An enormous volume of electronic waste (e-waste) is currently being generated in Vietnam, threatening to render this country as an e-waste dumping region. Although the residents play an indispensable role in the e-waste management system, there is presently no or very limited studies available which involve public perceptions on the e-waste recycling in Vietnam. In this study, based on the theory of planned behavior (TPB), the structural equation modeling (SEM) was employed to examine the key factors influencing e-waste recycling behavioral intention of residents in Danang city, Vietnam. Data analyzed from 520 questionnaires revealed that environmental awareness and attitude toward recycling, social pressure, laws and regulations, cost of recycling, and inconvenience of recycling significantly directly affected residents’ behavioral intention, with laws and regulations being the strongest construct significantly to predict individuals’ intention. Of the five above-listed constructs, only inconvenience of recycling had a negative impact on residents’ recycling behavioral intention. Moreover, past experience showed the statistically significant negative effect on the inconvenience of recycling while it had no significant impact on behavioral intention. The influences of demographic variables on recycling behavioral intention were also discussed in this paper. The findings from this research may help policy-makers have a better understanding of residents’ e-waste recycling intention. That is very useful in paving the way for a successful e-waste recycling and management system not only in Vietnam, but also in other countries which are suffering from the same problems of e-waste.

The ASEAN Economic Community (AEC) presents both opportunities and challenges to Shariah-compliant firms (SCF) that have particular rules concerning business activities and financial ratios following Islamic principles. The SCF has to maintain the ratio of interest-based debt to total assets as well as non-permissible income, where these restrictions may impact both firm performance and firm value, particularly in the AEC era. Therefore, the SCF has to utilize internal factors to strengthen the firm while also considering the external factor of macroeconomics. The purpose of this paper is to examine the internal factors—firm age, size and efficiency (FASE), financial leverage, foreign ownership— and macroeconomics affecting financial performance and firm value of SCFs, including the effects both pre- and post-AEC. This study applies structural equation modelling-partial least square (SEM-PLS) to analyze 103 non-financial firms that were continuously listed on the Islamic Shariah Stock Index (ISSI) from 2011 to 2020. The results showed that FASE and macroeconomics had a significant positive influence on firm performance. Moreover, financial leverage, foreign ownership and the AEC participation showed a negative effect on firm performance. In addition, there was a positive relationship between FASE and firm value, as well as firm performance and firm value of SCFs. Finally, the findings from this study may help stakeholders determine policies that involve both internal and macroeconomic situations, as well as the potential effect of the AEC on the enhancement of firm performance and firm value.

BACKGROUND AND OBJECTIVES: The sheer volume of electrical and electronic waste (e-waste) has presently been generated in Vietnam, posing a growing concern regarding its impact can have on the environment and human health. Therefore, the need for developing policies and regulations towards the environmentally sound management of e-waste is becoming crucial. Although the municipalities play an important role in e-waste recycling program, there does not appear to be any study involving residents’ perceptions on e-waste management. This paper aims to examine the influencing factors of end users’ willingness to pay and their payment preferences toward e-waste recycling. METHODS: The logistic regression model was employed to analyze a qualified data set collected through a personal interview survey in Danang city, Vietnam. All analyses were conducted using Statistical Package for Social Sciences software (version 22.0). FINDINGS: The results revealed that the end users’ willingness to participate in recycling programs, laws and regulations, inconvenience of recycling and past experience were four key determinants significantly contributing to the willingness to pay for recycling e-waste. With regards recycling payment methods, most of the participants (36%) were in favor of deposit and refund scheme, while pre-disposal fees and advanced recycling fees came in second and third place (25.8% and 21%, respectively), making monthly payment of recycling fees the least preferred (10.2%). CONCLUSION: These findings may provide policy-makers with crucial information for better e-waste management policy development, which helps address the conflict between development and conservation, may be applicable in Vietnam and other countries as well.
