Females of the stream goby Rhinogobius sp. DA with paternal care favor males courting in fast water currents, whereby they mate males of high parental ability. Here we examined female choice of male nest size of this goby in laboratory. The dichotomous choice experiment clearly indicated that females prefer large nests. Spawning at large nests seems to improve egg survival rates in natural habi...

despite controversy, the contingent valuation method (cvm) is widely used for non-market valuation. among elicitation methods of cvm, the dichotomous choice (dc) has been paid attention. there are two types of dc methods: single-bounded dc (sbdc) and double-bounded dc (dbdc). dbdc is more efficient than sbdc. many of cvm studies in iran used dbdc but data analyses were done by logit model; that...

Restricted domains over voter preferences have been extensively studied within the area of computational social choice, initially for that are total orders set alternatives and subsequently dichotomous—i.e., correspond to approved disapproved alternatives. This paper contributes latter stream work in a twofold manner. First, we obtain forbidden subprofile characterisations various important dic...

Niagara Mohawk Power Corporation utilized a demand revealing public good mechanism to implement a green electricity program for provision of renewable energy and planting trees. This GreenChoiceTM program provided an opportunity to test the reliability of contingent valuation for predicting actual participation levels. In this study, participation levels predicted by hypothetical open-ended and...

We conducted a field experiment comparing hypothetical and real purchase decisions for a pharmacist provided asthma management program among 172 subjects with asthma. Subjects received either a dichotomous choice contingent valuation question or were given the opportunity to actually enroll in the program. Three different prices were used: US$ 15, 40, and 80. In the hypothetical group, 38% of s...

This study aimed to estimate the economic value of environmental services and establish Payment for Ecosystem Services (PES) scheme local communities in Janda Baik as financial incentives be involved conservation. The contingent evaluation method (CVM) that double-bounded dichotomous choice was used this
