How environmental beliefs influence the acceptance of reallocating government budgets to improving coastal water quality: a hybrid choice model

Abstract

ABSTRACT In this study, we analyse how beliefs concerning environmental action influence choices in a stated preference survey on coastal water quality and marine habitat areas. Survey respondents were presented with a series of choice tasks featuring improvements in water clarity, reef health, seagrass area and a series of costs in the form of reallocated state budget against a baseline of no new improvements and no change in the budget. The reallocated budget scenario was used as it is likely to be realistic to respondents. Estimates of willingness to reallocate were obtained using a hybrid choice model which included the choice data, attitudinal data regarding support for environmental action and sociodemographic characteristics. Our results suggest that beliefs supporting environmental action influence the willingness to reallocate for attributes that change coastal water quality. A decision support tool for policy analysts was developed to illustrate how public support, as a probability of supporting reallocation, is shaped by beliefs and changes with sociodemographic characteristics.
