    Abstract: We investigated public preferences regarding labelling and sale of genetically modified (GM) products in Poland. A Discrete Choice Experiment (DCE) was used to investigate public preferences and Willingness To Pay (WTP) for new policies changing the current regulations with respect four types of products: food, processed food, commercial products, and pharmaceuticals. In addition to reporting the general results, we analyze the social and behavioral drivers of consumers’ preferences and WTP. The study examines relationship of self-assessed and objective knowledge, perceptions of risks and benefits, and attitudes associated with GMO to consumers’ preferences.

    Abstract: Stated preferences should ideally be elicited in ways providing respondents with economic incentives to report them truthfully—that is, in incentive-compatible conditions. This study aims at testing empirically a novel theoretical approach, which allows for incentive-compatible elicitation of preferences. Choice-matching, proposed by Cvitanić et al. (2019), is applied here to elicit stated preferences towards a public good. While the approach has been originally designed for incentivizing responses to a multiple choice question, we illustrate its possible application to an open-ended question. We conduct an online experiment mirroring a standard stated preference survey as used for valuation of public goods. Two versions of the survey questionnaire are implemented: one employing the incentive-compatible choice-matching approach and another representing a common non-incentivized setting. We find that the open-ended willingness-to-pay values are statistically significantly higher when stated under choice-matching than when expressed in the non-incentivized conditions.

    Abstract: Vietnam is one of the main plastic consumers in the world, yet there is much room for improvement in terms of plastic waste treatment. This study aims to inquire into residents’ awareness and responses to plastic waste, and their willingness to pay for enhancing plastic waste treatment in the North of Vietnam. We employ the contingent valuation method (CVM) and randomly survey 525 households in 25 provinces in Northern Vietnam. Findings suggest that a majority were interested and aware of impacts of plastic waste pollution, 76.8% were willing to contribute to a fund designated for plastic waste pollution alleviation. Residents’ willingness to pay range from VND 900,667 to VND 1,316,088 per household per month. Age, gender, perceived effects of waste pollution, illness due to pollution and care of plastic waste pollution are top factors influencing the households’ voluntary financial contribution to environmental fund. This study provides several evidence-based policy recommendations to improve the quality of plastic treatment in the North of Vietnam.
