Abstract

This study examines the marginal abatement costs (MACs) of three water pollutants (BOD, COD, and TSS) in the seafood processing industry in the Mekong River Delta of Vietnam. Using data on production activities and pollutant concentration, we estimate the MACs and analyze their relationship with firm characteristics. The results reveal significant heterogeneity in MACs, with younger firms, less labor-intensive firms, LLCs and joint-stock companies, firms located in seashore or riverside areas, and those with ISO or other certifications exhibiting lower MACs. These findings suggest that a uniform standard or environmental fee may not efficiently address pollutant reduction. Instead, a tradable permit system could be a more effective approach.
