BACKGROUND & AIMS Helicobacter pylori "test and treat" has been recommended for the management of young dyspeptic patients without alarm symptoms, and trials have suggested that it is as effective as endoscopy. However, none of these trials have had sufficient sample size to confirm that "test and treat" costs less or to detect small differences in effect. A collaborative group has prospectivel...

This paper addresses the relative suitability of nuclear and solar in Australia as a primary future electricity option, since nuclear can use abundant Australian resources of U235, but the direct solar option is the biggest global resource. The background is that we are likely to need generation systems which use close to zero net emissions by mid-century. There are many energy options, but few...

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...

The aim of this paper is to determine Korean consumers’ valuation for domestic rice and imported rice from China and the US. Using revealed preference data from random nth price auction mechanism, our results generally suggest that consumers’ willingness to pay (WTP) for domestic rice is higher than the WTP for imported rice. Results also suggest that while country of origin and food miles info...

In this study, we investigate the formation of bidder’s willingness to pay (WTP) in sequential online auctions. Our findings contribute to the literature of online auctions in the following ways. First, we detect and empirically measure in a real world scenario the WTP updating phenomenon mentioned by Engelbrecht-Wiggans (2000). By considering the environment of multiple sequential auctions of ...

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 study the optimal behaviour of a firm whose cash holdings are determined by a diffusion process and which is faced with the threat of liquidation if internal cash balances fall below some threshold. There is a conflict between the desire to pay out cash as dividends to satisfy relatively impatient shareholders and the need to retain cash as a barrier against possible liquidation (and consequ...

Abstract The main objective of net pay determination, as an important step any reservoir study, is to exclude non-reservoir intervals so that better results are obtained from characterization, hydrocarbon in-place calculations, and dynamic flow simulation the reservoir. This study a comprehensive presentation most applicable methods available for highlighting their strengths, limitations, input...
