he relationship between birth order and child's human capital is studied in this paper. A Microeconomic model is designed to analyze the intrahousehold behavior on resource allocation and its outcomes for children. Since adding up a child changes the method of intrahousehold resource allocation, the expenditures of investment in child's human capital has been changed too. The aim of this paper is to investigate the effect of birth order on educational achievement which measured by average of scores and score of math as two measures of educational quality and by years of schooling as a measure of quantity of education. In general, five samples from Tehran are used: the first includes primary students in grade 4 and the second and third samples cover single persons (male and female) who are at least 20 years old. The fourth and fifth samples include married persons (male and female) who are at least 35 years old. According to these data, the regression analysis is used to present evidence and test hypothesis. Results suggest that the increase of birth order reduces both the quantity and quality of children's education in the sense that the latest children have lower level of education than the earliest ones.

The aim of this paper is toinvestigate the effect of birth order on educational achievement which measured by average of scores and score of math as two measures of educational quality and by years of schooling as a measure of quantity of education.
Since the latest child has been born in a more crowded family than the former child and family's resources per person have been narrowed, the hypothesis is as follows: birth order has negative effect on educational performance of children.
2. Theoretical Literature Different discussions and reasoning have been proposed to explain the effect of birth order or the position of a child among other children in the family on the abilities of that child.
The prominent point is that not only in their latter model but also in the former, the endowments of children was initially considered different and then some reasons proposed to indicate that the child who has higher income what birth order he/she has.
Because adding to the number of children is realized in the length of time, when parents purchase education for child with higher birth order (jth child), they confront higher price ( s s p j pi ) while all other things (such as earning and importance of education in parents’ viewpoint) being equal.
However, the positive effect of birth order in old cohorts cannot reject our hypothesis because adult individuals have independency in their life and live far from their parental family and themselves can determine their educational quality.
