||Seifeddine Ben Taieb, Effects of Health Consciousness on Olive Oil Consumption in Japan -Analysis of Scanner Data Using a Hierarchical Bayesian Approach-, European Association of Agricultural Economists (EAAE), 2021.07, [URL], The olive oil market in Japan has been growing at a fast pace since the late 90s. Indeed, the olive oil is now one of the most consumed oils in Japan. However, this growth in popularity remains unexplained. Indeed, our knowledge on the Japanese consumer of olive oil is pretty limited. In this research, we studied the effect of the health consciousness on the consumption of olive oil. To do so, a hierarchical Bayesian model, with a tobit base, was employed to analyze scanner panel data. These data were combined with attitudinal data that were collected through a survey. The results showed that consumers with a high level of health consciousness do indeed buy more olive oil than those who are not health conscious. Additionally, the health status of consumers had a significant effect on consumption, indeed, consumers suffering from diabetes buy smaller amounts of olive oil..
