Perceived pollution and health factors raise willingness to pay

What the study found: Households’ willingness to pay for improved urban air quality in Khulna City was associated with perceived air pollution, household respiratory illness, proximity to major roads, and informal occupations. Lower educational attainment reduced willingness to pay, while income and gender were not significant predictors.
Why the authors say this matters: The authors conclude that the findings indicate risk perception, health experience, and exposure shape environmental valuation behavior. They say the results offer local evidence to inform awareness actions and practical financing strategies for improving urban air quality in Bangladesh.
What the researchers tested: The study used face-to-face survey data from 385 households in Khulna City, Bangladesh. Willingness to pay was treated as a binary outcome and analyzed with logistic regression.
What worked and what didn't: About 41.8% of respondents reported willingness to pay. The model showed acceptable discrimination, with ROC-AUC reported as 0.72. Perceived air pollution, household respiratory illness, proximity to major roads, and engagement in informal occupations significantly increased willingness to pay, while lower educational attainment reduced it; income and gender were not significant.
What to keep in mind: The abstract does not describe additional limitations beyond the study’s focus on one city and the use of survey-based self-reported willingness to pay. The summary provided does not include further caveats.
