چکیده:
Comparison of the private consumption extracted from the Household Budget Survey and the National Accounts in Iran reveals that not only the latter always exceeds the former, but also the gap between them has increased over time. In this paper we propose a method to eliminate the discrepancy between these two sources. We integrate the micro and macro data and compare the poverty indicators in Iran for 1991-2007. Then we decompose the poverty changes over time according to socioeconomic characteristics of Iranian households into the exact sum of three independent components, i.e. growth, inequality and population effect. Results show that the total poverty changes in Iran in the previous years have been most affected by the growth effect and least affected by the population effect. The growth and overall effects have always had the same direction in the previous years in Iran.

"Poverty Decomposition Based on Iranian Households’ Socioeconomic Characteristics: Integrated Micro and Macro Approach Farhad Nili1 and Sohail Poursadeghi Haghighat2 ABSTRACT Comparison of the private consumption extracted from the Household Budget Survey and the National Accounts in Iran reveals that not only the latter always exceeds the former, but also the gap between them has increased over time.
g. the Gini coefficient or any other inequality index, into these models, one may conclude that these studies suffer from the specification problem We will show in this section that we can decompose the poverty changes into the sum of three exact independent components over time: Growth Effect, which shows proportional changes in the mean expenditures of all households without any change in the distribution Inequality (or Distribution) Effect, which shows changes in the distribution, without any change in the mean Population Effect, which captures the effect of changes in the population share of different socioeconomic groups caused by change in the total population or mobility of different groups.
4. Data and the Model The main idea of this study is firstly to measure the poverty index in Iran during 1991-2007 by integrating micro and macro data, and then decomposing the changes in poverty into three separate components of growth, inequality and population effects when we take time interval for all the decompositions equal to two years."
