since the promenades allocate the part of the country's revenues, therefore, attention to its valuation is very important. springs in desert area are the most prominent of natural landscapes. more study in country investigates recreational value using double– bounded dichotomous choice. but in this study, single-bounded dichotomous choice has been used because of this approach is more like...

this study determines the consumers’ willingness to pay for organic milk in tehran by using contingent valuation method and single bounded dichotomous choice questionnaire. logit regression model was used to evaluate the effect of explanatory variables on willingness to pay and the model parameters were estimated by using maximum likelihood approach. for this purpose, 450 questionnaires were co...

One of the most commonly observed anomalies in Double Bounded Dichotomous Choice is that of internal inconsistency between the estimated values derived by single bounded and double bounded methods from the same data set. This paper introduces a simple bootstrap method to test the significance of such differences. We add to the idea that the willingness to pay (WTP) differences between Single Bo...

abstract researches of preservation valuation of natural resources and environment were done in order to create necessary awareness for making optimal decisions in the field of the ways of economic management of these resources and helping to establish sustainable regional development strategy. in this study, preservation value of lilium ledebourii estimated using single bounded dichotomous cho...

The small sample size of contingent valuation (CV) surveys conducted in patients may have limited the use of the single-bounded (SB) dichotomous choice format which is recommended in environmental economics. In this paper, we explore two ways to increase the statistical efficiency of the SB format: (1) by the inclusion of proxies in addition to patients; (2) by the addition of a follow-up dicho...

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...

In this paper, we study starting point bias in double-bounded contingent valuation surveys. This phenomenon arises in applications that use multiple valuation questions. Indeed, response to follow-up valuation questions may be influenced by the bid proposed in the initial valuation question. Previous researches have been conducted in order to control for such an effect. However, they find that ...

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

Abstract The R package DCchoice is designed to mitigate programing-related barriers the application of dichotomous choice contingent valuation (DCCV) methods in empirical studies. Since its release 2014, has been updated. This paper introduces current version which supports single-, one-and-one-half-, and double-bounded DCCVs, with without a spike. Additionally, willingness-to-pay confidence in...

Double bounded dichotomous choice is a contingent valuation elicitation method which involves two iterated binary questions. Past research has compared both responses within the framework of a joint bivariate distribution. In this paper we propose a Bayesian test which allows us to prove the hypothesis of unitary correlation coefficient. The application of the test is conducted on empirical dat...
