An application of cointegration theory in the estimation of the almost ideal demand system for food consumption in Bulgaria
将协整方法应用于保加利亚食品消费的近乎理想需求系统估计，发现结果与理论和消费者行为观察一致。
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 cointegrating 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.
