RATIONALE AND OBJECTIVES Economic theory classifies an intervention as socially beneficial if the total Willingness to Pay (WTP) of those who gain exceeds the total Willingness to accept (WTA) of those who are harmed. This paper examines the differences in health system users' valuation of a health care service in primary care setting based on the WTP and WTA perspectives, discussing the impact...

OBJECTIVE Access to healthcare is mostly contingent on out-of-pocket spending (OOPS) by health seekers, particularly in low- and middle-income countries (LMICs). This would require many LMICs to raise enough funds to achieve universal health insurance coverage. But, are individuals or households willing to pay for health insurance, and how much? What factors positively affect WTP for health ins...

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. In other words, we propose a " no regret " rule in bidding. Other than that, we do not impose restrictive assumptions on maximands or ...

Many empirical studies have demonstrated large discrepancies between willingness to accept (WTA) and willingness to pay (WTP) measures. This paper examines the extent to which uncertainty about the environmental quality improvement can lead to a divergence between WTP and WTA measures. Indirect utility function parameters and uncertainty about the environmental quality change affect the extent ...

Contingent Valuation is now the most widely used method for valuing non-marketed goods in cost benefit analysis. Yet, despite the fact that many externalities manifest themselves as costs to some and benefits to others, most studies restrict willingness to pay (WTP) to being non-negative. This paper explores appropriate welfare measures for assessing losses and gains and demonstrates how these ...

BACKGROUND The extra-welfarist theoretical framework tends to focus on health-related quality of life, whilst the welfarist framework captures a wider notion of well-being. EQ-5D and SF-6D are commonly used to value outcomes in chronic conditions with episodic symptoms, such as heavy menstrual bleeding (clinically termed menorrhagia). Because of their narrow-health focus and the condition's per...

A field test of cheap talk and two types of certainty calibration in contingent valuation of public lands indicated that cheap talk does not reduce WTP estimates. Use of a ten point certainty calibration scale reduces WTP estimates by about half. However, adjusting for uncertainty using a ‘Not Sure’ option does not reduce WTP estimates but increases the variance in responses. There may be a con...

INTRODUCTION The incremental cost-effectiveness ratio (ICER) is typically compared with a reference value to support the cost-effectiveness of a decision. One method for estimating this value is to estimate the willingness-to-pay (WTP) for a quality-adjusted life-year (QALY). This study was conducted to explore the WTP for a QALY in the Malaysian population. METHODS A cross-sectional, conting...

Random coefficient models such as mixed logit are increasingly being used to allow for random heterogeneity in willingness to pay (WTP) measures. In the most commonly used specifications, the distribution of WTP for an attribute is derived from the distribution of the ratio of individual coefficients. Since the cost coefficient enters the denominator, its distribution plays a major role in the ...

A distinction is drawn between opportunity cost and willingness-to-pay (WTP) valuations of the environment and the latter are shown to be appropriate only in situations where no agreed environmental standards exist. WTP measures of environmental effects form the basis of the Pigovian model of externalities. This model is applicable where individuals directly perceive environmental effects as nu...
