Analysis of the Dynamics in the Relationships between the Consumption of Various Types of Fresh Meat by Japanese Households

Hideo Noda and Koki Kyo
Abstract— What kinds of relationships exist among the growth rates of consumption of beef, pork, and chicken in Japan? This paper studies the dynamics of fresh meat consumption using monthly data from January 1990 to March 2014 from Japan’s Agriculture & Livestock Industries Corporation. First, a time-varying coefficient vector autoregressive model is constructed for a time series of fresh meat consumption, and its parameters are estimated using a Bayesian method. The time-varying power contribution and time-varying covariance function for the time series are then obtained based on the estimates for the model. The results show that the power contribution to the consumption of chicken from that of beef is very significant. The consumption of beef gives a stronger power contribution to that of pork at lower frequencies. Furthermore, the consumption of pork gives a stronger power contribution to that of chicken at lower and higher frequencies, and especially the latter in recent years.

Index Terms— Bayesian modeling, fresh meat consumption, time-varying coefficient, VAR model.
