Abstract Converting food waste into animal-feed is highly useful for tackling the problem of food waste, which is particularly severe in developed countries. This study quantified inefficiencies in converting food waste into animal-feed and identified their causes through a data envelopment analysis (DEA) of the monthly input–output data of two producers of animal-feed obtained from food waste in Japan. Our empirical analysis revealed that the producers of animal-feed obtained from food waste (e
This study aimed to investigate whether global air pollution harms human morals beyond physiological and psychological health. To accomplish this, we conducted an original survey involving over 80,000 individuals across 30 countries, inquiring about their recent perceived unethical behaviors. Through regression analyses, we identified global evidence of a positive correlation between local monthly average concentrations of nitrogen dioxide (NO2) and perceptions of unethical behavior.
