of which are difficult to apply in practice, let alone implement in the public sector. In this paper we offer a theoretical analysis of a Swedish government project's cost-sharing mechanism, which gave participants incentives to misrepresent their willingness to pay (WTP), some to unders...

This paper attempts to examine and measure ostomates’ preferences for improvements in ostomy pouches. Described are the study design, elicitation procedure and resulting preference structure of the Swedish ostomate sample. The method used to elicit the preferences is a Discrete Choice Experiment (DCE), where respondents are asked to choose between alternatives in choice sets. Each alternative i...

We examine entry decisions in first-price and English clock auctions with participation costs. Potential bidders observe their value and report maximum willingness to pay (WTP) to participate. Entry occurs if revealed WTP (weakly) exceeds the randomly drawn participation cost. While payoffs are higher in English clock auctions, we find no corresponding difference in WTP between auction formats,...
