This study is the first to value the mortality risk incurred from wildlife reintroduction. We conducted choice experiments on wolf reintroduction in Hokkaido, Japan, in order to value the resulting mortality risk. This process involves three unique factors: the mortality risk is zero before the...

This article develops a valuation model to evaluate mortality probability changes under objective ambiguity, where multiple mortality probabilities are exogenously given. We construct the valuation model based on <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$$\upalpha $$</EquationSource> <EquationSource Format="MATHML"> <math xmlns:xlink="http://www.w3.org/1999/xlink"> <mi mathvariant="normal">α</mi> </math> </EquationSource> </InlineEquation>-maxmin expected utility to evaluate the reduction in...</equationsource></equationsource></inlineequation>

This article develops a nonparametric method to consistently estimate mean willingness to pay (WTP) in various discrete response valuation methods. The advantage of this method is that it can consistently estimate unconditional mean WTP with astonishing ease under some assumptions of the bid...

The purpose of this paper is to examine the most appropriate slaughtering time for deer from an economic perspective under the following conditions: (1) standard deer farming and temporal deer farming; (2) unit price of venison is constant and is a function of age in months (3) grazing and pen...

This paper investigates the influence of a change in attitude toward the sustainableresource use of wild animals that exist under a prey–predator relationship. We builda theoretical model in which use value (price value) and non-use value (for example,existence value) are incorporated; we then...
