Allias和Nichèle(Eur Rev Agric Econ,34(4):517-538,2007)通过扩展汉密尔顿(Econometrica,57(2):357-384,1989)的思想,提出了一个马尔可夫转换的几乎理想需求系统(MS-AIDS)模型。在本文中,我们提出了一个贝叶斯估计的MS艾滋病模型,并说明我们所提出的方法的适用性。然后,我们运行两组仿真研究,以确认所提出的方法的有效性。在对日本肉类市场的实证研究中,我们的贝叶斯估计提高了所有肉类产品的MSE,同时成功地捕捉到了与日本和美国牛海绵状脑病病例发生时间相一致的肉类需求的变化。
Allias and Nichèle (Eur Rev Agric Econ, 34(4):517–538, 2007) proposed a Markov-switching almost ideal demand system (MS-AIDS) model by extending the idea of Hamilton (Econometrica, 57(2):357–384, 1989). In this paper, we propose a Bayesian estimation for MS-AIDS model and illustrate applicability of our proposed method. We then run two sets of simulation studies to confirm the validity of the proposed method. In the empirical study on the Japanese meat market, our Bayesian estimation improves the MSEs for all meat products over the ML estimation, while successfully capturing the regime shifts of meat demand coinciding with the timing of bovine spongiform encephalopathy cases in Japan and US.
