| Outline of Final Research Achievements |
This research shows that, after the media coverage of radioactive contamination, Japanese household demand shifted form fresh fish to fresh pork, that fresh beef was more expenditure-inelastic, that fresh fish and fresh pork was more expenditure-elastic, that the decreasing trend of fresh fish demand was lost, that the trend of fresh pork demand changed from increasing to decreasing, and that the distance from the nuclear power plant decreased fresh fish demand and increased fresh chicken demand. This research also provides a new flexible, integrable, linear demand system that can generate realistic elasticities using big data, which existing models cannot estimate properly.
