Estimating households’ willingness-to-pay associated with risks for improved plastic waste management using a new integrated contingent valuation-mindsponge- mindspongeconomics approach

This study investigates Vietnamese citizens’ participation in plastic waste treatment and environment improvement. We developed and adopted a novel method (CVMM) that integrates the contingent valuation, mindsponge, and mindspongeconomics – a new type of economics to estimate and reasonate households’ financial contribution for improved plastic waste treatment in North Vietnam. CVMM analytics were used to explore 1103 observations surveyed during 2022-2023 in the North Vietnam. The empirical findings suggest that public-private partnership should be further expanded and/or strengthen to improve finance while stronger environment policy associated with environmental education should be taken to improve environmental literacy and build environmental culture, which ultimately help address plastic waste and environmental issues in the long run.
