摘要：In this paper, the Iranian urban household consumption pattern during 1373-1389 is estimated in the form of almost ideal equations (AIDS). In order to design the model, goods are classified into seven main groups namely, food and tobacco, clothing and footwear, housing and furniture, recreation and entertainment, healthcare, transport and communication, and other goods. In this study, based on microeconomic theory, the share of cost is estimated and own price and income elasticities are stated using economic variables. The data have been extracted from the Central Bank, and all homogeneity, symmetry and Slutsky tests are performed. In this paper, the own price and income elasticities were calculated which indicated that food has the lowest elasticity and transportation has the highest elasticity. Also, according to the data, food, clothing, and housing are listed into the essential goods, and furniture, healthcare, transportation, and other goods are listed as luxury goods for Iranian urban consumers.
