A Hypothetical Test on the Interdependence of Two Subsequent in the Double Bounded Contingent Valuation Method

양분형 조건부가치평가에서 응답간 상호종속성에 대한 가설 검정

Even though the double bounded contingent valuation method(DBCVM) is an efficient estimation method of the willingness to pay for a non-market good, it has long been criticized to be an inappropriate estimation method because of interdependence of subsequent two answers during a course of survey. Many experimental studies have reported that two subsequent answers are not made independently, but the second answer depends upon the first answer. There are many hypotheses contending a different pattern of dependence of the answers. In this study, the dependence of two answers are tested. But no dependence pattern has been detected.
