Estimates of willingness to pay (WTP) for health, environmental, and other goods obtained using contingent valuation (CV) have been criticized as inadequately sensitive to the scope or magnitude of the good. We investigate the sensitivity of WTP to variation in the magnitude of reductions in health risk using survey data collected in two countries, Taiwan and the United States, that differ dram...

This study analyzes consumers’ willingness to pay (WTP) for wind generated energy and examines how attitudes, deontological evaluation, and teleological evaluation affect WTP. Sparks and Pan (2009) suggest that future judgment research will benefit from integration between theories of ethical decision making and theories of social cognition. This paper utilizes Hunt and Vitell’s (1986) ethical ...

In this paper, we focus on efficiently achieving Proportional Delay Differentiation (PDD), an instance of the Proportional Differentiation Model first proposed under the DiffServ framework [IEEE Network (1999)]. PDD can be achieved using a few algorithms, one of the most well-known being Waiting Time Priority(WTP). Using WTP [Proc. ACM SIGCOMM (1999)] as a reference, we show that our proposed S...

The article presents the marginal willingness-to-pay (WTP) estimates for various qualitative and quantitative attributes of travel with reference to the bus transportation system in Kolkata City, India. A stated choice experiment is designed to capture the responses for estimating marginal WTP values for various attributes. WTP values are estimated separately for commuting and noncommuting trip...

A study was undertaken in southern peninsular state of India, the Tamil Nadu State, to assess the farmers’ “Willingness to pay” (WTP) for receiving annual health care services to their dairy animals. The districts of the state were categorized as “Livestock developed” (LD) and “Livestock under developed” (LUD) based on initial base line developed. Contingent valuation (CV) approach was used to ...

Health and safety are important factors in today’s life. Most of studies show that consuming the chicken that has anti biotic caused different diseases like digestive vessel cancer. Attention to controlled use of antibiotics can play a key role in society health which considered in the production of green chicken. Planning for increasing the production of mentioned chicken needs the investigati...

This study advances, and experimentally tests, a new explanation for the disparity between willingness to pay (WTP) and willingness to accept (WTA)—a dynamic neoclassical theory based on the presence of commitment costs. While to date neoclassical models have not explained the observed data patterns well, we find that the commitment cost theory is able to explain adequately the causes and sever...

The demand function for vaccines against typhoid fever was estimated using stated preference data collected from a random sample of 1065 households in Hue, Vietnam, in 2002. These are the first estimates of private willingness-to-pay (WTP) and demand functions for typhoid vaccines in a developing country. Mean respondent WTP for a single typhoid fever vaccine ranged from USD 2.30 to USD 4.80. M...

OBJECTIVE Recently, we have seen an increase in the number of studies that measured the willingness to pay (WTP) for medical services using the contingent valuation method (CVM) and evaluated the benefits of these services. This study aimed to measure the general public's WTP for cancer screening with positron emission tomography (PET) and to determine consumer characteristics that may affect t...

We model how to measure consumer willingness-to-pay (WTP) from an English or ascending first-price auction based on two general bidding premises: no bidder bids more than her WTP, and no bidder allows a rival bidder to win at a price that she is willing to beat. We thus impose no structural assumptions on rationality of bidders or sellers. The proposed model is general enough to include buy-it-...
