Article InfoGiven the adverse effects of air pollution on human health, a lot of studies have empirically investigated the causal effect of air pollution on health. However, no study has considered how fine particulate matter interacts with GDP per capita to affect cancer mortality. This study therefore uses data for 20 OECD countries to estimate the conditional effect of air pollution on cancer mortality. To this end, a fixed effect panel regression model which takes both country and time fixed effects into consideration is estimated. The conditional causal effect of fine particulate matter was found to be negative 0.22 and significant at 1% level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
