Big Data and Dietary Trend: The Case of Avocado Imports in China

ABSTRACT

The advancement of data science and technology presents a unique opportunity to understand rapidly evolving dietary trend around the world. In this case study, we show that the Baidu index, a measurement of the intensity of user searches for specific words, helps explain and forecast the growth of avocado imports in China. Specifically, we find that China’s avocado imports rise by 8% in response to a 10% increase in the Baidu index. Furthermore, the inclusion of the Baidu index in a standard demand model reduces the prediction error by 2.7%.
