female labor supply and fertility in iran: a comparison be¬tween developed, semi developed and less developed re¬gions

background: female labor supply has been changed dramatically in the recent yr. in this study, we examined the effects of development on the relationship between fertility and female labor supply. methods: we used data of population and housing census of iran and estimated three separate models. to do this we employed logistic regressions (blr). results: the estimation results of our study showed that there was a negative relationship between fertility rate and female labor supply and there are some differences for this relationship in three models. conclusion: when fertility rate increases, fls would decreases. in addition, for higher fertility rates, the woman might be forced to work more because of the economic conditions of her family; and negative coefficients of the fertility rate effects on fls would increase with a diminishing rate.
