Complex purchase protocols allow several participants (merchants and clients) to be involved within a single purchase transaction. Moreover, they provide the possibility to merge different heterogeneous payments into one atomic transaction. Although such complex purchases are urgently required, they are, so far, neither provided by existing protocols nor by available products or research protot...

In the literature it is suggested that the number of protest responses can depend on the valuation method. Choice Experiments (CE) are said to generate a lower number of protest responses than Contingent Valuation (CV). In a project about forest biodiversity both CE and CV were used and protest beliefs of all respondents irrespective of their willingness to pay determined. According to our anal...

This paper will present an e-procurement model to facilitate online B2B exchanges. Large organizations in Australia and around the world are increasingly implementing e-procurement, which has increased the need for services of intermediaries such as ‘emarkets’ to facilitate the process. However, both being new and unproven require theories and models to support their roles in the online procure...

Traditional economic valuation approaches assume that each individual has a single "true" value for a good or service in her mind that can be retrieved at will. Instead, we contend that an individual’s maximum willingness to pay (WTP) is best viewed as a random variable with an associated distribution. To measure individuals’ valuation distributions, we propose a new contingent valuation (CV) e...

Mass populations of toxin-producing cyanobacteria are an increasingly common occurrence in inland and coastal waters used for recreational purposes. These mass populations pose serious risks to human and animal health and impose potentially significant economic costs on society. In this study, we used contingent valuation (CV) methods to elicit public willingness to pay (WTP) for reductions in ...

This study quantitatively assesses two alternative explanations for inter-industry wage differentials: worker heterogeneity in the form of unobserved quality and firm heterogeneity in the form of the firm’s willingness to pay (WTP) for workers’productive attributes. We develop an empirical model of labor demand and apply a two-stage nonparametric procedure to recover worker and firm heterogenei...

Seceral contingent caluation studies hace found that the open-ended format yields lower estimates of willingness to pay (WTP) than does the closed-ended, or dichotomous choice, format. In this study, WTP for a public encironmental good was estimated under four conditions: actual payment in response to open-ended and closed-ended requests, and hypothetical payment in response to open-ended and c...

Retailers’ brands maker with private label have significantly boosted market share in recent years. Creating new brands for goods or services provide differentiation with similar distributors. The main aim of this paper is to test which component can be more effective in consumers’ purchase intention based on using private label for goods’ image. This research data was collected by prior st...

This study examines factors thought to influence consumers' planned and impulse purchase decisions including subjective culture (individualist or collectivist consumers) and the presence of another person at the time of purchase. Data was collected in four countries — the USA, Australia, Singapore, and Malaysia. The results indicate that overall, consumers are differentially influenced by other...
