Estimation and inference in cointegrated demand systems: an application to Tunisian meat consumption
提出一种估计和识别协整需求系统的新方法，并应用于突尼斯肉类需求分析，使用几乎理想需求系统模型和Johansen-Juselius方法检验经济理论约束，通过结构向量自回归模型分析需求弹性的长短期动态。
In this paper, a new framework for estimating and identifying cointegrated demand systems is presented. This method is then applied to the analysis of meat demand in Tunisia with an almost ideal demand system functioning as the underlying model. The Johansen and Juselius approach is used to identify cointegrated vectors as demand equations and to test theoretical economic restrictions. Finally, a structural vector autoregressive model is specified and impulse response functions are calculated to analyse both long- and short-run dynamics of demand elasticities.
