Estimation of Welfare in Iran Provinces: A Non-Paretian and Decomposition Welfare Function Approach to population

In this study, cardinal index of the age and welfare function elasticity are used to evaluate the social welfare compared to efficiency and inequality in Iran Provinces. The results indicate that Tehran, Bushehr, Markazi provinces have the higher welfare coefficient and Sistan and Bluchestan and Kurdestan provinces have the least rate of welfare in Iran. Also, the findings reveal that there are no significance relation between the rate of welfare and population in Iran provinces. So, it is proposed that the welfare index can be improved by increasing income in some provinces like Tehran, Isfahan, Khoozestan and Khorasan-e-Razavi, but by the reduction of inequality level in some other provinces such as Yazd and Hamedan.
