An application of cointegration theory in the estimation of the Almost Ideal Demand system for food consumption in Bulgaria
将几乎理想需求系统应用于保加利亚消费数据，采用Park的典型协整回归方法进行估计，结果符合理论和消费者行为观察。
Abstract The Almost Ideal Demand system is applied to consumption in Bulgaria. It is argued that the conventional estimation of the Almost Ideal model should be done within the framework of contemporary time series methodology. In this paper, the canonical comtegrating regression procedure of Park is applied. It is argued that the results of the Almost Ideal Demand system that are presented are consistent with both theory and ‘casual’ observation of consumer behaviour in Bulgaria.
