The thesis contains three self-contained chapters. The first chapter of the thesis studies the interaction between informal risk sharing and network size, and its impact on decision to migrate. I study the importance of informal network size, and network income with a focus on disadvantaged communities in India. In the next chapter, I analyse how reducing credit market imperfection for the migrant household effect their well-being. I focus on gender of the loan applicant in the migrant households at the place of origin. The third chapter studies the unintended consequence of large scale education programs on the age at marriage of women. Age at marriage plays a significant role in the well being of the women. We provide causal evidence in this chapter to estimate the impact of women’s education. We also study the differential impact on age at marriage due to outside option (wages).
